Surfactants are present in a wide range of cleaning products, and one of the usual groups is anionic surfactants, which are particularly valued for their foaming ability.
There is a multitude of anionic surfactants for use in detergents, although the most commonly used today are the salts of dodecylbenzene sulfonic acid and ethoxylated sodium lauryl sulfate.
Conversely, new trends have led to a rethinking of the suitability of these surfactants, due to factors such as hazardous or difficult handling, biodegradability, compatibility with skin and fabrics, efficiency in low-temperature washing, or transport costs linked with diluted products.
For this reason, ingredients developed in the last century such as Alpha-Olefin Sulfonate (INCI: Sodium C14-16 Olefin Sulfonate), are once again of interest in the detergency and cosmetic sectors.
Alpha Olefin Sulfonate is an anionic surfactant that has been used efficaciously for many years in laundry and personal care products.
The chief benefits of Alpha Olefin Sulfonate in cleaning products are its great capacity to form stable foams, even in diluted products, in hard water and at low temperatures, good cleaning properties, useful in both detergents and cosmetics, fast biodegradability, good compatibility with the skin, and its high-water solubility.
It is therefore making it suitable for liquid or powder detergents and personal hygiene products, and especially for hand dishwashers, laundry detergents, automotive cleaners or bath gels.
The most common Alpha Olefin Sulfonate(AOS) used in personal care is sodium C14-16 olefin sulfonate, which functions as a detergent, wetting agent and also as an emulsifier.
When properly formulated, sodium C14-16 olefin sulfonate imparts viscosity, a consumer-acceptable foaming profile and quick flash foam to produce a stable lather, among other benefits.

Production and composition
α-Olefin sulfonates are produced by sulfonation of alpha-olefins, typically using sulfur trioxide. Subsequent alkaline hydrolysis gives a mixture of alkene sulfonates (60-65%) and hydroxyalkane sulfonates (35-40%).
Description
In addition to a longer hydrocarbon chain in which there must be at least one double bond (hence the name “olefin”), it has an anionic sulfonate headgroup with a sodium ion as a counterion.
The sulfonate group is negative in aqueous solution, which is why the α-olefin sulfonates are among the anionic surfactants.
In contrast to most other surfactants in which the C12-alkyl chains have the highest surface activity, olefin sulfonates shows maximal activity when using C14and C16-olefins.
Usage
α-Olefin sulfonates with linear alkenyl radicals from C12 to C18 are used as anionic surfactants in various areas of application due to their pronounced foam formation and foam stability (even with high water hardness), excellent fat-dissolving power and oil dissolving power as well as a favorable ecological profile and low aquatic toxicity and human toxicity.
They are being used for example in detergents and cleaning agents, for degreasing, in the emulsion polymerization, the conditioning of concrete and mortar as well as in the formulation of pesticides.[2]
In some shampoos sodium C14-16 olefin sulfonate is being introduced as an alternative for sodium laureth sulfate without sulfate.
Sodium Alpha Olefin Sulfonate
Sodium Alpha Olefin Sulfonate is a strong blowing agent, as well as a wetting and plasticizing agent for ready-made mineral plasters (adhesive and machine plasters), masonry mortars and putties.
The air pores created by Sodium Olefin Sulfonate are stable and significantly reduce shrinkage and associated cracking, especially for cement and cement-lime mortars.
Another advantage is high frost resistance and reduced efflorescence from the solution.
Sodium Olefin Sulfonate is also suitable for the production of plaster and masonry mixtures, as well as as the main product in the production of strong blowing agents in the industry of additives to building materials (for example, products for the production of foam concrete, etc.).
Sodium Olefin Sulfonate provides quick wetting and dispersion of building mixes (e.g. for machine application of plasters), reduced tack and therefore easy processing and improved pumping properties.
Clotting, for example with fine building mixes, can be significantly reduced or eliminated with Sodium Olefin Sulfonate.

Definition and Structure
By definition, olefins are alkenes (unsaturated aliphatic hydrocarbons) obtained by cracking naphtha or other petroleum fractions at high temperatures.
Alpha-olefins are particularly reactive because the double bond of the alkene is on the first carbon of the chain.
Sodium AOS is a mixture of long chain sulfonate salts prepared by sulfonation of C(x-y) alpha-olefins where (x-y) represents the range of the carbon chain length (Wenninger and McEwen 1995a; 1995b).
The mixture consists primarily of sodium hydroxyalkane sulfonates and sodium alkene sulfonates
Sodium C14-16 AOS is identified in Japan as sodium tetradecenesulfonate or sodium tetradecenesulfonate solution
Method of Manufacture
Although alpha-olefins can be produced by cracking of paraffin wax as noted, the limited availability of waxy crudes prevents large-scale use of the technique.
For industrial use, a-olefins are synthesized by oligomerization of ethylene.
Using continuous falling film techniques, the a-olefins are sulfonated with gaseous sulfur trioxide; typically a sulfur trioxide :olefin molar ratio between 1.0 to 1.2 is used.
The sulfonation produces alkenylsulfonic acid and intermediate sultones as well as other by-products.
At this stage of the process, the sultone content increases at the expense of alkylsulfonic acid upon standing.
If the mixture ages too long, 1,4-sultone may be produced
SODIUM ALPHA-OLEFIN SULFONATES
It is more difficult to hydrolyze than either 1,2 or 1,3-sultone (KirkOthmer 1983).
The continuous falling film process limits contact time, temperature, molar ratio, and feed rates to eliminate undesirable side products formed during residence time (Schoenberg 1980).
The acidic reaction mixture is neutralized and then hydrolyzed with an excess of sodium hydroxide to saponify the intermediate alkane sultones (some of which may be mild skin sensitizers) (Roberts and Williams 1983).
The conditions of hydrolysis determine whether hydroxyalkane sulfonates or alkene sulfonates are the favored products.
The process yields AOS mixtures of 60-65% alkene sulfonates, 30-35% hydroxyalkane sulfonates, and 5-10% disulfonates.
Roberts et al. (1987) stressed that hypochlorite bleach should not be used in the manufacture of the Sodium AOS so as to avoid producing certain unsaturated and chlorosultones as byproducts. These compounds are undesired by-products as they have been demonstrated to be highly potent skin sensitizers.
According to Ter Haar (1983), since 1973 the bleaching step in the production of AOS has been carried out at high pH to avoid the formation of hypochlorous acid (which subsequently reacts with alkene sulfonates to form chloro gamma and delta sultones), confirming the view of Roberts and Williams (1983) that knowledge of the chemistry of sultone formation allows them to be avoided in the manufacture of AOS.
Impurities Stepan Company (1995) reports their internal specifications for Sodium AOS include a 31 ppm maximum for 1,4-sultones (delta sultones).
Techniques for sultone detection include separating and concentrating sultones from the surfactant via thin layer chromatography (TLC) followed by high performance liquid chromatography (HPLC) quantification.
This technique has a sensitivity of 0.1 ppm and can go as low as 0.01 ppm when background does not interfere (MacMillan and Wright 1977).
Another technique uses preparative HPLC followed by gas chromatography-mass spectrometry (GC-MS) and has a sensitivity of 2 ppb (Matsutani et al. 1986).

Process for the production of commercial alpha olefin sulfonates
Abstract
Alpha olefin sulfonates generally commercially made by reacting SO3 with alpha olefins followed by neutralization and saponification with base (typically sodium hydroxide), and subsequently bleaching, characteristically may contain by-product impurities which are non-sulfonate sulfur containing organic compounds.
These impurities chiefly sultones, can be substantially completely eliminated by the process sequence of the present disclosure which involves heating and bleaching and pH adjustment under specified conditions. Surprisingly, such and similar organic sulfurous impurities are eliminated during such heating and do not reform under such bleaching and pH adjustment.
Description
BACKGROUND OF THE INVENTION
Alpha olefin sulfonates are commonly manufactured by reacting alpha olefins with sulfur trioxide utilizing falling film technology as taught by Knaggs et al U.S. Pat. No. 3,169,142 followed by neutralization in an aqueous medium containing alkali metal hydroxide. In addition to alkali metal sulfonates, the initial resulting product also characteristically contains unreacted olefins and sulfur containing organic components, chiefly sultones, which are not alkali metal sulfonates.
For purposes of maximizing conversion levels of alpha olefins to alpha olefins sulfonates, of minimizing to the point of elimination the presence of non-sulfonate sulfur containing components, and of bleaching, since such intermediate products are characteristically too dark in color for commercial acceptability, and so must be bleached, prior art alpha olefin sulfonate manufacturing technology fails to provide adequate teachings or suggestions. When bleaching is undertaken by the prior art technology, sulfur containing organic components which are not alkali metal sulfonates are actually produced as by-products, adding to any undesirable components already present.
In the present context (except where stated or implied in a narrower sense) the term “alpha olefin sulfonate(s)” is used in its broadest commercially accepted sense to include not only 1,2-alkene-1-sulfonates, but also generally a broad mixture of alkenyl sulfonates, hydroxyalkane sulfonates, poly (primarily -di-) sulfonates, hydroxy alkenyl sulfonates, and similarly related sulfonates; such so-called commercial alpha olefin sulfonate products also contain quantities of hydrocarbons, alpha olefins and isomerized olefins, aliphatic alcohols, and lesser quantities of other by-products and unreacted matter, as well as, inorganic species, all in an aqueous system.
BRIEF SUMMARY OF THE INVENTION
The present invention is directed to an improved process for making the biodegradable alpha olefin sulfonates surfactants.
A primary aim of this invention is to substantially completely eliminate all sulfur organic components in an alpha olefin sulfonate product which are not alkali metal sulfonates. Since the vastly predominant sulfur containing non-sulfonate species, and the most difficult to eliminate sulfur containing non-sulfonate species are sultones, a primary air of this invention is to provide a process adapted for substantially completely eliminating sultones in an alpha olefin sulfonate product.
Another air of this invention is to substantially completely eliminate the presence of all sulfur containing organic by-product components, sultones, which might otherwise be present in a bleached alpha olefin sulfonate product by converting such components into alkali metal sulfonates, and also by preventing the redevelopment of such by-products, and other similar product components, in such a bleached product.
One achievement of this invention is a maximum of the conversion of sulfonated alpha olefins to sulfonates in the manufacture of alpha olefin sulfonate detergents.
Another aim of this invention is to provide an alpha olefin sulfonate product containing substantially no sulfur containing organic components which are not alkali metal sulfonates.
Such non-sulfonate sulfur containing components serve no functional purpose and not only tend to reduce the level of desired sulfonates in a given surfactant, but, in addition, such sulfur containing organic components, at least in some instances, can exert undesirable effects upon alpha olefin sulfonate products.
For example, certain sulfur containing organic components act as antifoam agents if present in sufficient quantities.
Further, certain such sulfur-containing components can slowly hydrolyze causing product pH shifts.
The invention provides a bleaching technique for aqueous alkali metal sulfonates which have been previously treated to substantially eliminate all sulfur containing organic components in such an alpha olefin sulfonate material, which components are not alkali metal sulfonates.
Not only is the reformation of such non-sulfonate impurities surprisingly substantially completely prevented during bleaching, but also the bleaching efficiency of a bleach, such as sodium hypochlorite, is unexpectedly improved.
The invention further provides a technique whereby, first, by the action of heat, all sulfur containing organic components in an alpha olefin sulfonate product which are not alkali metal sulfonates are substantially completely eliminated, and then this resulting product in a specified reaction sequence by the action of a combination including bleach, pH, and temperature, is lightened in color substantially without reforming or generating any sulfur containing organic components in such alpha olefin sulfonate product, which components are not alkali metal sulfonates.
Another aim of the invention is to eliminate from alkali metal alpha olefin sulfonate products sulfur containing impurities belonging to the class of organic compounds known generally as sultones because such compound class, or members thereof, may have undesirable side effects, including some as indicated earlier.
Other and further objects, aims, purposes and advantages of the present invention will be apparent to those skilled in the art from a reading of the present specification taken with the accompanying drawings.
More specifically, the present invention relates to an improvement in a process for making alpha olefin sulfonates by the known prior art method of first contacting a stream of vaporized sulfur trioxide diluted with an inert gas, usually air, with liquid alpha olefins containing from about 8 through 24 (preferably from about 12 through 18) carbon atoms per molecule followed by admixture of the reaction product with aqueous alkali metal hydroxide. In the process of the present invention, the resulting aqueous liquid phase system is heated at a temperature of from about 95° to 190° C (preferably from about 150° to 180° C) while maintaining such system under autogenous pressure of from about atmospheric to about 230 psig (preferably from about 120 to 160 psig) for a time sufficient to substantially completely eliminate sulfur from residual oil in such system (which means, in effect, that all non-sulfonate sulfur containing organic compounds have been substantially eliminated from such system). Such heating is conducted while maintaining sufficient dissolved free alkali metal hydroxide present in such system at a level to produce a system pH in the range of from about 12.0 to 14.0 (and preferably in the range of from about 12.3 to 13.0).
Thereafter, one cools the resulting so-heated system to a temperature below about 60° C (and preferably below 5° C) and then contacts such so-cooled system under liquid phase aqueous conditions with the bleaching agent sodium hypochlorite. The total amount of such bleaching agent (active ingredient basis) used ranges from about 0.1 to 6 weight percent of the total weight of alkali metal sulfonated products present in such resulting so-heated system (and preferably from about 0.5 to 2.0 weight percent). Such contacting is conducted while maintaining such resulting so-heated system at a pH in the range of from about 12.0 to 14.0 (and preferably from about 12.3 to 13.0). Also, such contacting is further conducted while maintaining such resulting so-heated system as a temperature of from about 25° to 60° C (and preferably from about 35° to 50° C). Such contacting is conducted for a time sufficient to produce a Klett color of about 180 or less (and preferably about 130 or less) at 5 weight percent total sulfonate of alpha olefin sulfonate in water. Such contacting is conducted as a practical matter for a time which is either sufficient for complete reaction of added sodium hypochlorite with color bodies or is sufficient for achievement of a desired product color level.
Excess bleach remaining after a bleaching operation optionally can be destroyed by the addition to bleached product of an antichlor (reducing agent), such as sodium sulfite, sodium bisulfite, or the like. Subsequent product pH adjustment may be desirable. If, in fact it is intended to adjust the product pH to a lower level, it is necessary to first completely react or destroy all residual bleaching agent prior to pH adjustment with acids (such as sulfuric and the like), as those skilled in the art will readily appreciate.
Comparison of surface and interfacial properties of internal olefin sulfonates (IOS) and alpha olefin sulfonates (AOS) shows that hydrocarbon chain branching has a significant influence on interfacial properties at the air–water, pentadecane–water and parafilm–water interfaces.
The isomeric branched IOS shows a higher critical micelle concentration and are more effective in reducing the surface tension at the air–water interface by occupying a larger area per molecule. IOS exhibits better dynamic air–water interfacial properties due to a lower meso-equilibrium surface tension.
The equilibrium interfacial tensions for AOS and IOS have no remarkable difference at the pentadecane–water interface.
The water wettability and electrolyte tolerance are enhanced with branched hydrocarbon chain olefin sulfonates.
Owing to its performance attributes and biodegradability, alpha olefin sulfonates are set to become the material of choice in a range of applications.
Alpha olefin sulfonate is an anionic surfactant with excellent viscosity and foaming characteristics which offers enhanced detergency and foamability.
High pH stability of alpha olefin sulfonates will generate additional interest over other types of sulfonates such as lauryl sulfates and lauryl ether sulfates creating a progressive environment for the market.
Being an anionic surfactant, it is able to function as detergent, wetting agent and as an emulsifier in broad range of applications.
Alpha olefin sulfonates offer other bundled benefits including high foaming profile and a quick flash foam to produce a stable lather.
Alpha olefin sulfonates also allow personal care products to be offered as preservative-free aqueous solutions, due to which detergent & liquid soaps application is set to remain key consumer of alpha olefin sulfonates in the market.
Alpha Olefin is an olefin featured by the position of solid bond (reactive unsaturation) at the two end carbons in carbon chains.
Alpha olefins and their derivatives are used as comonomers in polymer such as low density polyethylenes for the properties of lighter, thinner, better flexibility and more tearing resistance.
They are used in the production of linear plasticizers, oxo-alcohols, motor fuels, lubricants, automotive additives, biodegradble surfactants, paper size, and in a wide range of specialty applications in the production of mercaptans, flavors and fragrances, alkyl metals, halides, alkyl silanes.
Alpha oLefin sulfonates are products of the sulfonation of alpha olefins and are long chain compounds.
Alpha olefin sulfonates are manufactured by processes such as ethylene ologomerization, or by the Fischer-Tropsch process of synthesis.
Firstly, alpha olefins are sulfonated inside a continuous thin film reactor, which produces a mixture of cyclic sulfonate esters (sultones) and alkene sulfonic acids.
Aqueous sodium hydroxide is then used to neutralize this mixture.
Carrying out hydrolysis at high temperatures, the remaining sultones are then converted into hydroxy sulfonates and alkene sulfonates.
Alpha olefin sulfonates are then obtained in the form of an aqueous solution.
For the manufacturing of alpha olefin sulfonates in the solid form, neutralization and hydrolysis are carried out in isopropanol, and not water.
The quality of alpha olefin sulfonates critically depends upon the purity of the alpha olefin feedstock.
The sodium salts of alpha olefin sulfonates are widely used in various consumer-oriented and industrial products because of their unique surfactant properties.
Based on the average length of the carbon chains contained in alpha olefins, the sodium salts of alpha olefin sulfonates that are commercially available include Sodium C12-14, Sodium C14-16, Sodium C14-18, and Sodium C16-18 olefin sulfonates.
These products exhibit distinct physical properties, and are accordingly used for suitable applications.
On the basis of application, the alpha olefin sulfonates market can be segmented as:
Soaps & Detergents
Personal Care Products
Lubricant Additives
Others (Pesticides, Construction Chemicals, etc.)
Alpha olefin sulfonates are widely utilized in a number of applications, primarily as active surfactants. Alpha olefin sulfonates exhibit beneficial properties such as excellent foaming, wetting and cleaning ability, high detergency, and good degreasing ability. Also, alpha olefin sulfonates are highly compatible for use with other anionic, amphoteric, as well as non-ionic surfactants. Alpha olefin sulfonates are mild on human skin and do not cause irritation, making them suitable for use in products such as soaps, shampoos, hand wash liquids, etc. Moreover, alpha olefin sulfonates are as effective for use in hard water as in soft water, thus expanding their scope of application. Another important factor aiding the increasing application of alpha olefin sulfonates is the biodegradability of the compounds. Alpha olefin sulfonates are thus more eco-friendly than many other commercial surfactants. Apart from personal care products and consumer goods, alpha olefin sulfonates are also used in industrial applications, such as in the formulation of lubricants; manufacture of industrial cleaners, metal working fluids, drilling fluids in the oil & gas industry; and the formulation of certain agrochemical products such as pesticides. Thus, the market for alpha olefin sulfonates is expected to be driven by their superior performance as surfactants as compared to other compounds such as linear alkylbenzenesulfonates (LAS), alcohol ethoxysulfates, and alcohol ethoxylates.

Anionic Surfactants
Alpha Olefin Sulfonates
Alpha olefin sulfonates (ADS) are efficient readily biodegradable cleaning agents that possess a high degree of chemical stability and have good water solubility characteristics. ADS usage in consumer products in the U.S. today is mainly in liquid hand soaps with minor use in shampoos. ADS use outside the U.S. has principal consumer applications in household cleaning and per.:;onal care products. Current estimates indicate that ADS represents approximately I% of the total anionic surfactants utilized worldwide. ADS products are mixtures of two major components: sodium alkene sulfonates and hydroxyalkane sulfonates with the sulfonate group in the tenninal position and the double bond or hydroxyl group located at various positions along a linear aliphatic chain. Although actual data are limited. and the biodegradation pathways for ADS are not well defined, these compounds appear to be readily biodegraded under both laboratory and environmental conditions. For example. influent sewage containing about 2% ADS as a fraction of lotal surfactant content has been shown to be completely cleared of ADS during passage through a sewage ueaonem plant. In tenns of ADS impact on water quality, there are presently no standards in the U.S. or Europe specifically referring to alpha olefin suIfonates. If present, these anionic surfactants are included among those measured in the environment using the MBAS method. ADS is not specifically monitored in either the U.S. or Europe. Aquatic toxicity data report LCso values in fish ranging from 0.3mg/L to 21 mg/L, with the harlequin fish being the most sensitive. Longer-chain ADS compounds are consistently more toxic than those with shorter alkyl chains. Daphnia magna is the only invertebrate that has been tested, and LCso values range from 7.0 mgIL for Cl6-18AOS to 18.0 mg/L for CI4_16ADS. Little infonnation is available on the subacute or chronic effects of ADS on aquatic organisms. The gills appear to be the primary site of ADS toxicity. Toxicity is directly related to changes in interfacial tension between the gill and water, since oxygen absorption is thought 10 be severely hindered when the tension decreases beyond a cenain critical point. Protein complex fonnation between dissolved surfactants and gill surface tissues was thought to be another primary mode of action. 14C_ADS accumulates primarily in the gills and secondarily in the gall bladder. iii The only study found concerning the toxicity of ADS to plants showed no significant effect on the germination or growth of tomato, barley and bean plants watered with solutions of 10. 25, or 40 mg/L AOS. The mammalian toxicity data that are available for ADS at doses far in excess of nonnal use levels and the relative ease of ADS biodegradation indicate that the use of these surfactants does not pose a significant hazard to human health. Their safety is recognized by the Food and Drug Administration which has approved their use as indirect food additives. The ammonium. calcium. magnesium. potassium and sodium salts of ADS are approved for use with the stipulation that the alkyl group is in the range of ClO38 with not less than 50% in the range of C14 – 16. The alpha olefin suIfonales exhibit a moderately low order of toxicity in rodents. ADS is slightly to severely irritating to rabbit skin depending on concemration. Skin sensitization observed in guinea pigs has been attributed to the presence of unsaturated 1,3-suhones and chlorosuhones. These sultones are not nonnally present in commercial formulations. ADS concenuations of 1% are not ocular irritants in rabbits, but concenuations grealer than 5% are capable of producing severe ocular damage. A single set of mutagenicity experiments showed a positive response in a host-medialed assay with rats; however, the response may be due to minor components in the sample tesled. All other mutagenicity studies are negative. With respect to teratogenic effects. an increase in cleft palates was found in offspring of mice given 300 mg/kg of ADS by gavage during gestation as well as an increased incidence of minor skeletal anomalies in both mice and rabbits at this dose level. However. these responses occurred only at doses where the dams exhibited toxic responses and are not considered to be primary effects of ADS. Carcinogenicity studies have yielded negative results.
AOS is readily absorbed after oral adminisuation [0 rats. It is primarily excreted in the urine. The metabolic fate of orally and inuavenously administered AOS was studied in male Wistar rats. After oral administration, about 80% of 14C-ADS was rapidly absorbed from the gastrointestinal tract. The blood level peaked at 3 hours. Within 24 hours of the dose. 72% was excreted in the urine and 22% in the feces, some of which may have resulted from primary biliary excretion. Mter intravenous injection, 50% of the dose was excreled in the urine within 1 hour and 90% appeared in the urine within 6 hours. These results suggest that no accumulation of 14C_ADS occurs and that it is rapidly absorbed. metabolized and excreted. iv The percutaneous absorption of He-labeled ADS has also been studied in male Wistar rats under various conditions. Absorption through the intact skin is minimal. Application to the intact dorsal skin resulted in the absorption of 0.6% of the applied dose, while application of the same volume to damaged skin increased absorption SO-fold. In human volunteers, negligible to mild skin irritation was observed in 24-hour patch tests with 1-2% active ADS samples. Also in humans, increased irritation was nOled as the study progressed in a 10 day occlusive patch test with a 0.8% active concentration of ADS. Positive sensitization responses reponed in one study have been attributed to the presence of unsaturated 1,3-sultones which are not oonnally present in commereial formulations.
Surfactants are compounds commonly used in detergents that, when dissolved in a liquid such as water, reduce that liquid’s surface tension. Anionic surfactants ionize and carry a negative charge when added to water. This results in binding with positively charged particles within the water, improving the surfactant’s effectiveness at removing dirt and oil.
Alpha Olefin Sulfonate is a type of non-sulfate anionic surfactant widely used today in shampoos and other bath products due to its skin mildness, cleaning and foaming characteristics and its ability to mix well with water to remove dirt and oils. C14-16 olefin sulfonate is the most commonly used variation, with 14-16 indicating the average carbon chain length. It is generally produced in industrial quantities via petroleum cracking.
AOS-40 is a 40% solution of C14-16 olefin sulfonate used in a variety of household and personal care soaps and detergents. It exhibits several beneficial attributes that make it a popular active ingredient:
Stable over a wide pH range
Rapidly biodegradable
Cold water soluble
Hard water compatible
Mild on skin
Good foaming agent
Compatible with other surfactants
Can be used for sulfate-free products
Sodium C14-16 olefin sulfonate
Application
1.Sodium C14-16 olefin sulfonate can be widely used in phosphate-free washing powder, liquid detergents and other household cleaning products and textile printing and dyeing industry, petroleum chemicals, industrial hard surface cleaning aspect.
2.An anionic surfactant, a wide variety of cosmetic washing, hand-washing liquid, washing powder, complex soap, shampoo and detergent, phosphate-free detergents and other main raw material of choice.
3.Sodium C14-16 olefin sulfonate also has been used for hard surface detergent and personal care products, and is developing it in oil additives, starch processing aid, acrylate emulsion, mercerized cotton, wool washing, textile and paper wetting like applications in the field.
Alpha olefin sulfonates, primarily C1416, C1418, and C1618 blends, have been produced as low active solutions (<40%) for several decades.
Recent attention, however, has focused on producing AOS as concentrated pastes (70% – 75%) or as ultra-concentrated dry products (>90%).
The ultraconcentrated product is formed into needles, noodles, or flakes that may be packaged and sold as almost pure surfactant.
These forms can also be ground into a powder and admixed with other compounds using an agglomeration step to make a granular detergent formula
Feedstocks
The surfactant characteristics of sulfonated alpha olefins are influenced primarily by the carbon chain distributions of the starting feedstock.
The foaming properties, tolerance to water hardness, and detergency of the finished product can be controlled by adjusting the blending ratio of different alpha olefin cuts in the feed.

Commercial Production of AOS
The commercial production of alpha olefin sulfonates from alpha olefins is a multi-step process involving reacting the olefin with dilute SO3, digesting the crude sulfonic acid mixture, neutralizing with NaOH, and hydrolyzing the remaining sultones to product.
This process yields a mixture of 1, 2, 3,and 4-alkene sulfonates, 3-hydroxysulfonate, and 4-hydroxysulfonate.
The hydrolyzed product has traditionally been produced in the form of a 30% to 40% active matter solution, suitable for formulation into liquid products, or for use in conventional spray drying processes for low density detergent powders.
More recently, interest has been demonstrated in producing high active matter pastes, which can be stored and transported for significantly less cost.
High active matter pastes can be readily diluted for use in traditional liquid applications, and they can also be dried to produce an almost-pure surfactant in solid form.
AOS has a wide range of applications in the textile printing and dyeing industry, petroleum chemicals, and three oil extraction and industrial cleaning. AOS can be used as a concrete density modifier, foaming wall board, and fire fighting foam. It can also be used as a pesticide emulsifier, wetting agent, etc..

AIR ENTRAINERS
Air entrainment is the intentional creation of small air pockets in concrete by the addition of an air entraining agent to the mix.
The primary purpose of air entrainment is to increase the durability of the hardened concrete, especially in climates subject to freeze-thaw as the air pockets relieve internal pressure on the concrete by providing tiny chambers for freezing water to expand into.
Additionally, workability of the concrete is increased.
Based on our experience in surfactant chemistry, we offer a range of air entraining agents under the brand names Hostapur and, Genapol, and Zeliquid.
Our Hostapur OSB is used as an air entraining agent for mortars, plasters and grouts based on cement, gypsum or lime.
It is rapidly soluble, enables faster wetting of solid particles in the dry admixture and the build-up of micro foam in a short time.
The performance of this air entrainer is superior to traditional sodium lauryl sulfates, as it is not sensitive to calcium salts, non-hygroscopic and twice as efficient in producing controllable, strong and stable micro foam.
