Olefin Sulfonate (also: alpha-olefin sulfonates or AOS) are a group of anionic surfactants, which are used as detergents.
The compounds contain a - mostly linear, primary - alkyl R and a monovalent cation M, preferably sodium.
The most frequently used example of this group of substances is Olefin Sulfonate.
Olefin Sulfonate is a mixture of long chain sulfonate salts prepared bysulfonation of C14-16 alpha olefins.
Olefin Sulfonate consists chiefly of sodium alkene sulfonates and sodiumhydroxyalkane sulfonates.
Olefin Sulfonate is commonly used in hair, skin, and other personal care cleansing formulations.
We can also find them in household cleansing products.
Olefin Sulfonate is a good example often used in shampoos and other cleansing products.
Olefin Sulfonate is an anionic surfactant.
Olefin Sulfonate is used as a primary surfactant or mixed with other cleansing agents working to boost the overall detergency of the formulation.
Being a Olefin Sulfonate, it is keenly sought for its sulfate-free formulation.
Olefin Sulfonate is a different anion; it is not sulfate and thus has very different physical and chemical properties.
The chemical structures highlight the basic difference between sulfate and sulfonate groups.
Although both are anionic and carry negative charge density, the different nature of chemical bonding makes them completely different molecules.
Usage of Olefin Sulfonate
Olefin Sulfonate 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 typically used 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.
Olefin Sulfonate is being introduced in some shampoos as an alternative to sodium laureth sulfate.
Some groups and sellers suggest that it is better for someones health, but this claim lacks evidence.
Olefin Sulfonate is a formaldehyde free solution of sodium C14-C16 Olefin sulfonate preserved with MCI/MI.
Olefin Sulfonate can be used in variety of applications due to its excellent viscosity, hard water stability, detergency, foam characteristics, and pH stability over a broad pH range.
Olefin Sulfonate is a milder surfactant compared to lauryl sulfates and is used in high performing sulfate-free, shampoos, body wash, hand soap and pet care formulations.
Olefin Sulfonate is highly effective in unloading undesirable liquids and particulates from gas producing wells and exhibits exceptional thermal stability up to 400° F.
Olefin Sulfonate is readily biodegradable.

Olefin sulfonate is a mild anionic surfactant with excellent viscosity and foam characteristics.
Olefin sulfonate offers good solubility in water, high surface activity, enhanced detergency and foamability, compatability with all other types of surfactants, low sensitivity to water hardness, high level of biodegradability and low irritation and ecotoxicity.
Olefin sulfonate is an optimal surfactant solution for the formulation of personal care and cosmetic products, HI&I cleaning and laundry detergents.
For its unique properties the product is also used in agricultural products, construction industry, fire-fighting foams etc.
Olefin sulfonate and enzymes have better solubility.
The activity of residual enzymes in detergent solutions containing domestic proteinases and imported proteinases(such as Savnase) was compared.
Over time, the residual enzyme activity of anionic active groups divided into pure LAS was low.
The residual enzyme activity is higher in detergent solution with Olefin sulfonate partial replacement or all substitution of LAS.
Olefin sulfonate Application of Soap
Soap produces insoluble saponin in hard water, affecting the decontamination effect.
Adding Olefin sulfonate can increase the solubility of soap in water, and the wettability and foam power of soap liquid at low temperatures also increase rapidly.
Olefin sulfonate is added to soaps with sodium adipose as the main ingredient.
The various characteristics of soaps are improved, foaming force is enhanced, hard water resistance is improved, flexibility is enhanced, and cracking is not easy.
Liquid Detergents Application of Olefin sulfonate
Due to the large irritation of LAS, many washing products no longer use LAS as an active component, while Olefin sulfonate has low irritation and good biodegradability, making it a more suitable alternative.
In liquid detergents, Olefin sulfonate has a greater influence on the viscosity of the product.
The viscosity is improved with the commonly used fatty alcohol diethanolamide and Na-Cl.
The effect is not ideal.
The use of fatty alcohol monoethanolamide, amine oxide, betaine and NH4Cl can play a good adhesion role.
Due to the characteristics of Olefin sulfonate in decontamination, hard water resistance, viscosity, etc.,
Olefin sulfonate has a wide range of applications in liquid detergents with high active components.
Olefin Sulfonate Application of personal care supplies
Olefin sulfonate is as mild as AES, and LAS and AS are much larger than Olefin sulfonate.
Therefore, Olefin sulfonate has a wide range of uses in personal care products.
Olefin sulfonate is extremely stable under acidic conditions.
Normal human skin is weakly acidic(pH is about 5.5) and is suitable for using Olefin sulfonate as a component of personal cleaning products.
The shampoo with Olefin sulfonate as the main active component is better than that with K12.
Renso reported that the foam released by Olefin sulfonate was full of cream and felt like soap when washed.
This characteristic is suitable for the washing habits of Chinese people.
Therefore, Olefin sulfonate can be used in personal care products such as bath fluids, hand sanitizer and cleansing milk.
Other Olefin Sulfonate Application
Olefin sulfonate has a wide range of applications in the textile printing and dyeing industry, petroleum chemicals, and three oil extraction and industrial cleaning.
Olefin sulfonate can be used as a concrete density modifier, foaming wall board, and fire fighting foam.
Olefin sulfonate can also be used as a pesticide emulsifier, wetting agent, etc..
Olefin sulfonate is a pale yellow 40% aqueous solution of sodium C14-16 alpha olefin sulfonate.
Olefin sulfonate combines the advantages of high foaming power, good emulsification, mildness to the skin, and excellent lime soap dispersion to give the formulator maximum flexibility in the preparation of light and heavy-duty cleaners.
Olefin sulfonate is also suitable for use in acidic formulations such as those containing alpha hydroxyl acids or salicylic acid.
Olefin sulfonate is perfect for sulfate-free personal care and detergent products.
