ALPHA OLEFIN SULPHONATE

Ionic surfactants which contain hydrophobic hydrocarbon group connected with one or several hydrophilic groups dissociate into a positively charged cation and a negatively charged anion in an aqueous solution. If the head is negatively charged to carry the surface active properties, it is called anionic surfactant, whereas a positively charged head is the carrier of the surface active properties in cationic surfactants. Typically cationic surfactants are based on the nitrogen atom carrying the cationic charge such as amine and quaternary ammonium product.

Cationic surfactant is considered to be poor cleaners but it contributes to the fabric softening, the disinfecting properties, and the grease-water interfacial tension reducing. Cationic surfactants include quaternary ammonium compounds, amines (primary, secondary, tertiary, diamines, polyamines, amine salts), imidazoline compounds, betaine compounds, and esterquats.

Anionic surfactant is the widely used type of surface active agent for laundry detergents, liquid cleaners and shampoos due to excellent cleaning properties particularly effective at oily soil cleaning and oil/clay soil suspension. Anionic surfactants are deactivated in many hard water. To prevent deactivation, builders should be dosed. Anionic surfactant is used as a emulsifier in cosmetics, tooth paste, cream, shampoo, and acrylic binder. Common soap is an anionic surfactant. Carboxylate, sulfate, sulfonate and phosphate are the polar groups in anionic surfactants. Anionic surfactants include alkyl benzene sulfonate, fatty acid salts, sodium lauryl sulfate, alkyl sulfate salts, sodium lauryl ether sulfate, alpha-olefin sulfonates, phosphate esters, sulphosuccinates, alkyl phenol ether sulfates, and isethionates.

 

Sodium Alpha Olefin Sulfonate is used as a foaming agent combining cleaning activity for liquid soaps, washing compounds and liquid detergents. It provides acid resistance and biodegrability. It is used in emulsion polymerization.

Mild anionic, high-foaming & well-emulsifying surfactant. Water-soluble, pH: 8 (10% solution), 40% active substances. Yellowish liquid, slightly viscous, faint odor.

 

Non-sulfate anionic surfactants are often used in cleansing products for personal care, hard surfaces, laundry and industrial applications. In personal care alone, they range in variety; although notably, cleansers with added hair color-retention benefits and formulas positioned for the hair, scalp and body represent the segments in highest demand. Due to these broad product applications, customizable performance attributes and biodegra­dability, the use of alpha olefin sulfonate (AOS) surfactants has increased dramatically.

 

The most common Alpha Olefin Sulphonate used in personal care is sodium C14-16 olefin sulfonate, which functions as a detergent, wetting agent and emulsifier depending on the application.18 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.

 

In addition, the surfactant maintains performance at alkaline and acidic ranges, allowing flexibility for formulators. This stability is attributed to the sulfonate groups covalently bonded to a carbon; conversely, sulfate-based surfactants tend to hydrolyze below pH 4 due to inorganic ester bonds that cleave and yield a sulfate anion and an alcohol. The pH stability of C14-16 olefin sulfonate has generated additional interest over lauryl sulfates and lauryl ether sulfates for both claims and performance. It also allows the material to be provided as a preservative-free aqueous solution, using excess alkalinity for preservation.

At the time of the original safety assessment, it was reported by industry that sodium olefin sulfonates, in general, were used up to 5% in cleansers and 16% in shampoos and bath and shower products.  Specifically, in 1995, it was reported by the Cosmetic, Toiletries, and Fragrance Association that sodium C14-16 olefin sulfonates was used at 3.6% in facial cleansing foams, > %5 – 10% in skin care preparations, and > 10% in personal cleanliness products. There were no concentrations of use reported uses for sodium C12-14 olefin sulfonate, sodium C14-18 olefin sulfonate, or sodium C16-18

olefin sulfonate in the original safety assessment. In 2013, data on ingredient usage are provided to the Food and Drug Administration (FDA) Voluntary Cosmetic Registration Program. A survey was conducted by the Personal Care Products Council (Council) of the maximum use concentrations for these ingredients also in 2013. Sodium C14-16 olefin sulfonate was reported to be used in 11 leave-on products, 247 rinse-off products, and 42 products that are diluted for bath.  These include 6 baby products, 36 hair products, 1 lipstick, and 171 personal cleanliness products. Sodium C14-16 olefin sulfonate was reported to be used up to 13.2% in leave-on products, 19% in rinse-off products, and 10% in bath products. These include up to 10% in bubble baths and bath soaps and detergents, 19% in shampoos, and 13.2% in other personal cleanliness products. There were no concentrations of use reported for any baby products. Sodium C14-18 olefin sulfonate was reported to be used in 5 shampoos.  Sodium C14-18 olefin sulfonate is used up to16% in shampoos. According to the VCRP, there were no reported uses for sodium C12-14 olefin sulfonate. The Council reported that sodium C12-14 olefin sulfonate is used up to 5% in rinse-off products, including shampoos, hair tints, and skin cleansing preparations. There were no frequencies or concentrations of use reported for sodium C16-18 olefin sulfonate.
