Sodium Alpha Olefin Sulphonate (Sodium Alpha Olefin Sulfonate)

Quick Links

Synonym: Sodium C14-16 olefin sulfonate, AOS

A mixture of long chain sulphonate salts from the sulphonation of C14-16 alpha olefins. Consists of sodium alkene sulphonate and sodium hydroxyalkane sulphonates.

Key Properties

Are more soluble than the dodecylbenzenesulphonates and alky sulphates due to the hydroxy group and the presence of unsaturated links in alkenyl derivatives
Good chemical stability can be used in strong acid or alkaline formulations
Give excellent cleaning and foaming in hard water
Foams well in the presence of sebum
Good foam stability

Applications

Liquid hand soap
Foaming agent for personal care
Detergent for household and toiletries
Emulsion polymerisation
Shampoos - will not strip the hair of natural oils. When used in combination with betaines (Amphokem CAB) or amine oxides (Lansurf CAO) a similar performance to an alkyl sulphate (Kemsurf DSA) can be achieved
Liquid dishwashing
Firefighting foams
