Product Category: Anionics
Sodium Alpha Olefin Sulphonate (Sodium Alpha Olefin Sulfonate)
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
