  • Product Details

Sodium α-alkenyl sulfonate (CAS Nr.: 68439-57-6) AOS 92% Powder and AOS 35% liquid is an anionic surfactant with high foaming and good hydrolytic stability. It has excellent resistance to hard water, low toxicity, mildness, low irritation and good biodegradability. Especially used in non-phosphorus detergents.


Surface activity

AOS and other anionic surfactants (such as LAS, AS, AES, etc.) also have excellent surface activity. Within a certain concentration range, AOS can reduce the surface tension of water from 72mN.m-1 to 30-40mN.m- 1 or so. The critical micelle concentration (cmc) of several anionic surfactants measured by surface tension method at 25°C is as follows:
