Alpha Olefin Sulfonate (AOS)
Alpha Olefin Sulfonate (AOS) is an anionic surfactant derived from the sulfonation of alpha olefins, typically sourced from natural or synthetic fatty alcohols. It is commonly used in personal care formulations to provide effective cleansing and foaming. Known for its high flash foam and excellent rinsability, AOS is frequently included in shampoos, body washes, facial cleansers, and other rinse-off systems.
It is often selected as an alternative to traditional sulfates in sulfate-free formulations due to its strong performance and broad compatibility with other surfactants.

Used in a new facial cleanser and the lather is rich and long-lasting. It rinses clean without leaving any residue. Works well with other ingredients in the formula. Satisfies the need for a strong cleanser without being harsh on the skin.
Warren James –
Great performance in a body wash. The foam builds quickly and cleans thoroughly. I noticed no irritation after several weeks of use. Works well in a sulfate-free blend.
Cameron McDonald –
The foaming ability is excellent, and it cleans effectively. A bit more expensive than some alternatives, but the performance justifies the cost in a daily-use product.
Felicity MacLeod –
In a shampoo formulation, it delivers strong lather and leaves hair feeling clean and soft. No greasiness or residue after washing. Very reliable in daily use.
Charles Edmunds –
Works well in combination with other surfactants. The rinsability is outstanding, and the product feels balanced on the skin. Slight improvement in texture could be made, but overall very effective.
