In Alpha Hydroxy Acid and Beta Hydroxy Acid (AHA/BHA) systems, pH is intentionally low (typically 3.5–4.5) to keep acids active. Many surfactants lose stability, thin out, or hydrolyze under acidic conditions. Alpha Olefin Sulfonates (AOS) excel in these formulations where others fail.

Pilot Chemical offers many grades of AOS, including the first-to-market biobased AOS, CalCare™ AOS-40 HP (Sodium C14-16 Olefin Sulfonate) surfactant. AOS has the following key features and benefits:

Foaming and Cleansing Properties

Delivers rich lather and cleanses while being mild in personal care products.

 

Stability and Thickening

Remains stable across broad pH levels and thickens formulations easily with sodium chloride.

 

Sustainability

Transitioning AOS production from petroleum to biobased olefins offers a new grade that advances sustainability goals.

 

Versatility

AOS is used in many personal care applications including AHA/BHA facial cleansers, shampoos, body wash, and hand soap.
