Alpha Olefin Sulfonate (AOS) Liquid is a mild, high‑foaming anionic surfactant widely used in cosmetics for its excellent cleansing, emulsifying, and skin‑friendly properties. It serves as a sulfate‑free alternative to harsher surfactants like SLS and SLES, making it ideal for gentle formulations such as facial cleansers, shampoos, and body washes.

Technical Advantages
Anionic nature: The sulfonate group (−SO3−) gives strong detergency and emulsification power.
Superior pH stability: AOS remains effective in both acidic and alkaline formulations, unlike sulfates that degrade in low pH.
Excellent hard‑water tolerance: Performs well even in the presence of calcium and magnesium ions.
Enhanced mildness: Causes less protein denaturation, reducing skin and eye irritation compared to SLS/SLES.
Biodegradability: Environmentally friendly and aligns with eco‑conscious cosmetic trends.
Formulation Notes
Typical usage level: 5–30 % depending on product type and desired foam intensity.
Compatibility: Works well with non‑ionic and amphoteric surfactants (e.g., Cocamidopropyl Betaine) to improve mildness and viscosity.
pH range: Stable between pH 5–9, suitable for most skin‑care and hair‑care formulations.
Appearance: Clear to pale yellow viscous liquid, easily soluble in water.
