Alpha olefin sulphonate (AOS) is the sodium salt of alpha-olefin sulphonate (SAOS), commonly known as AOS. It has excellent properties in wetting, blending, emulsification, solubility, good stability at high temperatures, and detergency. It has high foaming characteristics, mildness, less resistance to hard water, and is excellent bio-degradable. These surfactants provide outstanding detergency, high compatibility with hard water, and good wetting and foaming properties. AOS is free of skin irritants and sensitizers, and it biodegrades rapidly.
