CAS Number:
68439-57-6
Chemical Classification:
Anionic Surfactant (Alpha Olefin Sulfonate)
INCI Name:
Sodium C14-16 Olefin Sulfonate
Description:
AOS 92%Powder is a high-concentration, free-flowing powder form of the anionic surfactant Sodium Alpha Olefin Sulfonate. It is primarily used in solid formulations and applications where a high-active, low-moisture surfactant is required
Uses:
Its high concentration and powder form make it suitable for solid and concentrated formulations.
· Solid Detergents & Soap Bars: A primary active ingredient in laundry powders, synthetic detergent (syndet) bars, and scouring powders.
· Personal Care: Used in solid shampoos, waterless beauty products (shampoo bars, cleansing sticks), and facial cleansers.
· Industrial Applications: Used in construction as an air-entraining agent for concrete, in firefighting foams, and in oil field chemicals.
Origin:
It is a semi-synthetic anionic surfactant. It is produced through the sulfonation of C14-C16 alpha-olefins (often derived from coconut or palm oil), followed by neutralization and drying into a powder.
What does AOS 92% Powder do in a formulation?
Its primary functions are:
- Cleansing
- Foaming
- Surfactant
Safety Profile:
· Handling: Handle in a well-ventilated area as the fine powder can become airborne easily. For external use only.
· Skin Compatibility: Recognized for good biodegradability and lower skin irritation compared to some sulfates like Sodium Lauryl Sulfate, but is still considered a strong cleanser.
· Storage: Store in a cool, dry place in sealed containers to avoid moisture absorption.
