MONSA® AOS-92

INCI name: Sodium Alpha-olefin Sulfonate

Alpha Olefin Sulphonate, or α-Olefin sulfonates, commonly called AOS for short, is a third-generation anionic surfactant. It's biodegradable, mild, and resistant to hard water, yet with outstanding detergency and excellent compatibility with other types of surfactant. MONSA® AOS-92 is widely used in the formulation of washing and person care products. It can enhance the cleaning efficiency of formula and produce rich foam, cooperating with other surfactant.

Benfits of MONSA AOS-92 alpha olefin sulfonate


Excellent Detergency:  AOS-92 is a highly effective cleaning agent that efficiently removes dirt, grease, and oils. This makes it a valuable

ingredient in dishwashing liquids, laundry detergents, and all-purpose cleaners.


Superior Foaming:  It produces rich and abundant foam, often desired by consumers as a sign of cleaning power. This is particularly beneficial

in shampoos, shower gels, and foaming hand soaps.


Biodegradable: Unlike some traditional surfactants, AOS-92 is readily biodegradable, minimizing its environmental impact. This is an

increasingly important factor for eco-conscious consumers and manufacturers.


Mildness:  Compared to some harsher surfactants, AOS-92 is considered milder on the skin. This makes it suitable for use in personal care

products like shampoos, body washes, and baby products, where gentle cleansing is crucial.


Wide pH Compatibility: It functions effectively across a broad pH range, offering formulators flexibility in creating products with various

acidic, neutral, or slightly alkaline properties.


Excellent Hard Water Resistance:  AOS-92 performs well even in hard water conditions where some surfactants become less effective. This

ensures consistent cleaning performance regardless of water mineral content.
