Product Introduction

This anionic surfactant (AOS) offers excellent detergency, rich and stable foam, and strong emulsifying power. It dissolves readily in water, disperses lime soap effectively, and resists hard water. It is biodegradable, skin-friendly, and highly compatible with other ingredients. Formulations containing AOS produce fine, dense foam, feel pleasant, and rinse easily across a wide pH range. It is widely used in laundry detergent, compound soap, dishwashing detergent, and phosphate-free detergents, as well as in personal care products such as shampoo, body wash, and facial cleanser. AOS also sees broad use in oil fields, mining, firefighting, construction, and textile printing and dyeing.
