What is α-Olefin Sulfonate?
AOS is an anionic surfactant produced by sulfonation of alpha-olefins, followed by neutralization and hydrolysis. It offers a balance of high detergency, foam stability, and environmental compatibility.
Core Performance Advantages
- Excellent Detergency: AOS delivers strong oil and dirt removal, making it ideal for both household and industrial cleaning.
- Superior Foaming Power: Produces abundant, stable foam, even in low concentrations.
- Hard Water Resistance: Maintains performance in high-mineral water conditions, reducing formulation complexity.
- High Biodegradability: Eco-friendly profile with rapid biodegradation, supporting green product development.
- Mildness vs Traditional Anionics: Less irritating than some traditional surfactants, suitable for personal care formulations.
What is α-Olefin Sulfonate Used for?
- Household Cleaning: Personal care products such as shampoos, body washes, hand soaps, facial cleansers, etc.
- Industrial Applications: Building material enhancers, industrial detergents, etc.
- Textile Printing and Dyeing: Used as cleaning agents, scouring agents, and dyeing auxiliaries.
- Petroleum Industry: Used as surfactants for enhanced oil recovery (tertiary oil recovery).
