AOS 92%：Sodium Alpha Olefin Sulfonate

AOS 92%: High-Performance, Eco-Friendly Anionic Surfactant for Demanding Applications

AOS 92% (Alpha Olefin Sulfonate) is a premium-grade anionic surfactant manufactured through an advanced gas-phase sulfonation process of alpha-olefins, resulting in a remarkably high active matter content of 92%. This high purity, combined with its superior performance profile and excellent environmental credentials, establishes AOS 92% as a versatile and effective ingredient for a wide spectrum of cleaning and personal care formulations.

Exceptional Cost-Effectiveness and Environmental Profile

AOS 92% offers an outstanding balance of performance and economic value. Its high activity level translates into greater formulating efficiency and cost-in-use. Furthermore, it is renowned for its favorable environmental footprint. AOS 92% demonstrates a biodegradation rate of >98%, readily meeting the stringent criteria for the EU Ecolabel. This makes it an ideal primary surfactant for phosphate-free detergents and other cleaning products designed with sustainability in mind.

Superior Performance in Hard Water

A key technical advantage of AOS 92% over traditional surfactants like Linear Alkylbenzene Sulfonate (LAS) is its exceptional stability and efficacy in hard water. The presence of high levels of calcium and magnesium ions, which typically diminish the foaming and cleaning power of many surfactants, has a minimal impact on AOS 92%. It maintains robust detergency and foam volume, ensuring consistent and reliable cleaning performance across regions with varying water hardness, without the need for high levels of chelating agents.

Broad Application Versatility

The combination of powerful cleaning, hard water tolerance, and mildness allows AOS 92% to be used across a diverse range of applications. It serves as a highly effective base surfactant in:

Laundry Detergents: Both powders and liquids, particularly where high foam and phosphate-free claims are desired.

Dishwashing Liquids: Provides excellent grease-cutting power and rich, stable foam.

Industrial & Institutional (I&I) Cleaners: For hard surface cleaning where reliable performance is critical.

Personal Care Products: Such as body washes and shampoos, where a balance of strong cleansing and mildness is required.
