AOS 92% Powder Alpha-Olefin Sulfonate, High Active Anionic Surfactant

Alpha-Olefin Sulfonate (AOS 92% Powder) is high-activity powder-form anionic surfactant produced by advanced sulfonation, neutralization and spray-drying process. It generates rich, stable and long-lasting foam even under hard-water and low-temperature conditions, with outstanding detergency, wetting and emulsifying capacity.

Compared with conventional anionic surfactants, AOS 92% Powder features low skin irritation and readily biodegradable property. It shows excellent compatibility with non-ionic, amphoteric as well as other anionic surfactants, bringing great flexibility for detergent formula development. Strict in-house quality control guarantees stable batch-to-batch quality and low impurity level.

It is widely applied in detergent powder, soap base, phosphate-free cleaning powder, hand-washing powder. It also fits textile scouring agents, oilfield foaming agents, fire-fighting foam additives and other industrial foaming systems. Free samples can be provided for your lab formulation test.

Solutions

AOS 92% Powder is a multi-purpose powdery surfactant for household and industrial sectors. Below are the application references with suggested dosage.

Household Detergent Powder

Products: Laundry powder, hand wash powder, phosphate-free cleaning powder Features: High foam and hard-water resistance, improves washing performance of powder formulas Recommended dosage: 3%–12%

Personal-Care Powder Products

Products: Bath powder, cleansing powder Features: Low irritation, rich foam, good compatibility with amphoteric surfactants Recommended dosage: 4%–10%

Industrial & Special Application

Products: Textile scouring powder, oil-field foaming agent additive, fire-fighting foam raw material Features: Stable foaming performance under high-temperature and high-electrolyte environments Recommended dosage: 2%–15%, adjust according to practical working conditions

What Problems Does It Solve?

For formulators, AOS 92% Powder solves three major formulation pain points: unstable foam under hard-water conditions, high skin irritation of cleaning products, and poor compatibility when blended with other surfactants. It is widely applied in household powder detergents, personal-care powder products, textile processing and oilfield foaming industries.

What Makes It Stand Out?

Different from 35% liquid AOS, AOS 92% Powder has ultra-high active content. It cuts logistics costs for long-distance shipments. It maintains stable creamy foam under low-temperature and high-hard-water conditions. Featuring low skin irritation and readily biodegradable properties, it blends perfectly with LABSA, AES, betaine and non-ionic surfactants to optimize the cost-performance ratio of finished products.
