Sodium C14-16 Alpha Olefin Sulfonate AOS CAS 68439-57-6 Anionic Surfactant Low Skin Irritation

Sodium C14-16 Olefin Sulfonate (AOS) is prepared via sulfonation neutralization. It appears as a white to yellow powder, primarily composed of olefin sulfonate and a small amount of disulfonate. This substance exhibits excellent biodegradability, low irritation, and low toxicity.

Sodium C14-16 Olefin Sulfonate is widely used in the production of foam-based skincare detergents, demonstrating high stability in oily environments, strong detergency, and low skin irritation. In heavy oil extraction applications, when combined with sodium carbonate as a viscosity reducer, Sodium C14-16 Olefin Sulfonate shows remarkable performance in reducing emulsion viscosity.

• Excellent biodegradability
• Effective in removing dirt in hard water
• Good foaming properties with low skin irritation
• Wide applicable pH range, widely used as a basic ingredient in shampoos

Packaging: Industrial-grade solid AOS is typically packaged in 25 kg bags (woven bags or kraft paper bags lined with plastic film), with some suppliers offering ton bags (e.g., 1000 kg). Liquid AOS is usually packaged in 200 kg plastic drums.

Storage Requirements: Store in a cool, ventilated, dry, and sealed place, protected from moisture and clumping. Avoid storing with strong acids or strong oxidizers.

Transportation: Transported as a non-hazardous chemical by road/rail as ordinary chemicals. Requires protection from rain and direct sunlight. For export or bulk shipments, containerized bulk shipping or palletized wrapping can be used.

• Laundry Detergent: Used in low-phosphate or phosphate-free detergents with excellent synergistic effects with enzymes. Provides superior cleaning performance for sebum, oily, and powdery dirt.
• Soap Production: Enhances foaming power, increases resistance to hard water, improves flexibility, and reduces cracking in soap formulations.
• Liquid Detergents: Widely used due to excellent detergency, hard water resistance, and viscosity characteristics. Offers low irritation and good biodegradability.

• Widely used in shower gels, shampoos, hand soaps, and soap-based formulations
• Extremely stable under acidic conditions, ideal for skin care products
• Exhibits rapid foaming, rich and delicate foam, and easy rinsing properties
• Excellent compatibility with other personal care ingredients

• Excellent surface activity, reducing water surface tension for improved wetting and penetration
• Acts as wetting agent and emulsifier for better dye penetration and uniformity
• Enhances dye solubility and dispersibility for improved dyeing effects
• Significant hard water resistance and good biodegradability

Used in tertiary oil recovery to reduce oil-water interfacial tension and promote crude oil flow. When combined with heavy alkylbenzene sulfonates, achieves ultra-low interfacial tension and can increase oil recovery by approximately 20%.

• Starch processing aid
• Acrylic ester emulsion polymerization surfactant
• Mercerization of cotton and wool washing
• Wetting agent in papermaking
• Concrete density improver, foamed wall panels, fire-fighting foaming agents
• Pesticide emulsifier and wetting agent
