Description

Sodium 1-Octadecyl Sulphonatoacetate is a high-purity anionic surfactant derived from stearyl alcohol. This compound is valued for its excellent emulsifying, dispersing, and wetting properties, making it a versatile performance additive. It is primarily sought after by formulators in the personal care, textile processing, and industrial cleaning sectors who require a mild yet effective surfactant with good compatibility in various systems.

Application

• Personal Care Formulations: Acts as a primary or secondary surfactant in shampoos, body washes, and facial cleansers for its mildness and rich lather.
• Textile Auxiliaries: Used as a wetting agent, emulsifier, and dispersant in dyeing and finishing processes to ensure even color distribution.
• Industrial & Institutional (I&I) Cleaners: Serves as a key component in heavy-duty degreasers, metal cleaners, and floor care products for its effective soil removal.
• Emulsion Polymerization: Functions as an emulsifier in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Agricultural Formulations: Employed as a dispersant and wetting agent in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Leather Processing: Used in soaking, degreasing, and dyeing stages to improve penetration and uniformity of chemicals.
