Description

Sodium 9-Octadecenyl Sulphate is an anionic surfactant derived from oleic acid, valued for its excellent emulsifying, wetting, and dispersing properties. This compound is particularly significant for its ability to reduce surface tension effectively in aqueous systems, making it a versatile processing aid. It is primarily needed by manufacturers in the personal care, textile, agrochemical, and industrial cleaning sectors for formulating stable emulsions and enhancing product performance.

Application

• Personal Care & Cosmetics: Acts as a primary surfactant and emulsifier in shampoos, body washes, and facial cleansers for rich lather and mild cleansing.
• Textile Processing: Used as a wetting agent and emulsifier in scouring, dyeing, and finishing baths to ensure even dye penetration and fiber treatment.
• Agrochemical Formulations: Serves as an effective emulsifier and dispersant in pesticide and herbicide concentrates for stable spray solutions.
• Industrial & Institutional (I&I) Cleaners: Functions as a key component in heavy-duty degreasers, metal cleaners, and floor care products.
• Emulsion Polymerization: Employed as a surfactant in the production of synthetic latexes for paints, coatings, and adhesives.
• Leather Processing: Utilized in tanning and fatliquoring processes to aid in the even distribution of oils and chemicals.
