Description

Potassium Octadecyl Sulphate is a high-purity anionic surfactant derived from stearyl alcohol. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in aqueous systems. It is a critical raw material for formulators in the personal care, agrochemical, and industrial cleaning sectors who require a stable, high-performance surfactant with potassium counter-ion benefits.

Application

• Personal Care & Cosmetics: Acts as a primary surfactant and emulsifier in shampoos, body washes, and liquid soaps, providing rich lather and mild cleansing.
• Agrochemical Formulations: Used as a wetting agent and dispersant in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Industrial & Institutional (I&I) Cleaners: Serves as a key ingredient in hard surface cleaners, degreasers, and textile processing aids for its superior detergency.
• Emulsion Polymerization: Functions as an effective emulsifier in the production of synthetic latexes, such as styrene-butadiene and acrylic polymers.
• Textile & Leather Processing: Employed as a levelling agent, softener, and dyeing assistant to ensure uniform processing and finish.
• Research & Development: Utilized as a standard or reagent in chemical synthesis and surface science studies.
