Description

Sodium Octadecadienyl Sulphate is a high-purity anionic surfactant derived from octadecadienol. This compound is valued for its excellent emulsifying, wetting, and foaming properties in demanding industrial formulations. It is a critical raw material for manufacturers in the personal care, textile processing, and specialty chemical industries seeking reliable performance and consistent quality.

Application

• Primary Surfactant in Personal Care: Used in shampoos, body washes, and facial cleansers for its rich lather and mild cleansing action.
• Textile Processing Aid: Functions as an effective wetting and scouring agent in the pretreatment and dyeing of natural and synthetic fibers.
• Industrial Emulsifier: Employed in the formulation of polymer emulsions, agrochemicals, and leather processing chemicals.
• Enhanced Oil Recovery (EOR): Investigated for use in chemical flooding formulations to reduce interfacial tension in reservoir conditions.
• Household & Institutional Cleaners: Provides effective surface wetting and soil suspension in liquid dish soaps and hard surface cleaners.
