Description

Sodium 9-(Sulphooxy)Octadecanoate is a specialized anionic surfactant derived from stearic acid, featuring a sulfated ester group. This unique molecular structure provides excellent emulsifying, wetting, and dispersing properties in challenging formulations. It is a critical intermediate and functional additive for manufacturers in the personal care, industrial cleaning, and textile processing sectors seeking enhanced performance and stability.

Application

• Personal Care Formulations: Acts as a primary emulsifier and surfactant in creams, lotions, and hair care products for stable oil-in-water emulsions.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaning formulations, and alkaline cleaners for its superior wetting and soil penetration.
• Textile Auxiliaries: Serves as a scouring agent, lubricant, and finishing aid in fiber and fabric processing to improve handle and dye uptake.
• Emulsion Polymerization: Functions as an effective emulsifier and stabilizer in the production of synthetic latexes, such as acrylics and styrene-butadiene rubber (SBR).
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spreading, adhesion, and overall efficacy on plant surfaces.
• Leather Processing: Employed in fatliquoring and dyeing processes to ensure even penetration and softness of the finished leather.
