Description

Sodium Butyl 9(Or 10)-(Sulphonatooxy)Octadecanoate is a specialized anionic surfactant derived from octadecanoic acid, modified with a sulphonatooxy group and esterified with butanol. This unique molecular structure provides excellent emulsifying, wetting, and dispersing properties, making it a valuable functional additive in demanding formulations. It is primarily utilized by manufacturers in the personal care, industrial cleaning, and textile processing industries seeking high-performance surface-active agents.

Application

• Personal Care Formulations: Acts as an effective emulsifier and solubilizer in creams, lotions, and hair care products.
• Industrial & Institutional (I&I) Cleaners: Serves as a key wetting and dispersing agent in heavy-duty degreasers and alkaline cleaners.
• Textile Processing: Used as a scouring agent, lubricant, and dyeing assistant to improve fiber wetting and dye penetration.
• Agricultural Adjuvants: Enhances the spreading and sticking of pesticides and herbicides on plant surfaces.
• Emulsion Polymerization: Functions as a surfactant in the production of synthetic latexes and polymer dispersions.
• Metal Working Fluids: Provides emulsification and surface activity in coolants and drawing compounds.
