Description

Butanedioic Acid, Sulfo-, Mono (C16-18 And C18-Unsatd. Alkyl) Esters, Ammonium Sodium Salts is a high-performance anionic surfactant derived from succinic acid, valued for its excellent emulsifying, dispersing, and wetting properties. This compound is particularly significant for its ability to function effectively under a wide range of conditions, including hard water and high electrolyte environments. It is a critical ingredient for formulators in the personal care, industrial cleaning, and textile processing industries seeking mild yet powerful surface-active agents.

Application

• Personal Care & Cosmetics: Acts as a primary or secondary surfactant in shampoos, body washes, and facial cleansers, providing rich lather and mild cleansing suitable for sensitive skin.
• Industrial & Institutional (I&I) Cleaners: Used in hard surface cleaners, degreasers, and alkaline formulations where stability and soil suspension are required.
• Textile Processing: Serves as an effective wetting agent, emulsifier, and dispersant in dyeing and finishing baths to ensure uniform color application.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide sprays to enhance spreading and adhesion on plant surfaces.
• Emulsion Polymerization: Functions as a surfactant in the production of synthetic latexes for paints, coatings, and adhesives.
• Metal Working Fluids: Provides emulsification and lubrication in coolants and drawing compounds.
