Description

(2-Hydroxyethyl)Ammonium Decyl Sulphate is a specialized anionic surfactant derived from decyl alcohol and sulfated with a 2-hydroxyethylammonium counterion. This compound is valued for its excellent wetting, emulsifying, and foaming properties, particularly in formulations requiring mildness and good solubility. It is primarily utilized by manufacturers in the personal care, household & industrial cleaning, and textile processing industries to enhance product performance and stability.

Application

• Personal Care Formulations: Acts as a primary or secondary surfactant in mild shampoos, body washes, facial cleansers, and shaving foams.
• Household & Industrial Cleaners: Used in liquid dishwashing detergents, all-purpose cleaners, and hard surface cleaners for effective grease removal and foam generation.
• Textile Processing: Serves as a wetting agent, emulsifier, and dye leveling assistant in fabric pretreatment and dyeing baths.
• Emulsion Polymerization: Functions as an emulsifier in the production of latex polymers for paints, coatings, and adhesives.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to improve spray coverage and penetration on plant surfaces.
• Metal Working Fluids: Used as an emulsifier and corrosion inhibitor in coolants and cutting fluids.
