  • Applications

    Sodium Tetradecyl Sulfate is an anionic surfactant used as a versatile wetting, emulsifying and foaming agent across multiple sectors; in cosmetics and personal care it functions as a surfactant and cleanser in shampoos and cleansers; in household products it supports effective cleaning and formulation stability; in industrial manufacturing it serves as a surfactant and emulsifier to stabilize emulsions, improve wetting and disperse solid pigments or fillers; in polymers and plastics processing it acts as an emulsifier or dispersant during latex and polymer formulations; in coatings and inks it improves wetting, pigment dispersion and leveling; in agriculture it may be used as an adjuvant or formulation additive to enhance dispersion of active ingredients.
