  • Applications

    2,4,7,9-Tetramethyl-5-decyne-4,7-diol ethoxylate (CAS 9014-85-1) is a nonionic, ethoxylated surfactant used as a versatile wetting, emulsifying, and dispersing agent across multiple industries. In coatings and inks, it improves pigment wetting, leveling, and emulsion stability. In cleaners and household products, it acts as a surfactant and solubilizer to enhance soil removal and formulation stability. In polymer and plastics processing, it serves as a processing aid and stabilizer for latex formulations and polymer emulsions. In cosmetics and personal care, it can function as a mild surfactant and emulsifier. In agriculture, it may be employed as an adjuvant to improve spray coverage and penetration. Use is subject to local regulations and formulation limits.
