  • Applications

    Myristyl trisiloxane (286938-65-6) is a silicone-based additive used across several industries; in cosmetics and personal care it can function as an emollient and conditioning agent, providing slip and a smooth feel. In coatings and inks it may act as a surface-modifying additive to improve wetting, leveling and water repellency. In polymers and plastics processing it can serve as a processing aid or slip/release agent, aiding mold release and reducing friction during mixing and shaping. In industrial manufacturing it may be used as an intermediate or precursor in silicone polymer syntheses, or as a compatible formulation additive. In cleaning and polishing formulations it may be employed to enhance gloss and lubricity, subject to formulation limits.
