  • Applications

    Myristoyl lactylic acid (CAS 18696-55-4) is commonly used as an emulsifier and surfactant in formulation chemistry, helping stabilize oil-in-water systems and influence texture in a range of products; in cosmetics and personal care, it functions as an emollient-compatible emulsifier and stabilizer in creams, lotions, and color cosmetics. In the food processing sector, it is evaluated as an emulsifier and stabilizer to improve crumb structure and product stability in baked goods and dairy-based formulations. It also serves as a processing aid, lubricant, or plasticizer in polymer and coating formulations, aiding pigment dispersion and film formation. In pharmaceutical applications, it may act as an excipient or solubilizer in drug formulations under appropriate regulatory control. Additionally, it can appear as a surfactant or emulsifier in household cleaning products, contributing to formulation performance.
