  • Applications

    Sodium lauroyl methyl taurate (CAS number: 4337-75-1) is a mild surfactant used in cosmetics and personal care as a cleansing and conditioning agent in products such as shampoos, facial cleansers, and body washes, while also contributing to skin and hair softness; it is employed in household cleaning products like dish liquids and all-purpose cleaners as a surfactant and foaming agent; in industrial manufacturing it acts as an emulsifier and dispersant in formulations, helping stabilize emulsions and improve wetting in coatings and inks; it may be evaluated as an excipient or solubilizer in pharmaceutical formulations; and it is considered as a surfactant additive for polymer and plastic processing or surface treatment applications.
