  • Applications

    Triethanolamine stearate (CAS 4568-28-9) is a versatile anionic surfactant and emulsifier used in cosmetics and personal care products such as shampoos, body washes, and facial cleansers to provide cleansing, foaming, and emulsion stability; it is also employed in household and industrial cleaning formulations as a surfactant and wetting agent to improve soil and pigment dispersion; in polymer and plastics processing it can function as a processing aid and emulsifier for latex and resin systems, helping stabilize emulsions and improve compatibility; in coatings and inks it serves as a surfactant and dispersant to enhance pigment dispersion, wetting, and rheology control; usage is subject to local regulations and formulation limits.
