  • Applications

    Monoethanolamine lauryl sulfate (CAS 4722-98-9) is an anionic surfactant used primarily as a wetting agent and emulsifier in detergent and personal care formulations; it is also employed as a wetting and emulsifying agent in paints, coatings, and inks to improve flow and dispersion; in the textile and materials processing sector it serves to enhance wetting and dispersion of dyes and other formulation components; additionally, it can be used as an intermediate for synthesizing other surfactants and as a practical additive in industrial emulsions to improve foaming and stabilization.
