  • Applications

    Laureth-1 phosphate is an anionic surfactant commonly used as an emulsifier and wetting agent in cosmetic and personal care formulations, helping to stabilize emulsions and improve the uniformity of products such as shampoos, cleansers, and skin care items. It is also employed in household cleaning products and industrial cleaners to enhance soil dispersion and cleaning performance. In industrial manufacturing, it serves as a dispersing and surface-active additive in coatings and inks, promoting pigment dispersion and better substrate wetting. In polymer processing, it can act as an emulsifier or processing aid to stabilize latexes and emulsions. In agriculture, Laureth-1 phosphate may be used as an emulsifier or deposition-enhancing additive in formulations of crop protection products and herbicides to improve coverage and efficiency.
