  • Applications

    Tripotassium ursolyl phosphate (CAS number: 950170-99-7) is used primarily as an ionic surfactant and dispersant in a range of formulations, helping stabilize pigment suspensions and improve wetting in coatings, inks and cleaning products. It can also act as an emulsifier and stabilizer in cosmetic formulations, supporting oil in water emulsions. As an agrochemical adjuvant, it may enhance spray coverage, spread and foliar uptake of pesticides. In polymers and coatings, it can serve as a processing aid and rheology modifier to improve compatibility of hydrophobic additives. Additionally, as a phosphorus-containing compound, it may function as a corrosion-inhibiting additive in metalworking fluids or surface finishes, subject to formulation constraints and local regulations.
