PEG-8 PHOSPHATE

What Is PEG-8 PHOSPHATE?

PEG-8 phosphate is a PEG ester of phosphoric acid. It functions as a mild anionic emulsifier with pH-buffering properties. The phosphate group provides a negative charge for electrostatic stabilization of emulsions, while the PEG-8 chain ensures water solubility. Used in creams, lotions, and other emulsified cosmetic products.
