Polyglyceryl-10 Isostearate
What Polyglyceryl-10 Isostearate is & what it does
Polyglyceryl-10 Isostearate is a non-ionic emulsifier made by joining isostearic acid to a polyglycerol backbone of ten glycerin units. In creams, lotions, and sunscreens it helps blend oil and water phases into a stable, uniform emulsion and can also act as a mild surfactant and solubilizer. Its plant-derived, PEG-free structure makes it a common choice in formulas aiming for a gentle, naturally derived profile.
