What it is
Polyglyceryl-10 Diisostearate is formed by esterifying decaglycerol with two isostearic acid groups, creating a mild nonionic surfactant. In sunscreens and lotions it helps blend oil and water phases into a stable emulsion and contributes a smooth, conditioned skin feel. It is favored in gentle and PEG-free formulations as a milder alternative to many traditional emulsifiers.
Safety & warnings
Polyglyceryl esters are widely regarded as mild, low-irritation emulsifiers and are commonly chosen for sensitive-skin and PEG-free formulas. They are generally well tolerated.
Origin & sourcing
Synthetic ester typically made from renewable feedstocks. The polyglycerol portion is derived from glycerin and it is reacted with isostearic acid to form the finished emulsifier.
