What it is
PPG-3 dipivalate is a liquid ester made from a short polypropylene glycol backbone esterified with pivalic (neopentanoic) acid. It is used as an emollient and skin-conditioning agent that imparts a light, smooth, non-greasy slip and can help solubilize other ingredients. It is common in fluid sunscreen and emulsion formulas where an elegant skin feel is desired.
Safety & warnings
This synthetic emollient ester is generally well tolerated and is valued for its light, low-residue feel. Its branched pivalate structure tends to give a dry, non-occlusive finish, and it is not considered a notably comedogenic material. It is not a fragrance allergen.
Origin & sourcing
Synthetic. It is produced by esterifying polypropylene glycol with pivalic acid to form the diester.
