What it is
PPG-17/IPDI/DMPA copolymer is a polyurethane-based copolymer made from polypropylene glycol, isophorone diisocyanate, and dimethylolpropionic acid building blocks. In sunscreens it functions as a film former that helps the product spread and set into an even, cohesive layer on the skin. Polymers of this kind are also used to help suspend or stabilize other components in the formula.
Safety & warnings
Polyurethane film formers of this type are large molecules used at modest levels and are generally well tolerated with low irritation potential. It is not a fragrance allergen and is not an oil, so comedogenicity is not a typical concern.
Origin & sourcing
Synthetic polymer produced by reacting polypropylene glycol with isophorone diisocyanate and dimethylolpropionic acid.
