PPG-12/Smdi Copolymer

What PPG-12/Smdi Copolymer is & what it does

PPG-12/SMDI Copolymer is a synthetic film-forming polymer made by reacting a polypropylene-glycol segment with a saturated diisocyanate. In sunscreens and other leave-on products it forms a flexible water-resistant film that helps the product cling to skin and resist rub-off. This film-forming property is often used to support long-lasting, water-resistant claims.

What does PPG-12/Smdi Copolymer do in skincare?

PPG-12/SMDI Copolymer is a film-forming polymer. In sunscreens and leave-on products it forms a flexible, water-resistant film that helps the product cling to skin and resist rub-off. This makes it useful for long-lasting and water-resistant formulas.

Is PPG-12/Smdi Copolymer safe?

PPG-12/SMDI Copolymer is a synthetic film former used in cosmetics and is generally considered well tolerated as used in products. As with any ingredient, sensitive skin may occasionally react. Patch testing a new product is reasonable if your skin reacts easily.

Is PPG-12/Smdi Copolymer natural or synthetic?

PPG-12/SMDI Copolymer is synthetic. It is made by reacting a polypropylene-glycol segment with a saturated diisocyanate to build a film-forming polymer, so it is a manufactured ingredient rather than a naturally occurring one.
