PPG-12/SMDI Copolymer Description
PPG-12/SMDI copolymer is a polymer that serves as a film-forming agent in cosmetics products. The SMDI portion stands for Saturated Methylene Diphenyl Diisocyanate, whose monomers (molecules that bond with other molecules to create polymers) are combined with an ultra-light polypropylene glycol (PPG).Along with film-forming, PPG-12/SMDI copolymer also offers fixative properties to keep key ingredients suspended and helps to condition skin. Usage levels range from 1–5% when it is part of a blend. It’s considered non-irritating and can play a supporting role in creating pleasing liquid and gel textures plus keep such textures stable.
