PPG-12 is the acronym for "polypropylene glycol", the polymer of propylene glycol (1,2-propanediol), a dihydric alcohol. The number after "PPG" indicates the average number of propylene glycol molecular units, for "PPG-12" this is 12 propylene glycol molecular units. "SMDI" is the acronym for methylenedicyclohexyl isocyanate "copolymer" bistructural polymers, which are composed of 2 different monomer units (here PPG-12 and SMDI).

The PPG-12/SMDI copolymer is used in cosmetic formulations. The substance mixture acts as an emollient (makes the skin smooth and supple), hair fixative, skin care product and as a film former (forms a film on skin, hair or nails when applied).
