Ppg-12 Smdi Copolymer
Also known as PPG-12/SMDI copolymer, polypropylene glycol-saturated MDI copolymer, polyurethane (PPG-12 based)
“No regulator has issued a verdict on this ingredient.”
No ingredient-specific safety data found. PPG-12/SMDI Copolymer does not appear in the CIR Quick Reference Table (Dec 2025) and is not among the 66 polyurethane-numbered ingredients covered by the CIR Final Report on Safety Assessment of Polyurethanes (Sept 2017). PubMed searches for 'PPG-12 SMDI copolymer safety cosmetic' and 'polypropylene glycol SMDI copolymer skin safety dermal' returned zero results. The CIR polyurethane report confirms that for its 66 covered Polyurethane-N ingredients, the panel determined no detectable residual isocyanate or monomers; however, this finding cannot be attributed to PPG-12/SMDI Copolymer as a distinct INCI not covered by that report.
Functions as a film-former and texture modifier in cosmetics
Polyurethane chemistry generally provides skin-substantive film-forming properties
- · No ingredient-specific CIR safety assessment found for this INCI
SMDI (saturated methylene diphenyl diisocyanate) is a diisocyanate precursor; residual diisocyanates are known sensitizers, though polyurethane end-products are generally considered low-risk when fully reacted
