DIMETHYLOL BUTANOIC ACID/IPDI/PPG-17/PPG-34 COPOLYMER
Safety score · 0–100
Moderate
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A polyurethane-style film former built around IPDI (isophorone diisocyanate). Cured polymer is inert, but residual diisocyanate is a respiratory sensitizer and EU REACH restricts its presence — formulation grade matters.
Function
Skin benefits

- Improves wear and water resistance
Known concerns
- Built on IPDI (isophorone diisocyanate) — respiratory sensitizer in monomer form
- Residual diisocyanate must be tightly controlled
- Microplastic concerns under EU REACH
