Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A specialty film-forming polymer used in nail and UV-cured cosmetic products — it creates durable, flexible films. Safe once fully cured; no significant concerns in finished products.
Tris-HEA IPDI Isocyanurate Trimer is an isophorone diisocyanate (IPDI) isocyanurate trimer capped with 2-hydroxyethyl acrylate. It functions as a film-forming agent, commonly used in UV-curable nail gels and coatings. The fully cured polymer is inert and non-toxic. No GHS hazard codes or EU restrictions are listed for the cosmetic-grade ingredient. As with all acrylate-containing ingredients, uncured monomer can be a skin sensitiser, but once polymerised/cured, the risk is negligible.
Function
Skin benefits
- Creates durable, flexible protective films
- Excellent adhesion and wear resistance in nail products
Known concerns
- Uncured acrylate monomers can cause skin sensitisation
- Should only contact skin in fully cured/polymerised form
- Environmental persistence as a synthetic polymer
