About
A cyclohexene alkyd resin used as a flexible film former in nail polish and styling products. Limited public safety data — considered low-concern at typical polymer levels.
Trimethylol propane cyclohexene dicarboxylate is a polyester-type alkyd resin formed from trimethylolpropane and a cyclohexene dicarboxylic acid. It is used almost exclusively in nail lacquers and some hair fixatives as a flexible, water-resistant film former. Public toxicology data is sparse; the polymer itself is of high molecular weight and not expected to be dermally absorbed. Concern centres on residual monomers or cyclohexene dicarboxylic anhydride traces rather than the polymer. No EU CosIng restrictions noted; CIR has not published a dedicated review.
