Expert Verdict
Dual acrylate/methacrylate sensitization risk - this ingredient contains both HEA and HEMA (2-hydroxyethyl methacrylate) end-caps. HEMA is a well-documented contact allergen and is increasingly scrutinized in the EU nail industry (proposals to restrict HEMA in consumer nail products have been discussed). IPDI residual monomer risk also applies. This ingredient requires the most careful residual monomer control of the group.. Long polytetramethylene glycol chain (repeat unit 41) provides excep...
