About

A UV-curable polycaprolactone polymer for nail products — forms flexible, durable nail coatings with methacrylate end caps.

Bis-Methacryloyloxyethylcarbamoyl Polycaprolactone is polycaprolactone endcapped with 2-isocyanatoethyl methacrylate. CosIng-listed for nail conditioning. Polycaprolactone is a biodegradable polyester; the methacrylate end caps enable UV-curing for durable nail coatings. The cured polymer is inert, but residual methacrylate monomers are established contact allergens. No GHS codes on the finished polymer. Safety depends on cure completeness.
