HEMA in Nail Products — Is It Safe?
Also known as: 2-Hydroxyethyl Methacrylate, 2-hydroxyethyl 2-methylpropenoate
About HEMA
HEMA (2-Hydroxyethyl Methacrylate) is a reactive monomer that bonds to the natural nail plate. Because it penetrates the nail, it can contact the skin beneath — and repeated low-level exposure is enough to trigger permanent sensitization. Once sensitized, you may react to HEMA in dental adhesives, orthopedic cements, wound dressings, and contact lenses. The EU Scientific Committee on Consumer Safety (SCCS) classifies HEMA as a skin sensitizer.
Quick Answer
- HEMA is a small methacrylate monomer used for adhesion and cure performance.
- Risk is highest when uncured gel touches skin, floods cuticles, or is under-cured.
- HEMA-free means HEMA is not disclosed; it does not rule out other acrylates or methacrylates.
