MMA in Nail Products — Is It Safe?
Also known as: Methyl Methacrylate, Methyl 2-methylacrylate
About MMA
MMA (Methyl Methacrylate) was widely used in acrylic nail systems but has been banned in nail products in many US states due to safety concerns. It bonds extremely strongly to the natural nail, making removal damaging or impossible without professional help. Forced removal can rip the natural nail plate. MMA also has sensitization potential similar to other methacrylates.
Quick Answer
- MMA is different from PMMA; polymethyl methacrylate powder is not the same as liquid methyl methacrylate monomer.
- MMA exposure concerns include nail damage, contact dermatitis, and inhalation exposure in salons.
- If a salon product has an unusually sharp odor or is very difficult to remove, ask what monomer is being used.
Common product types
Regulatory status
FDA states it acted against 100% methyl methacrylate monomer artificial nail products after injury complaints, but no FDA regulation specifically prohibits MMA in cosmetic products. California DTSC initiated rulemaking in 2024 for nail products containing MMA above 1,000 ppm.
