What substance is commonly used for bone repair cement but is illegal for nail applications?

Methyl Methacrylate (MMA) is commonly used in medical applications, including bone repair cement, due to its effective bonding properties and durability. However, it is considered hazardous for cosmetic nail applications because it can cause allergic reactions, skin irritation, and other harmful effects upon exposure. The use of MMA in salons has been banned in many places, including in Utah, because of these safety concerns.

In contrast, other substances listed, such as methacrylate, oligomers, and plasticizers, may be utilized in nail products under certain conditions, provided they are formulated safely and do not carry the same level of risk associated with MMA. Understanding these distinctions is crucial for nail technicians to ensure client safety and compliance with regulatory standards.
