What is Hema? - Updated April 2023

2-Hydroxy Ethyl Methacrylate Agent (HEMA)

2-Hydroxy Ethyl Methacrylate Agent (HEMA) is a common ingredient in nail products, particularly in monomer and gel formulations. It is primarily used for its adhesive properties and as a diluent.

However, it is important to note that HEMA is a known allergen and can cause contact dermatitis in individuals who are sensitive to it. This is why it is important for nail technicians to take precautions to avoid uncured products from touching the skin to prevent sensitization.

In fact, the use of HEMA in home-use gel polish kits was banned in 2021 due to safety concerns. This highlights the importance of proper training and understanding of the potential risks associated with nail products, particularly for those who are not trained professionals.

It is also worth noting that the nail plate acts as a natural barrier, preventing HEMA solutions from penetrating via the nail bed. However, it is still important to use HEMA in the correct concentration percentages and in high-quality products to ensure safety for those without a known allergy to it.

HEMA can still be used in professional nail products, as long as they are clearly marked and labeled as containing the ingredient and include an allergy warning. This is an important precautionary measure to ensure that professionals and clients are aware of the potential risks associated with the use of HEMA and can take appropriate measures to avoid any adverse reactions.

Important Safety Precautions with HEMA

It is also important to note that professionals should follow proper safety protocols when working with any potentially hazardous chemicals or ingredients, such as using protective gloves and ensuring adequate ventilation in the workspace.

Overall, while HEMA can still be used in professional nail products, it is important to take appropriate precautions and ensure that consumers are fully informed about the potential risks associated with its use.
