HEMA-free is a term used in the cosmetic context to indicate that a product does not contain the ingredient HEMA (Hydroxyethyl Methacrylate).
HEMA stands for HydroxyEthyl MethAcrylate, a chemical compound commonly used in nail products, especially in sculpting gels, base coats and gel polishes. It ensures strong adhesion of the product to the nail plate, contributing to the longevity of the manicure. However, in some individuals, HEMA can trigger allergic reactions, most often appearing as redness, itching, burning, or a rash around the nails and fingers. Allergies may develop in both professionals (nail technicians) and users, especially if the product comes into contact with the skin.
Although HEMA is not a banned ingredient, its use is strictly regulated, especially within the European Union. It is permitted in professional nail products but is not intended for home use and must not come into contact with the skin. For this reason, products containing HEMA are often labelled as “for professional use only”.
Products labelled as HEMA-free have been developed as a safer alternative and are increasingly used in beauty salons and by individuals with sensitive skin or a tendency toward allergic reactions. It is important to understand that the HEMA-free label means the product does not contain HEMA, but this does not necessarily exclude all related compounds. For example, ingredients such as Di-HEMA Trimethylhexyl Dicarbamate may still be present in some formulations that carry the HEMA-free label. These compounds are considered more stable and gentler alternatives and, in practice, often do not cause the same irritation that HEMA can trigger in sensitive users. Therefore, products that contain Di-HEMA but not HEMA may be a suitable option for individuals prone to allergies.
