About Hydroquinone

Hydroquinone is used as a polymerization inhibitor (stabilizer) in acrylic and gel nail products to prevent premature curing during storage and transport. It is classified as a possible human carcinogen (Group 3 by IARC) and is banned in cosmetic products in the EU. Occupational exposure in nail technicians handling bulk product is a concern. Even trace residues in finished products raise regulatory scrutiny.
