Resorcinol is a chemical compound commonly used in products such as hair dyes, skin care products, and topical medications. However, it can be contaminated with impurities such as benzene, which is a known carcinogen. Exposure to high levels of resorcinol impurities can lead to serious health consequences, including cancer and organ damage. It is important to ensure that products containing resorcinol are properly tested for impurities and are used safely.
