To strengthen the management of safety risk substances in cosmetics, on Mar. 10, 2022, China National Institutes for Food and Drug Control (NIFDC) released an announcement seeking public comments on benzene (CAS No. 71-43-2) limitation requirements. According to the risk assessment results, the limit of benzene in cosmetics is proposed to be 2mg/kg. 1 Stakeholders can send suggestions to email@example.com before Mar. 31, 2022.
Benzene is classified as a human carcinogen. Exposure to benzene can occur by inhalation, orally, and through the skin, and it can result in cancers including leukemia and blood cancer of the bone marrow and blood disorders which can be life-threatening. 2 Trace amounts of benzene introduced into cosmetics can pose a potential hazard to human health.
Engineers believe that the introduction of benzene into the product may be due to the following reasons 3:
Some cosmetic ingredients contain benzene ring structures, which may leave traces of benzene in the process of synthesis or chemical reaction;
Organic propellants are generally added to aerosol products (such as Propane, butane, etc.), these organic propellants may have residues of benzene;
Cosmetic ingredients may come into contact with benzene during storage and transportation, and then bring benzene into cosmetics;
