Guidance on Heavy Metal Impurities in Cosmetics

Many heavy metals are not acceptable as ingredients in cosmetic products sold in Canada as they may cause injury to the health of the user, which is in contravention of the general prohibition found in section 16 of the Food and Drugs Act. Yet they may still be found in cosmetics as impurities due to the persistent nature of these substances and the fact that they are found in the natural environment. The purpose of this guidance is to determine and communicate appropriate limits of these impurities in cosmetic products. The focus is on the heavy metals with known significant toxicological properties: lead, arsenic, cadmium, mercury and antimony.

Note: The industry guideline is not a legally binding act or regulation in Canada. Rather, it serves as an interpretive document that consolidates the requirements outlined in relevant acts and regulations. Nonetheless, it is recommended that enterprises adhere to the guidelines to ensure compliance.
