Cosmetics biocide chlorocresol to be listed as toxic substance in Canada

On 1 April 2023, the Canadian government announced that they are taking steps to limit the potential risks associated with the use of chlorocresol in cosmetics by proposing an order to add it to the list of toxic substances. This announcement was published in the Canada Gazette. The proposed order would add chlorocresol to Schedule 1 of the Canadian Environmental Protection Act (CEPA). Stakeholders have until 31 May to provide feedback on the proposed order. After this date any subsequent risk management proposals will be subject to their own consultation process if the order is finalized. 

Chlorocresol is a biocide that is commonly used in cosmetics, non-prescription drugs and health products for skin irritations, and as a lubricant in food processing facilities. It is also registered as an active ingredient in pest control products in Canada. 

According to Health Canada and Environment and Climate Change Canada (ECCC), any potential risk management actions related to chlorocresol will focus primarily on its use in cosmetics, as this is where there is concern for Canadians. In 2019, the agencies released a draft assessment which indicated that chlorocresol, when used in moisturizers and lotions, may have adverse effects on the adrenal glands. The finding was confirmed two years later, prompting the recommendation to add chlorocresol to Schedule 1 and to include it on Canada’s Cosmetic Ingredient Hotlist as a prohibited or restricted substance.
