In February 2025, Canada updated its Cosmetic Ingredients Hot List, incorporating new restrictions affecting several key ingredients used in cosmetic products. These include:
Retinal, retinol, and their esters: The update introduces stricter limits on the concentration and use of these compounds, which are essential in anti-aging and skin-enhancing formulas, due to their potential adverse effects under certain exposure conditions.
Thioglycolic acid esters: These compounds, used for their smoothing properties and in hair treatments, must now be evaluated under more rigorous regulations to avoid risks to consumer health.
Cresols and their derivatives: Restrictions on the use of these ingredients have been established due to their association with adverse reactions, seeking to reduce exposure to potentially irritating or toxic substances.
Peroxides and peroxide-generating compounds, including benzoyl peroxide : These ingredients, primarily used in acne treatments, will need to meet new usage limits to minimize the risk of irritation and other unwanted side effects.
These measures require all cosmetics marketers in Canada to review and adapt their products to ensure their safety and compliance with current regulations.
