Health Canada Cosmetic Ingredient Hotlist Explained

What the Health Canada Cosmetic Ingredient Hotlist is, how prohibited and restricted ingredients are handled, and how to check your formula and label against it.

Last reviewed April 27, 2026

The Health Canada Cosmetic Ingredient Hotlist is the list of substances that are prohibited or restricted in cosmetics sold in Canada. Reviewing your formula against it before notification or labelling is one of the highest-leverage things a maker can do.

This guide explains the difference between prohibited and restricted ingredients, how to check your formula, and how hotlist conditions can affect your label.

What the Hotlist is

The Cosmetic Ingredient Hotlist is a Health Canada list of substances that are either prohibited or restricted for use in cosmetics sold in Canada. It is used as part of safety oversight under the Cosmetic Regulations, and Health Canada updates it as new information becomes available.

The hotlist is not the only requirement makers need to follow, but it is one of the most common reasons cosmetic notifications need to be revised. Reviewing your formula against the hotlist early saves rework on both the formula and the label.

Prohibited vs restricted ingredients

Prohibited ingredients should not be used in cosmetic products sold in Canada at all. Restricted ingredients are allowed only under specific conditions — for example, a maximum concentration, a product type restriction (leave-on vs rinse-off), or a required warning statement on the label. Restrictions can also depend on who the product is intended for.

How to check your formula against the Hotlist

Use the FormulaNorth ingredient database to look up each ingredient by INCI name and review its hotlist status. The full hotlist data view is also available so you can browse restricted and prohibited ingredients directly.

  • Identify each ingredient in your formula by INCI name
  • Check hotlist status — prohibited, restricted, or unrestricted
  • Confirm any concentration limits and product-type restrictions
  • Note any required warning statements for the label
  • Document your check date so you can re-verify before launch

Hotlist notes that show up on labels

Some hotlist entries trigger required warning statements on the label. Reviewing your formula against the hotlist before printing packaging avoids costly reprints and keeps your CNF preparation and label content aligned.

How FormulaNorth surfaces Hotlist context

FormulaNorth shows hotlist status on each ingredient page, surfaces warnings inside the formula builder, and includes hotlist context as part of the CNF preparation workflow. Always verify against the current Health Canada hotlist before submitting a notification or printing labels.

Frequently asked questions

Where does the Cosmetic Ingredient Hotlist come from?

The hotlist is published and maintained by Health Canada. It identifies substances that are prohibited or restricted for use in cosmetics under the Cosmetic Regulations.

How often does the Hotlist change?

Health Canada updates the hotlist periodically as new safety information becomes available. Always verify against the current published hotlist on the Health Canada website before submitting a CNF or finalizing labels.

Does a restricted ingredient mean I cannot use it?

Not necessarily. Restricted ingredients can often be used under specific conditions, such as a maximum concentration, product type, or required label warning. Read the full restriction text before deciding whether the ingredient fits your product.

Does FormulaNorth maintain the official Hotlist?

FormulaNorth surfaces hotlist context for ingredients to support your prep work. The official source of truth is the Health Canada Cosmetic Ingredient Hotlist, which makers should consult directly before final review.

What happens if my product contains a prohibited ingredient?

Products containing prohibited ingredients are not compliant for sale in Canada. Reformulate before notification or launch — do not file a CNF for a product that contains a prohibited substance.
