Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Alkali sulfides” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search English/French names and CAS identifiers.
  3. Apply every restriction, concentration and label warning.
  4. Check Food and Drugs Act/Cosmetic Regulations requirements.
  5. Recheck the current Hotlist before notification or sale.
  6. Document the source version and recheck the regulator before manufacture, notification or market placement.

Questions this page answers

This substance is not unrestricted: cosmetic use is subject to the conditions in the cited official record. Check product type, body area, concentration, purity and warning requirements before deciding whether a formulation is compliant.

If this row does not reproduce conditions, open the cited official detail because omission does not mean unrestricted use. The Hotlist is an administrative compliance tool, not an exhaustive safety approval list.

The record cites Hotlist restricted entry 7, source version Health Canada Hotlist 2025-08-13. Open the official source.

No. CAS helps resolve identity, but jurisdictions can classify the same substance differently and can apply different product scopes, limits, warnings and transition dates.

Stable citation

Alkali sulfides. Hotlist restricted entry 7. Canada. Source version Health Canada Hotlist 2025-08-13. CosIng Checker regulatory record: https://cosingchecker.com/regulations/ca/records/497/

Cite the regulator as the legal authority. This page is a structured evidence index and verification aid, not a substitute for the official text or professional legal assessment.

Interpretation and limits for Canada

This substance is not unrestricted: cosmetic use is subject to the conditions in the cited official record.

Check product type, body area, concentration, purity and warning requirements before deciding whether a formulation is compliant.

How to interpret the legal role

The authority uses this source as compliance guidance; the underlying legislation remains controlling.
