Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Chloramine T and related compounds” 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 official record identifies the substance as prohibited for cosmetic use in the stated market scope. Do not rely on a formulation containing this identity until the cited source, effective date and exact substance match have been verified.

A prohibition entry may contain no separate condition text because the regulatory outcome is the prohibition itself. The Hotlist is an administrative compliance tool, not an exhaustive safety approval list.

The record cites Hotlist prohibited entry 136, 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.
