Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “1-(4’-Aminophenylazo)-2-methyl- 4-(bis- 2-hydroxyethyl) aminobenzene HC Yellow No 7 CAS No 104226-21-3” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search all ACD annexes by name and identifiers.
  3. Apply product type, maximum level and warning conditions.
  4. Confirm the target member state's adoption and transition date.
  5. Complete the local notification and responsible-company requirements.
  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. Regional annex coverage does not replace member-state implementation dates, notifications or national deviations.

The record cites ASEAN Annex III, reference 272, source version 2026-1. 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.
