Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Disperse Violet 1” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Confirm INCI/CAS/EC identity.
  3. Review every current GB Annex II–VI match.
  4. Check commencement dates and later statutory instruments.
  5. Verify SCPN, responsible-person, safety-report and labelling duties.
  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. No annex match is not approval and does not cover Northern Ireland, which follows the applicable EU framework.

The record cites GB Cosmetics Regulation, Annex III, entry 265, source version 2026-08-15. 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.
