Verification checklist

  1. Confirm INCI/CAS/EC identity.
  2. Review every current GB Annex II–VI match.
  3. Check commencement dates and later statutory instruments.
  4. Verify SCPN, responsible-person, safety-report and labelling duties.

Official market sources

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Undecylenic acid, potassium undecylenate, sodium undecylenate, calcium undecylenate, TEA-undecylenate, MEA-undecylenate” 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 identity appears on a market positive list for the list function represented by the source record. Confirm that the intended function and product use fall within the list scope and every stated condition.

Positive-list presence is purpose-specific and is not blanket approval for every cosmetic 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 V, entry 18, 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.
