Annexes II, III, IV, VI and VII covering prohibited, restricted and positive-list substances.

Verification checklist

  1. Search all ACD annexes by name and identifiers.
  2. Apply product type, maximum level and warning conditions.
  3. Confirm the target member state's adoption and transition date.
  4. Complete the local notification and responsible-company requirements.

Official market sources

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Undec-10-enoic acid and its salts (+) Undecylenic acid (CAS No. 112-38-9) /Potassium undecylenate (CAS No. 6159-61- 47)/ Sodium undecylenate (CAS No. 3398-33- 2)/Calcium undecylenate (CAS No. 1322-14-1) / TEA- undecylenate (CAS No. 84471-25-0)/ MEA- undecylenate (CAS No. 56532-40-2)” 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 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. Regional annex coverage does not replace member-state implementation dates, notifications or national deviations.

The record cites ASEAN Annex VI, reference 18, 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.
