Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “리튬하이드록사이드” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Match the Korean canonical substance name and identifiers.
  3. Review all Appendix 1 and 2 matches and conditions.
  4. Check functional-cosmetic and positive-list requirements where applicable.
  5. Confirm current MFDS notice, responsible seller and label obligations.
  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. Korean source wording is canonical and other positive lists/notices may still apply to the formulation.

The record cites 화장품 안전기준 등에 관한 규정, 별표 2, record 2-286, source version 2026-19. 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.
