Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “푸로쿠마린류(예 : 트리옥시살렌, 8-메톡시소랄렌, 5-메톡시소랄렌)(천연에센스에 자연적으로 함유된 경우는 제외.다만, 자외선차단제품 및 인공선탠제품에서는 1ppm 이하이어야 한다.)” 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 official record identifies the substance as prohibited for cosmetic use in the stated market scope. Do not rely on a formulation containing this identity until the cited source, effective date and exact substance match have been verified.

A prohibition entry may contain no separate condition text because the regulatory outcome is the prohibition itself. 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 1, record 1-1123, 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.
