Verification checklist

  1. Search Japanese/English identity and CAS where present.
  2. Apply category and maximum-amount conditions.
  3. Check later MHLW notices against the Japanese source.
  4. Verify marketing licence, notification, labelling and quasi-drug classification.

Official market sources

Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Terephthalylidene dicamphor sulfonic acid” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search Japanese/English identity and CAS where present.
  3. Apply category and maximum-amount conditions.
  4. Check later MHLW notices against the Japanese source.
  5. Verify marketing licence, notification, labelling and quasi-drug classification.
  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. The Japanese text and subsequent notices are canonical; no local match is not a product-compliance conclusion.

The record cites Appendix 4 section 2, entry 13, source version MHLW Notification No. 331 provisional translation, retrieved 2026-08-30. 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.
