Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Disodium tetraborate pentahydrate; borax pentahydrate [12]” and every CAS/EC identifier refer to the material in your supplier specification.
  2. Search exact identity across Schedules 4–8.
  3. Apply use, concentration and warning conditions.
  4. Check hazardous-substance classification and Group Standard scope.
  5. Confirm the latest legal instrument, not only the spreadsheet.
  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. The searchable spreadsheet is an aid; the legal Group Standard and incorporated notices remain authoritative.

The record cites Schedule 4, reference 1396, source row 1496, source version effective-2026-01-01. 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.
