Verification workflow and record completeness

Before using this result in a compliance decision

  1. Confirm that “Lithium hydroxide” 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 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 searchable spreadsheet is an aid; the legal Group Standard and incorporated notices remain authoritative.

The record cites Schedule 5, reference 15b, source row 32, 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.
