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 standards are separate controlled publications; absence from a locally indexed excerpt is not permission.

The record cites IS 4707 (Part 2):2025 Annex B, entry 189, source version IS 4707 (Part 2):2025, fifth revision. 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.
