How to read these entries. Use levels and pH ranges are typical formulation starting points for a cosmetic raw material, not approvals. A published INCI name does not by itself authorise use: confirm permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market you sell into, and give every finished product its own safety assessment. Entries marked with a regulatory flag carry a binding limit somewhere — the product page states which framework and what the limit is.
