About
A toxic barium borate compound with reproductive toxicity (H360) classification that precludes its use in cosmetic formulations in most jurisdictions.
Barium diboron tetraoxide presents significant toxicological concerns. The hazard profile includes H301/H302 (acute oral toxicity), H332 (harmful if inhaled), and H360 (may damage fertility or the unborn child). The reproductive toxicity classification is particularly significant for a cosmetic ingredient. Barium compounds as a class are treated with regulatory caution in cosmetic applications, and this substance is not listed in any EU annex as permitted for cosmetic use.
Known concerns
- H360 reproductive toxicity
- H301/H302/H332 acute toxicity
