Regulatory Status

EU EU Status permitted
US US Status restricted
US Notes FDA delisted barium sulfate as a color additive and it is no longer authorized under color additive regulations (21 CFR Part 82). If used in US cosmetics, should be positioned under opacifying agent function rather than as a color additive to avoid regulatory conflict. CIR Final Report (June 2014, published IJT 2018) assessed it as safe at current use concentrations with the condition that formulation must be non-irritating.
