Safety
Safety Profile
While the Environmental Protection Agency (EPA) considers CI 74160 to be of low concern and generally non-toxic in small concentrations, its regulatory status in cosmetics varies significantly. It is not permitted in cosmetics by the US FDA. In the European Union, it is allowed for general cosmetic use, though banned from hair dyes due to a lack of manufacturer data submission to the SCCS, not a negative health assessment. EWG classifies it as 'Unacceptable' for EWG VERIFIED products due to these high use restrictions. Studies suggest low acute toxicity and low eye irritation, but indicate low to moderate skin irritation and weak sensitization, with a reported case of allergic contact dermatitis to PB 15, suggesting rare allergic reactions are possible.

Verdict
Despite its stability and perceived low general toxicity, Pigment Blue 15 is deemed questionable for precision skincare due to its prohibition in US FDA-regulated cosmetics, 'Unacceptable' EWG VERIFIED rating, and documented, albeit rare, potential for sensitization.
