Formulation
Stability
PIGMENT RED 88 is noted to be unstable under acidic conditions, which can lead to the generation of hydrogen sulfide and a distinctly unpleasant 'rotten egg' odor. As an organic pigment, it is generally insoluble in water and most organic solvents but can be effectively dispersed in various mediums.

Safety
Safety Profile
PIGMENT RED 88 has not been specifically reviewed for safety in skincare by the Cosmetic Ingredient Review (CIR) Expert Panel or the SCCS. The U.S. FDA does not list this ingredient (CI 73312) as an approved color additive for cosmetic applications. While hair colorants are subject to extensive safety assessments in the EU, specific data for skincare use is lacking.

Verdict
PIGMENT RED 88 is considered questionable for skincare formulations due to its unapproved status as a cosmetic color additive by the FDA, absence of dedicated safety evaluations for skin use, and potential for stability issues in low pH environments.
