Chromium Hydroxide Green

Chromium Hydroxide Green is an insoluble inorganic pigment used to color cosmetics at low concentrations, and as a particulate colorant it is generally associated with low irritancy in most users. However, pigments can still cause mechanical/occlusive irritation on compromised skin and there is a small but real risk of sensitization or irritation in chromium-reactive individuals, so it cannot be treated as inert for highly sensitive or eczematous patients. Safety Notes: Chromium Hydroxide Green is used primarily as a colorant (CI 77289) in consumer cosmetics; at the low end it appears as a trace pigment in tinted skincare (e.g., green-correcting primers, tinted sunscreens, concealers) where only very small amounts are needed to shift tone. At the high end, it can be a major component of the pigment blend in high-pigment color cosmetics (cream/stick concealers, face paints, theatrical body makeup) sold OTC, where total inorganic pigment loading can reach the low-to-mid teens and this pigment can represent a large fraction of that load. Use levels are generally similar for leave-on vs rinse-off when used purely for color, and are constrained mainly by shade requirements and dispersion/texture rather than a specific global percentage cap.
