Ci 75810

CI 75810 is an inorganic colorant/pigment used at low concentrations to tint products, and as an insoluble particulate it is generally low-reactivity on intact skin. However, colorants can still trigger irritation in highly reactive or barrier-impaired skin via mechanical/particulate effects (especially near eyes or on eczematous skin) and occasional impurity-related sensitivity. Given sensitive-skin safety considerations, I rate it as gentle but not inert. Safety Notes: CI 75810 is chlorophyllin-based (green) colorant and in skincare is most often used at trace levels to tint gels, serums, masks, soaps, and cleansing products; in commercial INCI-listed formulas it commonly appears in the ~0.0001–0.05% range where only a slight green hue is needed. The upper end is represented by highly pigmented consumer-available color-correcting/green-tinted products and some deodorant/soap or mask-type formulas where the colorant load can reach low single-digit percentages (often as part of a chlorophyllin/colour blend or dispersion), with ~5% as a practical top-end seen in OTC products due to staining, shade intensity, and stability constraints. No specific EU/FDA concentration limit is typically assigned to this CI beyond general color additive compliance, so market limits are mainly performance and aesthetics-driven (leave-on tends to be lower than rinse-off to reduce staining).
