CI 77267

CI 77267 is a synthetic iron oxide pigment classified as a cosmetic colorant. It belongs to the family of iron oxides — naturally occurring minerals that have been refined and standardised for use in cosmetics. In skincare products, it serves primarily as a colouring agent rather than an active ingredient.This pigment is insoluble in water and does not penetrate the skin barrier. Instead, it remains on the surface or within the formulation matrix, where it contributes to the visual appearance and aesthetic consistency of the product.

CI 77267 functions as a physical colorant by absorbing and reflecting light. Because it does not dissolve in the formulation, it remains as suspended particles that impart colour to the product.As a topical ingredient, it sits on or near the skin surface and does not undergo metabolic conversion. It is generally considered inert from a biological perspective, meaning it does not trigger chemical reactions within or on the skin.

No specific usage restrictions apply to products containing CI 77267. Use according to the product instructions — typically daily application for serums, creams, or other leave-on formulations. If you have very sensitive skin or a history of reactions to coloured cosmetics, perform a patch test first, though reactions are uncommon.

CI 77267 is well-tolerated and suitable for use on all skin types. It is non-toxic and non-sensitising at cosmetic concentrations. Individuals with known sensitivity to iron oxides are rare but should avoid products containing this ingredient.
