CI 77002

CI 77002 is an inorganic pigment classified as Iron Oxides Black. It is a naturally occurring mineral compound used in cosmetic formulations as a colourant. In skincare products, it serves purely to impart colour to creams, serums, masks and other preparations.As a mineral pigment, CI 77002 is insoluble in water and remains on the surface of the skin rather than being absorbed. It does not provide direct therapeutic benefit to skin health; its role is cosmetic only.

CI 77002 works through light absorption and reflection. As an inorganic iron oxide, it absorbs certain wavelengths of visible light, creating the visual effect of colour in the product. Because it is insoluble, it does not dissolve into the formulation but disperses as fine particles throughout the base.The pigment remains on or near the skin surface and is not systemically absorbed, making it suitable for topical cosmetic use.

CI 77002 requires no special application technique — it is simply present in formulated products at the concentration determined by the manufacturer. Shake or stir products if the pigment has settled, as it is insoluble and may separate slightly from the base formula over time.

CI 77002 is well-tolerated and approved for use in cosmetics across major regulatory bodies. It is unlikely to cause irritation; however, individuals with known sensitivities to iron oxides should verify the full ingredient list before use.
