What Is CI 77266?
CI 77266 is a synthetic inorganic pigment classified as a colorant in cosmetics. It belongs to the family of colour additives regulated under the Colour Index system, which standardises pigments used across the beauty and personal care industry. This ingredient is insoluble in water and is used to impart colour to skincare products, foundations, and other formulations.
As a mineral-based pigment, CI 77266 is chemically stable and does not dissolve into the skin. Its primary role is aesthetic—to provide consistent colour to a product formulation. It is not designed to deliver therapeutic benefits to the skin itself, but rather to serve a cosmetic function.
How It Works
CI 77266 works through physical colour dispersal rather than chemical interaction. Once dispersed throughout a formulation, the pigment particles remain suspended and reflect light to create the desired colour. Because it is inorganic and insoluble, it sits on and within the product matrix without breaking down or penetrating the skin barrier.
Clinical Evidence & References
As a cosmetic colorant, CI 77266 has not been the focus of significant clinical skincare research, as it is not designed to influence skin health or condition. Regulatory bodies including the FDA and EU have approved its use in cosmetics within specified limits based on safety assessments of inorganic pigments. The ingredient is considered well-tolerated in topical applications.

How to Use
CI 77266 is incorporated into products during manufacturing and requires no special application technique. Simply use the product as formulated. The pigment will not transfer significantly onto skin or clothing, though some very light marking is possible with heavily pigmented products.
