CI 77120

CI 77120, also known as barium sulfate, is an inorganic mineral pigment derived from the naturally occurring mineral barite. In cosmetics, it is used as a colorant to provide white, opaque coverage to formulations. It is insoluble in water and does not dissolve on the skin.As a cosmetic colorant, CI 77120 serves a functional purpose in skincare products by modifying appearance and texture. It is one of a family of inorganic pigments approved for cosmetic use under strict regulatory guidelines.

CI 77120 works as a physical colorant by scattering and reflecting light, which creates the visual appearance of white or pale colour in a product. Because it is insoluble, it remains on the surface and does not penetrate the skin.The pigment particles are typically very small, which allows them to distribute evenly throughout a formulation without settling or clumping. This physical mechanism means the ingredient does not rely on chemical reactions to produce its colour effect.

CI 77120 is typically incorporated into formulations by the manufacturer rather than applied directly. If using a product containing this ingredient, apply as directed on the product label. As with all skincare, patch testing on a small area first is sensible if you have a history of sensitivity to inorganic pigments or mineral-based products.

CI 77120 is generally well-tolerated and approved for cosmetic use. It is non-toxic at cosmetic concentrations and non-sensitising for most people, though those with specific sensitivities to mineral pigments should patch test first.
