CI 77492
CI 77492 is the yellow iron oxide pigment found in colour cosmetics. It is also listed chemically as C.I. Pigment Yellow 42. In foundations, concealers, powders and other makeup products, it is one of the colours used to build the visible shade rather than an ingredient intended to treat the skin.
CI 77492: what it is
CI 77492 is the yellow iron oxide pigment found in colour cosmetics. It is also listed chemically as C.I. Pigment Yellow 42. In foundations, concealers, powders and other makeup products, it is one of the colours used to build the visible shade rather than an ingredient intended to treat the skin.
It is an inorganic colour made chiefly of hydrated iron oxide. That sets it apart from plant-derived colourants and from red or black iron oxide pigments: CI 77492 supplies the yellow contribution within the iron-oxide pigment family. The final cosmetic shade depends on how it is combined with the other coloured components of the formula.
CI 77492: what it does in cosmetics
CI 77492 is used to colour a cosmetic or adjust its shade. In practical terms, it can help a foundation reach a warmer undertone, soften an overly pink shade, or take part in the pigment blend used for different skin-tone shades. Seeing it on a label points to a visual purpose.
The European cosmetic reference classifies the ingredient as a colourant. That supports its role in colour appearance and coverage, but it does not make the pigment a treatment for hydration, acne, dark spots or wrinkles. The result depends on the amount used, the product base and the accompanying pigments; the name alone does not reveal colour intensity or the performance of a particular product.
