What it is
CI 77007 refers to ultramarines, a family of synthetic inorganic pigments based on a sodium aluminosilicate framework with sulfur that produces blue, violet, and pink shades. In cosmetics they are used to tint products and, in small amounts, to counteract yellow tones or the cast left by other ingredients. They are insoluble mineral pigments used by dispersion.
Safety & warnings
Used as a permitted cosmetic colorant within regulated limits, including products applied around the eyes where many other dyes are restricted. As an inorganic mineral pigment it is generally well tolerated and works by dispersion.
Origin & sourcing
Synthetic; manufactured by heating mixtures of clay, sodium compounds, sulfur, and other raw materials to form the aluminosilicate pigment, mirroring the structure of the natural mineral lapis lazuli.
