TL;DR. This ingredient is used as an inorganic colorant, adding yellow, black, olive, brown, or muted tone correction in makeup, skin care, hair color, and tinted SPF formulas. It is valued for opacity, color stability, and compatibility with anhydrous, emulsion, and powder systems.
What does Ci 77492 • Ci 77499 do in a cosmetic formula?
This ingredient is used as an inorganic colorant, adding yellow, black, olive, brown, or muted tone correction in makeup, skin care, hair color, and tinted SPF formulas. It is valued for opacity, color stability, and compatibility with anhydrous, emulsion, and powder systems.
Is Ci 77492 • Ci 77499 clean?
From a clean-beauty perspective, this ingredient is generally well-tolerated and not a common sensitizer. The main quality consideration is tight control of trace metal impurities, which reputable cosmetic grades are purified and tested to meet.
Is Ci 77492 • Ci 77499 sustainable?
This material is mineral-derived or synthetically made from abundant inorganic feedstocks. It does not biodegrade in the usual organic sense, but it is inert, stable, and not associated with meaningful bioaccumulation in cosmetic use.
Is Ci 77492 • Ci 77499 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s purity and colorant criteria. Its Green Chemistry fit is strongest on stability, low reactivity, and low irritation, with weaker marks for non-renewable mineral sourcing and limited biodegradability relevance.
How does Ci 77492 • Ci 77499 work chemically?
The molecule is an insoluble inorganic crystalline pigment, with the two grades contributing different undertones through hydrated and mixed-valence crystal structures. Typical use ranges vary widely by product, from trace tint adjustment below 1% to much higher levels in pressed powders and complexion products, and it is stable across normal cosmetic pH, heat, light, and oxidation conditions.
