What Is CI 77268:1?

CI 77268:1 is a synthetic iron oxide colorant approved for use in cosmetics. Iron oxides are mineral pigments that have been used in colour cosmetics for decades. This particular variant provides colouration in skincare and makeup formulations without imparting active skincare benefits.

As a colourant, CI 77268:1 serves a cosmetic purpose—giving products their desired shade or appearance. It is insoluble in water and remains stable across a wide pH range, making it suitable for various product types.

How It Works

CI 77268:1 works as a colourant by absorbing and reflecting light across visible wavelengths. The pigment particles remain on or near the skin surface and in the product matrix, providing colour without penetrating the skin or triggering biological responses.

Clinical Evidence & References

As a cosmetic colorant, CI 77268:1 is not typically studied for skincare efficacy because it does not deliver active skincare benefits. Its safety profile in cosmetics is well established through regulatory approval pathways, and it has a long history of use without significant adverse reports when used at approved concentrations.

How to Use

CI 77268:1 is a formulation ingredient controlled by the manufacturer—consumers do not adjust its concentration. It appears in finished products at levels determined during product development. If you have concerns about coloured skincare products, patch-test first, particularly if you have sensitive skin.

Safety & Precautions

CI 77268:1 is approved for use in cosmetics in the EU and UK at specified concentrations. It is generally well-tolerated, though individuals with severe sensitivity to iron oxides are advised to avoid products containing this ingredient.
