What Is CI 77015?

CI 77015 is an iron oxide pigment classified as a synthetic colourant. It is commonly used in the cosmetic industry to impart colour to products, ranging from foundations and concealers to tinted moisturisers and other skincare formulations. Iron oxides are among the oldest and most widely used colour additives in cosmetics.

This particular iron oxide serves a purely aesthetic function within products — it does not have active skincare benefits of its own. Its role is to provide consistent colour and appearance, helping products blend seamlessly with different skin tones or achieve a desired visual effect.

How It Works

CI 77015 functions as a colorant by absorbing and reflecting light in a way that produces visible colour. It disperses throughout the product formula and deposits onto the skin during application, creating the intended colour effect.

Unlike active skincare ingredients, it does not penetrate the skin or interact with biological processes. Its presence is purely cosmetic — it enhances the visual appearance of a product without contributing to its skincare efficacy.

Clinical Evidence & References

Iron oxides have an extensive history of safe use in cosmetics and are approved for use across major regulatory bodies, including the FDA and European Commission. Dermatological data supports their safety as colour additives in topical products.

There is no expectation of clinical efficacy data for this ingredient, as it is a cosmetic colorant rather than a therapeutic agent. Research has focused on safety and stability rather than skincare benefit.

How to Use

CI 77015 will be present in any product that lists it on the INCI declaration, so no special application technique is required. Simply use the product as directed. The colour it provides should remain consistent throughout the shelf life of the product if formulated and stored correctly.

Safety & Precautions

CI 77015 is generally well-tolerated and approved for cosmetic use globally. It is considered safe for all skin types, including sensitive skin, though individuals with known sensitivities to iron oxides should patch test first.
