Key Properties & Benefits

• Colouring
• Depth
• Supplied with the CI number, particle specification and purity data needed for colour-cosmetic work.

Uses & Applications

Black Iron Oxide is used in foundation, concealer, blush, eyeshadow, lipstick, mineral makeup and soap.

Typical applications from the catalogue record: Mascara, eyeliner, foundation shading, mineral makeup.

Colour work is done on a grind or dispersion step; the level is set by the shade target, and permitted application area must be checked before the shade is locked.

Handling note: Weigh accurately and dissolve or disperse fully before the batch is judged — undissolved powder reads as grit in the finished product.

How to Use — Recommended Use Level

General rule: always begin at the lower end of the range, confirm the level against the supplier technical data sheet, and validate stability, pH, colour, odour and preservative efficacy on the finished formulation before scaling up.

Technical Specification

Technical Notes

Extremely high tint strength; dose in fractions of a percent when shading.

Regulatory Note

Colorants are a separately regulated category. Permitted colours, the application areas they may be used in (general, eye area, lip, mucous membrane) and purity specifications vary by market, and batch certification applies to certain colours in the United States. Confirm the CI number, the permitted application area and the certification status for each destination.

Supplier diligence required: Permitted colour, application area and purity specification vary by market; confirm CI status and certification.

Sold as a cosmetic raw material for professional formulation. A published INCI name does not by itself authorise use: the buyer is responsible for confirming permitted status, maximum concentration, restrictions by product type, labelling and claim rules in every market the finished product is sold in. In India, cosmetics fall under the Drugs and Cosmetics Act 1940 and the Cosmetics Rules 2020 administered by CDSCO, with BIS standards (including IS 4707 Part 2) listing restricted substances. The EU applies Regulation (EC) No 1223/2009 and its Annexes; the United States applies the FD&C Act as amended by MoCRA; Korea, Japan and China operate their own positive lists and functional-cosmetic frameworks. Every finished product needs its own safety assessment.
