• Hydrophobic Surface: Available with treatments for smudge-proof and waterproof formulas.
• Neutral Undertone: Provides a true black without unwanted blue or green tints.

• Q: Is this black iron oxide "Carbon Black"?

  A: No. It is a mineral-based magnetite (Fe3​O4​). It is safer for eye-area use and easier to formulate in various cosmetic bases than carbon black.

• Q: Does it comply with Japanese cosmetic standards?

  A: Yes, our cosmetic grade meets the requirements for the US, EU, and Japanese (MHLW) markets.

Cosmetic Innovation Services

We offer "Surface Functionalization," providing black oxides coated with silica or dimethicone for improved "skin-feel" and easier dispersion in oils.

Custom Particle Size: We can provide "Jet-Black" micronized powders for ultra-smooth liquid eyeliners.

The Science of Ferrimagnetic Intensity

The depth of black in CI 77499 is a result of "Inter-Valence Charge Transfer." In the magnetite crystal, iron exists in both Fe2+ and Fe3+ states. Electrons can hop between these states, absorbing light across the entire visible spectrum. The science behind our cosmetic grade lies in protecting this "Valence Balance." By preventing oxidation to the trivalent state (which would turn the pigment brown), we ensure the black stays intensely dark and neutral, providing the high-definition contrast required for professional makeup.
