Ferric Oxide Cosmetic Grade -CAS 1309-37-1
Cosmetic-grade Ferric Oxide is a high-purity natural inorganic iron oxide pigment specially refined for cosmetic formula applications. Adopting advanced purification and ultrafine grinding process, the product has uniform particle size, no coarse particles, pure and stable red tone, and extremely high tinting power and covering power.
Different from organic synthetic pigments, it has super strong light resistance, weather resistance and oxidation resistance, no color fading, discoloration or color migration during long-term use and storage. It features excellent chemical stability, stable performance in acid-base environment, no reaction with cosmetic base materials.
The raw material is strictly controlled for heavy metals, non-toxic and non-irritating, safe for skin contact, fully compliant with FDA, EU and domestic cosmetic safety standards. With good dispersion in oil phase and water phase systems, it is easy to blend and color evenly without agglomeration. It is the most mainstream and safe red inorganic pigment for high-end makeup and daily chemical coloring formulas.
