Description:
Under the code KOELOS-303, Koel Colours Pvt. Ltd. supplies D&C Red No. 21, a coral red xanthene dye soluble in oil. A pigment covers through particles suspended in the base, whereas an oil-soluble dye forms a homogeneous solution with it, so the colour stays clean and transparent. Typical applications: nail polish and decorative cosmetics.
- Tetrabromofluorescein is fluorescent, giving the colour a luminous, lively look.
- Oil-soluble acid form; its sodium salt (D&C Red No. 22) is the water-soluble KOELOW-303.
- Added to the oil phase, it forms a homogeneous solution rather than a suspension.
- Gives a transparent colour with no hiding power; intensity is adjusted by concentration.
- D&C Red No. 21; declared in EU ingredient lists as CI 45380.
Applications: Nail polish, decorative cosmetics.
- Dissolve in the oil phase or in the solvent base of the product.
- Check conditions of use (product type, eye area, mucous membranes) in Annex IV of Regulation (EC) No 1223/2009.
