Local:
CARMOISINE is a synthetic acid dye containing both NN and CC chromophore groups (pyrazolone dye). It is a red dye; soluble in water; melting point >300 C; used in coloring food, cosmetics and meications (C.I. Food Red 3).  But it is banned by the FDA due to carcinogen suspect. The chemical designation is 4-hydroxy-3-(4-sulfonato-1- naphthylazo) naphthalene-1-sulfonate, disodium salt. Acid dyes are water-soluble dyes employed mostly in the form of sodium salts of the sulfonic or carboxylic acids. They are anionic which attach strongly to cationic groups in the fibre directly. They can be applicable to all kind of natural fibres like wool, cotton and silk as well as to synthetics like polyesters, acrylic and rayon. But they are not substantive to cellulosic fibres. They are also used in paints, inks, plastics and leather.
