Indigo carmine, or 5,5-indigodisulfonic acid sodium salt, is an organic salt derived from indigo by aromatic sulfonation, which renders the compound soluble in water. It is approved for use as a food colorant in the U.S and E.U. It has the E number E132. It is also a pH indicator. Indigo carmine in a 0.2% aqueous solution is blue at pH 11.4 and yellow at 13.0. Indigo carmine is also a redox indicator, turning yellow upon reduction. Another use is as a dissolved ozone indicator through the conversion to isatin-5-sulfonic acid. This reaction has been shown not to be specific to ozone, however: it also detects superoxide, an important distinction in cell physiology. It is also used as a dye in the manufacturing of capsules.

Orange-red colour used in sweets, drinks and condiments, medications and cosmetics, A red synthetic azo dye introduced in the early eighties to replace Amaranth, E123, in the United States of America where E123 is prohibited E number: E129 (colors) Chemical formula: C18H14N2Na2O8S2 CAS Number: 25956-17-6
Amaranth, FD&C Red No. 2, E123, C.I. Food Red 9, Acid Red 27, Azorubin S, or C.I. 16185 is a modified red azo dye used as a food dye and to color cosmetics. The name was taken from amaranth grain, a plant distinguished by its red color and edible protein-rich seeds. Amaranth is an anionic dye. It can be applied to natural and synthetic fibers, leather, paper, and phenol-formaldehyde resins. As a food additive, it has E number E123. Amaranth usually comes as a trisodium salt. It has the appearance of reddish-brown, dark red to purple water-soluble powder that decomposes at 120 �°C without melting. Its water solution has an absorption maximum of about 520 nm. Like all azo dyes, Amaranth was, during the middle of the 20th century, made from coal tar; modern synthetics are more likely to be made from petroleum byproducts.
