Additionally, it is a histamine liberator, and may intensify symptoms of asthma.; Ponceau 4R (also known as Food Red 7[citation needed], C.I. 16255[citation needed], Cochineal Red A[citation needed], New Coccine, Acid Red 18, SX purple[citation needed]) is a synthetic colourant that may be added to foods to induce a colour change. It is denoted by E Number E124, and has the capacity for inducing an allergic reaction. Its chemical name is trisodium salt of 1-(4-sulpho-1-napthylazo)- 2-napthol- 6,8-disulphonic acid.; Ponceau 4R is a red azo dye usually synthesized from coal tar which can be used in a variety of food products. 7-Hydroxy-8-[(4-sulfo-1-naphthalenyl)azo]-1,3-naphthalenedisulfonic acid, 9CI Acid Scarlet 3R Brilliant Ponceau 3R Brilliant Scarlet 3R C.I. 16255 C.I.
