| Description | Allura red AC, also known as c.I. FOOD red 17 or FD & C red no. 40, Belongs to the class of organic compounds known as 2-naphthalene sulfonates. These are organic aromatic compounds that contain a naphthalene moiety that carries a sulfonic acid group at the 2-position. Naphthalene is a bicyclic compound that is made up of two fused benzene ring. It is used as a food dye and has the E number E129. Colour additive used in gelatins, puddings, custards, beverages, sauces, toppings, fruits, dairy products, bakery products, jams, jellies, condiments, meat and poultry Allura Red AC is a red azo dye that goes by several names including: Allura Red, Food Red 17, C.I. 16035, FD&C Red 40, 2-naphthalenesulfonic acid, 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfophenyl)azo)-, disodium salt, and disodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfophenyl)azo)-2-naphthalene-sulfonate. Although para-cresidine is an important reactant in the manufacture of Allura Red AC and is a known carcinogen, further studies conducted since have found no trace of para-cresidine to be present in food-grade Allura Red AC. Allura red AC is an extremely weak basic (essentially neutral) compound (based on its pKa). Allura red AC is a potentially toxic compound. Some manufacturers of Allura Red AC include: Asim Products, Sanchi Chemicals Pvt. Allura Red AC is one of many High Production Volume Chemicals. |
