| Description | FD & C Red No. 40 is principally the disodium salt of 6-hydroxy5-[(2-methoxy-5-methyl-4-sulfophenyl)azo]2-napthalenesulfonic acid. The colorant is a red powder that dissolves in water to give a solution red at neutrality and in acid and dark red in base. It is slightly soluble in 95% ethanol. FD & C Red No. 40 is used in gelatins, puddings, custards, alcoholic and nonalcoholic beveraes, sauces, toppings, candy sugars, frostings, fruits, juices, dairy products, bakery products, jams, jellies, condiments, meat, and poultry. FD & C Red No. 40 is also used for coloring drugs and cosmetics.1. |
| Chemical Properties | Red powder |
| Uses | Color additive in foods, drugs and cosmetics. It is used as a food dye and has the E number E129. The study found increased levels of hyperactivity and attention deficit hyperactivity disorder and lower IQs were observed in children consuming the chemicals. It is banned in Denmark, Belgium, France, Switzerland, Sweden. |
| Uses | Allura Red AC (FD&C Red #40) is a colorant. It has good stability to ph changes from ph 3 to 8, showing no appreciable change. It has excellent solubility in water with a solubility of 22 g/100 ml at 25°c. It has very good stability to light, fair to poor stability to oxidation, good stability to heat, and shows no appreciable change in stability in 10% sugar systems. It has a yellowish-red hue and has a very good tinctorial strength. It has very good compatibility with food components and is used in beverages, desserts, candy, confections, cereals, and ice cream. The common name is allura? red ac. |
| Preparation | 4-Amino-5-methoxy-2-methylbenzenesulfonic acid diazo, and 6-Hydroxynaphthalene-2-sulfonic acid?coupling. |
| Definition | ChEBI: Allura red AC is a naphthalenesulfonic acid. |
| Flammability and Explosibility | Non flammable |
| Properties and Applications | Yellow light red to red. Deep red powder, odourless. Soluble in water, 0.1% water solution is what with red, can dissolve in glycerin and propylene glycol, slightly soluble in ethanol, insoluble in grease. Has the characteristics of acid dyes. In 100ml 0.2 mol/ L ammonium acetate solution contains 0.001g samples, the maximum absorption wavelength for 499 + 2 nm. Resistance to light sex, heat resistance, the salt resistance, resistance to acidic sex is strong. To such as citric acid, tartaric acid stability. Good alkali resistance and oxidizing is good, the sulfur dioxide well tolerated. |
