Sunset Yellow FCF Chemical Properties,Uses,Production
Description
FD & C Yellow No. 6 is principally the disodium salt of 6-hydroxy5-[(4-sulfophenyl)azo]-2-napthalenesulfonic acid. The trisodiumsalt of 3-hydroxy-4-[(4-sulfophenyl)azo]-2,7-napthal-enedisul- fonic acid may be added in small amounts.
The colorant is an orange powder that dissolves in water to give a solution yellow-orange at neutrality or in acid and red-brown in base. When dissolved in concentrated sulfuric acid, it yields an orange solution that turns yellow when diluted with water. It is slightly soluble in 95% ethanol.
FD & C Yellow No. 6 is used in various food items including dessert powders, cereals, bakery goods, snack foods, confectionery products, maraschino cherries, sausage, ice cream, sherbet, dairy products, and beverages. It is also used in cosmetics, ingested and externally applied drugs and dietary supplements.1

Definition
ChEBI: Sunset Yellow FCF is an organic molecular entity.
Preparation
4-Aminobenzenesulfonic aciddiazo, and 6-Hydroxynaphthalene-2-sulfonic acidcoupling.
General Description
Orange-red crystals or a red powder.
Air & Water Reactions
Azo dyes can be explosive when suspended in air at specific concentrations. Soluble in water.
Reactivity Profile
Food Yellow 3 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
Health Hazard
SYMPTOMS: It can cause enlargement of the caecum and weight loss.
Fire Hazard
Flash point data for Food Yellow 3 are not available; however, Food Yellow 3 is probably combustible.
Flammability and Explosibility
Non flammable
Safety Profile
Low toxicity by ingestion and intraperitoneal routes. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and SOx.
Properties and Applications
red light yellow to colourful yellow orange. Soluble in water for yellow light red clarified solution, slightly soluble in ethanol, insoluble in grease. The strong sulfuric acid in red for orange, yellow as diluted. Dye with strong hydrochloric acid solution of color; Add thick sodium hydroxide solution is palm red light. Has the characteristics of acid dyes, can make the animal fiber direct shading.
