Beschreibung
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

Reaktivit?t anzeigen
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.
Brandgefahr
Flash point data for Food Yellow 3 are not available; however, Food Yellow 3 is probably combustible.
Sicherheitsprofil
Low toxicity by
ingestion and intraperitoneal routes.
Mutation data reported. When heated to
decomposition it emits very toxic fumes of
NOx and SOx.
