Azodicarbonamide is a dough conditioner that exists as a yellow to
orange-red crystalline powder practically insoluble in water. it is
used in aging and bleaching cereal flour to produce a more manage-
able dough and a lighter, more voluminous loaf of bread. it is used
in bread flours and bread as a dough conditioner. it can be used with
the oxidizing agent potassium bromate. a typical use level is less
than 45 ppm. | [CAS DataBase Reference]

| Hazard Information | Back Directory | [General Description]
A yellow to orange powder. Insoluble in water and common solvents. Soluble in dimethyl sulfoxide. Nontoxic. | [Reactivity Profile]
AZODICARBONAMIDE(123-77-3) is easily ignited and burns rapidly. Confined samples show a high rate of pressure rise during thermal decomposition, which produces carbon monoxide and nitrogen. Sensitive to temperatures exceeding 122°F. May be sensitive to exposure to light. Stable in bulk when stored for two weeks at temperatures up to 140°F. Slightly unstable in water suspension (showed1.3% decomposition at 2 mg/mL over a two-week period at room temperature in the light but no decomposition at 41°F over a two-week period in the dark . Reacts with hot water to give nitrogen, carbon monoxide, and ammonia [Hawley]. Decomposes in hot hydrochloric acid. Incompatible with strong acids and bases, and with compounds of metals. | [Air & Water Reactions]
Highly flammable. Water insoluble. Dust may form an explosive mixture in air. | [Health Hazard]
Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce irritating, toxic and/or corrosive gases. Runoff from fire control may cause pollution. | [Fire Hazard]
Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. May be ignited by heat, sparks or flames. Some may decompose explosively when heated or involved in a fire. May burn violently. Decomposition may be self-accelerating and produce large amounts of gases. Vapors or dust may form explosive mixtures with air. | [Chemical Properties]

| Questions And Answer | Back Directory | [Description]
Azodicarbonamide is a synthetic chemical that exists at ambient temperature as a yellow-orange crystalline solid. Azodicarbonamide is mainly used as a blowing agent in the rubber and plastics industries in the expansion of a wide range of polymers, including polyvinyl chloride, polyolefins, and natural/synthetic rubbers. Azodicarbonamide is also used as a food additive, such as an aging and bleaching ingredient in cereal flour and as a dough conditioner in bread baking.
