Azodicarbonamide Uses

Azodicarbonamide (CAS NO.123-77-3) is used in food industry as a food additive, a flour bleaching agent and improving agent. The principal use of Azodicarbonamide(123-77-3) is in the production of foamed plastics. The thermal decomposition of azodicarbonamide results in the evolution of nitrogen, carbon monoxide , carbon dioxide , and ammonia gases which are trapped in the polymer as bubbles to form a foamed article. Common examples of this application are window and door gaskets, padded floor mats, gym/exercise mats, shoe soles etc...

Azodicarbonamide Safety Profile

Hazard Codes: Harmful Xn
Risk Statements: 42-44
R42: May cause sensitization by inhalation
R44: Risk of explosion if heated under confinement
Safety Statements: 22-24-37
S22: Do not breathe dust
S24: Avoid contact with skin
S37: Wear suitable gloves
RIDADR: UN 3242 4.1/PG 2

RTECS: LQ1040000
HazardClass: 4.1
PackingGroup: II
Azodicarbonamide (CAS NO.123-77-3) is a respiratory sensitiser (a possible cause of asthma) and it should be labeled with "May cause sensitisation by inhalation." Azodicarbonamide (CAS NO.123-77-3) may cause an allergic reaction in those sensitive to other azo compounds (such as food dyes). The consumption of azodicarbonamide may also heighten an allergic reaction to other ingredients in a food. Panera Bread uses Azodicarbonamide in their bagels. It should be noted that during the bread baking process azodicarbonamide is completely decomposed into gasses (carbon dioxide, carbon monoxide, nitrogen, and ammonia) and therefore is never eaten.
