#1732764875008300-434: Is different from Wikidata All article disambiguation pages All disambiguation pages Azodicarbonamide Azodicarbonamide , ADCA , ACA , ADA, or azo( bis )formamide , is a chemical compound with the molecular formula C 2 H 4 O 2 N 4 . It is a yellow to orange-red, odorless, crystalline powder. It is sometimes called a 'yoga mat' chemical because of its widespread use in foamed plastics. It
325-482: Is motivated by studies of semicarbazide , a side product of ADA use in packaging, showing "weak carcinogenic activity in laboratory animals" but inconclusive as to carcinogenic risk to humans. The EU banned ADA in food containers despite an EFSA report considering such exposure "not a concern" due to low levels produced. The FDA considers ADA to be safe in permissible concentrations. As of February, 2021, in contrast to direct competitors like Wendy's that have phased out
350-419: The 1980s; the first mats were cut from carpet underlay. As a food additive , azodicarbonamide is used as a flour bleaching agent and a dough conditioner . It reacts with moist flour as an oxidizing agent. The main reaction product is biurea , which is stable during baking. Secondary reaction products include semicarbazide and ethyl carbamate . It is known by the E number E927 . Many restaurants in

425-561: The European Union since August 2005 for the manufacture of plastic articles that are intended to come into direct contact with food. In the United States, azodicarbonamide has a generally recognized as safe (GRAS) status and is allowed to be added to flour at levels up to 45 ppm . However, use in products intended for human consumption is in decline under pressure of the public opinion. In 2014, amid public discomfort with
450-564: The US fast food industry removed the additive in response to negative publicity. In a 1999 report, the World Health Organization has linked exposure to azodicarbonamide at workplaces where it is manufactured or handled in raw form to "respiratory issues, allergies and asthma". The available data are restricted to these occupational environments. Exposure of the general public to azodicarbonamide could not be evaluated because of
475-520: The dual uses of azodicarbonamide, the sandwich franchise Subway and hamburger franchise Wendy's announced that they would no longer use it as a dough conditioner. As of February 2014, the Center for Science in the Public Interest stated azodicarbonamide "has been poorly tested" and advocates for reducing the amount of azodicarbonamide that is allowed to be used in food.

525-523: The lack of available data. The WHO concluded, "The level of risk is uncertain; hence, exposure levels should be reduced as much as possible". In the UK , the Health and Safety Executive has identified azodicarbonamide as a respiratory sensitizer (a possible cause of asthma ) in workplace settings and determined that containers of it should be labeled with "May cause sensitisation by inhalation." Azodicarbonamide

#1732764875008550-421: The polymer as bubbles to form a foamed article. Azodicarbonamide is used in plastics, synthetic leather, and other industries and can be pure or modified. Modification affects the reaction temperatures. Pure azodicarbonamide generally reacts around 200 °C. In the plastic, leather, and other industries, modified azodicarbonamide (average decomposition temperature 170 °C) contains additives that accelerate
575-426: The reaction or react at lower temperatures. An example of the use of azodicarbonamide as a blowing agent is found in the manufacture of vinyl (PVC) and EVA-PE foams , where it forms bubbles upon breaking down into gas at high temperature. Vinyl foam is springy and does not slip on smooth surfaces. It is useful for carpet underlay and floor mats . Commercial yoga mats made of vinyl foam have been available since
600-600: Was added to the REACH Regulation candidate Substances of Very High Concern list in 2012, for its respiratory sensitizing properties. In some jurisdictions, the use of azodicarbonamide as a flour bleaching agent has been phased out. For example, it is no longer authorized for use in Australia and the European Union as a food additive. Azodicarbonamide as a blowing agent in plastics has been banned in
625-485: Was first described by John Bryden in 1959. It is prepared in two steps via treatment of urea with hydrazine to form biurea , as described in this idealized equation: Oxidation with chlorine or chromic acid yields azodicarbonamide: The principal use of azodicarbonamide is in the production of foamed plastics as a blowing agent . The thermal decomposition of azodicarbonamide produces nitrogen, carbon monoxide, carbon dioxide, and ammonia gases, which are trapped in
