Azodicarbonamide, ADCA, ACA, ADA, or azo(bis)formamide, is a chemical compound with the molecular formula C₂H₄O₂N₄. It is a yellow to orange-red, odorless, crystalline powder. It is sometimes called "the yoga mat chemical" because of widespread use in foamed plastics. It was first described by John Bryden in 1959.
