Tetraacetylethylenediamine (TAED) is used as a bleach activator in the detergent market. TAED is only used in powder formulations due to its instability in aqueous formulations and its reaction with bleaching agents (peroxide source) under storage conditions. To address the hydrolysis issue, two imide derivatives of TAED are synthesized. Due to the increased steric hindrance close to the imide group, these two molecules exhibited improved hydrolytic stability but still had similar perhydrolytic activity compared with TAED, suggesting their potential as bleach activators.
