Tetraacetylethylenediamine, commonly abbreviated as TAED, is an organic compound with the formula (CH3C(O))2NCH2CH2N(C(O)CH3)2. It is a white solid commonly used as a bleach activator in laundry detergents and in the production of paper pulp. TAED is synthesized through the acetylation of ethylenediamine.
==Use and mechanism of action== TAED is an important component of laundry detergents that use "active oxygen" bleaching agents. Active oxygen bleaching agents include sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulfate, and urea peroxide. These compounds release hydrogen peroxide during the wash cycle, but the release of hydrogen peroxide is low when these compounds are used in temperatures below . TAED and hydrogen peroxide react to form peroxyacetic acid, a more efficient bleach, allowing lower temperature wash cycles, around . TAED was first used in a commercial laundry detergent in 1978 (Skip by Unilever). Currently, TAED is the main bleach activator used in European laundry detergents and has an estimated annual consumption of 75 kt.
