Tetraacetylethylenediamine, commonly abbreviated as TAED, is an organic compound with the formula (CH 3 C(O)) 2 NCH 2 CH 2 N(C(O)CH 3) 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.
Persalts and bleach activators are included together in powder laundry detergents that contain bleach. In the wash, both compounds dissolve in the water. When dissolved in water, the persalt releases hydrogen peroxide (e.g. from sodium percarbonate): 2Na 2 CO 3 ∙3H 2 O 2 → 2Na 2 CO 3 + 3H 2 O 2
[8] [9] Powder Laundry Soluble Sachets were first marketed in the UK and Europe in 1998 as Soapy Sacks and shortly thereafter rebranded as Aquados and received a Millennium Award for the innovation.

Compared to TAED, which is the predominant bleach activator used in Europe, NOBS is efficient at much lower temperatures. At 20 °C NOBS is 100 times more soluble than TAED in water. [ 5 ] When attacked by the perhydroxyl anion (from hydrogen peroxide), NOBS forms peroxynonanoic acid (a peroxy acid ) and releases the leaving group sodium 4 ...
Rust, which is primarily composed of iron oxides (Fe 2 O 3), also reacts with weak acids to form soluble iron salts. The reaction can be simplified as: Fe 2 O 3 + 6H + → 2Fe + 3 + 3H 2 O. In this process, iron ions (Fe + 3) are produced along with water, making the rust easier to remove without causing damage to the underlying metal or ...
