Tetra
Acetyl Ethylene Diamine（TAED）Description
Many household and
personal care products are formulated with an active oxygen-releasing
material to effect removal of stain and soil.Oxygen-releasing materials have
an important limitation;their activity is extremely temperature-dependent.Temperatures
in excess of 60 DEG C are normally required to achieve any bleach
effectiveness in an aqueous wash system.Especially for cleaning fabrics,high-temperature
operation is both economically and practically
disadvantageous.Thus,bleaching activators have been applied in an object to
activate bleaching reaction at low temperatures.These activators,also known
as bleach precursors,often appear in the form of carboxylic acid esters or
amides.In an aqueous liquor,anions of hydrogen peroxide react with the ester
or amide to generate a corresponding perosyacid which oxidizes the stained
substrate.Commercial application of this technology is found in certain
fabric bleaching detergent powders that mainly incorporating tetra acetyl
ethylene diamine(TAED).TAED used for detergent industry is in granular
form,free-flowing,and has several colors(mainly white,green,blue)to choose
depending on users' choice.

Applications
TAED is typically applied in domestic laundry detergents,automatic
dish washing,bleach boosters,laundry soak treatments,to improve the washing
performance.
TAED could be applied in textile bleaching to react with
hydrogen peroxide in the bleach bath to produce a stronger oxidant.The use of
TAED as bleach activator enables bleaching at lower process temperatures and
under milder PH conditions.In pulp and paper industry,TAED is suggested to react
with hydrogen peroxide to form a pulp bleaching solution.The addition of TAed
into pulp bleaching solution results in a satisfactory bleaching effect.
