Many household and personal care products
are formulated with an actioxygen-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.
As the most commercialized low temperature bleaching
activator, 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. 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. |
