TAED

TAED, Tetra Acetyl Ethylene Diamine - low temperature bleaching activator for sodium perborate. Sodium perborate/TAED oxygen bleach formulation is widely used in laundry detergent, all fabrics bleach, automatic dishwashing and stain removal/cleaning products.

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.
