calcium peroxide, magnesium peroxide
News Welcome to Shangyu Jiehua Chemical, our sodium perborate is widely used for laundry and household manfucturing and formulated into multi-purpose stain remover/oxygen bleach, also the uncoated sodium percarbonate could be used for water treatment like fish farming/shrimp farming ponds. We also developed potassium monopersulfate, KMPS, Potassium Peroxymonosulfate for swimming pool spa and pool shock, which is known as oxygen shock commonlly. Both Sodium Percarbonate and Potassium Monopersulfate belong to chlorine free or non-chlorine product which is environmental friendly, belong to peroxygen salts derived from hydrogen peroxide. Calcium Peroxide and Magnesium Peroxide is used for aerobic bioremediation, oxygen release compound, our sythesis magnesium silicate adsorbent could be used for used cooking oil treatment and biodiesel dry wash, We are manufactuer of transparent Iron Oxide (pigment, dispersion), sodium hydrosulfite, 2,4-Dinitrotoluene, DNT Visit Press Room

TAED - Tetra Acetyl Ethylene Diamine

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 peroxyacid which oxidizes the stained substrate. Commercial application of this technology is found in certain fabric bleaching detergent powders that mainly incorporating tetraacetylethylenediamine (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
