Product Description

Tetraacetylethylenediamine is a chemical with the chemical formula C10H16O4N2. It appears as light yellow or colored particles with a slight acetic acid taste and is slightly soluble in water.


Washing industry
As a peroxide activator, it enhances the washing efficacy, disinfection, and sterilization functions of peroxides in low-temperature water.
Bleach is an important auxiliary agent in detergents, mainly divided into two categories: oxygen-containing bleach and  containing bleach. Among numerous washing products, bleaching detergents have been favored by people since their debut in the 1970s due to their high whitening, brightening, disinfecting, sterilizing, and descaling abilities on fabrics. More than 90% of detergents in the European market contain oxygen bleach, and the sales volume of this oxygen bleach detergent in the US market is also increasing at an annual growth rate of 20% to 25%.
Among bleaching agents, oxygen-containing bleaching agents, especially peroxide bleaching agents, have more promising development prospects than traditional  containing bleaching agents. Due to its non-toxic nature,  free odor, suitability for all fibers and colored fabrics, and good compatibility with various surfactants and enzymes, oxygen-containing bleaching agents are widely welcomed by consumers. The most commonly used oxygen-containing bleaching agent is sodium perborate (SPB), accounting for approximately 75% of the total usage. Due to its high stability, sodium perborate can only effectively exert its bleaching effect when it releases primary oxygen at temperatures above 70qC, and a large amount of synthetic fibers and woolen fabrics cannot adapt to such temperatures. This requires the development of activators that can promote its bleaching effect at low temperatures.
Tetraacetylethylenediamine (TAED) is a bleaching activator that can meet this requirement. It has superior low-temperature bleaching performance, good environmental performance, and suitable price. The TAED/sodium perborate system has become the standard bleaching activator system in Europe. 75% to 80% of the bleaching detergents used in Europe use the TAED/sodium perborate system. Research has shown that in detergent formulations, when the content of tetraacetylethylenediamine reaches 1.5% to 5.0%, sodium perborate can exert its bleaching effect at room temperature.
TAED is a white or pale yellow crystal with a melting point of 149-151 ºC.
Textile printing and dyeing
The bleaching system of TAED combination is a new method recently applied to textile bleaching. It can not only lower the bleaching temperature and achieve good bleaching effect at low temperatures, but also bleach under near neutral conditions, so it can provide good protection for cellulose.
