EC NUMBER: 234-123-8

Tetraacetylethylenediamine green, commonly abbreviated as TAED Green, is an organic compound with the formula (CH3C(O))2NCH2CH2N(C(O)CH3)2. 
This white solid is commonly used as a bleach activator in laundry detergents and for paper pulp. 
TAED Green (Tetraacetylethylenediamine green) is produced by acetylation of ethylenediamine.


Use and mechanism of action
TAED Green (Tetraacetylethylenediamine green) is an important component of laundry detergents that use "active oxygen" bleaching agents. 
Active oxygen bleaching agents include sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulfate, and urea peroxide. 
TAED Green (Tetraacetylethylenediamine green) release hydrogen peroxide during the wash cycle, but Hydrogen peroxide is inefficient when used in temperatures below 60 °C (140 °F). 
TAED Green (Tetraacetylethylenediamine green) and hydrogen peroxide react to form peroxyacetic acid, a more efficient bleach, allowing lower temperature wash cycles, around 40 °C (104 °F). 
TAED Green (Tetraacetylethylenediamine green) was first used in a commercial laundry detergent in 1978 (Skip by Unilever).
Currently, TAED Green (Tetraacetylethylenediamine green) is the main bleach activator used in European laundry detergents and has an estimated annual consumption of 75 kt.


Perhydrolysis
TAED Green (Tetraacetylethylenediamine green) reacts with alkaline peroxide via the process called perhydrolysis releasing of peracetic acid. 
The first perhydrolysis gives triacetylethylenediamine (TriAED) and the second gives diacetylethylenediamine (DAED).
TAED Green (Tetraacetylethylenediamine green) typically provides only two equivalents of peracetic acid, although four are theoretically possible.
Competing with perhydrolysis, TAED Green (Tetraacetylethylenediamine green) also undergoes some hydrolysis, which is an unproductive pathway.

Preparation
TAED Green (Tetraacetylethylenediamine green) is prepared in a two-stage process from ethylenediamine and acetic anhydride. 
The process is nearly quantitative.
The acetic acid by-product is recycled as acetic anhydride.

Properties
Powdered TAED Green (Tetraacetylethylenediamine green) is stabilized by granulation with the aid of the sodium salt of carboxymethylcellulose (Na-CMC), which are sometimes additionally coated blue or green. 
Despite the relatively low solubility of TAED Green in cool water, (1 g/l at 20 °C), the granulate dissolves rapidly in the washing liquor.

The peroxyacetic acid formed has bactericidal, virucidal and fungicidal properties, thereby enabling TAED Green (Tetraacetylethylenediamine green) with percarbonate to disinfect and deodorize.

Washing industry:

Tetra Acetyl Ethylene Diamine (TAED Green) CAS 10543-57-4 might work as a peroxide activator, it can improve the washing and disinfection and bactericidal functions of peroxide in low-temperature water.

Tetra Acetyl Ethylene Diamine (TAED Green) CAS 10543-57-4 can also help in Bleaching agent, which is an important assistant in detergent. There are two main types of bleaching agents, oxygen bleaching agent and chlorine bleaching agent. 
Among many detergents, bleaching detergents have high whitening, brightening, disinfection, sterilization and scale removal effects on fabrics. 
Therefore, since the advent of bleaching detergents in the 1970s, they have been widely favoured by people. 
More than 90% of detergents in the European market are added with the oxygen-containing bleaching agents. 
Sales of this kind of oxygen-containing bleaching detergent in the American market are also increasing at an annual growth rate of 20%-25%.

Among bleaching agents, oxygen-containing bleaching agents, especially peroxide bleaching agents, have more development prospects than traditional chlorine-containing bleaching agents. 
The oxygen-containing bleaching agent is non-toxic, chlorine-free, suitable for all fibres and non-ferrous fabrics, and has good compatibility with various surfactants and enzymes, so it is more popular among consumers. 
Sodium perborate (SPB) is the most widely used oxygen bleaching agent, accounting for about 75% of the total use. 
Because of the high stability of sodium perborate, the bleaching effect of sodium perborate can be effectively achieved only when the initial ecological oxygen is released above 70 QC, but a large number of synthetic fibres and wool fabrics can not adapt to this temperature. It is necessary to develop an activator that can promote its bleaching effect at low temperatures.

Tetraacetylethylenediamine green or Tetra Acetyl Ethylene Diamine (TAED Green) is the bleaching activator that can meet this requirement. 
It has excellent low-temperature bleaching performance, good environmental protection performance and a suitable price. 
Tetra Acetyl Ethylene Diamine (TAED Green)/sodium perborate system has become the European standard bleaching activator system. 
Among the bleaching detergents used in Europe, 75%-80% use Tetra Acetyl Ethylene Diamine (TAED Green)/perboric acid. Sodium system. 
Some studies have shown that when the content of tetraacetylethylenediamine reaches 1.5%-5.0% in detergent formulation, sodium perborate can play its bleaching effect at room temperature.

Tetra Acetyl Ethylene Diamine (TAED Green) is a white or yellowish crystal. 
Its structure is shown in the figure. 
The melting point is 149 - 151 C.

Textile printing and dyeing:

The hydrogen peroxide/ Tetra Acetyl Ethylene Diamine (TAED Green) bleaching system is a new method for textile bleaching. 
It can not only reduce the bleaching temperature, obtains a good bleaching effect at low temperatures, but also bleach under near-neutral conditions, so it can play a good protective role on cellulose.

1. As a peroxide activator, it improves the washing efficiency and disinfection function of peroxide in low-temperature water.
2. It has excellent performance in low temperature bleaching and environmental protection with suitable price.
3. In detergents, when the content of tetraacetylethylenediamine reaches 1.5% to 5.0%, the sodium perborate can exert its bleaching effect at normal temperature.
4. The combination of hydrogen peroxide and TAED Green is a new method for textile bleaching. It not only reduces the bleaching temperature, but also achieves good bleaching effect at low temperatures.

T.A.E.D. is a low temperature oxygen bleaching activator, widely used in:
- Detergent industry
- Textile and dyeing industry


Function in detergent industry:
Bleaching agent is an important ingredient in detergent system with its properties of whitening, brightening, cleaning and sterilizing effect. In various detergent products, there are mainly 2 types of bleaching agent:
1), Oxygen series;
2), Chloride series.

Comparing chloride series bleach agent, oxygen series’ advantages are:
- Non toxic;
- No chloride odor;
- Suitable to all the fiber and colorful fiber;
- Better compatibility with various surfactants and enzymes.
So oxygen series bleaching agent is more popular in fast-consuming detergents. But there is also one disadvantage for oxygen series bleaching agent.
The 2 main oxygen series bleaching agent are:
- Sodium Percarbonate (SPC);
- Sodium Perborate (SPB).
When sodium perborate is used in detergent system, it’s bleaching effect can only be mostly released when the water temperature reaches 60℃, while this high temperature is not only energy consuming but also can harm some fabrics. To solve this problem, there are 2 solutions:
1), Using Sodium percarbonate (SPC) to replace sodium perborate (SPB),
2), Adding T.A.E.D, to activate Sodium perborate under the water temperature 30~60 ℃.
