Combining TAED (Tetraacetylethylenediamine) with sodium percarbonate creates a powerful duo that significantly enhances bleaching and stain removal capabilities, particularly at lower temperatures. This combination outperforms using sodium percarbonate alone due to the superior oxidative properties of peracetic acid produced during the reaction. Let’s explore why this partnership is a game-changer in modern detergents.

Perfect partner: TAED (Tetraacetylethylenediamine) and Sodium Percarbonate

Using TAED (Tetraacetylethylenediamine) in combination with sodium percarbonate is better than using sodium percarbonate alone primarily because TAED significantly enhances the bleaching and stain-removal capabilities of sodium percarbonate, especially at lower temperatures. Here are the reasons:

1、Improved Bleaching Efficiency: Sodium percarbonate decomposes in water to produce hydrogen peroxide (H₂O₂) and sodium carbonate. While hydrogen peroxide is an effective bleaching agent, its efficiency is limited at lower temperatures. TAED reacts with hydrogen peroxide to produce peracetic acid (PAA), which is a much stronger oxidizing agent, thereby enhancing the bleaching and stain removal efficiency.


2、Enhanced Low-Temperature Performance: Peracetic acid is effective even at low temperatures, making the combination of TAED and sodium percarbonate powerful for stain removal and bleaching in cold water washes. This is important for energy savings and fabric care.

3、Reduced Reaction Time: The reaction of TAED with hydrogen peroxide to form peracetic acid allows for a quicker action on stains, reducing the time needed for effective bleaching. This is beneficial for improving washing efficiency and saving time.

4、Increased Disinfecting Power: Peracetic acid is not only a strong bleaching agent but also a potent disinfectant, capable of killing bacteria, fungi, and viruses. Thus, the combination of TAED and sodium percarbonate provides more thorough cleaning and disinfection.

5、Stability and Safety: Using hydrogen peroxide directly can pose storage and handling challenges, whereas sodium percarbonate in solid form is more stable and safer to use. The activation by TAED to produce more effective peracetic acid happens during the washing process.

For these reasons, the combination of TAED and sodium percarbonate is more effective than using sodium percarbonate alone, particularly in low-temperature washing and scenarios requiring strong bleaching, stain removal, and disinfecting power. This combination is widely used in modern detergents, enhancing their performance and user satisfaction.

Reaction between TAED and Sodium Percarbonate

TAED (Tetraacetylethylenediamine) reacts with sodium percarbonate to produce peracetic acid (PAA), a potent oxidizing agent widely used for cleaning and disinfection. The reaction mechanism is as follows:

1、Reaction of TAED with Sodium Percarbonate: During the washing process, TAED reacts with sodium percarbonate (Na2CO3·1.5H2O2). Sodium percarbonate decomposes in water to produce hydrogen peroxide (H2O2) and sodium carbonate (Na2CO3).

2、Formation of Peracetic Acid: TAED reacts further with hydrogen peroxide to generate peracetic acid and acetic acid (CH3COOH).

The chemical reaction equation is:


Where C6H10O4N2 is TAED, H2O2 is hydrogen peroxide, C2H4O3 is peracetic acid, and C2H4O2N2 is a byproduct.

Peracetic acid is a strong oxidizing agent that can effectively break down and remove stubborn stains, while also providing a disinfecting effect. This reaction process enhances the cleaning power of detergents, especially in low-temperature environments.

In summary, the reaction between TAED and sodium percarbonate produces peracetic acid, which enhances the performance of detergents, making them more effective at stain removal and disinfection.

Reaction of Peroxyacetic Acid with stubborn stains

Peracetic acid (PAA) is a powerful oxidizing agent with excellent bleaching and disinfecting capabilities, making it effective at removing stubborn stains. Its mechanism of action includes the following:

1、Oxidation Reaction: Peracetic acid’s strong oxidative properties enable it to break down the chemical structure of organic stains. For example, peracetic acid can oxidize pigment molecules, causing them to lose their color, thus achieving a bleaching effect. It can oxidize stubborn organic stains like tea, coffee, and red wine, making them colorless or soluble in water.

2、Breaking Down Proteins and Fats: Peracetic acid can denature or decompose protein and fat molecules through oxidation. For instance, it can oxidize thiol groups (-SH) in proteins to disulfide bonds (-S-S-), leading to protein denaturation, making them easier to wash away.

3、Decomposing Biofilms and Microorganisms: Peracetic acid effectively kills bacteria, fungi, and viruses by breaking down their cell walls and membranes. Its strong oxidative properties allow it to penetrate and disrupt the cellular structure of microorganisms, rendering them inactive.

4、Generating Oxygen Bubbles for Cleaning: The decomposition of peracetic acid generates oxygen bubbles, which can create a mechanical action on stain and fabric surfaces, helping to loosen and remove stains.


In summary, peracetic acid, through its strong oxidative properties, effectively breaks down and removes stubborn organic stains, proteins, and fats, while also providing a disinfecting action, making it a crucial component in detergents and cleaners.

In summary, the combination of TAED and sodium percarbonate produces peracetic acid, significantly boosting the cleaning power of detergents. This partnership not only improves stain removal and bleaching efficiency but also offers strong disinfecting properties, even at low temperatures. By leveraging the benefits of this powerful duo, modern detergents achieve superior performance and user satisfaction.
