What is Tetraacetylethylenediamine?

Tetraacetylethylenediamine (TAED) is an organic compound appearing as a white, free-flowing crystalline powder with a slight acetic odor. It is sparingly soluble in cold water but hydrolyzes in warm water. TAED is primarily used as a bleach activator in detergent formulations, where it significantly enhances the bleaching efficiency of peroxygen-based bleaches at lower temperatures. It is biodegradable and environmentally compatible.

Application:

Bleach activator: TAED's primary use is to activate oxygen-based bleaches (like sodium perborate) at low temperatures

Laundry detergents: It's a key ingredient in many laundry detergents, allowing them to clean and brighten clothes effectively without requiring high temperatures.  

Dishwashing products: TAED is found in automatic dishwasher detergents as well.  

Industrial bleaching: It is used in the bleaching of paper pulp and textiles.  

Biocide: It is also used in applications such as disinfecting medical instruments and in poultry and swine facilities.  

Other applications: TAED can be used in cosmetics, personal care products, and leather tanning.

Safety Profile:

Tetraacetylethylenediamine is generally considered to have low toxicity. May cause mild eye irritation. Inhalation of dust may cause respiratory irritation. Use appropriate personal protective equipment including dust mask and safety glasses when handling. The substance is readily biodegradable and has low environmental impact. For detailed safety information, consult the full Safety Data Sheet (SDS).

Storage Requirements:

Store in a cool, dry, well-ventilated area away from direct sunlight. Keep containers tightly closed and sealed. Maintain storage temperature below 30°C. Relative humidity below 65% recommended. Store away from strong oxidizing agents and acids.

Transport & Packaging:

Tetraacetylethylenediamine is packaged in paper-plastic composite bags with inner polyethylene liner (25 kg net weight per bag). Transport as non-hazardous material under normal conditions. Ensure containers are properly sealed and protected from moisture during transportation. Store away from incompatible materials.
