A UK university has developed a novel formulation bleach activator based on tetra acetyl ethylene diamine (TAED) for use in solid detergents such as laundry and dishwasher products. The new formulation has higher solubility which may result in better cleaning at lower temperatures and improved environmental credentials. The university is looking for technical cooperation or license agreements with detergent manufacturers who wish to improve the performance of their products.
Tetra acetyl ethylene diamine (TAED) is used predominantly in soap powders and dishwasher tablets. Around 60% of total manufactured TAED is used in the solid detergents market and is added to detergent powders at between 2 -12% content. However, although the objective of using bleach activators is to reduce the temperature at which active bleaching species are formed, TAED has poor water solubility at room temperature. Therefore the washing process requires a higher temperature (>40 °C) and a longer washing cycle using more energy and water. The insoluble fraction of the bleach activator is drained into the waste stream causing environmental damage.
The issue of poor wettability, solubility and rate of solution becomes more challenging in the Asia-Pacific markets where there is scarcity of water and hand-wash laundering is used.
This poor water solubility also limits the commercial potential of TAED for other applications which require higher concentrations of activators such as biocidal and germicidal processes and textile, paper and pulp bleaching processes.
This UK university has developed a novel formulation of bleach activator which addresses all of the issues outlined above. The university is looking for technical cooperation or license agreements with SMEs and multinational organisations wishing to improve the performance of their detergent based products.
Novel TAED formulation with the following advantages:
- Faster to dissolve
- Twice the bleaching power at 20°C (measured by experiment)
- Potential for improved washing performance at lower temperatures = energy saving washing
- Less bleaching agent is needed reducing cost of manufacture
- Improved environmental performance due to less unreacted TAED in waste streams.
- Convenient, ambient temperature TAED based, highly effective biocides and germicides are possible
- Easy, cost effective manufacturing process
Type of partner sought - SME or multinational
Specific area of activity of the partner - Manufacture of household cleaning products. Manufacturers of ingredients for cleaning products
Task to be performed by the partner sought - Evaluate the technology and consider technical cooperation or licensing
