Sodium percarbonate and Tetraacetylethylenediamine (TAED) which are the bleaching agents in our supply program whiten the textile fiber through an oxidative process. This includes degradation of the undesired colors by destruction and/or modification of the chromophoric groups in the substrate in parallel with degradation of the molecules that impart color into smaller soluble units that are removed from the fiber in the bleaching process.

Sodium percarbonate, which contains about 13% of active oxygen, can be generally used as alternative to sodium perborates. The tendency towards decreasing washing temperatures, which decrease the effectiveness of peroxide-based bleaches has stimulated research towards activators to improve bleaching effectiveness at low temperatures.

Specifically in Europe, tetraacetylethylenediamine (TAED) is widely used for this purpose. TAED undergoes perhydrolysis reaction with peroxides generating two moles of peracid as an active bleaching chemical and one mole of diecitylethylenediamine per mole of imide.
