- 25 detergents of this type are usually dosed with 2.5 to 7 g / 1.
- Phosphate-reduced compact detergents have the following composition, for example: 30
- Detergents of this type are usually dosed with 2.5 to 7 g / 1.
- Phosphate-free compact detergents have the following composition, for example:
- Aminopolycarboxylates or mixtures thereof 5 to 35% surfactants 0.5 to 6% compounds la or Ib
- Detergents of this type are usually dosed with 2.5 to 7 g / 1.
- the textile detergent formulation according to the invention is outstandingly suitable for washing textiles in households and businesses under washing conditions, such as are common in Europe, e.g. with a high detergent dosage and with low (short) liquor ratios. Therefore, the use of the textile detergent formulation according to the invention in a dosage of more than 2 g per liter of wash liquor, preferably in a dosage of 2.5 to 15 g per liter of wash liquor, for washing textiles in household and commercial use is the subject of the present invention Invention. This use is preferably made with a liquor ratio of textile material to wash liquor of 1:10 to 1: 2, preferably of 1: 5 to 1: 3.
- a significantly better bleaching effect is achieved in particular with the textile detergent formulation according to the invention, in particular also at low washing temperatures of 20 to 60 ° C., this is shown by corresponding comparisons with the commonly used bleach activator TAED.
- the textile detergent formulation according to the invention is largely insensitive to hard water, in particular to hard water above 2 mmol Ca 2 2 / l.
- the textile detergent formulation according to the invention achieves high levels of active oxygen in the wash liquor, which contributes to the good washing result.
- Usual active oxygen contents here are 100 to 320 ppm, in particular 140 to 280 ppm.
- Table 1 Compositions of textile detergent formulations according to the invention (in% by weight)
- Table 2 Compositions of textile detergent formulations according to the invention (in% by weight)
- Soil release polymer 1 graft polymer of vinyl acetate on polyethylene glycol with a molecular weight of 6,000
- Soil release polymer 2 polyethylene terephthalate / polyoxyethylene terephthalate with a molecular weight of 8000
- Dequest ® 2046 ethylenediamine-N, NN ', N' - tetra (methylenephosphonate)
- the color strength of the test fabric was measured photometrically.
- the reflectance values measured at the individual test tissues at 16 wavelengths in the range from 400 to 700 nm at a distance of 20 nm were converted according to the method described in A. Kud, Seifen, ⁇ le, Fette, Wwachs 119, pp. 590-594 (1993) the respective color strengths of the test soils before and after washing are determined and the absolute bleaching action A abS n% is calculated therefrom.
