Definitions
- the present invention relates to a washing or cleaning agent which contains a water-soluble builder, the builder of a particular one Has grain size distribution, with grain sizes from 0.2 mm to below 0.4 mm are excluded.
- Builders or cobuilder systems belong to the most important substance classes for the construction of detergents or cleaning agents. You meet in the Detergents or cleaning agents perform various tasks, among others the water softening, the strengthening of the washing effect, a Graying inhibition and dirt dispersion are. Furthermore the builders are to the alkalinity necessary for the washing process contribute to a high absorption capacity for surfactants and / or others Detergent additives show, improve the effectiveness of surfactants, they can also contribute to positive properties of Deliver solid products in powder form, for example structure formation and control of the dust problem. In some cases, the different requirements with only one builder component alone not meet, so in these cases on a system of builders and Cobuilder is used.
- water-insoluble builders based on phosphorus and / or Nitrogen has come under fire for ecological reasons, whereupon a change to three-dimensionally networked, water-insoluble Builders, e.g. B. zeolites.
- water-insoluble builders however, the phenomenon of undesirable occurs to an increased extent Incrustation that required the use of cobuilders.
- polymers are often used together with zeolites Polycarboxylates, in particular copolymers based on (meth) acrylic acid and maleic acid used together with soda. They are also common Complexing agent used.
- EP-A-0 444 415 describes a detergent with 0.5 to 60% by weight a builder, 5 to 50% by weight of a surfactant and others usual washing aids, the builder being an amorphous low-water sodium disilicate with a water content of 0.3 to 6% by weight represents.
- the production of these highly dehydrated amorphous disilicates takes place in a multi-stage process, which initially involves the production of a powdered amorphous sodium silicate with a water content of 15 provides up to 23 wt .-%.
- This material is used in a rotary kiln Flue gas treated at temperatures from 250 to 500 ° C. That from the Sodium disilicate emerging from the rotary kiln is removed using a mechanical crusher crushed to grain sizes of 0.1 to 12 mm and then grind to grain sizes from 2 to 400 ⁇ m.
- Patent applications WO 96/20269 and WO 97/34977 both describe amorphous alkali silicates containing ingredients of washing or Detergents, especially ingredients (e.g. Surfactants) in liquid form.

- Brighteners of the type of substituted Diphenylstyryle be present, e.g. B.
- the agents can also do other things known, usually in washing, rinsing or cleaning agents additives used, for example small amounts of neutral Filling salts as well as colors and fragrances and opacifiers.
- the remaining washing, cleaning and other ingredients of the Detergents can be used as powder, granulate or cogranulate are, their particle size in a range of 1 to 2500 microns, is preferably from 5 to 1000 microns, or they can be used as a liquid component be added.
- the washing or cleaning agent according to the invention can be in the form of a powder Granules or as a compact, in addition, the washing or Detergent provided in the form of a pressed molded body become.
- a preferred pH range for using the builders with the one described here Grain size distribution is a range from pH 8 to pH 12.
- the enzyme performance of the proteases used is significantly improved by the builders of the particle size distribution according to the invention, so that an improvement in the washing result is also achieved in this regard.
- compositions compositions
- solubility of a detergent formulation can be assessed on the basis of the amount of residue.
- a good reference has no residues.
- the fibrous wool is one of the so-called keratins proteins essentially crosslinked by cysteine disulfide bridges represent.
- the basic building blocks of wool are amino acids that over Peptide bonds are linked together.
- the wool can be used as Substrate for the protease can be considered.
- the mining performance of the peptide-cleaving enzymes are determined gravimetrically and reflected indirectly the activity of the protease again.
- the protease activity will heavily influenced by builder performance. The better the builder acts, the faster and stronger the wool becomes from the protease decomposed.
- the test is carried out in the Linitest (laboratory tester), with eight Sample containers is equipped.
- a 10 * 10cm wool fabric is cut and labeled for each product.
- the wool is labeled with a sewn-on protease-stable Cotton fabric piece.
- the wool is washed with 200ml water (HBII) and 1g Test product washed. This process is repeated until in the Wool holes can be seen.
- HBII 200ml water
- 1g Test product washed. This process is repeated until in the Wool holes can be seen.
- After 5, 10, 15 and 20. laundry weighed dry, and the mass loss in Comparison to the respective initial value determined in%. Once a good one Differentiation is possible, washing can be stopped. In this The test was carried out on all test products 1% Everlase 12.0 T from Novo added.
- the formulations with the preferred builder fractions show a higher proteolytic activity and thus the more effective removal of Ca / Mg 2+ ions in the washing process (see table).
