Definitions
- the undesired strong foaming of detergents can be suppressed by adding foam-suppressing polydimethylsiloxanes. It is also known that the state of distribution of the siloxanes in the detergent plays an important role in the effectiveness. If the siloxanes are added to the slurry before the atomization drying, this results in a homogeneous distribution state in which there is also no impairment of the washing power, but at the same time the foam-suppressing effect in some cases drops considerably.
- DE-AS 23 38 468 describes a detergent in which the siloxane is incorporated into a carrier substance which is free from surface-active substances and is impenetrable to detergents.

- Spray drying can be carried out in a manner known per se by spraying the slurry via nozzles into a drying tower into which gas or air heated to 110 to 300 ° C. is introduced in cocurrent or countercurrent.
- the spray drying is carried out so that the dried powder component (A) preferably has a liter weight of 300 to 700 g and thus in the order of magnitude of a spray-dried detergent, which largely excludes segregation when the detergent is later transported.
- component (A) can also be prepared by spraying an aqueous sodium sulfate solution, heated to temperatures above 32.4 ° C., in which the rest Components are dispersed or dissolved and their water content is such that in the subsequent spraying, with simultaneous cooling to temperatures below 32.4 ° C., the water is completely bound to sodium sulfate decahydrate (Glauber's salt) while the spray material solidifies.

- the powder detergents produced in the manner indicated are characterized by favorable foaming behavior. It is advantageous that the foam-suppressing effect of the siloxanes does not suffer any appreciable losses in the production process according to the invention or during storage, but that on the other hand, when the agents are used, there is no graying of the tissues or no exposure of the washing machine parts to a siloxane film which is very difficult to remove .
- the spraying was carried out in a spray tower which was equipped with 3 spray nozzles and in which the dry air heated to 220 ° C. was passed in countercurrent.

- the foam behavior was tested in a commercial washing machine having a horizontally arranged drum at temperatures of 60 0 and 95 ° C after 10 days of storage of the mixture. For this purpose, the machine was loaded with 3.5 kg of clean laundry (cotton). The detergent concentration was 7.5 g and the water hardness was 16 ° dH. The respective foam height was checked through the sight glass of the front door and graded as follows:
- the siloxane-K-silica mixture was added directly to the wash liquor.
- composition A 2 containing 50% by weight of water was added to a detergent slurry containing 35% by weight of water, the solids composition of which corresponded to that of component (B) in the examples above. After homogenization, the slurry was spray-dried in the customary manner and the spray product was mixed with 20% by weight sodium perborate.
- the respective proportions of siloxane are shown in Table 4.
- 5 wt .-% polydimethylsiloxane were mixed according to the working method according to DE-OS 23 38 468, Example 1 with 5 wt .-% silica and 40 wt .-% of an ethoxylated tallow alcohol (25 EO) at 50 ° C and on a fluidized Sprayed bed of 50 wt .-% sodium sulfate.
- the granules obtained were mixed with the spray-dried detergent component (B) and 20% sodium perborate according to the examples above. After a standing time of 10 days, the mixtures were examined for foam behavior and graying properties in accordance with the composition given in Table 4.
- the foaming behavior of the test samples and the formulation according to Example 3 was carried out in a drum washing machine charged with 3.5 kg of clean filling laundry at 95 ° C., a detergent concentration of 7.5 g / 1 using water at 3 ° dH (that is, under difficult conditions) checked. It was not the foam height (which is less suitable for an exact comparison), but the volume of the over-foamed washing liquor (so-called liquor loss) that was measured.
- liquor loss the volume of the over-foamed washing liquor
- the tests were carried out in a drum washing machine at a temperature of 60 ° C, a detergent concentration of 7.5 g / 1 and a water hardness of 16 ° dH.
