- the present invention relates to a process for the preparation of formulations according to the invention and their use as or for the production of dishwashing agents, in particular dishwasher detergents for automatic dishwashing.
- Dishwashing detergents have many requirements to fulfill. So they have to thoroughly clean the dishes, they should have no harmful or potentially harmful substances in the wastewater, they should allow the draining and drying of the water from the dishes, and they should not cause problems when operating the dishwasher. Finally, they should not lead to aesthetically undesirable consequences on the good to be cleaned.
- Glass corrosion is caused not only by mechanical effects, for example, by juxtaposition of glasses or mechanical contact of the glasses with parts of the dishwasher, but is mainly promoted by chemical influences. For example, certain ions can be released from the glass by repeated mechanical cleaning, adversely altering the optical and thus the aesthetic properties.
- Glass corrosion has several effects. On the one hand, one can observe the formation of microscopically fine cracks, which are noticeable in the form of lines. On the other hand, one can often observe a general cloudiness, for example a roughening, which makes the glass in question look unaesthetic. Overall, such effects are also subdivided into iridescent discoloration, scoring and surface and annular opacities.
