Definitions
- the present patent application relates to a process for the production of pasty, anhydrous or low-water Detergents and cleaning agents that, despite their insoluble content, are stable to sedimentation.
- Paste-like detergents and cleaning agents have advantages with regard to them easy handling and relatively easy to manufacture on the apparatus side, with a further advantage is that you have a relatively wide margin with regard to the recipe components and thus the composition can largely adapt to specific washing requirements.
- Differentiate in this regard are pasty detergents from pourable detergents, which, if no suitable measures are taken will have undesirable sedimentation if they contain insoluble components.
- active oxygen compounds In addition, as a rule, such detergents do not have an application component in the formulation acceptable depletion of active oxygen. This is caused by unbound water, by multifunctional alcohols (preferably with adjacent OH groups or also with residual monomer components in polyols). Sedimentation-stable pasty detergents behave more favorably in this regard.
- the object of the present invention was therefore to provide a method for simple manufacture paste-like detergents that are sedimentation-stable despite the content of insoluble components.
