  • Cleaning agents for hard surfaces such as dishwashing detergents
  • dishwashing detergents are available to consumers in a variety of forms.
  • flowable and in particular liquid to gel detergents have become increasingly important.

  • compositions in which in particular the water content is reduced compared to conventional compositions, are increasing.
  • Compositions whose water content is as low as possible, for example less than 20% by weight, are therefore particularly desirable for the consumer.
  • organic solvents in particular polyhydric alcohols
  • 1,2-Propylene glycol and glycerol and mixtures thereof have proven to be particularly advantageous here.
  • a matrix of such organic solvents is only able to absorb sufficient amounts of a rinse aid surfactant to a limited extent, which can have a negative effect on the rinse aid performance of the product.

  • rinse aid surfactants in compositions with low water contents, for example 20% by weight or less, either leads to an unacceptable thickening of the composition and / or, in the case of the use of organic solvents, to segregation in which the rinse aid and possibly parts of the organic solvents float on the rest of the composition, causing it to become an unacceptable thickening.
  • the invention is therefore directed to a liquid, low-water to water-free automatic dishwashing detergent with a water content of 20% by weight or less, which contains at least one rinse aid surfactant, which is a nonionic surfactant, characterized in that the agent further comprises at least one hydrophobically modified acrylic polymer or copolymer selected from C 10 -C 30 alkyl modified cross-linked polyacrylate, C 10 -C 30 alkyl modified acrylate / vinyl ester copolymer and mixtures thereof, in a concentration of 0.02 Contains up to 0.8 wt .-% based on the agent, characterized in that at least one C 10 -C 30 alkyl-modified acrylate / vinyl ester copolymer is included.
