Definitions
- the present invention relates to the use of selected surface-active substances, alone or in combination, for use in detergents and, in particular, in dishwashing detergents for automatic dishwashing.
- the cleaning of hard surfaces and especially the washing of dishes makes special demands on the cleaner used. This is especially true for automatic dishwashing.
- the three components of the mechanical system are cleaners, rinse aids and regeneration salts for water softening.
- the central tasks of the main component cleaners are the soil release, the dirt dispersion, the binding of residual water hardness and the corrosion inhibition.
- An essential parameter for dishwashing is the rinse aid performance. It determines the amount of i5 deposits on the dishes after they have been rinsed.
- the deposits are essentially mineral compounds, in particular Ca and / or Mg salts, but also surfactant residues. However, lime mainly leads to undesirable deposits for the user. To reduce the proportion of these deposits contain common dishwashing detergents, especially those for automatic
- rinse aid 20 dishwashing, usually so-called rinse aid.
- Commercially available rinse aids are usually mixtures of low-foaming nonionic surfactants, typically fatty alcohol polyethylene / polypropylene glycol ethers, solubilizers (eg cumene sulfonate), organic acids (eg citric acid) and solvents (eg ethanol) in it, the interfacial tension of the water so too
- solubilizers eg cumene sulfonate
- organic acids eg citric acid
- solvents eg ethanol
- combination products are increasingly being used, in which the various functions, such as cleaning, rinsing, water softening and, if appropriate, metal, in particular silver protection or a glass protection function, are combined in a preferably solid form.
- Such agents are referred to as multifunctional agents lo.
- drying performance is understood to mean the extent to which the washed ware still has water, preferably water droplets, on the surface after having passed through the dishwashing process. The water remaining on the surface must then either be removed mechanically (eg by drying) wipe) or allow the items to be air dried, so the user must wait for the water to evaporate, leaving residues on the surface (eg limescale and / or residues of surfactants or others)
- EP 1 306 423 A2 discloses aqueous
- additives for cleaning agents must not adversely affect the rinsing and, in particular, the rinsing performance of the cleaners. Ideally, an additive should even improve the overall performance of the cleaner. It has now been found that the combination of certain surface-active substances is suitable for improving the drying performance of hard-surface cleaners, in particular dishwashing compositions, and more particularly in multifunctional compositions, while being ecologically harmless.
