Description

Rinse rinse agent, which Contains polyolalkyl ethers.

This application refers to agents for rinse rinse, especially refers to agents for the rinse rinse intended for machine scrubbing of the dishes containing polyolalkyl ether agents, as well as use of such polyolalkyl ethers.

The commercially available rinsing agents usually represent mixtures consisting of non-ionic surfactants, which form little foam, typically consisting of polyethylene / polypropylene-
glycol ethers of fatty alcohols, solubilizers (for example cumol sulphonate), organic acids (for example citric acid) and solvents (for example ethanol). The task of these agents is to influence the surface tension on the boundary surface of the water in such a way that it can drain from the scrubbed items in the form of a coherent film, as thin as possible, so that in the subsequent drying process there are no remaining drops of water, strips or films. Such agents are known, for example, by publications DE 4323252 and EP 1306422. In this case, however, there is a constant need to improve rinse rinse performance. On the other hand, in recent years, formulations of multifunctional cleaning agents have appeared on the market, which would provide, in addition to a cleaning performance, also at least an additional utility, for example the rinsed by rinsing and / or de-hardening of water for rinsing (products called 2-in-1 or 3-in-1). Combined products consisting of cleaning agents for dishes with rinse rinse agents incorporated are increasingly used both at home and in the industrial sector. In the domestic rinse rinse agents, the rinse rinse agents are dosed separately, as a rule, as a pre-cleaning step and are released into the rinse chamber after the previous rinse process and the cleaning process approximately between 40ºC and 65ºC. In the case of combined agents for dishwashing (for example tablets or powders "2 in 1" or "3 in 1") the rinse aid is formulated by rinsing together with the cleaning agent but is released so that it acts only in the rinse rinse process, which facilitates the handling and dosing of the cleaning agent.

Based on these new formulations they have to develop alternative rinse agents for rinsing, that correspond to the requirements of multifunctional products without a decrease in rinse performance by rinsing. On the other hand there is a need to find Rinse rinse agents more effectively.

The task of the present invention consisted of provide rinse rinse agents with a improved rinse rinse performance, which could formulated simultaneously also to provide products multifunctional

The object of the present invention, in its First embodiment, it consists of agents for the rinsed by rinsing, containing at least a) water, b) a water-insoluble polyolalkyl ether, whose alcohol component contain at least two hydroxyl groups and between three and six atoms of carbon and whose alkyl moiety or whose alkenyl moiety is chosen from residues with 10 to 22 saturated carbon atoms and / or unsaturated, branched or unbranched, and c) a solubilizer and d) optionally an acid, preferably a organic acid, especially a carboxylic acid. For other part is preferred that the agents for rinsing rinse also contain a non-aqueous solvent.
