Description

The invention relates to the use of aqueous liquid surfactant-containing cleaning agents for hard surfaces, especially glass, with naphthalenesulfonic acid-formaldehyde condensate.

The cleaning agents for hard surfaces that are common today are usually aqueous preparations in the form of a stable solution or dispersion which contain, as essential active ingredients, surface-active substances, organic solvents and, if appropriate, complexing agents for the hardness constituents of the water, abrasive substances and cleaning alkalis. Detergents, which are primarily intended for cleaning glass and ceramic surfaces, are often formulated as solutions of the active substances in a mixture of water and water-miscible organic solvents, primarily lower alcohols and glycol ethers. Examples of such agents can be found in the German Offenlegungsschrift22 20540, US patents 3,839,234 and 3,882,038 and in European patent applications 344 847 and 393 772nd

US-A-5372741, EP-A-364260 and WO-A-9412606 describe detergents containing Surfactants and naphthalene sulfonic acid formaldehyde condensates.

When using detergents, there is also a requirement for high Cleaning performance also the requirement for simple and convenient use of means. Most of the time, it is expected that the funds will be available without a single order further measures deliver the desired effect. This is particularly the case here on smooth surfaces, especially those such as glass or ceramics can reflect specularly, difficulties in that agents that clean well, usually do not dry streak-free, while such agents that are essentially without Dry visible residues, have only a limited cleaning effect. In order to achieve a sufficient cleaning effect with an acceptable residue behavior, in particular to achieve greasy soiling, it is necessary to use the cleaning agents in addition to organic solvents also larger amounts of more or add less volatile alkalis. Here in particular have ammonia and alkanolamines Application found. Cause higher concentrations of ammonia or amine however, in addition to a noticeable odor nuisance, a corresponding increase of the pH in the detergent solution with the result that more sensitive Surfaces such as paint surfaces are significantly attacked by these cleaning agents become.

With smooth surfaces, especially those that can reflect like glass or ceramics, there are also two special problems that usually do not come to light immediately after the cleaning process, but usually only at a later point in time. On the one hand, this is the well-known but disturbing phenomenon of the condensation of water on the aforementioned surfaces, for example in the bathroom during and after showering or bathing, which is referred to below as a fogging effect. On the other hand, it is the well-known as well as unpleasant - albeit long-term unavoidable - event that after cleaning a reflective surface exposed to the weather, such as window glass, a rain shower with the subsequent rain spots stains the cleaning result, which is referred to below as the rain effect.

There was therefore still a need for cleaning agents with high cleaning performance do not have the disadvantages mentioned.

From WO 96/04358 A1 ( Procter & Gamble ) cleaning agents are known which can clean glass without leaving stains and / or films to an annoying extent and which contain an effective amount of a substantive polymer with hydrophilic groups which the glass coexists with a long-lasting higher hydrophilicity, so that at least with the next three re-wetting, for example by rain, the water runs off flatly and less stains remain after drying. Substantive polymers are in particular polycarboxylates such as poly (vinylpyrrolidone-coacrylic acid), but also poly (styrene sulfonate), cationic sugar and starch derivatives and block copolymers composed of ethylene oxide and propylene oxide, the latter polyethers in particular having less substantivity.

Surprisingly, it has now been found that these tasks are achieved by using naphthalenesulfonic acid-formaldehyde condensate be solved.

The invention relates to the use of detergents containing surfactants for hard surfaces containing one or more naphthalenesulfonic acid-formaldehyde condensates included to reduce rain and / or fogging.

A particular advantage of the present invention is that naphthalenesulfonic acid-formaldehyde condensate an anti-rain and anti-fog effect at the same time is effected. In addition, these condensates can be clear and stable in storage without any problems work into the cleaning agents.
