Description

"Cleaning agents for hard surfaces"

The invention relates to aqueous liquid surfactant-containing cleaning agents for hard surfaces, in particular glass, with end-capped polyalkoxylated alcohol and the use of such alcohol in cleaning agents for hard surfaces and a method for treating hard surfaces with cleaning agents containing such alcohol.

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 water, abrasives 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 German Offenlegungsschrift 22 20 540, US Pat. Nos. 3,839,234 and 3,882,038 and in European Patent Applications 344,847 and 393,772.

When using the cleaning agents, in addition to the demand for high cleaning performance, there is also the demand for the simplest and most convenient use of the agents. Most of the time, it is expected that the funds will deliver the desired effect even with a single application without further measures. Difficulties arise especially when used on smooth surfaces, especially those that can reflect like glass or ceramics, because agents that clean well usually do not dry without streaks, while agents that dry essentially without visible residues , have a limited cleaning effect. In order to achieve a sufficient cleaning effect with an acceptable residue behavior, in particular with regard to greasy soiling, it is necessary to also use larger amounts of more or more in addition to organic solvents add less volatile alkalis. Ammonia and alkanolamines in particular have been used here. Higher concentrations of ammonia or amine, however, cause not only a noticeable odor nuisance, but also a corresponding increase in the pH in the cleaning agent solution, with the result that more sensitive surfaces, such as paint surfaces, are significantly attacked by these cleaning agents.

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 an impact 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 remaining rain stains negates the cleaning result, which is hereinafter referred to as the rain effect.

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

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 contain an effective amount of a noun polymer with hydrophilic groups which the glass contains 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-co-acrylic 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.

Epoxy-sealed polyalkoxylated alcohols of the formula A are known from WO 94/22800 A1 (Olin Corp.), R'O [CH ₂ CH (CH) ₃ O] _x [CH ₂ CH ₂ O] _y [CH ₂ CH (R ^ll ) O] _z H (A)

The alcohols of the formula A can be incorporated into powdered and liquid machine dishwashing detergents or cleaning agents for hard surfaces such as bathroom tiles Dishwashing detergents reduce stain and film formation.

Checking anti-fog and anti-rain effects

First, 2 ml of the respective agent were distributed on a mirror measuring 30 cm x 60 cm with a folded fleece of total size 20 cm x 20 cm (Chicopee, Duralace 60) and polished out in a practical manner. A second identical treatment was carried out after 30 minutes. Another 30 minutes later, the anti-fogging and anti-rain effects were tested as follows.

Anti-fog effect. The treated mirror was held for 5 seconds over a dish (28 cm × 50 cm × 4 cm) with 1.5 liters of boiling water and immediately afterwards evaluated whether and how strongly the mirror was fogged up.

Anti-rain effect. Using a pump spray bottle, about 10 g of test rain, prepared from tap water and 8 g / l of wfk carpet pigment dirt (55% by weight of kaolin, 43% by weight of quartz, 1.5% by weight of carbon black 101) were produced within about 4 seconds , 0.5% by weight iron oxide black; wfk code wf -09 W) from w c-Testgewebe GmbH (http://www.wfk.de), sprayed evenly onto the pretreated mirror surface. Immediately afterwards, wetting and droplet formation were evaluated and, after drying, dirt distribution and stain formation.
