Description

DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD The present invention relates to aqueous surfactant-containing liquid compositions containing end-blocked polyalkoxylated alcohols for cleaning hard surfaces, especially glass, in compositions for cleaning hard surfaces. And a method of treating hard surfaces with a cleaning composition containing this alcohol.

BACKGROUND OF THE INVENTION [0002] Cleaning compositions typically used today for cleaning hard surfaces generally include surfactants, organic solvents, and, optionally, cleaning agents that are important active ingredients. An aqueous preparation in the form of a stable solution or dispersion containing a complexing agent for water hardness components, an abrasive and an alkali. Cleaning compositions, especially for cleaning glass and ceramic surfaces, are often formulated as a solution of the active ingredient in a mixture of water and a water-miscible organic solvent (primarily lower alcohols and glycol ethers). Examples of such compositions are DE-OS 22 20 540, U.S. Patent No. 3,389,234, U.S. Patent No. 3,882,038, European Patent Application No. 344 847 and European Patent Application No.
It can be found in Issue 72.

For practical use, cleaning compositions are expected to have both high cleaning power and simple applicability. In most cases, the composition is required to exhibit the required effect after a single application, ie without further processing. Problems arise here (especially when the composition is applied to smooth surfaces, especially reflective surfaces (eg glass or ceramic surfaces)). Because compositions having advantageous detergency generally cannot be dried without leaving streaks, compositions which can be dried sufficiently without leaving any visible residue have only a limited detergency. Because they don't. In order to have a sufficient cleaning effect (especially for fatty soils) and an acceptable residue behavior, relatively large amounts of somewhat volatile alkalis in addition to the organic solvent must be added to the cleaning composition. Must. In particular, ammonia and alkanolamines are used for this purpose. Unfortunately, relatively high concentrations of ammonia or amines, in addition to emitting an intense odor, increase the corresponding pH value of the cleaning solution,
As a result, relatively sensitive surfaces (eg, paint surfaces) are clearly impaired by the cleaning composition.

[0004] Furthermore, smooth surfaces, especially reflective surfaces (eg glass or ceramic surfaces)
Presents two unique problems that generally do not appear immediately after washing, but only appear at a later stage. The first problem is a well-known but problematic phenomenon that water condenses on the mentioned surfaces (eg, during a shower or bath and thereafter in a bathroom) (hereinafter “membrane effect”). . A second problem is that, after cleaning the reflective surface (eg, window glass) exposed to the weather, the rainwater is poured, which undesirably destroys the cleaning due to the remaining rain marks, and prolongs the cleaning. This is a well-known phenomenon that cannot be avoided (hereinafter referred to as "rainwater effect"). Accordingly, there is still a need for cleaning compositions that have high detergency without all the disadvantages mentioned above.

WO 96/04358 A1 (Procter & Gamble) is capable of cleaning glass without leaving any troublesome dirt and / or film, and imparts a relatively high degree of durable hydrophilicity to glass. Then contains sufficient direct polymer with hydrophilic groups to remove water from the glass surface at least three times when the glass is wet, for example by rain, and to leave little soil after drying. A cleaning composition is described. Direct polymers are in particular polycarboxylates (eg poly (vinylpyrrolidone-co-acrylic acid)), furthermore poly (styrenesulfonates), cationic sugars, starch derivatives and block copolymers of ethylene oxide and propylene oxide (especially the latter Ethers have relatively little directness.)
It is.
