Description

, Cleaning supplies' '

The present invention relates to a liquid bleach-containing hard surface cleaner.

Oxygen based bleach-containing liquid cleaners are stable only in the acidic or neutral pH range. In the alkaline range, they quickly split off oxygen. Purification -effective lipolysis (i.e., the conversion of the fat to a water-soluble state) is possible only in the alkaline range. Thus, there is an incompatibility between the requirement for stability of a liquid bleach-containing agent on the one hand and the demand for high cleaning performance against fats and oils on the other hand. Although nonaqueous solvents are often effective in removing fat in the acidic range, their efficiency usually either does not match the performance of conventional surfactants or is ecologically inappropriate.

It is therefore desirable to have a new cleaning mechanism for bleach-containing cleaners which is not based on lipid splitting with alkalis or the solubility of fats in solvents and nevertheless ensures a very good separation of fats and oils.

The invention, which fulfills this desire, is a water-containing bleach-containing cleaning agent having a pH in the range of 0.5 to 7, containing (I) an active ingredient selected from the group comprising alkylbenzenesulfonic acid, fatty acid, alkyl ether sulfonic acid and mixtures at least two of these, (II) an oligoester obtainable by reacting (A) 20 to 50 mol% of at least one dicarboxylic acid compound, (B) 10.1 to 29.9 mol% of at least one polyol compound having at least 3 OH groups, (C) 10.1 to 50 mol% of at least one water-soluble alkylene oxide addition product of at least one C ₂ to C ₄ alkylene oxide to a C ₆ to C ₆ alcohol in a molar ratio of 4 to 100 moles of alkylene oxide to 1 mole of alcohol and (D) 0 to 30 mol% of at least one diol compound, and (III) hydrogen peroxide. The agent according to the invention comprises at least one of the anionic surfactants mentioned under (I). Alkyl ether sulfates (fatty alcohol ether sulfates, INCI alkyl ether sulfates) are products of sulfation reactions on alkoxylated alcohols. In this context, the person skilled in the art generally understands, under alkoxylated alcohols, the reaction products of alkylene oxide, preferably ethylene oxide, with alcohols, in the context of the present invention preferably with longer-chain alcohols, ie with aliphatic straight-chain or one or more branched, acyclic or cyclic, saturated or mono- or polyunsaturated, preferably straight-chain, acyclic, saturated, alcohols having 6 to 22, preferably 8 to 18, in particular 10 to 16 and particularly preferably 12 to 14 carbon atoms.

But they can also serve for cleaning hard surfaces, especially in shiny surfaces, where also a good cleaning performance is highly desirable. Hard surfaces in the context of this application are therefore next windows and mirrors and other glass surfaces and, for example, surfaces of ceramic, plastic, metal or (especially painted) wood, which are found in household and commercial, such as bathroom ceramics, kitchen surfaces or floors.

Another subject of the invention is therefore the use of an aqueous cleaning agent according to the invention for cleaning hard surfaces, in particular glass. Examples
