Independent claims are also included for: (a) the use of (I) in the liquid cleaner for shortening the drying time of the treated surface; (b) a method of shortening the drying time of the treated surface by treatment with the cleaner in concentrated or diluted form.

Description

The invention relates to aqueous liquid surfactant-containing cleaning agents for hard surfaces with diquaternary polysiloxane.

Universally usable cleaning agents for all hard, wet or damp wipers Household and commercial surfaces are known as so-called all-purpose cleaners represent predominantly neutral to weakly alkaline aqueous liquid products, the 1 to 30% by weight surfactants, 0 to 5% by weight builders (e.g. citrates, gluconates, soda, polycarboxy late) 0 to 10% by weight of hydrotropes (e.g. alcohols, urea), 0 to 10% by weight of water-soluble che solvents (e.g. alcohols, glycol ethers) and optionally u. a. Skin protection products, Dyes and fragrances included. It is usually used as an approx. 1% solution in Water, also undiluted for local stain removal. In addition, are ready to use All-purpose cleaner as so-called spray cleaner in the trade.

All-purpose cleaners are very often used to clean hard floor coverings such as stone, Ceramic or plastic, in private households, especially in the kitchen and bathroom area, used. The cleaning is expediently carried out preferably in the input direction, ie. H. the user is working a distant end of the room towards the entrance because the fresh wiped floor usually wet up to about 15 minutes and not without staining is walkable. This poses a problem, particularly in the area of commercial building cleaning because the freshly cleaned floor surfaces by the during the cleaning process usually continuous public traffic who is immediately soiled again the, whereby this renewed soiling is possible the longer, the slower the Reini ger or its aqueous solution dries on the floor surface.

WO 96/26260 A1 (Unilever N.V.) describes aqueous cleaning agents for hard surfaces Chen known that a surfactant mixture with, based on the total amount of surfactant, (a)  at least 65% by weight nonionic surfactant, (b) less than 1% by weight anionic ten sid and (c) 0.1 to 35 wt .-% diquaternary poly (dimethylsiloxane) and the Ober Make surfaces hydrophobic and provide them with a protective film. The means are preferred free of anionic surfactant as it reduces the effectiveness of the agents.

From DE 37 19 086 C1 (Th. Goldschmidt AG) and EP 0 294 642 B1 (Th. Goldschmidt AG) are diquaternary polysiloxanes, especially diquaternary poly (dimethylsiloxanes), and their production and their use in cosmetic preparations, in particular for hair care, known.

The object of the present invention was to provide means for cleaning hard surfaces or To provide cleaning procedures that are different from conventional agents or process faster drying of the hard surface moist after the treatment Chen or identify an active ingredient that can be used for this purpose.
