• the invention relates to multi-phase liquid cleaning agents with an antimicrobial effect, which can be temporarily emulsified by shaking and can be used for cleaning hard surfaces, in particular glass, a product containing the agent and a method for cleaning and / or disinfecting or sanitizing hard surfaces.
• 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.

• Spray dispensers are described in greater detail in WO 96/04940 (Procter & Gamble) and the US patents cited therein for spray dispensers, all of which are referred to in this regard and the contents of which are hereby incorporated into this application.
• the agents according to the invention are preferably used in such a way that the agent temporarily converted into an emulsion by shaking in amounts of about 1.5 to 10 g per m 2 , in particular 3 to 7 g per m 2 , of the agent to be cleaned and / or apply disinfectant or sanitizing surface and immediately wipe these surfaces with an absorbent soft object, thereby cleaning and / or disinfecting or sanitizing.
• the agents are preferably applied with the aid of suitable spray devices, in particular a spray dispenser or a product according to the invention, in order to achieve a distribution which is as uniform as possible. Sponges or cloths, which can be rinsed out with water from time to time when treating larger areas, are particularly suitable for wiping.
• the agents according to the invention can be produced by separately mixing the individual phases directly from their respective raw materials, then combining and mixing the phases and finally standing the agent to separate the temporary emulsion. They can also be prepared by mixing them directly from their raw materials, then mixing them and then standing the agent for separating the temporary emulsion. Insofar as a component is not completely insoluble in a phase other than the phase to which the respective component is attributed or with which it was introduced into the composition, this other can also Phase contained in the setting of solubility equilibria by diffusion corresponding proportions of the component concerned.
• Table 1 shows the composition of the exemplary agents E1 and E2 according to the invention. Served as the aliphatic gasoline hydrocarbon The compositions contained below a transparent aqueous phase I and above a creamy emulsion of phase I in non-aqueous phase II, the volume of emulsified phase I each making up about a third of the volume of phase II, in a volume ratio of phase I to the emulsion of Phase I in phase II from about 80 to 20 and separated by a sharp interface. The temporary emulsion generated by shaking remained stable for a period of about 3 minutes sufficient for the convenient application of the agent, whereupon the phases were separated again.
