Independent claims are also included for: (a) a product with the cleaning agent in a container with a spray with outlet(s) for spraying the agent, preferably with a jet at the end suitable for foaming the product; (b) a process for cleaning hard surfaces, especially forming a hollow, by spraying with the agent, especially the product, so that the surfaces and/or hollow are (partly) covered with foam and removing residual foam or cleaning agent, especially by rinsing with water and/or wiping with an absorbent article; and (c) cleaning foam obtained by spraying the agent, preferably using the product.

Description

The invention relates to a cleaning agent, a product containing the cleaning agent, a cleaning foam obtained by spraying the cleaning agent, the use the cleaning agent or the product for cleaning hard surfaces and an ent speaking cleaning method.

Household cleaning products such as bathroom and toilet cleaners and All-purpose cleaner, hand dishwashing liquid, machine dishwashing liquid and detergent, who which are offered in different states, with which special consumer-relevant Benefits. For example, tablets make dosing and handling easier of a product. Gel-shaped products (gels) can be applied specifically to soiling be because they are longer on the one to be cleaned - especially inclined or even lower right - adhering to the surface, thin-bodied products, on the other hand, become large areas used and are characterized by simple handling, for example Much easier to mix with water for dilution purposes than viscous products or gels.

Another, because of its simplicity in handling and dosage in household, commercial and industry established offer form is the spray. Are sprayed z. B. hair and body care products, deodorants, perfumes, odor improvers, disinfectants and pests warfare agents, floor, glass and furniture care products, varnishes and paints as well as Au pot care products. In addition to the easy handling and convenient dosing, stand out Sprays in particular through even application and constant effectiveness of the ge content from the outside atmosphere.  

Sprays are understood not only as the spray mist (the spray, the aerosol), but also around The container (spray can) and / or the contents (the spray) are also commonly used. In the technical jargon of the relevant industries, the scientific term aerosol is often used as Used synonymously for spray and spray can. In the following a spray with a Spray device provided container filled with a liquid or flowable agent understood, which is under the pressure of a propellant (compressed gas, aerosol packs). The Spray device is usually designed with a valve and a nozzle as an outlet opening equips; it can be designed in very different ways and thus the removal of the In stop u. a. enable as a mist, foam or liquid jet. It's closed in the container spraying agents - if necessary by shaking beforehand - mixed with liquid propellant. Above this mixture is gaseous propellant, which has a uniform pressure exerts on all sides, including the liquid level of the propellant. If you press the valve, which is usually designed as a button on the outside, the valve opens. The propellant-containing agent is pushed through the valve by the gaseous propellant escapes from the nozzle. The blowing agent added to the agent evaporates immediately. Depending on The design of the valve dustes the active ingredient solution, for example to the finest fog or forms fine-bubble foam. In this context, the statements in RÖMPP Lexicon Chemie (10th edition, 1996-1999, 6 volumes, ISBN 3-13-107830-8, Georg Thieme Verlag, Stuttgart / New York) under the keyword "sprays" and the diagram shown there a spray can and the literature cited.

A particular problem when cleaning hard surfaces means poorly accessible ones hard surfaces, in particular hard surfaces forming cavities. Especially celebrity nente surfaces of this type represent the U-shaped areas inside under the edge of the wefts rinsing toilets. Analog cavities are also often found in urinals. Vastness Re difficult to access and accordingly difficult to clean surfaces are cavities in Form of drains and overflows from sinks, sinks and bathtubs.

The usual liquid or thickened or gel detergents are capable of said Inadequate cleaning of surfaces. They are usually applied as a jet of liquid applied to the surface to be cleaned and flow away by gravity, the Flow rate depends on their rheology, especially the viscosity. Areas on  which the liquid jet is not directed directly or - because of lack of accessibility - who that can be so often not even wetted by the cleaning agent.

It was therefore an object of the present invention to address the cleaning problems described hard to access hard surfaces.

This works if you use a foam for cleaning that has its final maximum Volume not immediately - suddenly - after its creation by spraying a Rei detergent, but builds up with a time delay and thus into cavities and other hard-to-access hard surfaces grows in and eventually completely fills in and thus completely wets the surfaces.

Such a foam can be obtained by spraying a cleaning agent, among other things rem contains thickener.

A first object of the invention is accordingly a cleaning agent that

• A) one or more thickeners,
• B) one or more foam-forming surfactants,
• C) one or more blowing agents and
• D) a liquid aqueous carrier

contains.

Table 1

The agents or products were used to clean flush toilets in the poorly accessible Chen cavity area under the U-shaped - or rather ∩-shaped - inner edge of the Toilet bowl used. The spray cans were sprayed before the foam was applied shakes. During the spraying of the foam, the products with the valve button held down.  

The agents or products according to the invention delivered a particularly fine-bubble Foam, the volume of which increased significantly after spraying and thus the ge filled the entire cavity area. The foam was stable for a long time and adhered well to the Surface so that longer contact times were possible. Then the foam settled rinsed off easily and left a shiny surface.

In contrast, there was no delay in the comparison agent V1 foam Observe volume build-up when spraying. The foam closed accordingly when spraying immediately the U-shaped cavity area, so that the foam the cavity only partially filled the space. The foam was less dimensionally stable and stuck worse on the surface. After rinsing, the cavity area was only partially ge cleans.
