Abstract

An abrasive-containing liquid cleaning agent which is largely transparent and has a surfactant content of more than 15% by weight can be used as a hand dishwashing detergent and in particular for pre-cleaning heavily soiled dishes and as a cleaning agent for hard surfaces.

Description

The invention relates to liquid abrasives Detergent for hard surfaces, which are largely transparent and contain more than 15% by weight of surfactant.

Conventional abrasives liquid Detergent for hard surfaces are usually milky, cloudy, viscous solutions. They are also well known to consumers as "scouring milk" Name that also has the whitish-cloudy look reflects this means.

Liquid dishwashing liquid usually have a transparent look. The clear means in connection with the most commonly used bright colors obviously have a special one positive effect on the consumer, because this makes it a special one high cleaning performance is connected. Furthermore, it is desirable that in particular Hand dishwashing detergents form a sufficient foam, because the consumer also with this combines good cleaning performance. Finally, to ensure a good cleaning performance also requires a certain surfactant content.

The international application WO 02/38720 describes clear surfactant-containing cleaning gels with macroscopic Abrasivstoftteilchen. As such, inorganic substances can as well are used like polymer granules or hard waxes. there the surfactant content is between 0.1 and 15%. The gels are used for cleaning hard surfaces used. Agents with surfactant contents above 15 wt .-% are not revealed.

In the patent EP 292 910 describes a stable liquid aqueous abrasive cleaning agent for hard surfaces. The abrasive particles should not scratch the surface to be cleaned. Various plastics are proposed as abrasives, and the particles can have a size of 10 to 150 μm. The cleaners described, which are referred to several times as "creamy", are obviously abrasive milk, but transparent agents are not presented. In addition, the agents are alkaline with a pH between 10 and 12.

WO 00/36078 relates to transparent or translucent liquid detergents for textiles, in which active ingredients are encapsulated with the aid of polymeric thickeners be suspended. These are enzymes, bleach, perfumes etc., in the liquid Means should be incorporated stable. Abrasives are against it not intended as ingredients.

The German registration DE-A 19918267 finally describes hand dishwashing liquid in which microcapsules with various active ingredients are suspended. An abrasive effect of these suspended particles is also not intended here, but the shell of the microcapsules opens up during use and releases the active ingredient contained therein.

Hand dishwashing liquid and other cleaning agents for hard Surfaces, which show good cleaning performance and strong for removal adhering soiling contain an abrasive, without the Application to scratch the surface to be cleaned, but doing so at the same time one for So far, the consumer does not have an attractive appearance described.

Object of the present invention it is therefore to provide a cleaning agent for hard surfaces, which contains an abrasive, has a good cleaning performance and is also visually appealing is.

use

The cleaning agent according to the invention can be as hand wash detergent in more usual Use way. In addition, it can also be used in a concentrated form Pre-cleaning of dishes, especially heavily soiled ones, if necessary Use dishes with burnt-on grease soiling. After all, it is Means also suitable for manual cleaning of hard surfaces, for example made of glass, ceramic, plastic, enamel or metal, in the home and commercial.

manufacturing

Leave the cleaning agents according to the invention on all the usual, produce ways known to those skilled in the art.

Preferably either, if necessary Thickeners pre-swollen in cold or warm water and subsequently the remaining Components stirred in, or water, surfactants and any other components that may be present are put together and stirred one after the other, if these are used, perfume and / or dye and finally the possibly pre-swollen thickener into stirred. Subsequently the pH value is set as described above and finally the Abrasive particles mixed in.

Examples

The hand dishwashing detergent according to the invention E1 to E4 were each containing abrasive particles formulated by 1 wt .-%. The two comparative examples V1 and V2 had consistently the same composition, but they were without abrasive manufactured. The one after that conducted The cleaning performance test showed clear advantages of the agents according to the invention on.

Table 1: Exemplary compositions

Cleaning performance test:

The cleaning performance was determined by a modified Gardner test apparatus. This was done Tomato cheese sauce or gravy as test soiling on a stainless steel plate with a squeegee in one Layer thickness of 450 μm passed and baked at 120 ° C. for 1 h. Then was the number of strokes determines an automatic wiper, which is equipped with a 4 ml of each agent soaked Cloth equipped was needed around the test stain completely to remove. A stroke is a double movement of the with the Carriage fitted with the detergent over the plate to be cleaned (back and forth). The soiling was considered to be completely removed, if five people agree after an evaluation the dirt with the bare Eye was no longer recognizable. The specified number of strokes also represents represents the mean of three measurements.

The result is as follows Reproduced table:

Table 2: Test for cleaning performance

The results clearly show that when used of a cleaning agent according to the invention With abrasive particles, complete cleaning is essential can be achieved faster than with a conventional, abrasive-free Cleaning supplies.
