Description

"Probiotic hand dishwashing detergent"

The invention relates to an aqueous cleaning agent for hard surfaces, in particular a hand dishwashing detergent containing microorganisms, preferably those having a beneficial effect on the skin, as well as its use for cleaning hard surfaces, in particular for the manual cleaning of dishes.

Liquid aqueous hand dishwashing detergents are used in countless households. A problem with the use of such hand dishwashing detergents is that due to the prolonged exposure of the skin in an aqueous medium, moisture may irritate the skin, especially if the skin is often immersed in the aqueous medium and / or for a long time is exposed to the aqueous medium. The irritation of the skin can be further enhanced due to the ingredients contained in the hand dishwashing detergent.

The object of the present invention was therefore to show a way to effectively counteract the negative consequences of manual dishwashing for the skin.

Surprisingly, it has now been found that the addition of certain microorganisms in the dishwashing detergent, in particular selected from the families of Lactobacteriaceae and Bacillaceae, the negative consequences of hand dishwashing for the skin could be reduced and beyond a significant positive effect, especially a nourishing effect on the skin could be exercised so that overall the skin compatibility of the hand dishwashing detergent could be improved without compromising in any way at the same time the cleaning performance of the hand dishwashing detergent.

The use of such microorganisms in cosmetic skin treatment compositions is already known. For example, US Pat. No. 6,790,434 describes the use of such microorganisms in cosmetic skin treatment compositions in conjunction with a plant extract from the extracellular matrix in order to counteract skin damage caused by UV radiation. However, the use of these microorganisms in detergents and cleaners is not disclosed.

Furthermore, the use of certain Bacillus species in sanitary cleaners is known. Thus, WO 97/25865 describes the use of Bacillus species in sanitary detergents which are intended to prevent the multiplication of pathogens and to reduce organic dirt. However, the use of microorganisms with a beneficial effect on the skin is not disclosed here.

The use of microorganisms that exert a positive effect on the skin in hard surface cleaners, especially hand dishwashing detergents, is thus new. An object of the present invention is therefore an aqueous detergent for hard surfaces, in particular a hand dishwashing detergent containing microorganisms, preferably those which exert a beneficial effect on the skin.

The microorganisms are preferably bacteria, more preferably gram-positive bacteria. The bacteria are preferably from the family of Lactobacteriaceae or from the family of Bacillaceae. More preferably, the bacteria are selected from the genera of staphylococci, lactococci, lactobacilli, leuconostocci, streptococci, bacilli, lactobacilli, listeria, actinomycetes, bifidobacteria, caseobacteria, propionibacteria, sporolactobacilli, and coryneform bacteria. Most preferably, the bacteria are lactic acid bacteria.

Another object of the present application is the use of a cleaning agent according to the invention for cleaning hard surfaces, in particular for the manual cleaning of dishes.

Another object of the present invention is also a method for cleaning hard surfaces, in particular for the manual cleaning of dishes, wherein in at least one method step, a cleaning agent according to the invention is used.

Another object of the present invention is also the use of a cleaning agent according to the invention for effecting a beneficial effect on the skin, in particular for the care of the skin and / or for effecting a probiotic effect on the skin. In this context, the effect of a probiotic effect is to be understood as meaning that the growth and / or survivability of undesirable microorganisms present on the skin, in particular pathogenic and / or irritating to the skin, is inhibited, preferably by means of competitive microorganisms Displacement of the unwanted microorganisms by the microorganisms contained in the cleaner and / or possibly due to the acid production by the microorganisms contained in the cleaner. The benefit effect and / or probiotic effect can in particular also be effected by effecting a stimulation of the immune system on the basis of the active substances contained in the microorganisms used, as described, for example, in US Pat. No. 6,790,434.

In a preferred embodiment, the microorganisms settle on the utensil used for cleaning the dishes, for example, cloth, sponge or brush. As a result, it is preferable for the competitive displacement of undesired bacteria, in particular pathogenic or odor-causing microorganisms. Another object of the present invention is therefore also the use of a cleaning agent according to the invention for suppressing the growth of undesirable microorganisms, in particular for suppressing the growth of pathogenic and / or odoriferous microorganisms, in particular on the utensil used for cleaning the dishes, for example on a cloth, a sponge or a brush.

Another object of the present invention is therefore also the use of a cleaning agent according to the invention for suppressing the formation of odor on the utensil used for cleaning the dishes, for example on a cloth, a sponge or a brush.

Another object of the present invention is therefore also the use of a cleaning agent according to the invention for effecting a probiotic effect on the utensil used for cleaning the dishes, in particular on a cloth, a sponge or a brush. In this connection, the effect of a probiotic effect is to be understood as meaning that, owing to the microorganisms contained in the cleaning agent, the growth and / or survivability of undesired, in particular pathogenic and / or odor-forming microorganisms present on the cleaning utensil is inhibited, preferably by competitive displacement unwanted microorganisms by the microorganisms contained in the cleaner and / or optionally due to the acid production by the microorganisms contained in the cleaner.
