Description

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

liquid Aqueous hand dishwashing detergents are available in countless numbers Households used. A problem with using such hand dishwashing detergents It is because of the longer lasting Leakage of the skin in an aqueous medium already through the moisture can cause irritation to the skin, in particular if the skin is often in the aqueous medium immersed and / or for a long time the aqueous Medium is exposed. The irritation of the skin may be due to this the ingredients contained in the hand dishwashing detergent be further strengthened.

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

Surprisingly has now been found that by adding certain microorganisms in the dishwashing detergent, in particular selected from the families of Lactobacteriaceae and Bacillaceae, the negative Reduced consequences of hand dishwashing for the skin could be and beyond that a significant positive Effect, in particular a nourishing effect, exerted on the skin could be, so that overall the skin compatibility Hand dishwashing detergent could be improved without in any way at the same time the cleaning performance of the hand dishwashing detergent to impair.

The use of such microorganisms in cosmetic skin treatment compositions is already known. So will be in about US 6790434 describe the use of such microorganisms in cosmetic skin treatment agents in conjunction with a plant extract from the extracellular matrix, thereby counteracting the skin damage caused by UV radiation. However, the use of these microorganisms in detergents and cleaners is not disclosed.

Also within certain limits an influence on the viscosity of the mixture by this Medium possible. Furthermore, this component influences the solubility of the mixture. This component becomes special preferably used at high surfactant contents, in particular at Tensidgehalten above 30 wt .-%.

can however, their use is omitted, so is the invention Agent preferably free from dicarboxylic acid (salts) n.

PH value

Of the pH of the agent of the invention can by means of conventional pH regulators, for example acids such as mineral acids or citric acid and / or alkalis such as sodium or potassium hydroxide, be set, wherein - especially when desired Hand tolerance - a range from 4 to 9, preferably 5 to 8, in particular 5.5 to 7.5, is preferred.

For adjusting and / or stabilizing the pH, the agent according to the invention may contain one or more buffer substances (INCI Buffering Agents), usually in amounts of 0.001 to 5 wt .-%, preferably 0.005 to 3 wt .-%, in particular 0 , 01 to 2 wt .-%, particularly preferably 0.05 to 1 wt .-%, most preferably 0.1 to 0.5 wt .-%, for example, 0.2 wt .-%. Preference is given to buffer substances which are at the same time complexing agents or even chelating agents (INCI chelating agents). Particularly preferred buffer substances are the citric acid or the citrates, in particular the sodium and potassium citrates, for example trisodium citrate.2H ₂ O and tripotassium citrate H ₂ O.

use

The inventive agent can be for Cleaning hard surfaces, especially for manual Use cleaning of dishes. Here it is characterized by the contained surfactant combination by a good drainage and drying behavior It also shows thanks to the abrasive action of the salts it contains a very good cleaning performance even on stubborn and burned stains, and finally owns It also a high skin friendliness.
