Abstract

A prebiotic surfactant combination can be used to maintain desired skin germs or to inhibit the growth of unwanted skin germs in the use of detergents and cleaners and for the preparation of a prebiotic detergent or cleaning agent.

Description

The The invention relates to the use of a prebiotic effective Surfactant combination for the preservation of desired skin germs or to inhibit the growth of unwanted skin germs Users of detergents and cleaning agents as well as for the production a prebiotic washing or cleaning agent.

The human skin surface is of a variety of different Germs colonized. While some of these germs are harmful are and for example acne or various skin diseases can cause (so-called "pathogenic germs"), emanates from others a positive effect (so-called "saprophyte Skin bacteria "). These saprophytes can through her Growth Keep harmful germs in check and practice such a protective function. It is therefore desirable to affect the skin flora so that pathogenic bacteria after Possibility reduced and promoted saprophyte germs become.

The use of prebiotic plant extracts in cosmetic or pharmaceutical preparations for skin treatment is already known. So, for example, deals EP 1658088 A1 with prebiotic active plant extracts used in topical cosmetic or pharmaceutical compositions.

Certain Practice in detergents and cleaners used surfactants or surfactant mixtures a negative influence on the skin flora. It would be therefore beneficial if this harmful influence is minimized could or even surfactants could be used protect the desirable germs or even theirs Promote growth and growth of pathogenic germs inhibit. Of course, this applies in particular to such cleaning applications, where there is direct skin contact with the detergent.

A Object of the present invention was therefore the provision a detergent whose surfactants in as low as possible Measure negatively affect the skin flora or even one exert positive influence.

Surprised It has now been found that a combination of certain surfactants the preservation of the skin flora serves.

One The subject of the present invention is therefore the use of a prebiotic effective surfactant combination to preserve desirable Skin germs when using washing and cleaning agents.

Next the maintenance of the desired saprophyte germs, the surfactant combination Also counteract the colonization of the skin by pathogenic germs.

One Another object of this invention is therefore the use of a prebiotic effective surfactant combination for the inhibition of Growth of unwanted skin germs in the user of washing and detergents

The Surfactant combination is suitable for the production of a washing and cleaning agent with prebiotic effect.

Yet Another object of the invention is therefore the use of a prebiotic effective surfactant combination for the production a prebiotic washing or cleaning agent.

at This washing or cleaning agent may preferably be a hand dishwashing detergent or a laundry detergent.

Of the pH of the agent used according to 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, wherein - in particular with desired hand compatibility - one Range of 4 to 9, preferably 5 to 8, especially 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.

embodiments

Three hard surface cleaners E1 to E3 which can be used according to the invention have been formulated, which have a prebiotic effect due to the surfactant combination they contain. Their compositions are shown in the table below, all amounts are in wt .-% of the active ingredient. E1 E2 E3 Sodium lauryl ether sulfate 6.64 12,00 13,30 cocoamidopropyl 1.67 3.10 3.70 Sodium sec-C _14-17 alkanesulfonate 1.67 2.90 3.00 sodium chloride 1.30 - - ethanol - 1.00 2.00 Perfume 0.20 0.30 0.30 dye 0.20 0.20 0.20 water 88.32 80.50 77,50

Besides A comparative formulation was prepared that contains a surfactant combination from 19% by weight of a secondary alkanesulfonate, 6% by weight of a fatty alcohol ether sulfate and 2% by weight of an amine oxide. One Hand dishwashing detergent containing this surfactant combination showed no prebiotic effects.
