Definitions

• Water-miscible concentrates with a high content of surfactants are ideal breeding grounds for microorganisms, so that these products must be protected from attack and decomposition by microorganisms - in particular bacteria, fungi and spore formers. The undesired entry of such microorganisms can occur, for example, during the manufacture or use of the product. It is common practice to protect cleaning agents or corresponding concentrates of the type described by means of preservatives, a limited number of preservatives being available through the Cosmetics Regulation.
• Hand wash lotions are not subject to the Medicines Act. However, they have to meet special requirements when used in particular in the medical field, i.e. in the hospital, in the doctor's office or in general in nursing. In the applications described here, there is an increased risk of contamination of the water-miscible lotions with pathogenic microorganisms and spore formers. Accordingly, the corresponding cleaning agents should have the ability to automatically eliminate any germs that may occur. That is with the common preservatives found in the Permitted use concentrations show only microbistatic, but no microbicidal effect, not possible.
• the invention is based on the object of providing thickened detergent containing surfactants and in particular detergent concentrates which, through the use of small amounts of hydrogen peroxide, have the ability to sterilize themselves, but nevertheless correspond in physical appearance to the desired viscose thickened masses.
• the solution to this problem according to the invention is based on the finding that the joint use of hydrogen peroxide with the combination of fatty acid alkanolamides and inorganic salts described below leads to the desired property profile.
• the invention accordingly relates to thickened water-miscible and auto-sterile cleaning agent concentrates, in particular for use as hand wash lotion in the medical field, which contain detergent surfactants in addition to toxicologically and in particular dermatologically compatible disinfectants and / or preservatives and are characterized in that they are used together with a small amount of hydrogen peroxide contain as a thickener a combination of fatty acid alkanolamides and water-soluble alkali and / or ammonium salts.
• the viscosities of the washing lotions containing hydrogen peroxide can be adjusted to the range of up to approximately 5000 mPas and in particular from approximately 500 to 4000 mPas (Brookfield, as previously determined), which is particularly desirable in practice.
• the fatty acid alkanolamides are derived in particular from fatty acids in the C number range from about 10 to 22, in particular in the range from about 12 to 18.
• the fatty acids can be saturated, but also partially olefinically unsaturated.
• Z are particularly suitable.
• Fatty acid dialkananolamides and especially fatty acid diethanolamides are the mixture components preferred according to the invention for viscosity control.
• Combinations of coconut fatty acid diethanolamide and oleic acid diethanolamide in mixing ratios in the range from 0.2 to 5: 1 are particularly suitable.
• Water-soluble alkali and / or ammonium salts are used together with the fatty acid alkanolamides.
• Non-corrosive, oxidation-resistant simple salts of this type are preferred, with ammonium salts and here in particular ammonium sulfate being particularly important.
• Suitable other water-soluble salts are, for example, sodium and / or potassium salts of inorganic acids such as sodium chloride, potassium chloride, sodium sulfate, but also corresponding salts of organic acids such as potassium citrate.
• the detergent concentrates usually contain the hydrogen peroxide in amounts of about 0.05 to a maximum of about 2 percent by weight, based on the total weight of the detergent concentrate, preferably hydrogen peroxide in amounts of about 0.1 to 1.5 percent by weight and in particular in amounts of about 0.2 up to 1 percent by weight.
• conventional preservatives can be present in accordance with Annex VI of the EC Cosmetics Directive. Examples include esters of p-hydroxybenzoic acid, bromo-5-nitro-1,3-dioxane, 2,4,4'-trichloro-2-hydroxydiphenyl ether, chlorhexidine, phenol derivatives and aldehydes.
• the mixing ratio of such preservatives deviating from H2O2 to hydrogen peroxide is preferably in the range from 0 to 2: 1.
• Suitable surfactant components are all customary, relevant compounds, for example the known alkyl ether sulfates, amide ether sulfates, sulfosuccinic acid esters, protein-fatty acid condensates in the form of their Na or (NH4) or ethanolamine salts.
• the cleaning agent concentrates can contain other usual mixture components, such as refatting agents, e.g. Glycerol EO fatty acid esters, fatty alcohol polyalkylene ether, polyol fatty acid esters, wax esters, pearlescent agents, e.g. Contain fatty acid monoethanolamide, fatty alcohol ether sulfates, fragrances and / or dyes.
• refatting agents e.g. Glycerol EO fatty acid esters, fatty alcohol polyalkylene ether, polyol fatty acid esters, wax esters
• pearlescent agents e.g. Contain fatty acid monoethanolamide, fatty alcohol ether sulfates, fragrances and / or dyes.
• detergent concentrates of the type according to the invention contain the following components in aqueous and / or water-soluble organic solution or slurry in the following quantitative ranges - percent by weight, again based on the total weight of the detergent concentrate: 5 to 15 percent by weight of detergent surfactants 0.5 to 5 percent by weight of the other additives such as refatting agents, pearlescent agents, fragrances and colorants 0.2 to 1 percent by weight of hydrogen peroxide, if desired in a mixture with conventional preservatives and / or disinfectants 0.5 to 3.5 percent by weight of the fatty acid alkanolamides, in particular a combination of coconut fatty acid diethanolamide and oleic acid diethanolamide in the ratio from 0.2 to 5: 1 0.8 to 2.5 percent of the alkali and / or ammonium salts
• the viscosity of the cleaning agent concentrates is preferably set in the range from approximately 500 to 5000, in particular in the range from approximately 500 to 4000 mPas. Assemblies of the type described show the effect of self-decontamination. They are stable in storage tests under changing climate conditions in the temperature range from 0 to 40 ° C.
• a hand wash lotion (Lotion A) with the following composition was produced: 6 wt .-% sodium salt of a C14 fatty alcohol ether sulfate with 4 EO 3% by weight of commercially available triethanolamine salt of a condensation product of protein hydrolyzate and fatty acid (Lamepon (R) ST 40; manufacturer: Chemische Fabrik Grünau, Illertissen) 1 wt .-% C16 fatty acid monoethanolamide 2% by weight adduct of 8 EO on glycerol, esterified with 3 moles of coconut fatty acid 1% by weight propylene glycol 2% by weight ammonium sulfate 1% by weight of coconut fatty acid diethanolamide 1% by weight oleic acid diethanolamide 0.2% by weight of methyl ⁇ -hydroxybenzoate 0.2% by weight of hydrogen peroxide ad 100% by weight of fragrances, dyes, water
