Description

Wassermischbare Konzentrate mit einem hohen Gehalt an Tensiden zum Beispiel vom Typ der Handwaschlotionen stellen für Mikroorganismen ideale Nährböden dar, so daß diese Produkte vor dem Befall und der Zersetzung durch Mikroorganismen - insbesondere Bakterien, Pilze und Sporenbildner - geschützt werden müssen. Der unerwünschte Eintrag solcher Mikroorganismen kann beispielsweise bei der Herstellung oder bei der Verwendung des Produktes auftreten. Es ist übliche Praxis, Reinigungsmittel beziehungsweise entsprechende Konzentrate der geschilderten Art durch Konservierungsstoffe zu schützen, wobei eine durch die Kosmetikverordnung begrenzte Anzahl von Konservierungsstoffen zur Verfügung steht.Water-miscible concentrates with a high content of surfactants, for example of the type of hand-washing lotions, 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.

Handwaschlotionen unterliegen nicht dem Arzneimittelgesetz. An sie müssen aber beim Einsatz insbesondere im Medizinalbereich, also im Krankenhaus, in der Arztpraxis oder allgemein bei der Krankenpflege besondere Anforderungen gestellt werden. Bei den hier geschilderten Anwendungsfällen besteht die erhöhte Gefahr einer Kontamination der wassermischbaren Lotionen mit pathogenen Mikroorganismen und Sporenbildnern. Die entsprechenden Reinigungsmittel sollten dementsprechend die Fähigkeit besitzen, eventuell auftretende Verkeimungen selbsttätig zu eliminieren. Das ist mit den gebräuchlichen Konservierungsmitteln, die in den zugelassenen Einsatzkonzentrationen nur mikrobistatische, jedoch keine mikrobizide Wirkung zeigen, nicht möglich.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. This is not possible with the usual preservatives, which only show microbistatic, but no microbicidal, effects in the approved use concentrations.

Zur Entwicklung autosteriler Reinigungsmittel beispielsweise von der Art der Handwaschlotionen für den Medizinalbereich muß dementsprechend nach Möglichkeiten gesucht werden, durch Zusatz geringer Mengen an toxikologisch - insbesondere dermatologisch - unbedenklicher Substanzen neben der bereits durch den Zusatz von Konservierungsstoffen erreichten Haltbarmachung eine mikrobizide Wirkung zu erreichen.For the development of autosterile cleaning agents, for example of the type of hand-washing lotions for the medical sector, it is accordingly necessary to look for ways of achieving a microbicidal effect by adding small amounts of toxicologically - in particular dermatologically - harmless substances in addition to the preservation already achieved by the addition of preservatives.

Es ist bekannt, daß man durch Zugabe geringer Mengen von Wasserstoffperoxid zu wässrigen Desinfektionsmitteln selbstdekontaminierende Hautdesinfektionsmittel gewinnen kann. So schildert die DE-OS 29 04 217 Desinfektionsmittel auf Basis von wässrigen Alkohollösungen, die zusätzlich geringe Mengen von Wasserstoffperoxid enthalten. Desinfektionsmittel dieser Art sind in der Lage, unfreiwillig eingebrachte Sporen abzutöten und damit das Desinfektionsmittel im Gebrauch keimfrei zu halten.It is known that self-decontaminating skin disinfectants can be obtained by adding small amounts of hydrogen peroxide to aqueous disinfectants. DE-OS 29 04 217 describes disinfectants based on aqueous alcohol solutions which additionally contain small amounts of hydrogen peroxide. Disinfectants of this type are able to kill spores that have been involuntarily introduced and thus keep the disinfectant germ-free during use.

Gemäß der heutigen Praxis ist es allerdings üblich, zur Verbesserung der Haptik und der Handhabung von Reinigungsmitteln der beschriebenen Art und insbesondere von Handwaschlotionen diese durch den Einsatz von organischen Verdickungsmitteln auf Viskositäten etwa im Bereich von 500 bis 5000 mPas, insbesondere auf Viskositäten im Bereich von etwa 500 bis 4000 mPas - gemessen z.B. mit einem Rotationsviskosimeter der Fa. Brookfield, Modell LVF, bei 20° C, Spindel 4/20 Upmin - einzustellen. Der Zusatz von Wasserstoffperoxid zu solchen eingedickten tensidhaltigen Reinigungsmitteikonzentraten bringt erhebliche Konfektionierungsprobleme, da schon durch den Zusatz geringer Mengen an Wasserstoffperoxid die viskositätsregulierenden Eigenschaften der herkömmlichen Verdicker verloren gehen.According to current practice, however, it is customary to improve the feel and handling of cleaning agents of the type described and in particular hand wash lotions by using organic thickeners to viscosities in the range from about 500 to 5000 mPas, in particular to viscosities in the range of about 500 to 4000 mPas - measured, for example, using a Brookfield rotary viscometer, model LVF, at 20 ° C., spindle 4/20 rpm. The addition of hydrogen peroxide to such thickened surfactant-containing cleaning agent concentrates poses considerable packaging problems, since the addition of small amounts of hydrogen peroxide loses the viscosity-regulating properties of the conventional thickeners.

In der US-A 4 130 501 werden wäßrige Wasserstoffperoxidlösungen beschrieben, die neben einem vernetzten Polymeren als Verdickungsmittel Fettsäuremono- und -diethanolamide als oberflachenaktive Substanzen enthalten. Die Viskosität dieser Zusammensetzungen ist bei der Lagerung nicht stabil.US Pat. No. 4,130,501 describes aqueous hydrogen peroxide solutions which, in addition to a crosslinked polymer as a thickening agent, contain fatty acid mono- and diethanolamides as surface-active substances. The viscosity of these compositions is not stable during storage.

Die US-A 3 440 319 beschreibt eine wäßrige keimtötende Zusammensetzung, die einen halogenierten keimtötenden Wirkstoff und entweder Wasserstoffperoxid allein oder eine Kombination aus Wasserstoffperoxid und einem wasserlöslichen anorganischen Sulfit als Verfärbungsinhibitor enthält. Anionische, kationische oder nichtionogene Tenside, wie z.B. Fettsäurealkanolamide können vorhanden sein. In dieser Druckschrift wird kein Gehalt an Salzen wie Ammoniumsulfat, Natriumchlorid, Kaliumchlorid, Natriumsulfat oder Kaliumzitrat erwähnt.US-A 3 440 319 describes an aqueous germicidal composition which contains a halogenated germicidal active ingredient and either hydrogen peroxide alone or a combination of hydrogen peroxide and a water-soluble inorganic sulfite as a discoloration inhibitor. Anionic, cationic or non-ionic surfactants, e.g. Fatty acid alkanolamides can be present. In this document, no content of salts such as ammonium sulfate, sodium chloride, potassium chloride, sodium sulfate or potassium citrate is mentioned.

Die US-A 3 833 565 beschreibt im Zusammenhang mit dem Wirkstoff Phenylantimon-bis(2-pyridinthiol-1-oxid) antimikrobiell wirksame Zusammensetzungen, die Fettsäurealkanolamide enthalten.US Pat. No. 3,833,565 describes, in connection with the active ingredient phenylantimony-bis (2-pyridinthiol-1-oxide), antimicrobial compositions which contain fatty acid alkanolamides.

Die Erfindung geht von der Aufgabe aus, tensidhaltige eingedickte Reinigungsmittel und insbesondere Reinigungsmittelkonzantrate zur Verfügung zu stellen, die durch Mitverwendung geringer Mengen an Wasserstoffperoxid die Fähigkeit zur selbsttätigen Sterilisation besitzen, in ihrem physikalischen Erscheinungsbild gleichwohl den gewünschten viskos angedickten Massen entsprechen.The invention is based on the object of providing surfactant-containing thickened cleaning agents and, in particular, cleaning agent 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 compositions.

Die Lösung dieser erfindungsgemäßen Aufgabenstellung geht von der Feststellung aus, daß die gemeinsame Verwendung von Wasserstoffperoxid mit der im folgenden geschilderten Kombination von Fettsäurealkanolamiden und anorganischen Salzen zum gewünschten Eigenschaftsbild führt.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.

Gegenstand der Erfindung sind dementsprechend angedickte wassermischbare und autosterile Reinigungsmittelkonzentrate, insbesondere für den Einsatz als Handwaschlotion im Medizinalbereich, mit einer Viskosität im Bereich von 500 bis 5000 mPas, gemessen mit einem Rotationsviskosimeter der Fa. Brookfield, Modell LVF, Spindel 4/20 Upmin, bei 20°C, enthaltend 5 bis 15 Gewichtsprozent waschaktive Tenside, ausgewählt aus der aus Alkylethersulfaten, Amidethersulfaten, Sulfobernsteinsäureestern und Eiweiß-Fettsäure-Kondensaten bestehenden Gruppe, in Form ihrer Na-, (NH4)- oder Ethanolamin-Salze, dermatologisch verträgliche Desinfektions- und/oder Konservierungsmittel sowie gewünschtenfalls übliche Zusatzstoffe wie Rückfetter, Perlglanzmitel, Duftstoffe und Farbstoffe. Dise Reinigungsmittelkonzentrate sind dadurch gekennzeichnet, daß sie zusammen mit 0,05 bis 2 Gewichtsprozent Wasserstoffperoxid als Eindickungsmittel eine Kombination aus

  • A) 0,2 bis 5 Gewichtsprozent Fettsäurealkanolamiden, und
  • B) 0,5 bis 3 Gewichtsprozent wasserlöslichen, nicht-korrosiven Salzen ausgewählt aus der aus Ammoniumsulfat, Natriumchlorid, Kaliumchlorid, Natriumsulfat und Kaliumcitrat bestehenden Gruppe
    enthalten, wobei die Gewichtsprozentangaben jeweils auf das Gesamtgewicht des Reinigungsmittelkonzentrates bezogen sind.
The invention accordingly relates to thickened water-miscible and autosterile cleaning agent concentrates, in particular for use as hand-washing lotion in the medical field, with a viscosity in the range from 500 to 5000 mPas, measured using a Brookfield rotary viscometer, model LVF, spindle 4/20 rpm, at 20 ° C, containing 5 to 15 percent by weight of detersive surfactants selected from the group consisting of alkyl ether sulfates, amide ether sulfates, sulfosuccinic acid esters and protein fatty acid condensates, in the form of their Na, (NH 4 ) or ethanolamine salts, dermatologically compatible disinfectant and / or preservatives and, if desired, customary additives such as refatting agents, pearlescent agents, fragrances and dyes. Dise cleaning Medium concentrates are characterized in that, together with 0.05 to 2 percent by weight hydrogen peroxide as a thickener, they are a combination of
  • A) 0.2 to 5 percent by weight of fatty acid alkanolamides, and
  • B) 0.5 to 3 percent by weight of water-soluble, non-corrosive salts selected from the group consisting of ammonium sulfate, sodium chloride, potassium chloride, sodium sulfate and potassium citrate
    included, the weight percentages are based in each case on the total weight of the detergent concentrate.

Erfindungsgemäß gelingt mit dieser neuen Möglichkeit der Viskositätsregelung die Einstellung von Viskositäten der Wasserstoffperoxid enthaltenden Waschlotionen auf den in der Praxis besonders gewünschten Bereich bis 5000 mPas und insbesondere von 500 bis 4000 mPas (Brookfield, wie zuvor bestimmt).According to the invention, with this new possibility of viscosity control, the viscosities of the washing lotions containing hydrogen peroxide can be adjusted to the range of up to 5000 mPas, which is particularly desirable in practice, and in particular from 500 to 4000 mPas (Brookfield, as previously determined).

Die Fettsäurealkanolamide leiten sich insbesondere von Fettsäuren des C-Zahlbereichs von etwa 10 bis 22 insbesondere des Bereichs von 12 bis 18 ab. Die Fettsäuren können dabei gesättigt, anteilsweise aber auch olefinisch ungesättigt sein. Besonders geeignet sind z.B. Fettsäurealkanolamidgemische, die sich einerseits von Kokosfettsäuren und andererseits von Ölsäure ableiten.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 12 to 18. The fatty acids can be saturated, but also partially olefinically unsaturated. For example, Fatty acid alkanolamide mixtures, which are derived on the one hand from coconut fatty acids and on the other hand from oleic acid.

Fettsäuredialkanolamide und insbesondere Fettsäurediethanolamide sind die erfindungsgemäß bevorzugten Mischungskomponenten zur Viskositätsregelung. Geeignet sind insbesondere Kombinationen von Kokosfettsäurediethanolamid und Ölsäurediethanolamid in Mischungsverhältnissen im Bereich von 0,2 bis 5:1.Fatty acid dialkanolamides 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.

Die Reinigungsmittelkonzentrate enthalten das Wasserstoffperoxid in Mengen von 0,05 bis maximal 2 Gewichtsprozent - bezogen auf das Gesamtgewicht des Reinigungsmittelkonzentrats - wobei bevorzugt Wasserstoffperoxid in Mengen von 0,1 bis 1,5 Gewichtsprozent und insbesondere in Mengen von 0,2 bis 1 Gewichtsprozent vorliegt. Zusammen mit dem Wasserstoffperoxid können Konservierungsmittel entsprechend des Anhangs VI der EG-Richtlinie Kosmetik zugegen sein. Als Beispiele seien genannt Ester der p-Hydroxybenzoesäure, Brom-5-nitro-1,3-dioxan, 2,4,4'-Trichlor-2-hydroxydiphenylether, Chlorhexidin, Phenolderivate und Aldehyde.The detergent concentrates contain the hydrogen peroxide in amounts of 0.05 to a maximum of 2 percent by weight, based on the total weight of the detergent concentrate, preferably hydrogen peroxide in amounts of 0.1 to 1.5 percent by weight and in particular in amounts of 0.2 to 1 percent by weight. Together with the hydrogen peroxide, 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.

Bei der gemeinsamen Verwendung von Wasserstoffperoxid und Konservierungsmitteln liegt das Mischungsverhältnis solcher von H202 abweichender Konservierungsmittel zum Wasserstoffperoxid vorzugsweise im Mengenbereich von 0 bis 2:1.When hydrogen peroxide and preservatives are used together, the mixing ratio of such preservatives deviating from H 2 0 2 to hydrogen peroxide is preferably in the range from 0 to 2: 1.
