Abstract
Description
Die Erfindung umfasst kosmetische oder dermatologische Zubereitungen mit einem Anteil an Polyglyceryl-10-Stearat, insbesondere mit weniger als 2 Gew.%, bezogen auf die Gesamtmasse der Zubereitung, und Polylysin. Die Zubereitungen zeigen eine verbesserte antimikrobielle Wirksamkeit gegenüber Zubereitungen basierend auf anderen Emulgatorsystemen ohne PG-10-stearat. The invention encompasses cosmetic or dermatological preparations with a content of polyglyceryl-10-stearate, in particular less than 2% by weight, based on the total mass of the preparation, and polylysine. The formulations exhibit improved antimicrobial efficacy over formulations based on other emulsifier systems without PG-10 stearate.
Häufige Erscheinungsformen kosmetischer oder dermatologischer Zubereitungen sind feindisperse Mehrphasensysteme, in welchen eine oder mehrere Fett- bzw. Ölphasen neben einer bzw. mehreren Wasserphasen vorliegen. Von diesen Systemen sind am weitesten verbreitet wiederum die eigentlichen Emulsionen. Aber auch emulgatorarme bzw. -freie Zubereitungen auf Basis sogenannter Hydrodispersionen sind bekannt. Hydrodispersionen stellen Dispersionen einer flüssigen, halbfesten oder festen inneren (diskontinuierlichen) Lipidphase in einer äußeren wäßrigen (kontinuierlichen) Phase dar. Hydrodispersionen sind – wie auch Emulsionen, die sich durch eine ähnliche Phasenanordnung auszeichnen – metastabile Systeme und daher geneigt, in einen Zustand zweier in sich zusammenhängender diskreter Phasen überzugehen. In einer klassischen O/W-Emulsion verhindert die Wahl eines geeigneten Emulgators die Phasentrennung. Im Gegensatz zur klassischen Emulsionen enthalten Hydrodispersionen aber nur sehr geringe Mengen an Emulgatoren bzw. können sogar gänzlich frei von Emulgatoren sein. Common manifestations of cosmetic or dermatological preparations are finely dispersed multiphase systems in which one or more fat or oil phases are present adjacent to one or more water phases. Of these systems, the most common are again the actual emulsions. But emulsifier-poor or -free preparations based on so-called hydrodispersions are known. Hydrodispersions are dispersions of a liquid, semi-solid or solid internal (discontinuous) lipid phase in an external aqueous (continuous) phase. Hydrodispersions are - as well as emulsions characterized by a similar phase arrangement - metastable systems and therefore inclined to a state of two in to pass on coherent discrete phases. In a classic O / W emulsion, the choice of a suitable emulsifier prevents phase separation. In contrast to classical emulsions, however, hydrodispersions contain only very small amounts of emulsifiers or can even be completely free of emulsifiers.
Als kosmetische oder medizinische Zubereitungen sind oftmals Emulsionen, insbesondere W/O-, O/W-, O/W/O oder W/O/W-Emulsionen, im Einsatz. Unter Emulsionen versteht man im Allgemeinen heterogene Systeme, die aus zwei nicht oder nur begrenzt miteinander mischbaren Flüssigkeiten bestehen, die üblicherweise als Phasen bezeichnet werden. In einer Emulsion ist eine der beiden Flüssigkeiten (W/O) in Form feinster Tröpfchen in der anderen Flüssigkeit dispergiert. Die Flüssigkeiten (rein oder als Lösungen) liegen in einer Emulsion in einer mehr oder weniger feinen Verteilung vor, die im Allgemeinen nur begrenzt stabil ist. Emulsions, in particular W / O, O / W, O / W / O or W / O / W emulsions, are often used as cosmetic or medical preparations. Emulsions are generally understood to mean heterogeneous systems which consist of two liquids which are immiscible or only slightly miscible with one another, which are usually referred to as phases. In an emulsion, one of the two liquids (W / O) is dispersed in the form of very fine droplets in the other liquid. The liquids (pure or as solutions) are present in an emulsion in a more or less fine distribution, which is generally limited stability.
Sind die beiden Flüssigkeiten Wasser und Öl und liegen Öltröpfchen fein verteilt in Wasser vor, so handelt es sich um eine Öl-in-Wasser-Emulsion (O/W-Emulsion, z. B. Milch). Der Grundcharakter, zum Beispiel elektrische Leitfähigkeit, Sensorik, Anfärbbarkeit der kontinuierlichen Phase, einer O/W-Emulsion ist durch das Wasser geprägt. Bei einer Wasser-in-Öl-Emulsion (W/O-Emulsion, z. B. Butter) handelt es sich um das umgekehrte Prinzip, wobei der Grundcharakter hier durch das Öl bestimmt wird. If the two liquids are water and oil and oil droplets are finely distributed in water, then it is an oil-in-water emulsion (O / W emulsion, eg milk). The basic character, for example electrical conductivity, sensor technology, dyeability of the continuous phase, an O / W emulsion is characterized by the water. A water-in-oil emulsion (W / O emulsion, eg butter) is the reverse principle, with the basic character being determined by the oil.
Der Stand der Technik kennt mehrere wesentliche Faktoren, die einen positiven Einfluss auf die Stabilität und Rheologie von Emulsionen haben. The prior art knows several important factors that have a positive influence on the stability and rheology of emulsions.
Emulsionen benötigen zu ihrer Bildung und zur Stabilisierung im Allgemeinen einen oder mehrere Emulgatoren, Verdicker und/oder Konsistenzgeber, um über einen kosmetisch akzeptablen Zeitraum stabil zu sein, im Allgemeinen 1 Jahr nach dem Öffnen einer kosmetischen Zubereitung. Dazu werden oft große Mengen an Emulgatoren benötigt. Dies wiederum kann bei Konsumenten zu Missempfindungen bis zur Unverträglichkeit und im Extremfall sogar zu Phänomene wie die Mallorca Akne o.ä. führen. Emulsions for their formation and stabilization generally require one or more emulsifiers, thickeners and / or bodying agents to be stable over a cosmetically acceptable period of time, generally 1 year after opening a cosmetic preparation. This often requires large amounts of emulsifiers. This, in turn, can lead consumers to misperceptions up to incompatibility and, in extreme cases, even to phenomena such as Mallorca acne or similar. to lead.
Wünschenswert ist es daher Emulsionszubereitungen zur Verfügung zu stellen, die möglichst geringe Mengen an Emulgatoren umfassen und dennoch ausreichend stabil formuliert sind. It is therefore desirable to provide emulsion formulations which comprise the smallest possible amounts of emulsifiers and are nevertheless sufficiently stable in formulated.
Damit kosmetische oder dermatologische Cremes und Lotionen nach dem Öffnen noch einige Monate haltbar sind, müssen sie konserviert werden. Entscheidend ist die Wahl der Mittel – denn Bakterien, Pilze und Hefen unterscheiden nicht, ob eine Creme oder Lotion natürliche oder synthetische Stoffe enthält. Einmal öffnen genügt, und schon ist die kosmetischen Zubereitung mit Bakterien, Pilzen und/oder Hefen kontaminiert und können sich vermehren. Die Verkeimung von Kosmetika gilt es aus zwei Gründen zu vermeiden. Zum Einen muss die Formel vor eventuellen Abbau von Rohstoffen geschützt werden. Der Abbau von Rohstoffen kann zu den verschiedensten Veränderungen der Formel führen zum Beispiel Instabilität (wenn z.B. der Emulgator abgebaut wird). Aber auch vor den eventuellen Abbauprodukten der Mikroorganismen muss die Formel geschützt werden (Duft- oder Farbveränderung etc.). Zu guter Letzt können Mikroorganismen Toxine bilden. For cosmetic or dermatological creams and lotions to remain stable for a few months after opening, they must be preserved. Decisive is the choice of means - because bacteria, fungi and yeasts do not distinguish whether a cream or lotion contains natural or synthetic substances. Once opened enough, and already the cosmetic preparation with bacteria, fungi and / or yeasts is contaminated and can multiply. Microbial contamination of cosmetics is to be avoided for two reasons. On the one hand, the formula has to be protected against any potential depletion of raw materials. The degradation of raw materials can lead to a variety of changes in the formula, for example instability (when, for example, the emulsifier is degraded). But even before the possible degradation products of microorganisms, the formula must be protected (fragrance or color change, etc.). Finally, microorganisms can produce toxins.
Gemäß der Council Directive 76/768 EEC dürfen ausschließlich sichere kosmetische Mittel vermarktet werden. Das heißt auch, dass kosmetische Mittel, die aufgrund ihrer chemischen Zusammensetzung und physikalischen Eigenschaften das Wachstum von Mikroorganismen zulassen, konserviert werden müssen. Hierzu sind die in Annex VI der Council Directive 76/768 aufgeführten und als sicher bewerteten Konservierungsmittel einzusetzen, um den Anwender vor durch Mikroorganismen ausgelöste Gesundheitsgefährdungen zu schützen und durch das Wachstum von Mikroorganismen verursachte Produktschädigungen (Abbau oder Veränderungen von Inhaltsstoffen, mikrobielle Stoffwechselendprodukte) abzuwenden. According to Council Directive 76/768 EEC only safe cosmetic products may be marketed. This also means that cosmetic products that allow the growth of microorganisms due to their chemical composition and physical properties must be preserved. To this end, the preservatives listed in Annex VI of Council Directive 76/768 and evaluated as safe must be used to protect the user against health hazards caused by microorganisms Protect and prevent the product damage caused by the growth of microorganisms (degradation or modification of ingredients, microbial metabolic end products).
Damit wird die mikrobiologische Stabilität des kosmetischen Mittels während des Produktlebenszyklus (Produktion, Lagerung, Anwendung) gewährleistet. Die Konzentration von Konservierungsmitteln sollte so gewählt werden, dass diese Ziele erreicht werden, eine Überkonservierung aber vermieden wird. Hierdurch wird für den Anwender das nicht vollständig zu vermeidende Restrisiko von unerwünschten Nebenwirkungen (Hautirritation, Sensibilisierung) zusätzlich minimiert. Die Reduktion an Konservierungsmitteln gelingt jedoch nur, wenn Inhaltsstoffe kosmetischer Mittel zusätzlich als Sekundäreigenschaft antimikrobielle Eigenschaften aufweisen. This ensures the microbiological stability of the cosmetic product during the product life cycle (production, storage, use). The concentration of preservatives should be chosen to meet these goals but avoid over-preservation. As a result, the residual risk of undesired side effects (skin irritation, sensitization), which can not be completely avoided, is minimized for the user. The reduction of preservatives, however, succeeds only if ingredients of cosmetic products additionally have antimicrobial properties as a secondary property.
Konservierungsstoffe haben den Auftrag, Bakterien, Hefen und Pilzen abzutöten. Viele dieser Stoffe sind sehr reaktiv und haben cytotoxische Wirkungen, die auf der Haut zu Irritationen und Rötungen führen können. Bei langjähriger Anwendung besteht zudem ein Restrisiko für besonders empfindliche Verbraucher. Bei langjähriger Anwendung besteht zu dem die Gefahr, dass die Stoffe den Organismus sensibilisieren und es zu allergischen Reaktionen kommt. Natürlich ist die Empfindlichkeit von vielen Parametern abhängig:
Konzentration, Expositionsrate, Art der Substanz, Löslichkeitsverhalten und Ort der Anwendung. Bekannte, wenn gleich vergleichsweise schwache Allergene sind Formaldehyd und Stoffe, die im Produkt Formaldehyd freisetzen. Auch die halogenorganischen Verbindungen, zu denen einige Konservierungsmittel gehören, haben ein großes allergisches Potenzial. Preservatives are responsible for killing bacteria, yeasts and fungi. Many of these substances are very reactive and have cytotoxic effects that can cause irritation and redness on the skin. After many years of use, there is also a residual risk for particularly sensitive consumers. When used for many years there is a risk that the substances sensitize the organism and allergic reactions occur. Of course, the sensitivity depends on many parameters:
Concentration, exposure rate, nature of the substance, solubility and place of administration. Known albeit comparatively weak allergens are formaldehyde and substances which release formaldehyde in the product. The organohalogen compounds, which include some preservatives, also have great allergic potential.
Kosmetische Zubereitungen müssen jedoch langzeitstabil gegen mikrobielle Kontamination formuliert werden und trotzdem eine sehr gute Hautverträglichkeit aufweisen. However, cosmetic preparations must be formulated for long-term stability against microbial contamination and still have a very good skin compatibility.
Die mikrobielle Stabilität wird bislang durch den Zusatz an Konservierungsmitteln gelöst. Bekannte Konservierungsmittel sind die als Parabene bezeichneten Verbindungen, insbesondere 4-Hydroxybenzoesäure und deren Ester, Methylparaben, Ethylparaben, Propylparaben, Isopropylparaben, Butylparaben, Isobutylparaben, Phenylparaben. Des Weiteren ist Phenoxyethanol, Ethylenglycolmonophenylether, Phenylglycol, Phenoxetol®, zur Konservierung von kosmetischen Mitteln bekannt. The microbial stability has so far been solved by the addition of preservatives. Known preservatives are the compounds known as parabens, in particular 4-hydroxybenzoic acid and its esters, methylparaben, ethylparaben, propylparaben, isopropylparaben, butylparaben, isobutylparaben, phenylparaben. Furthermore, phenoxyethanol, ethylene glycol monophenyl ether, Phenyl, phenoxetol ®, for the preservation of cosmetic products is known.
Wünschenswert ist es daher die Menge an Konservierungsmitteln in kosmetischen oder dermatologischen Zubereitungen weitest möglich zu reduzieren. It is therefore desirable to reduce the amount of preservatives in cosmetic or dermatological preparations as much as possible.
Hinsichtlich zunehmender Gesundheitsbeeinträchtigungen und Allergien sowie dem Drang der Konsumenten nach mehr ökologisch verträglichen Kosmetika besteht das Problem, dass diese Zubereitungen dennoch eine ausreichende Stabilität und vor allem Hautverträglichkeit aufweisen müssen. Des Weiteren ist ein einfacher Austausch oder das Vermeiden von Konservierungsstoffen wie Parabene und/oder Phenoxyethanol ohne Einbußen hinsichtlich der Stabilität und Anwendungseigenschaft nicht ohne weiteres möglich. With regard to increasing health impairments and allergies and the urge of consumers for more ecologically compatible cosmetics, there is the problem that these preparations must nevertheless have sufficient stability and above all skin compatibility. Furthermore, simple replacement or avoidance of preservatives such as parabens and / or phenoxyethanol is not readily possible without sacrificing stability and performance.

Polylysin (Polylysin (ε-poly-L-lysine, EPL, CAS: 28211-04-3) ist ein Homopolymer, bestehend aus der essentiellen Aminosäure L-Lysine. Das Homopolymer wird als antimikrobielles Agens gegen Hefen, Pilze und gram-pos. und gram-neg. Bakterien beschrieben und eingesetzt. Momentan findet es als Konservierungsmittel, vor allem in Japan, Korea und den USA, Anwendung. Die Produktion erfolgt über einen fermentativen Prozess. Polylysine (polylysine (ε-poly-L-lysine, EPL, CAS: 28211-04-3) is a homopolymer consisting of the essential amino acid L-lysine, which is used as an antimicrobial agent against yeasts, fungi and gram-pos. and gram-neg bacteria are currently being used as preservatives, mainly in Japan, Korea and the US Production is via a fermentative process.
Dem Fachmann sind darüber hinaus Emulgatoren aus dem Lebensmittelbereich bekannt wie Glyceryl Stearate Citrat (Imwitor®) oder Polyglyceryl-10-Stearat. The skilled person is also known emulsifiers from the food industry such as glyceryl stearate citrate (Imwitor ® ) or polyglyceryl-10-stearate.
Auf der Suche nach geeigneten Emulgatoren, die den gewünschten Anforderungen der Kosmetik oder Dermatologie entsprechen, scheinen diese Emulgatoren sich aber auszuschließen. Glyceryl Stearate Citrat muss in kosmetischen Zubereitungen in einer solch hohen Menge oder in Kombination mit Co-Emulgatoren eingesetzt werden um stabile Emulsionen zu erhalten, so dass der Wunsch nach verringertem Emulgatorgehalt mit Glyceryl Stearate Citrat nicht zu erfüllen ist. Polyglyceryl-10-Stearat (PG-10-Stearat, CAS-Nr.: 79777-30-3) ist ein hydrophiler Emulgator und weist einen HLB von 12 auf. Im Handel sind Polyglyceryl-10-Stearate als Mischungen beispielsweise erhältlich als Polyaldo 10-1-S (Lonza), Nikkol Decaglyn 1-S (Nikko Chemicals Co., Ltd.) oder Salacos PGMSV (The Nisshin OilliO Group, Ltd.). In the search for suitable emulsifiers, which meet the desired requirements of cosmetics or dermatology, these emulsifiers but seem to exclude. Glyceryl stearate citrate must be used in cosmetic preparations in such a high amount or in combination with co-emulsifiers to obtain stable emulsions, so that the desire for reduced emulsifier content with glyceryl stearate citrate is not met. Polyglyceryl-10-stearate (PG-10 stearate, CAS No .: 79777-30-3) is a hydrophilic emulsifier and has an HLB of 12. Polyglyceryl-10-stearates are commercially available as Blends, for example, available as Polyaldo 10-1-S (Lonza), Nikkol Decaglyn 1-S (Nikko Chemicals Co., Ltd.) or Salacos PGMSV (The Nisshin OilliO Group, Ltd.).
Polyglyceryl-10-Stearat ist aus der Eiscremeherstellung bekannt und weist eine braune Farbe auf. Auch aufgrund dieses ästhetisch problematischen Umstandes schien sich die Anwendung in kosmetischen Emulsionen von selbst zu verbieten. Polyglyceryl-10-stearate is known from ice cream manufacture and has a brown color. Also due to this aesthetically problematic circumstance, the application in cosmetic emulsions seemed to ban itself.
Käuflich erwerbar ist Heliogel®, welches neben Sodium Acrylates Copolymer, Hydrogenated Polyisobutene, Phospholipids, Helianthus Annuus (Sunflower) Seed Oil auch Polyglyceryl-10-Stearate umfasst. Heliogel ® , which in addition to Sodium Acrylates Copolymer, Hydrogenated Polyisobutenes, Phospholipids, Helianthus Annuus (Sunflower) Seed Oil also contains polyglyceryl-10 stearates, is available for purchase.
In kosmetischen Zubereitungen ist PG-10-Stearat lediglich als Bestandteil eines Aftershavegels genannt. In dieser Zubereitung sind 6 Gew.% PG-10-Stearat neben weiteren Emulgatoren wie Lecithin und PEG 150 distearat beschrieben (
Überraschenderweise zeigte sich jedoch, dass sich Polyglyceryl-10-Stearat als Emulgator in kosmetischen oder dermatologischen Zubereitungen als Emulgator einsetzen lässt, ohne die Nachteile der färbenden Wirkung und der Instabilität zu zeigen. Surprisingly, however, it has been shown that polyglyceryl-10-stearate can be used as an emulsifier in cosmetic or dermatological preparations as an emulsifier, without showing the disadvantages of the coloring effect and the instability.
Überraschenderweise zeigte sich darüber hinaus, dass Polyglyceryl-10-Stearat eine verbesserte Freisetzung antimikrobieller Wirkstoffe zeigt und somit eine verbesserte Wirksamkeit ausübt. Surprisingly, it has also been shown that polyglyceryl-10-stearate shows an improved release of antimicrobial agents and thus exerts improved efficacy.
Die Erfindung ist eine kosmetische oder dermatologische Zubereitung umfassend Polyglyceryl-10-Stearat, bevorzugt weniger als 2 Gew.%, insbesondere im Bereich von 0,1 bis 1,8 Gew.%, bezogen auf die Gesamtmasse der Zubereitung, und Polylysin. The invention is a cosmetic or dermatological preparation comprising polyglyceryl-10-stearate, preferably less than 2% by weight, in particular in the range from 0.1 to 1.8% by weight, based on the total mass of the preparation, and polylysine.
Polylysin ist wasserlöslich und lässt sich daher gut in kosmetische Grundlagen einarbeiten. Aufgrund der antimikrobiellen Eigenschaften lässt sich eine verbesserte Konservierung kosmetischer oder dermatologischer Zubereitungen erzielen. Erstaunlicherweise zeigte die Kombination aus Polylysin mit Polyglycerin-10-stearat einen Synergismus hinsichtlich der antimikrobiellen Wirksamkeit. Polylysine is water-soluble and can therefore be easily incorporated into cosmetic basics. Due to the antimicrobial properties, improved preservation of cosmetic or dermatological preparations can be achieved. Surprisingly, the combination of polylysine with polyglycerol-10-stearate showed synergism for antimicrobial efficacy.
Die erfindungsgemäßen Zubereitungen basieren vorteilhaft auf einer Emulsion, bevorzugt einer O/W-Emulsion, oder Hydrodispersion. Die so hergestellten Zubereitungen, bevorzugt Emulsionen, weisen eine niedrigen Emulgatorgehalt von weniger als 2% auf und erfüllen somit den Wunsch nach gut verträglichen, milden Produkten, ohne das die Stabilität beeinträchtigt wird. Weniger als 2 Gew.% PG-10-Stearat bedeutet nicht 0 Gew.%. Bevorzugt beträgt der Mindestanteil an PG-10-Stearat 0,1 Gew.%. The preparations according to the invention are advantageously based on an emulsion, preferably an O / W emulsion, or hydrodispersion. The preparations thus prepared, preferably emulsions, have a low emulsifier content of less than 2% and thus satisfy the desire for well-tolerated, mild products without compromising stability. Less than 2% by weight of PG-10 stearate does not mean 0% by weight. The minimum proportion of PG-10 stearate is preferably 0.1% by weight.
Überraschenderweise sind die mit weniger als 2 Gew.% Polyglyceryl-10-Stearat hergestellten Zubereitungen stabil für einen Zeitraum von mindestens 3 Jahre bei Raumtemperatur und mindestens 6 Monate bei 40°C Lagerung. Des Weiteren zeigte sich überraschend, dass Polyglyceryl-10-Stearat, auch als einziger Emulgator eingesetzt, zu stabilen Emulsionen führt. Ein Verzicht auf weitere zusätzliche Emulgatoren ist damit möglich und kommt so dem Wunsch nach verringerten Emulgatorgehalten nach. Surprisingly, the preparations prepared with less than 2% by weight of polyglyceryl-10-stearate are stable for a period of at least 3 years at room temperature and at least 6 months at 40 ° C. storage. Furthermore, it was surprisingly found that polyglyceryl-10-stearate, also used as the only emulsifier, leads to stable emulsions. A waiver of further additional emulsifiers is thus possible and thus meets the desire for reduced levels of emulsifier.
Den Einsatz von PG-10-Stearat in Kosmetika auf möglichst geringe Anteile zu begrenzen mag für einen Kosmetikfachmann aufgrund der braunen Farbe des PG-10-Stearats nahe gelegen haben, jedoch müsste er aufgrund der geringen Anteile dann auch von einer verminderten emulgierenden Wirkung ausgehen. Dies hat sich bei einer Verwendung von weniger als 2 Gew.% PG-10-Stearat, insbesondere im Bereich von 0,1 bis 1,8 Gew.%, bezogen auf die Gesamtmenge der Zubereitung, überraschenderweise aber nicht bewahrheitet. In mehreren Langzeitstabilitätsuntersuchungen zeigten die PG-10-Stearat haltigen Zubereitungen keine Instabilitäten, Phasentrennung, Koaleszenz, Ostwald-Reifung oder Veränderung der Tröpfchengröße mit der Zeit oder Aufrahmung. Die Formulierungen, wie sie in den Beispielen offenbart sind, waren mindestens 6 Monate bei Raumtemperatur sowie bei 40°C optisch stabil. Das heißt es wurde keine Phasentrennung oder Phasenabscheidung beobachtet. Limiting the use of PG-10 stearate in cosmetics to the lowest possible levels may have been obvious to a cosmetic professional due to the brown color of the PG-10 stearate, but due to the low levels it would then have to emanate from a reduced emulsifying effect. However, surprisingly, this has not been confirmed when using less than 2% by weight of PG-10 stearate, in particular in the range from 0.1 to 1.8% by weight, based on the total amount of the preparation. In several long-term stability studies, the preparations containing PG-10 stearate showed no instabilities, phase separation, coalescence, Ostwald ripening, or change in droplet size over time or creaming. The formulations as disclosed in the examples were optically stable for at least 6 months at room temperature and at 40 ° C. That is, no phase separation or phase separation was observed.
In Vergleichsuntersuchungen wurde die antimikrobielle Wirksamkeit bestimmt.

Testdurchführung: Test procedure:
Die Emulgatoren wurden bei 80°C im Wasserbad erwärmt und anschließend anteilig mit PE-Wasser zur Herstellung der Emulgator/Wasser-Lösung versetzt. Für die Kombination mit Polylysin wurde festes Polylysin in der Emulgator/Wasser-Mischung gelöst. Zur Kontrolle wurde eine Probe alleinig mit Polylysin in Wasser hergestellt. Zu 500 µl der vorgelegten Wirkstofflösung wurden 500 µl Bakteriensuspension hinzugegeben und auf einem Thermoschüttler (30°C, 1200 rpm) inkubiert. Zum Testbeginn sowie nach 20 min, 60 min und 180 min werden aus den Ansätzen Proben entnommen und deren Keimzahlen auf Agarplatten bestimmt und mit Hilfe des Countermat-Instrument ausgewertet. The emulsifiers were heated at 80 ° C in a water bath and then proportionally mixed with PE water to produce the emulsifier / water solution. For the combination with polylysine, solid polylysine was dissolved in the emulsifier / water mixture. As a control, a sample was prepared solely with polylysine in water. 500 .mu.l bacterium suspension were added to 500 .mu.l of the presented drug solution and incubated on a thermo shaker (30 ° C., 1200 rpm). At the start of the test and after 20 min, 60 min and 180 min, samples are taken from the batches and their bacterial counts are determined on agar plates and evaluated using the Countermat instrument.

Durch die Kombination von PG-10-stearat mit Polylysin kommt es zu einer stärkeren Bakterien-Absterbekinetik als mit Polylysin oder PG-10-sterat allein. The combination of PG-10 stearate with polylysine leads to a stronger bacterial knock-down rate than with polylysine or PG-10-sterate alone.
Die bei anderen Emulgatorsystemen zu beobachtende Wirksamkeitsverschlechterung (durch Komplexierung etc.) findet daher scheinbar bei PG-10-stearat nicht statt. PG-10-stearat in Kombination mit Polylysin führt daher in kosmetischen oder dermatologischen Zubereitungen zu einer verbesserten Wirksamkeit hinsichtlich der antimikrobiellen Wirkung. The deterioration of activity (due to complexation, etc.) observed in other emulsifier systems therefore does not appear to occur with PG-10 stearate. PG-10 stearate in combination with polylysine therefore results in improved antimicrobial effectiveness in cosmetic or dermatological preparations.
Der Anteil an Polylysin wird vorteilhaft im Bereich von 0,1 bis 2 Gew.%, insbesondere im Bereich um 1 Gew.%, vorteilhaft im Bereich 0,8 bis 1,2 Gew.%, bezogen auf die Gesamtmasse der Zubereitung, gewählt. The proportion of polylysine is advantageously selected in the range from 0.1 to 2% by weight, in particular in the range of 1% by weight, advantageously in the range from 0.8 to 1.2% by weight, based on the total mass of the preparation.

Additional emulsifiers may be added to the preparations according to the invention. However, this is not required or mandatory in all cases according to the invention. If additional emulsifiers are added, these are preferably to be selected from the group of emulsifiers which are solid, pasty or liquid at 25 ° C and not ethoxylated.

Bevorzugt umfassen die erfindungsgemäßen Zubereitungen keinen weiteren zusätzlichen Emulgator ausser PG-10-Stearat. Der Anteil an zusätzlichen Emulgatoren sollte somit bevorzugt unter 0,01 Gew.% liegen, bezogen auf die Gesamtmasse der Zubereitung, um als erfindungsgemäß – ohne zusätzlichen Emulgator – zu gelten. The preparations according to the invention preferably comprise no further additional emulsifier except PG-10 stearate. The proportion of additional emulsifiers should therefore preferably be less than 0.01% by weight, based on the total mass of the preparation, in order to be considered to be present according to the invention-without additional emulsifier.
Zur Stabilisierung oder Verdickung von Emulsionen werden häufig Fettalkohole, wie zum Beispiel Myristylalkohol, Behenylalkohol, Stearylalkohol Palmitylalkohol usw. verwendet. Der Sammelbegriff Fettalkohole steht für einwertige primäre Alkohole mit 8 bis 22 Kohlenstoff-Atomen und verzweigten oder unverzweigten Ketten. Sie werden durch eine Reduktion der Triglyceride, Fettsäuren bzw. Fettsäuremethylester gewonnen und bilden elementare Grundstoffe zur Herstellung diverser chemischer Folgeprodukte. Was die Kettenlänge betrifft, ist eine gerade Anzahl an C-Atomen ein Kennzeichen für den natürlichen Ursprung. Fettalkohole bewirken jedoch ein charakteristisches, wachsiges, stumpfes und reichhaltiges Hautgefühl. Je nach Produkt, Zielgruppe und/oder Produktkonzept ist diese Eigenschaft aber nicht immer gewollt. Vorteilhaft sind die erfindungsgemäßen Deo-/AT-zubereitungen daher fettalkoholfrei. Fettalkoholfrei bedeutet, dass der Anteil an Fettalkoholen, insbesondere C8-22, weniger als 1 %, bezogen auf die Gesamtmasse der Zubereitung, besonders bevorzugt unter 0,25% und ganz besonders unter 0,1% beträgt. Es zeigt sich erstaunlicherweise, dass allein durch die erfindungsgemäße Wahl des PG-10-Stearat Emulgators in den Zubereitungen und Verzicht auf Fettalkohole eine breitere Variabilität hinsichtlich des einzustellenden Hautgefühls der Zubereitung erreicht werden kann. To stabilize or thicken emulsions, fatty alcohols such as myristyl alcohol, behenyl alcohol, stearyl alcohol, palmityl alcohol, etc. are often used. The generic term fatty alcohols stands for monovalent primary alcohols having 8 to 22 carbon atoms and branched or unbranched chains. They are obtained by a reduction of the triglycerides, fatty acids or fatty acid methyl esters and form elementary raw materials for the production of various chemical secondary products. As far as the chain length is concerned, an even number of C atoms is a characteristic of the natural origin. However, fatty alcohols cause a characteristic, waxy, dull and rich skin feeling. Depending on the product, target group and / or product concept, this property is not always wanted. Advantageously, the deodorant / AT preparations according to the invention are therefore free of fatty alcohols. Fatty alcohol-free means that the proportion of fatty alcohols, in particular C8-22, less than 1%, based on the total mass of the preparation, more preferably below 0.25%, and especially below 0.1%. It is surprisingly found that a broader variability can be achieved with regard to the skin feel of the formulation to be adjusted solely by the choice according to the invention of the PG-10 stearate emulsifier in the preparations and omission of fatty alcohols.
