Definitions

  • the invention is in the field of cosmetic preparations and relates to the use of nanoscale chitosans and / or chitosan derivatives in deodorant preparations.
  • deodorants are used to remove unpleasant body odors.
  • Typical examples of such substances are aluminum compounds such as aluminum sulfate or aluminum chlorohydrate, zinc salts and citric acid compounds. Since the problem of odor inhibition is by no means completely solved, there is still a need for new preparations which contain deodorants which are well tolerated by the skin and have a long-lasting effect.
  • chitosans inhibit the activity of esterase-producing bacteria and that a synergistic deodorising effect is achieved together with esterase inhibitors and aluminum chlorohydrates.
  • the chitosans have a bacteriostatic effect, i.e. the population of the affected germs is controlled, but not killed, so as not to impair the biological balance of the skin flora.
  • the effect and duration of action of the chitosans or chitosan derivatives is always related to the speed with which the compounds are incorporated or absorbed. There is still considerable room for improvement in the available state-of-the-art materials.
  • Nanoized material means spherical aggregates with a diameter in the range from approximately 1 to approximately 500 nm, which contain at least one solid or liquid core which is enclosed by at least one continuous shell.
  • Their use in cosmetics was already in 1997 by Zülli , F. and Suter, F. (Preparation and Properties of Small Nanoparticles for Skin and Hair Care, Seifen ⁇ le Fette Wwachs 123 (1997) No. 13, pp. 880, 883-885) and von Mehnert, W. et al. (Solid lipid nanoparticles. A novel carrier for cosmetics and pharmaceutics. Pharm. Ind. 59 (1997) (6), pp. 511-514).
  • the core and shell material can consist of the same or different materials.
  • the processing of excipients and active ingredients in selected formulations can be simplified by using them in the form of nanoparticles. This applies in particular to incompatibilities with other auxiliaries.
  • the release and absorption of substances can be controlled by the particle or capsule size, by using different auxiliaries or different physicochemical properties.
  • the object of the present invention was therefore to improve the distribution and absorption of the chitosans or chitosan derivatives, and at the same time to obtain a long-lasting deodorizing activity.
  • simple incorporation of the biopolymers into the formulation is to be made possible and compatibility with anionic auxiliaries is to be improved.
  • a final formulation with a pleasant skin feel, good skin tolerance and high stability should also result.
  • the invention relates to deodorant preparations which contain nanoscale chitosans and / or chitosan derivatives with a particle diameter in the range from 10 to 300 nm.
  • nanoscale chitosan leads to a long-lasting deodorizing effect
  • the absorption of chitosans or chitosan derivatives can be increased by the stratum corneum of the skin
  • the use of the nanoscale chitosans improves the manufacturability of the preparations and the compatibility with them anionic surfactants is significantly facilitated.
  • the formulations produced create a pleasant feeling on the skin and good stability.
  • the moisturizing effect of nano-chitosans counteracts possible skin drying out, particularly in the case of alcohol-containing aerosol formulations. Chitosans and chitosan derivatives
  • Chitosans are biopolymers and belong to the group of hydrocolloids. From a chemical point of view, these are partially deacetylated chitins of different molecular weights that contain the following - idealized - monomer unit:
  • chitosans is based on chitin, preferably the shell remains of crustaceans, which are available in large quantities as cheap raw materials.
  • the chitin is in a process that was first developed by Hackmann et al. has been described, usually first deproteinized by adding bases, demineralized by adding mineral acids and finally deacetylated by adding strong bases, it being possible for the molecular weights to be distributed over a broad spectrum.
  • Appropriate methods are, for example, made from Makromol. Chem. 177, 3589 (1976) or French patent application FR 2701266 A1.

  • W / O or O / W microemulsions can also be used and mixed with the non-solvent.
  • the emulsifiers and protective colloids already explained at the beginning can be used as surface-active compounds.
  • Another possibility for producing nanoparticles is the so-called GAS process (Gas Anti Solvent Recrystallization).
  • GAS process Gas Anti Solvent Recrystallization
  • the process uses a highly compressed gas or supercritical fluid (eg carbon dioxide) as a non-solvent for the crystallization of solutes.
  • the compressed gas phase is introduced into the primary solution of the starting materials and absorbed there, which increases the volume of the liquid, the solubility decreases and fine particles are separated out.

Description

Desodorierende Zubereitungen mit nanoskaligen Chitosanen und/oder ChitosanderivatenDeodorant preparations with nanoscale chitosans and / or chitosan derivatives
Gebiet der ErfindungField of the Invention
Die Erfindung befindet sich auf dem Gebiet der kosmetischen Zubereitungen und betrifft den Einsatz von nanoskaligen Chitosanen und /oder Chitosanderivaten in desodorierenden Zubereitungen.The invention is in the field of cosmetic preparations and relates to the use of nanoscale chitosans and / or chitosan derivatives in deodorant preparations.
Stand der TechnikState of the art
Im Bereich der Körperpflege werden Desodorantien zur Beseitigung störender Körpergerüche einge-setzt. Typische Beispiele für derartige Substanzen sind Aluminiumverbindungen wie Aluminiumsulfat oder Aluminiumchlorhydrat, Zinksalze und Citronensäureverbindungen. Da das Problem der Geruchsinhibierung keineswegs vollständig gelöst ist, besteht weiterhin der Bedarf an neuen Zubereitungen, die gut hautverträgliche Desodorantien mit einer langanhaltenden Wirkung enthalten.In the field of personal care, deodorants are used to remove unpleasant body odors. Typical examples of such substances are aluminum compounds such as aluminum sulfate or aluminum chlorohydrate, zinc salts and citric acid compounds. Since the problem of odor inhibition is by no means completely solved, there is still a need for new preparations which contain deodorants which are well tolerated by the skin and have a long-lasting effect.
Aus der Patentschrift DE- 19540296C2 ist bekannt, daß Chitosane die Aktivität esteraseproduzie- render Bakterien inhibieren und zusammen mit Esteraseinhibitoren und Aluminiumchlorhydraten eine synergistische desodorierende Wirkung erzielt wird. Die Chitosane wirken dabei bakteriosta- tisch, d.h. die Population der betroffenen Keime wird kontrolliert, jedoch nicht abgetötet, um das biologische Gleichgewicht der Hautflora nicht zu beeinträchtigen. Die Wirkung und Wirkungsdauer der Chitosane bzw. Chitosanderivate hängt stets mit der Geschwindigkeit zusammen, mit der die Verbindungen eingebaut bzw. resorbiert werden. Hier besteht für die verfügbaren Stoffe des Stands der Technik noch ein erhebliches Verbesserungspotential.From the patent DE-19540296C2 it is known that chitosans inhibit the activity of esterase-producing bacteria and that a synergistic deodorising effect is achieved together with esterase inhibitors and aluminum chlorohydrates. The chitosans have a bacteriostatic effect, i.e. the population of the affected germs is controlled, but not killed, so as not to impair the biological balance of the skin flora. The effect and duration of action of the chitosans or chitosan derivatives is always related to the speed with which the compounds are incorporated or absorbed. There is still considerable room for improvement in the available state-of-the-art materials.
Der allgemeine Einsatz von wasserlöslichen Chitosansalzen in Deodorantien und antibakterieller Kosmetik wurde bereits in der japanischen Patentanmeldung JP63290808 dargestellt. Es besteht jedoch Bedarf, die antibakterielle Wirkungsweise der Chitosane durch spezielle Formulierungsansätze weiterhin zu verbessern.The general use of water-soluble chitosan salts in deodorants and antibacterial cosmetics has already been described in Japanese patent application JP63290808. However, there is a need to further improve the antibacterial mode of action of the chitosans by means of special formulation approaches.
Unter „nanoisiertem Material" werden sphärische Aggregate mit einem Durchmesser im Bereich von etwa 1 bis etwa 500 nm verstanden, die mindestens einen festen oder flüssigen Kern enthalten, der von mindestens einer kontinuierlichen Hülle umschlossen ist. Ihr Einsatz in der Kosmetik wurde bereits 1997 von Zülli, F. und Suter, F. beschrieben (Preparation and Properties of Small Nanoparticles for Skin and Hair Care, Seifen Öle Fette Wachse 123 (1997) Nr. 13, S. 880, 883- 885) sowie von Mehnert, W. et al. (Solid lipid nanoparticles. A novel carrier for cosmetics and pharmaceutics. Pharm. Ind. 59 (1997) (6), S. 511-514). Dabei können Kern und Hüllmaterial aus ein und demselben oder auch aus unterschiedlichen Materialien bestehen. Die Verarbeitung von Hilfs- und Wirkstoffen in ausgewählten Formulierungen kann durch den Einsatz in Form von Nanopartikeln vereinfacht werden. Dieses gilt insbesondere bei Unverträglichkeiten mit anderen Hilfsstoffen. Desweiteren kann die Freisetzung und Absorption von Stoffen durch die Partikel- bzw. Kapselgröße, durch Einsatz unterschiedlicher Hilfsstoffe oder unterschiedliche physikalischchemische Eigenschaften gesteuert werden.“Nanoized material” means spherical aggregates with a diameter in the range from approximately 1 to approximately 500 nm, which contain at least one solid or liquid core which is enclosed by at least one continuous shell. Their use in cosmetics was already in 1997 by Zülli , F. and Suter, F. (Preparation and Properties of Small Nanoparticles for Skin and Hair Care, Seifen Öle Fette Wwachs 123 (1997) No. 13, pp. 880, 883-885) and von Mehnert, W. et al. (Solid lipid nanoparticles. A novel carrier for cosmetics and pharmaceutics. Pharm. Ind. 59 (1997) (6), pp. 511-514). The core and shell material can consist of the same or different materials. The processing of excipients and active ingredients in selected formulations can be simplified by using them in the form of nanoparticles. This applies in particular to incompatibilities with other auxiliaries. Furthermore, the release and absorption of substances can be controlled by the particle or capsule size, by using different auxiliaries or different physicochemical properties.
In den Patentschriften US 5194262 und US 5271934 werden Mikrokapseln, die Antiperspirantien ummanteln, dargestellt. Durch Bestandteile der Hülle oder auch zusätzliche Überzüge erhalten diese bioadhesive Eigenschaften und tragen so zu einer langanhaltenden Wirkung bei.In the patents US 5194262 and US 5271934 microcapsules that encase antiperspirants are shown. Components of the shell or additional coatings give these bioadhesive properties and thus contribute to a long-lasting effect.
Die Aufgabe der vorliegenden Erfindung hat somit darin bestanden, die Verteilung und Aufnahme der Chitosane bzw. Chitosanderivate zu verbessern, und gleichzeitig eine langanhaltende desodorierende Wirksamkeit zu erhalten. Zusätzlich soll eine einfache Einarbeitung der Biopolymere in die Formulierung ermöglicht werden und die Kompatibilität mit anionischen Hilfsstoffen verbessert werden. Es soll weiterhin eine Endformulierung mit angenehmem Hautgefühl, guter Hautverträglichkeit und hoher Stabilität resultieren.The object of the present invention was therefore to improve the distribution and absorption of the chitosans or chitosan derivatives, and at the same time to obtain a long-lasting deodorizing activity. In addition, simple incorporation of the biopolymers into the formulation is to be made possible and compatibility with anionic auxiliaries is to be improved. A final formulation with a pleasant skin feel, good skin tolerance and high stability should also result.
Beschreibung der ErfindungDescription of the invention
Gegenstand der Erfindung sind desodorierende Zubereitungen, die nanoskalige Chitosane und/oder Chitosanderivate mit einem Teilchendurchmesser im Bereich von 10 bis 300 nm enthalten.The invention relates to deodorant preparations which contain nanoscale chitosans and / or chitosan derivatives with a particle diameter in the range from 10 to 300 nm.
Überraschenderweise wurde gefunden, daß der Einsatz von nanoskaligem Chitosan zu einer langanhaltenden desodorierenden Wirkung führt, sich die Resorption von Chitosanen bzw. Chitosanderivaten durch das Stratum Corneum der Haut steigern läßt, und zudem durch den Einsatz der nanoskaligen Chitosane die Herstellbarkeit der Zubereitungen sowie die Verträglichkeit mit anionischen Tensiden wesentlich erleichtert wird. Die hergestellten Formulierungen bewirken ein angenehmes Hautgefühl und eine gute Stabilität. Die Moisturizerwirkung von Nano-Chitosanen wirkt insbesondere bei alkoholhaltigen Aerosolformulierungen einer möglichen Hautaustrocknung entgegen. Chitosane und ChitosanderivateSurprisingly, it was found that the use of nanoscale chitosan leads to a long-lasting deodorizing effect, the absorption of chitosans or chitosan derivatives can be increased by the stratum corneum of the skin, and also the use of the nanoscale chitosans improves the manufacturability of the preparations and the compatibility with them anionic surfactants is significantly facilitated. The formulations produced create a pleasant feeling on the skin and good stability. The moisturizing effect of nano-chitosans counteracts possible skin drying out, particularly in the case of alcohol-containing aerosol formulations. Chitosans and chitosan derivatives
Chitosane stellen Biopolymere dar und werden zur Gruppe der Hydrokolloide gezählt. Chemisch betrachtet handelt es sich um partiell deacetylierte Chitine unterschiedlichen Molekulargewichtes, die den folgenden - idealisierten - Monomerbaustein enthalten:Chitosans are biopolymers and belong to the group of hydrocolloids. From a chemical point of view, these are partially deacetylated chitins of different molecular weights that contain the following - idealized - monomer unit:
Zur Herstellung der Chitosane geht man von Chitin, vorzugsweise den Schalenresten von Krustentieren aus, die als billige Rohstoffe in großen Mengen zur Verfügung stehen. Das Chitin wird dabei in einem Verfahren das erstmals von Hackmann et al. beschrieben worden ist, üblicherweise zunächst durch Zusatz von Basen deproteiniert, durch Zugabe von Mineralsäuren demineralisiert und schließlich durch Zugabe von starken Basen deacetyliert, wobei die Molekulargewichte über ein breites Spektrum verteilt sein können. Entsprechende Verfahren sind beispielsweise aus Makromol. Chem. 177, 3589 (1976) oder der französischen Patentanmeldung FR 2701266 A1 bekannt. Vorzugsweise werden solche Typen eingesetzt, wie sie in den deutschen Patentanmeldungen DE 4442987 A1 und DE 19537001 A1 (Henkel) offenbart werden, und die ein durchschnittliches Molekulargewicht von 800.000 bis 1.200.000 Dalton, eine Viskosität nach Brookfield (1 Gew.-%ig in Glycolsäure) unterhalb von 5000 mPas, einen Deacetylierungsgrad im Bereich von 80 bis 88 % und einem Aschegehalt von weniger als 0,3 Gew.-% aufweisen. Neben den Chitosanen als typischen kationischen Biopolymeren kommen im Sinne der Erfindung auch anionisch, nichtionisch oder kationisch derivatisierte Chitosane, wie z.B. Carboxylierungs-, Succinylierungs-, Alkoxylierungs- oder Quaternierungsprodukte in Frage, wie sie beispielsweise in der deutschen Patentschrift DE 3713099 C2 sowie der deutschen Patentanmeldung DE 19604180 A1 beschrieben werden.The production of chitosans is based on chitin, preferably the shell remains of crustaceans, which are available in large quantities as cheap raw materials. The chitin is in a process that was first developed by Hackmann et al. has been described, usually first deproteinized by adding bases, demineralized by adding mineral acids and finally deacetylated by adding strong bases, it being possible for the molecular weights to be distributed over a broad spectrum. Appropriate methods are, for example, made from Makromol. Chem. 177, 3589 (1976) or French patent application FR 2701266 A1. Such types are preferably used, as are disclosed in German patent applications DE 4442987 A1 and DE 19537001 A1 (Henkel), and which have an average molecular weight of 800,000 to 1,200,000 Daltons, a viscosity according to Brookfield (1% by weight in Glycolic acid) below 5000 mPas, a degree of deacetylation in the range from 80 to 88% and an ash content of less than 0.3% by weight. In addition to the chitosans as typical cationic biopolymers, anionically, nonionically or cationically derivatized chitosans, such as e.g. Carboxylation, succinylation, alkoxylation or quaternization products, such as are described, for example, in German patent DE 3713099 C2 and German patent application DE 19604180 A1.
Herstellung von NanopartikelnManufacture of nanoparticles
Ein Verfahren zur Herstellung von Nanoteilchen durch rasche Entspannung von überkritischen Lösungen (Rapid Expansion of Supercritical Solutions RESS) ist beispielsweise aus dem Aufsatz von S.Chihlar, M.Türk und K.Schaber in Proceedings World Congress on Particle Technology 3, Brighton, 1998 bekannt, in einer bevorzugten Ausführungsform der Erfindung setzt man nanoskalige Chitosane und/oder Chitosanderivate ein, die man erhält, indem manA process for the production of nanoparticles by rapid relaxation of supercritical solutions (RESS) is known, for example, from the article by S.Chihlar, M.Türk and K. Schaber in Proceedings World Congress on Particle Technology 3, Brighton, 1998 , in a preferred embodiment of the invention one includes nanoscale chitosans and / or chitosan derivatives, which are obtained by
(a) die Ausgangsstoffe unter überkritischen oder nahekritischen Bedingungen in einem geeigneten Lösungsmittel löst,(a) dissolving the starting materials in a suitable solvent under supercritical or near-critical conditions,
(b) die fluide Mischung über eine Düse in ein Vakuum, ein Gas oder eine Flüssigkeit entspannt, und(b) the fluid mixture is expanded into a vacuum, gas or liquid via a nozzle, and
(c) das Lösemittel dabei gleichzeitig verdampft.(c) the solvent evaporates at the same time.
Um zu verhindern, daß die Nanoteilchen wieder zusammenbacken, empfiehlt es sich, die Ausgangsstoffe in Gegenwart geeigneter Schutzkolloide oder Emulgatoren zu lösen und/oder die kritischen Lösungen in wäßrige und/oder alkoholische Lösungen der Schutzkolloide bzw. Emulgatoren oder aber in kosmetische Öle zu entspannen, welche ihrerseits wieder gelöste Emulgatoren und/oder Schutzkolloide enthalten können. Geeignete Schutzkolloide sind dabei z.B. Gelatine, Ca- sein, Gummi arabicum, Lysalbinsäure, Stärke sowie Polymere, wie etwa Polyvinylalkohole, Polyvi- nylpyrrolidone Polyalkylenglycole und Polyacrylate. Die bevorzugt zu verwendenden nanoskaligen Chitosane bzw. Chitosanderivate sind also die, die von einem Schutzkolloid und/oder einem Emul- gator ummantelt vorliegen. Üblicherweise werden die Schutzkolloide oder Emulgatoren in Mengen von 0,1 bis 20, vorzugsweise 5 bis 15 Gew.-% - bezogen auf die Chitosane und/oder Chitosanderivate - eingesetzt.In order to prevent the nanoparticles from caking again, it is advisable to dissolve the starting materials in the presence of suitable protective colloids or emulsifiers and / or to relax the critical solutions in aqueous and / or alcoholic solutions of the protective colloids or emulsifiers or in cosmetic oils, which in turn can contain dissolved emulsifiers and / or protective colloids. Suitable protective colloids are e.g. Gelatin, casein, gum arabic, lysalbic acid, starch and polymers, such as polyvinyl alcohols, polyvinyl pyrrolidones, polyalkylene glycols and polyacrylates. The preferred nanoscale chitosans or chitosan derivatives to be used are therefore those which are encased in a protective colloid and / or an emulsifier. The protective colloids or emulsifiers are usually used in amounts of 0.1 to 20, preferably 5 to 15% by weight, based on the chitosans and / or chitosan derivatives.
Ein weiteres geeignetes Verfahren zur Herstellung der nanoskaligen Teilchen bietet die Evaporati- ons-technik. Hierbei werden die Chitosane in einer geeigneten verdünnten organischen Säure oder Mineralsäure, beispielsweise Glycolsäure, Milchsäure oder Salzsäure bei pH-Werten zwischen 1 und 5 gelöst. Die Lösung wird in ein Nichtlösungsmittel für die Chitosane (z.B. Alkane, pflanzliche Öle, kosmetische Öle, Ether, Ester, Ketone, Acetale und dergleichen) gegeben, welches u.U. eine oberflächenaktive Verbindung enthält. Durch die Vermischung der beiden Systeme kommt es zu einer Ausfällung der Nanoteilchen, wobei man vorzugsweise die wäßrige Phase verdampft. Anstelle der wäßrigen Lösungen können auch W/O- oder O/W-Mikroemulsionen eingesetzt und mit dem Nicht-Lösungsmittel vermischt werden. Als oberflächenaktive Verbindungen können die bereits eingangs erläuterten Emulgatoren und Schutzkolloide verwendet werden. Eine weitere Möglichkeit zur Herstellung von Nanoteilchen besteht in dem sogenannten GAS-Verfahren (Gas Anti Solvent Recrystallization). Das Verfahren nutzt ein hochkomprimiertes Gas oder überkritisches Fluid (z.B. Kohlendioxid) als Nicht-Lösungsmittel zur Kristallisation von gelösten Stoffen. Die verdichtete Gasphase wird in die Primärlösung der Ausgangsstoffe eingeleitet und dort absorbiert, wodurch sich das Flüssigkeitsvolumen vergrößert, die Löslichkeit abnimmt und feinteilige Partikel ausgeschieden werden. Ähnlich geeignet ist das PCA-Verfahren (Precipitation with a Compressed Fluid Anti-Solvent). Hier wird die Primärlösung der Ausgangsstoffe in ein überkritisches Fluid eingeleitet, wobei sich feinstverteilte Tröpfchen bilden, in denen Diffusionsvorgänge ablaufen, so daß eine Ausfällung feinster Partikel erfolgt. Beim PGSS-Verfahren (Particles from Gas Saturated Solutions) werden die Ausgangsstoffe durch Aufpressen von Gas (z.B. Kohlendioxid oder Propan) aufgeschmolzen. Druck und Temperatur erreichen nahe- oder überkritische Bedingungen. Die Gasphase löst sich im Feststoff und bewirkt eine Absenkung der Schmelztemperatur, der Viskosität und der Oberflächenspannung. Bei der Expansion durch eine Düse kommt es durch Abkühlungseffekte zur Bildung feinster Teilchen.Evaporation technology offers another suitable method for producing the nanoscale particles. Here, the chitosans are dissolved in a suitable dilute organic acid or mineral acid, for example glycolic acid, lactic acid or hydrochloric acid at pH values between 1 and 5. The solution is placed in a non-solvent for the chitosans (eg alkanes, vegetable oils, cosmetic oils, ethers, esters, ketones, acetals and the like), which may contain a surface-active compound. The mixing of the two systems leads to precipitation of the nanoparticles, the aqueous phase preferably being evaporated. Instead of the aqueous solutions, W / O or O / W microemulsions can also be used and mixed with the non-solvent. The emulsifiers and protective colloids already explained at the beginning can be used as surface-active compounds. Another possibility for producing nanoparticles is the so-called GAS process (Gas Anti Solvent Recrystallization). The process uses a highly compressed gas or supercritical fluid (eg carbon dioxide) as a non-solvent for the crystallization of solutes. The compressed gas phase is introduced into the primary solution of the starting materials and absorbed there, which increases the volume of the liquid, the solubility decreases and fine particles are separated out. The PCA method (Precipitation with a Compressed Fluid Anti-Solvent) is similarly suitable. Here the primary solution of the starting materials is introduced into a supercritical fluid, whereby finely divided droplets form in which diffusion processes take place run off, so that fine particles are precipitated. In the PGSS process (Particles from Gas Saturated Solutions), the starting materials are melted by injecting gas (e.g. carbon dioxide or propane). Pressure and temperature reach near or supercritical conditions. The gas phase dissolves in the solid and causes a lowering of the melting temperature, the viscosity and the surface tension. When expanding through a nozzle, cooling effects lead to the formation of very fine particles.
Gewerbliche AnwendbarkeitIndustrial applicability
Gegenüber Chitosanen und Chitosanderivaten des Stands der Technik bewirkt die besondere Feinteiligkeit der Partikel einerseits ein rascheres Eindringen in das Stratum Corneum, andererseits durch die langsame Auflösung am Wirkort auch einen langanhaltenden deodorierenden Effekt. Die Einsatzmenge der nanoskaligen Verbindungen liegt üblicherweise in der Größenordnung von 0,01 bis 5 Gew. %, vorzugsweise 0,1 bis 1 Gew. % und insbesondere 0,2 bis 0,6 Gew.-% - bezogen auf die Zubereitungen.Compared to chitosans and chitosan derivatives of the prior art, the particular fine particle size of the particles on the one hand results in a faster penetration into the stratum corneum, and on the other hand also a long-lasting deodorising effect due to the slow dissolution at the site of action. The amount of nanoscale compounds used is usually on the order of 0.01 to 5% by weight, preferably 0.1 to 1% by weight and in particular 0.2 to 0.6% by weight, based on the preparations.

Esteraseinhibitorenesterase
Beim Vorhandensein von Schweiß im Achselbereich werden durch Bakterien extrazelluläre Enzyme - Esterasen, vorzugsweise Proteasen und/oder Lipasen - gebildet, die im Schweiß enthaltene Ester spalten und dadurch Geruchsstoffe freisetzen. Esteraseinhibitoren der Komponente, vorzugsweise Trialkylcitrate wie Trimethylcitrat, Tripropylcitrat, Triisopropylcitrat, Tributylcitrat und insbesondere Triethylcitrat (Hydagen® CAT, Cognis GmbH, Düsseldorf/FRG). Die Stoffe inhibieren die Enzymaktivität und reduzieren dadurch die Geruchsbildung. Wahrscheinlich wird dabei durch die Spaltung des Citronensäureesters die freie Säure freigesetzt, die den pH-Wert auf der Haut soweit absenkt, daß dadurch die Enzyme durch Acylierung inaktiviert werden. Weitere Stoffe, die als Esteraseinhibitoren in Betracht kommen, sind Sterolsulfate oder - phosphate, wie beispielsweise Lanosterin-, Cholesterin-, Campesterin-, Stigmasterin- und Sitosterinsulfat bzw -phosphat, Dicarbonsäuren und deren Ester, wie beispielsweise Glutarsäure, Glutarsäuremonoethylester, Glutarsäurediethylester, Adipinsäure, Adipinsäuremonoethylester, Adipinsäurediethylester, Malonsaure und Malonsäurediethylester, Hydroxycarbonsäuren und deren Ester wie beispielsweise Citronensäure, Äpfelsäure, Weinsäure oder Weinsäurediethylester sowie Zinkglycinat.In the presence of sweat in the armpit area, bacteria form extracellular enzymes - esterases, preferably proteases and / or lipases - which cleave esters contained in sweat and thereby release odorous substances. Esterase inhibitors of the component, preferably trialkyl citrates such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and in particular triethyl citrate (Hydagen® CAT, Cognis GmbH, Dusseldorf / FRG). The substances inhibit enzyme activity and thereby reduce odor. The cleavage of the citric acid ester probably releases the free acid, which lowers the pH value on the skin to such an extent that the enzymes are inactivated by acylation. Further substances which can be considered as esterase inhibitors are sterolsulfates or - phosphates, such as, for example, lanosterol, cholesterol, campesterin, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and their esters, such as, for example, glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, Monoethyl adipate, diethyl adipate, diethyl malonate and diethyl malonate, hydroxycarboxylic acids and their esters such as, for example, citric acid, malic acid, tartaric acid or diethyl tartarate and zinc glycinate.

Weiterhin können als Emulgatoren zwitterionische Tenside verwendet werden. Als zwitterionische Tenside werden solche oberflächenaktiven Verbindungen bezeichnet, die im Molekül mindestens eine quartäre Ammoniumgruppe und mindestens eine Carboxylat- und eine Sulfonatgruppe tragen. Besonders geeignete zwitterionische Tenside sind die sogenannten Betaine wie die N-Alkyl-N,N- dimethylammoniumglycinate, beispielsweise das Kokosalkyldimethylammoniumglycinat, N-Acyl- aminopropyl-N,N-dimethylammoniumglycinate, beispielsweise das Kokosacylaminopropyl- dimethylammoniumglycinat, und 2-Alkyl-3-carboxylmethyl-3-hydroxyethylimidazoline mit jeweils 8 bis 18 C-Atomen in der Alkyl- oder Acylgruppe sowie das Kokosacylaminoethylhydroxyethyl- carboxymethylglycinat. Besonders bevorzugt ist das unter der CTFA-Bezeichnung Cocamidopropyl Betaine bekannte Fettsäureamid-Derivat. Ebenfalls geeignete Emulgatoren sind ampholytische Tenside. Unter ampholytischen Tensiden werden solche oberflächenaktiven Verbindungen verstanden, die außer einer Cs/iβ-Alkyl- oder -Acylgruppe im Molekül mindestens eine freie Aminogruppe und mindestens eine -COOH- oder -Sθ3H-Gruppe enthalten und zur Ausbildung innerer Salze befähigt sind. Beispiele für geeignete ampholytische Tenside sind N-Alkylglycine, N- Alkylpropionsäuren, N-Alkylaminobuttersäuren, N-Alkyliminodipropionsäuren, N-Hydroxyethyl-N- alkylamidopropylglycine, N-Alkyltaurine, N-Alkylsarcosine, 2-Alkylaminopropionsäuren und Alkylaminoessigsäuren mit jeweils etwa 8 bis 18 C-Atomen in der Alkylgruppe.

Zwitterionic surfactants are surface-active compounds that contain at least one quaternary ammonium group and at least one carboxylate and one sulfonate group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines such as the N-alkyl-N, N-dimethylammonium glycinate, for example the cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N, N-dimethylammonium glycinate, for example the cocoacylaminopropyldimethylammonium glycinate, and 2-alkyl-3-carboxyl -3-hydroxyethylimidazolines each having 8 to 18 carbon atoms in the alkyl or acyl group and the cocoacylaminoethylhydroxyethylcarboxymethylglycinate. The fatty acid amide derivative known under the CTFA name of Cocamidopropyl Betaine is particularly preferred. Suitable emulsifiers are ampholytic surfactants. Ampholytic surfactants are surface-active compounds which, in addition to a Cs / iβ-alkyl or -acyl group, contain at least one free amino group and at least one -COOH or -Sθ3H group in the molecule and are capable of forming internal salts. Examples of suitable ampholytic surfactants are N-alkylglycine, N-alkylpropionic acid, N-alkylaminobutyric acid, N-alkyliminodipropionic acid, N-hydroxyethyl-N-alkylamidopropylglycine, N-alkyltaurine, N-alkyl sarcosine, 2-alkylaminopropionic acid and Alkylaminoacetic acids each with about 8 to 18 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-coconut alkylaminopropionate, coconut acylaminoethyl laminopropionate and Ci2 / i8 acyl sarcosine. Finally, cationic surfactants are also suitable as emulsifiers, those of the esterquat type, preferably methylquaternized di-fatty acid triethanolamine ester salts, being particularly preferred.
Fette und WachseFats and waxes
Typische Beispiele für Fette sind Glyceride, d.h. feste oder flüssige pflanzliche oder tierische Produkte, die im wesentlichen aus gemischten Glycerinestem höherer Fettsäuren bestehen, als Wachse kommen u.a. natürliche Wachse, wie z.B. Candelillawachs, Carnaubawachs, Japanwachs, Espartograswachs, Korkwachs, Guarumawachs, Reiskeimölwachs, Zuckerrohrwachs, Ouricurywachs, Montanwachs, Bienenwachs, Schellackwachs, Walrat, Lanolin (Wollwachs), Bürzelfett, Ceresin, Ozokerit (Erdwachs), Petrolatum, Paraffinwachse, Mikrowachse; chemisch modifizierte Wachse (Hartwachse), wie z.B.

Weiterhin kommen Guerbetalkohole mit 20 bis 54, vorzugsweise 30 bis 46 Kohlenstoffen in Frage. Neben den Fetten kommen als Zusatzstoffe auch fettähnliche Substanzen, wie Lecithine und Phospholipide in Frage. Unter der Bezeichnung Lecithine versteht der Fachmann diejenigen Gly- cero-Phospholipide, die sich aus Fettsäuren, Glycerin, Phosphorsäure und Cholin durch Veresterung bilden. Lecithine werden in der Fachwelt daher auch häufig als Phosphatidylcholine (PC) bezeichnet und folgen der allgemeinen FormelTypical examples of fats are glycerides, i.e. Solid or liquid vegetable or animal products, which consist essentially of mixed glycerol esters of higher fatty acids, come as waxes, among others. natural waxes, e.g. Candelilla wax, carnauba wax, Japanese wax, esparto grass wax, cork wax, guaruma wax, rice germ oil wax, sugar cane wax, ouricury wax, montan wax, beeswax, shellac wax, walnut, lanolin (wool wax), pretzel fat, ceresin, ozokerite (earth wax), petrolatum, paraffin waxes, microfax waxes chemically modified waxes (hard waxes), e.g. Montanester waxes, Sasol waxes, hydrogenated jojoba waxes and synthetic waxes, such as Polyalkylene waxes and polyethylene glycol waxes in question. Guerbet alcohols with 20 to 54, preferably 30 to 46 carbons are also suitable. In addition to fats, fat-like substances such as lecithins and phospholipids can also be used as additives. The term “lecithins” is understood by the person skilled in the art to mean those glycerophospholipids which are formed from fatty acids, glycerol, phosphoric acid and choline by esterification. Lecithins are therefore often referred to in the art as phosphatidylcholines (PC) and follow the general formula
wobei R typischerweise für lineare aliphatische Kohlenwasserstoffreste mit 15 bis 17 Kohlenstoffatomen und bis zu 4 cis-Doppelbindungen steht. Als Beispiele für natürliche Lecithine seien die Kephaline genannt, die auch als Phosphatidsäuren bezeichnet werden und Derivate der 1 ,2- Diacyl-sn-glycerin-3-phosphorsäuren darstellen. Dem gegenüber versteht man unter Phospholipiden gewöhnlich Mono- und vorzugsweise Diester der Phosphorsäure mit Glycerin (Glycerinphosphate), die allgemein zu den Fetten gerechnet werden. Daneben kommen auch Sphingosine bzw. Sphingolipide in Frage. %where R typically represents linear aliphatic hydrocarbon radicals with 15 to 17 carbon atoms and up to 4 cis double bonds. Examples of natural lecithins are the cephalins, which are also referred to as phosphatidic acids and are derivatives of 1,2-diacyl-sn-glycerol-3-phosphoric acids. In contrast, phospholipids are usually understood to be mono- and preferably diesters of phosphoric acid with glycerol (glycerol phosphates), which are generally classed as fats. In addition, sphingosines or sphingolipids are also suitable. %

Zusätzliche Deodorantien und keimhemmende MittelAdditional deodorants and germicides
Kosmetische Deodorantien (Desodorantien) wirken Körpergerüchen entgegen, überdecken oder beseitigen sie. Körpergerüche entstehen durch die Einwirkung von Hautbakterien auf apokrinen Schweiß, wobei unangenehm riechende Abbauprodukte gebildet werden. Dementsprechend enthalten Deodorantien Wirkstoffe, die als keimhemmende Mittel, Enzyminhibitoren, Geruchsabsorber oder Geruchsüberdecker fungieren. Als keimhemmende Mittel sind grundsätzlich alle gegen grampositive Bakterien wirksamen Stoffe geeignet, wie z. B. 4-Hydroxybenzoesäure und ihre Salze und Ester, N-(4-Chlorphenyl)-N'-(3,4 dichlorphenyl)harnstoff, 2,4,4'-Trichlor-2'-hydroxy- diphenylether (Triclosan), 4-Chlor-3,5-dimethylphenol, 2,2'-Methylen-bis(6-brom-4-chlorphenol), 3- Methyl-4-(1 -methylethyl)phenol, 2-Benzyl-4-chlorphenol, 3-(4-Chlorphenoxy)-1 ,2-propandiol, 3-lod- 2-propinylbutylcarbamat, Chlorhexidin, 3,4,4 '-Trichlorcarbanilid (TTC), antibakterielle Riechstoffe, Thymol, Thymianöl, Eugenol, Nelkenöl, Menthol, Minzöl, Famesol, Phenoxyethanol, Glycerinmono- caprinat, Glycerinmonocaprylat, Glycerinmonolaurat (GML), Diglycerinmonocaprinat (DMC), Sali- cylsäure-N-alkylamide wie z. B. Salicylsäure-n-octylamid oder Salicylsäure-n-decylamid. Üblicherweise liegt der Anteil der zusätzlichen keimhemmenden Mittel bei etwa 0,1 bis 2 Gew.-% - bezogen auf den auf den Feststoffanteil der Zubereitungen.Cosmetic deodorants counteract, mask or eliminate body odors. Body odors arise from the action of skin bacteria on apocrine sweat, whereby unpleasant smelling breakdown products are formed. Accordingly, deodorants contain active ingredients which act as germ-inhibiting agents, enzyme inhibitors, odor absorbers or odor maskers. In principle, all substances effective against gram-positive bacteria are suitable as germ-inhibiting agents, such as. B. 4-hydroxybenzoic acid and its salts and esters, N- (4-chlorophenyl) -N ' - (3,4 dichlorophenyl) urea, 2,4,4 ' -Trichlor-2 ' -hydroxy-diphenyl ether (triclosan), 4th chloro-3,5-dimethylphenol, 2,2 '-methylene-bis (6-bromo-4-chlorophenol), 3-methyl-4- (1-methylethyl) phenol, 2-benzyl-4-chlorophenol, 3- (4-chlorophenoxy) -1, 2-propanediol, 3-iodo-2-propynyl butyl carbamate, chlorhexidine, 3,4,4 ' trichlorocarbanilide (TTC), antibacterial fragrances, thymol, thyme oil, eugenol, clove oil, menthol, mint oil, famesol , Phenoxyethanol, glycerol monocaprinate, glycerol monocaprylate, glycerol monolaurate (GML), diglycerol monocaprinate (DMC), salicylic acid N-alkylamides such as, for. B. salicylic acid-n-octylamide or salicylic acid-n-decylamide. The proportion of the additional germ-inhibiting agents is usually about 0.1 to 2% by weight, based on the solids content of the preparations.
Als Geruchsabsorber eignen sich Stoffe, die geruchsbildende Verbindungen aufnehmen und weitgehend festhalten können. Sie senken den Partialdruck der einzelnen Komponenten und verringern so auch ihre Ausbreitungsgeschwindigkeit. Wichtig ist, daß dabei Parfüms unbeeinträchtigt bleiben müssen. Geruchsabsorber haben keine Wirksamkeit gegen Bakterien. Sie enthalten beispielsweise als Hauptbestandteil ein komplexes Zinksalz der Ricinolsäure oder spezielle, weitgehend geruchsneutrale Duftstoffe, die dem Fachmann als "Fixateure" bekannt sind, wie z. B. Extrakte von Labdanum bzw. Styrax oder bestimmte Abietinsäurederivate. Als Geruchsüberdecker fungieren Riechstoffe oder Parfümöle, die zusätzlich zu ihrer Funktion als Geruchsüberdecker den Deodorantien ihre jeweilige Duftnote verleihen. Als Parfümöle seien beispielsweise genannt Gemische aus natürlichen und synthetischen Riechstoffen. Natürliche Riechstoffe sind Extrakte von Blüten, Stengeln und Blättern, Früchten, Fruchtschalen, Wurzeln, Hölzern, Kräutern und Gräsern, ?Suitable odor absorbers are substances that absorb odor-forming compounds and can retain them to a large extent. They lower the partial pressure of the individual components and thus also reduce their speed of propagation. It is important that perfumes must remain unaffected. Odor absorbers are not effective against bacteria. They contain, for example, a complex zinc salt of ricinoleic acid or special, largely odorless fragrances, which are known to the person skilled in the art as "fixators", such as, for example, the main component. B. extracts of Labdanum or Styrax or certain abietic acid derivatives. Fragrance agents or perfume oils act as odor maskers, which, in addition to their function as odor maskers, give the deodorants their respective fragrance. Perfume oils are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts of flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, ?
Nadeln und Zweigen sowie Harzen und Balsamen. Weiterhin kommen tierische Rohstoffe in Frage, wie beispielsweise Zibet und Castoreum.

Als Farbstoffe können die für kosmetische Zwecke geeigneten und zugelassenen Substanzen verwendet werden, wie sie beispielsweise in der Publikation "Kosmetische Färbemittel" der Farbstoffkommission der Deutschen Forschungsgemeinschaft, Verlag Chemie, Weinheim, 1984, S.81-106 zusammengestellt sind. Diese Farbstoffe werden üblicherweise in Konzentrationen von 0,001 bis 0,1 Gew.-%, bezogen auf die gesamte Mischung, eingesetzt. BeispieleThe dyes which can be used are those substances which are suitable and approved for cosmetic purposes, as compiled, for example, in the publication "Cosmetic Dyes" by the Dye Commission of the German Research Foundation, Verlag Chemie, Weinheim, 1984, pp. 81-106. These dyes are usually used in concentrations of 0.001 to 0.1% by weight, based on the mixture as a whole. Examples
Herstellung der nanoskaligen Chitosane und ChitosanderivateProduction of the nanoscale chitosans and chitosan derivatives
Es wurde in den Beispielen 1 und 2 zunächst Kohlendioxid einem Reservoir mit einem konstanten Druck von 60 bar entnommen und über eine Kolonne mit einer Aktivkohle- und einer Molekularsieb-Packung gereinigt. Nach der Verflüssigung wurde das CO2 mit Hilfe einer Diaphragma-Pumpe bei einer konstanten Fördermenge von 3,5 l/h auf den gewünschten überkritischen Druck p verdichtet. Anschließend wurde das Lösungsmittel in einem Vorheizer auf die erforderliche Temperatur T1 gebracht und in eine Extraktionskolonne (Stahl, 400 ml) geleitet, welche mit dem Chitosan bzw. Chitosanderivat beladen war. Die resultierende überkritische, d.h. fluide Mischung wurde über eine lasergezogene Düse (Länge 830 μm, Durchmesser 45 μm) bei einer Temperatur T2 in eine Plexiglas Expansionskammer versprüht, die eine 4 Gew.-%ige wäßrige Lösung eines Emulgators bzw. Schutzkolloids enthielt. Das fluide Medium verdampfte und zurück blieben die im Schutzkolloid eingeschlossenen, dispergierten Nanopartikel. Die Verfahrensbedingungen und der mittlere Partikelgrößenbereich (PGB, photometrisch nach der 3- WEM-Methode bestimmt) sind in der nachfolgenden Tabelle 1 angegeben.In Examples 1 and 2, carbon dioxide was first taken from a reservoir at a constant pressure of 60 bar and cleaned over a column with an activated carbon and a molecular sieve packing. After liquefaction, the CO2 was compressed to the desired supercritical pressure p using a diaphragm pump at a constant flow rate of 3.5 l / h. The solvent was then brought to the required temperature T1 in a preheater and passed into an extraction column (steel, 400 ml) which was loaded with the chitosan or chitosan derivative. The resulting supercritical, i.e. The fluid mixture was sprayed through a laser-drawn nozzle (length 830 μm, diameter 45 μm) at a temperature T2 into a plexiglass expansion chamber which contained a 4% by weight aqueous solution of an emulsifier or protective colloid. The fluid medium evaporated and the dispersed nanoparticles enclosed in the protective colloid remained. The process conditions and the mean particle size range (PGB, determined photometrically by the 3-WEM method) are given in Table 1 below.
