Definitions
- the present invention relates to cosmetic or dermatological compositions for the cosmetic and topical dermatological skin whitening or to the prevention of tanning of the skin, in particular the skin tanning caused by UV radiation, as well as for lightening keratinic fibers, in particular the natural human hair color.
- melanocytes which are found in the lowest layer of the epidermis in addition to the basal cells as either isolated or frequently occurring pigment-forming cells depending on the skin type.
- Melanocytes contain melanosomes in which melanin is formed. Through various chemical and / or physical influences, in particular by UV radiation, melanin is increasingly formed. This is transported via the keratinocytes into the corneocytes (horny layer) and leads to a brownish to brown-black skin color.
- Melanin is formed as the final stage of an oxidative process in which tyrosine is converted by means of the enzyme tyrosinase via several intermediates to the brown to brown-black eumelanins (DHICA and DHI melanin) or with the involvement of sulfur-containing compounds to the reddish phaeomelanin.
- DHICA and DHI melanin brown to brown-black eumelanins
- melanin-producing melanocytes are responsible for the hair color.
- the amount and composition of melanin in hair determines the natural hair color that is genetically determined.

Description
"Hautaufhellende Zusammensetzungen mit verbesserter Wirkung""Skin lightening compositions with improved effect"
Die vorliegende Erfindung betrifft kosmetische oder dermatologische Zusammensetzungen zur kosmetischen und topischen dermatologischen Hautaufhellung oder zur Verhinderung der Hautbräunung, insbesondere der durch UV-Strahlung hervorgerufenen Hautbräunung, sowie zur Aufhellung keratinischer Fasern, insbesondere der natürlichen menschlichen Haarfarbe.The present invention relates to cosmetic or dermatological compositions for the cosmetic and topical dermatological skin whitening or to the prevention of tanning of the skin, in particular the skin tanning caused by UV radiation, as well as for lightening keratinic fibers, in particular the natural human hair color.
Die Pigmentierung der Haut erfolgt durch Melanozyten, welche in der untersten Schicht der Epidermis neben den Basalzellen als je nach Hauttyp entweder vereinzelt oder gehäuft auftretende pigmentbildende Zellen vorzufinden sind. Melanozyten enthalten Melanosomen, in denen Melanin gebildet wird. Durch verschiedene chemische und/oder physikalische Einflüsse, insbesondere durch UV- Strahlung, wird verstärkt Melanin gebildet. Dieses wird über die Keratinozyten in die Corneozyten (Hornschicht) transportiert und führt zu einer bräunlichen bis braun-schwarzen Hautfarbe. Melanin wird als Endstufe eines oxidativen Prozesses gebildet, in welchem Tyrosin unter Mitwirkung der Enzyms Tyrosinase über mehrere Zwischenstufen zu den braun bis braunschwarzen Eumelaninen (DHICA- und DHI-Melanin) bzw. unter Beteiligung von schwefelhaltigen Verbindungen zum rötlichen Phäomelanin umgewandelt wird.The pigmentation of the skin is carried out by melanocytes, which are found in the lowest layer of the epidermis in addition to the basal cells as either isolated or frequently occurring pigment-forming cells depending on the skin type. Melanocytes contain melanosomes in which melanin is formed. Through various chemical and / or physical influences, in particular by UV radiation, melanin is increasingly formed. This is transported via the keratinocytes into the corneocytes (horny layer) and leads to a brownish to brown-black skin color. Melanin is formed as the final stage of an oxidative process in which tyrosine is converted by means of the enzyme tyrosinase via several intermediates to the brown to brown-black eumelanins (DHICA and DHI melanin) or with the involvement of sulfur-containing compounds to the reddish phaeomelanin.
Für die Haarfarbe sind - analog zur Pigmentierung der Haut - ebenfalls Melanin-produzierende Melanozyten verantwortlich. Die Menge und Zusammensetzung des Melanins in den Haaren bestimmt die natürliche Haarfarbe, die genetisch festgelegt ist.Like the skin pigmentation, melanin-producing melanocytes are responsible for the hair color. The amount and composition of melanin in hair determines the natural hair color that is genetically determined.
Die Melaninbildung - und damit Haut- und Haarfarbe - unterliegt äußeren Einflüssen und kann neben erwünschten Effekten („gesunde Bräune") auch zu unerwünschten Erscheinungen führen. So kann z.B. UV-Strahlung zu Sommersprossen führen. Fehlpigmentierungen können auch aufgrund genetischer Disposition, Wundheilung bzw. -vernarbung oder Hautalterung („Altersflecken") auftreten.Melanin formation - and thus skin and hair color - is subject to external influences and can cause unwanted effects in addition to the desired effects ("healthy tan"), eg UV radiation can lead to freckles. scarring or skin aging ("age spots") occur.
Da der Prozess der Desquamation (oberflächliche Loslösung von Zellen oder Zellgruppen aus ihrem epithelialen Verband) einen beständigen Verlust an Melanin beinhaltet, kann eine Aufhellung der Haut durch Inhibierung der Neusynthese von Melanin erreicht werden.Since the process of desquamation (superficial detachment of cells or cell groups from their epithelial dressing) involves a constant loss of melanin, lightening of the skin can be achieved by inhibiting the new synthesis of melanin.
Wirksame kosmetische Zubereitungen zur Hautaufhellung sind bekannt. Diese enthalten als Wirkstoff jedoch zumeist Hydrochinon oder Kojisäure (Inhibierung der Tyrosinase). Beide Substanzen sind mutagen und sollten daher nicht über längere Zeiträume verwendet werden.
Zur Aufhellung der Haarfarbe werden meist oxidative Verfahren angewandt, bekannt ist hier vor allem die Blondierung von Haaren mit Wasserstoffperoxid. Diese Verfahren können aber zu einer Schädigung der Haare führen.Effective cosmetic preparations for skin lightening are known. These contain as active ingredient, however, mostly hydroquinone or kojic acid (inhibition of tyrosinase). Both substances are mutagenic and should therefore not be used for prolonged periods. To lighten the hair color usually oxidative methods are used, is known here especially the bleaching of hair with hydrogen peroxide. However, these methods can lead to damage to the hair.
Es bestand daher nach wie vor die Aufgabe, haut- und/oder haaraufhellende Zubereitungen zur Verfügung zu stellen, die frei von den genannten Nachteilen sind.It was therefore still the task to provide skin and / or hair lightening preparations that are free of the disadvantages mentioned.
Es hat sich überraschenderweise gezeigt, dass die Kombination von 8-Hexadecen-1 ,16-dicarbon- säure mit Vitamin C oder Derivaten von Vitamin C (beispielsweise Ascorbylphosphat, Ascorbylglu- cosid, Ascorbyltetraisopalmitat) zu einer synergistischen Inhibition der Melaninsynthese führt. Bei grossflächiger Anwendung auf der Haut führt dies insbesondere bei Indern und Asiaten zu einer Aufhellung der Hautfarbe. Bei lokaler Anwendung auf Pigmentstörungen wie Altersflecken verlieren diese an Kontrast gegenüber dem angrenzenden Hautareal und sind daher weniger sichtbar.It has surprisingly been found that the combination of 8-hexadecene-1, 16-dicarboxylic acid with vitamin C or derivatives of vitamin C (for example ascorbyl phosphate, ascorbyl glucoside, ascorbyl tetraisopalmitate) leads to a synergistic inhibition of melanin synthesis. In large-scale application on the skin, this leads to a lightening of the skin color, especially in Indians and Asians. When applied locally to pigmentary disorders such as age spots, they lose contrast to the adjacent skin area and are therefore less visible.

Als weiteren wesentlichen Bestandteil enthalten die erfindungsgemäßen Zusammensetzungen Ascorbinsäure und/oder Ascorbinsäuredehvate.As a further essential constituent, the compositions according to the invention contain ascorbic acid and / or ascorbic acid derivatives.
Ascorbinsäure {(R)-5-[(S)-1 ,2-Dihydroxyethyl]-3,4-dihydroxy-5H-furan-2-on, auch Vitamin C genannt} ist das am längsten bekannte Vitamin. L-Ascorbinsäure ist ein Endiol und wirkt stark reduzierend. Mit Metallen bildet L-Ascorbinsäure als vinyloge Säure stabile Salze. Mit ihren alkoholischen Hydroxy-Gruppen bildet sie mit Fettsäuren Ester, z. B. L-Ascorbylpalmitat. Wichtigste Handelsformen sind neben L-Ascorbinsäure die wasserlöslichen Salze Natrium-L-ascorbat, Calcium-L- ascorbat und das fettlösliche L-Ascorbylpalmitat. Die Endiol-Gruppe an C2 und C3 geht leicht in die 2,3-Dioxo-Gruppe über. Dehydroascorbinsäure als primäres Oxidationsprodukt bildet mit Ascorbinsäure ein Redoxsystem. Der Lacton-Ring der Dehydroascorbinsäure kann hydrolysiert werden, wobei nicht Vitamin-wirksame Dioxogulonsäure entsteht. Eine Rückbildung zu Ascorbinsäure ist nicht mehr möglich. Die meisten Tier- und Pflanzenspezies sind zu einer eigenen Biosynthese von L-Ascorbinsäure befähigt, Mensch, Primaten und Meerschweinchen jedoch nicht. In einigen Lebensmitteln, z. B. Sauerkraut oder Kohlgemüse, kann L-Ascorbinsäure in Form des vitaminunwirksamen Ascorbigens an Glucosinolate gebunden vorliegen:
Ascorbic acid {(R) -5 - [(S) -1,2-dihydroxyethyl] -3,4-dihydroxy-5H-furan-2-one, also called vitamin C} is the longest known vitamin. L-ascorbic acid is an endiol and has a strong reducing effect. With metals, L-ascorbic acid forms stable salts as vinylogous acid. With its alcoholic hydroxy groups it forms esters with fatty acids, eg. B. L-ascorbyl palmitate. The most important commercial forms are, in addition to L-ascorbic acid, the water-soluble salts sodium L-ascorbate, calcium L-ascorbate and the fat-soluble L-ascorbyl palmitate. The endiol group at C2 and C3 readily converts to the 2,3-dioxo group. Dehydroascorbic acid as the primary oxidation product forms a redox system with ascorbic acid. The lactone ring of dehydroascorbic acid can be hydrolyzed to produce non-vitamin-active dioxogulonic acid. A regression to ascorbic acid is no longer possible. Most animal and plant species are capable of their own biosynthesis of L-ascorbic acid, humans, primates and guinea pigs not. In some foods, eg. As sauerkraut or cabbage, L-ascorbic acid in the form of the vitamin-unsubstituted Ascorbigens may be bound to glucosinolates:

Ascorbigen A Ascorbigen BAscorbigen A Ascorbigen B
Technisch wird L-Ascorbinsäure in einer Kombination einer mikrobiellen und mehrerer anschließender chemischer Reaktionen hergestellt. Man geht von D-Sorbit aus, der durch Fermentation mit dem Bakterium Acetobacter suboxydans zu dem Ketozucker L-Sorbose dehydriert wird. Sorbose wird anschließend durch chemische Oxidation in 2-Oxo-L-gulonsäure überführt, aus der in alkalischer Lösung das Natrium-Salz der Enol-Verbindung entsteht. Diese geht beim Ansäuern direkt in L-Ascorbinsäure über.Technically, L-ascorbic acid is produced in a combination of a microbial and several subsequent chemical reactions. It starts from D-sorbitol, which is dehydrated by fermentation with the bacterium Acetobacter suboxydans to the keto sugar L-sorbose. Sorbose is then converted by chemical oxidation into 2-oxo-L-gulonic acid, from which the sodium salt of the enol compound is formed in alkaline solution. This goes on acidification directly into L-ascorbic acid.

Als wasserunlöslich sind im Rahmen der Erfindung solche UV-Filter zu verstehen, die sich bei 20 0C zu nicht mehr als 1 Gew.-%, insbesondere zu nicht mehr als 0,1 Gew.-%, in Wasser lösen. Weiterhin sollten diese Verbindungen in üblichen kosmetischen ölkomponenten bei Raumtemperatur zu mindestens 0,1 , insbesondere zu mindestens 1 Gew.-% löslich sein).

Verbindungen, von denen sich der Strukturteil U ableiten kann, sind beispielsweise substituierte Benzophenone, p-Aminobenzoesäureester,The structural part U stands for a UV-absorbing group. This group can in principle be derived from the known UV filters which can be used in the cosmetics sector, in which a group, generally a hydrogen atom, of the UV filter is replaced by a cationic group Q, in particular having a quaternary amino function , Compounds from which the structural part U can be derived are, for example, substituted benzophenones, p-aminobenzoic acid esters,

UV-Filter mit einem Absorptionsmaximum im UVB-Bereich, insbesondere im Bereich von etwa 280 bis etwa 300 nm, sind besonders bevorzugt.The structural parts U can in principle be chosen such that the absorption maximum of the UV filters can be both in the UVA (315-400 nm) and in the UVB (280-315 nm) or in the UVC (<280 nm) range.

R4O-[GJp (E4-II)R 4 O- [GJ p (E4-II)
in der R4 für einen Alkyl- oder Alkenylrest mit 4 bis 22 Kohlenstoffatomen, G für einen Zuckerrest mit 5 oder 6 Kohlenstoffatomen und p für Zahlen von 1 bis 10 steht. Sie können nach den einschlägigen Verfahren der präparativen organischen Chemie erhalten werden. Die Alkyl- und Alkenyloligoglykoside können sich von Aldosen bzw. Ketosen mit 5 oder 6 Kohlenstoffatomen, vorzugsweise von Glucose, ableiten. Die bevorzugten Alkyl- und/oder Alkenyloligoglykoside sind somit Alkyl- und/oder Alkenyloligoglucoside. Die Indexzahl p in der allgemeinen Formel (E4-II) gibt den Oligomerisierungsgrad (DP), d. h. die Verteilung von Mono- und Oligoglykosiden an und steht für eine Zahl zwischen 1 und 10. Während p im einzelnen Molekül stets ganzzahlig sein muss und hier vor allem die Werte p = 1 bis 6 annehmen kann, ist der Wert p für ein bestimmtes Alkyloligoglykosid eine analytisch ermittelte rechnerische Größe, die meistens eine gebrochene Zahl darstellt. Vorzugsweise werden Alkyl- und/oder Alkenyloligoglykoside mit einem mittleren Oligomerisierungsgrad p von 1 ,1 bis 3,0 eingesetzt. Aus anwendungstechnischer Sicht sind solche Alkyl- und/oder Alkenyloligoglykoside bevorzugt, deren Oligomerisierungsgrad kleiner als 1 ,7 ist und insbesondere zwischen 1 ,2 und 1 ,4 liegt. Der Alkyl- bzw. Alkenylrest R4 kann sich von primären Alkoholen mit 4 bis 11 , vorzugsweise 8 bis
10 Kohlenstoffatomen ableiten. Typische Beispiele sind Butanol, Capronalkohol, Caprylalkohol, Caprinalkohol und Undecylalkohol sowie deren technische Mischungen, wie sie beispielsweise bei der Hydrierung von technischen Fettsäuremethylestern oder im Verlauf der Hydrierung von Aldehyden aus der Roelen'schen Oxosynthese erhalten werden.

Typische Beispiele sind Laurylalkohol, Myristylalkohol, Cetylalkohol, Palmoleylalkohol, Stearylalkohol, Isostearylalkohol, Oleylalkohol, Elaidylalkohol, Petroselinylalkohol, Arachylalkohol, Gadoleylalkohol, Behenylalkohol, Erucylalkohol, Brassidylalkohol sowie deren technische Gemische, die wie oben beschrieben erhalten werden können. Bevorzugt sind Alkyloligoglucoside auf Basis von gehärtetem C12/i4-Kokosalkohol mit einem DP von 1 bis 3. Zuckertenside vom Typ der Fettsäure-N-alkylpolyhydroxyalkylamide, ein nichtionisches Tensid der Formel (E4-III),in which R 4 is an alkyl or alkenyl radical having 4 to 22 carbon atoms, G is a sugar radical having 5 or 6 carbon atoms and p is a number from 1 to 10. They can be obtained by the relevant methods of preparative organic chemistry. The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (E4-II) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides and stands for a number between 1 and 10. While p in the individual molecule must always be integer and here before For all given values p = 1 to 6, the value p for a given alkyloligoglycoside is an analytically determined arithmetic quantity, which usually represents a fractional number. Preference is given to using alkyl and / or alkenyl oligoglycosides having an average degree of oligomerization p of from 1.1 to 3.0. From an application point of view, those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.4 are preferred. The alkyl or alkenyl radical R 4 can be from primary alcohols having 4 to 11, preferably 8 to Derive 10 carbon atoms. Typical examples are butanol, caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and technical mixtures thereof, as obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the hydrogenation of aldehydes from Roelen's oxo synthesis.

R5CO-NR6-[Z] (E4-III)R 5 CO-NR 6 - [Z] (E4-III)
in der R5CO für einen aliphatischen Acylrest mit 6 bis 22 Kohlenstoffatomen, R6 für Wasserstoff, einen Alkyl- oder Hydroxyalkylrest mit 1 bis 4 Kohlenstoffatomen und [Z] für einen linearen oder verzweigten Polyhydroxyalkylrest mit 3 bis 12 Kohlenstoffatomen und 3 bis 10 Hydroxylgruppen steht. Bei den Fettsäure-N-alkylpolyhydroxyalkylamiden handelt es sich um bekannte Stoffe, die üblicherweise durch reduktive Aminierung eines reduzierenden Zuckers mit Ammoniak, einem Alkylamin oder einem Alkanolamin und nachfolgende Acylierung mit einer Fettsäure, einem Fettsäurealkylester oder einem Fettsäurechlorid erhalten werden. Vorzugsweise leiten sich die Fettsäure-N-alkylpolyhydroxyalkylamide von reduzierenden Zuckern mit 5 oder 6 Kohlenstoffatomen, insbesondere von der Glucose ab. Die bevorzugten Fettsäure-N- alkylpolyhydroxyalkylamide stellen daher Fettsäure-N-alkylglucamide dar, wie sie durch die Formel (E4-IV) wiedergegeben werden:R 5 is CO for an aliphatic acyl radical having 6 to 22 carbon atoms, R 6 is hydrogen, an alkyl or hydroxyalkyl radical having 1 to 4 carbon atoms and [Z] is a linear or branched polyhydroxyalkyl radical having 3 to 12 carbon atoms and 3 to 10 hydroxyl groups stands. The fatty acid N-alkyl polyhydroxyalkylamides are known substances which are usually obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride. Preferably, the fatty acid N-alkylpolyhydroxyalkylamides are derived from reducing sugars having 5 or 6 carbon atoms, especially glucose. The preferred fatty acid N-alkylpolyhydroxyalkylamides are therefore fatty acid N-alkylglucamides as represented by the formula (E4-IV):
R7CO-NR8-CH2-(CHOH)4-CH2OH (E4-IV)R 7 CO-NR 8 -CH 2 - (CHOH) 4 -CH 2 OH (E4-IV)

(E4-IV), die durch reduktive Aminierung von Glucose mit Methylamin und anschließende Acy- lierung mit Laurinsäure oder C12/14-Kokosfettsäure bzw. einem entsprechenden Derivat erhalten werden. Weiterhin können sich die Polyhydroxyalkylamide auch von Maltose und Palati- nose ableiten.The fatty acid N-alkylpolyhydroxyalkylamides used are preferably glucamides of the formula (E4-IV) in which R 8 is hydrogen or an alkyl group and R 7 CO is the acyl radical of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitic acid, Stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid, behenic acid or erucic acid or their technical mixtures. Particular preference is given to fatty acid N-alkylglucamides of the formula (E4-IV), which are obtained by reductive amination of glucose with methylamine and subsequent acylation with lauric acid or C12 / 14 coconut fatty acid or a corresponding derivative. Furthermore, the polyhydroxyalkylamides can also be derived from maltose and palatinose.
Als bevorzugte nichtionische Tenside haben sich die Alkylenoxid-Anlagerungsprodukte an gesättigte lineare Fettalkohole und Fettsäuren mit jeweils 2 bis 30 Mol Ethylenoxid pro Mol Fettalkohol bzw. Fettsäure erwiesen. Zubereitungen mit hervorragenden Eigenschaften werden ebenfalls erhalten, wenn sie als nichtionische Tenside Fettsäureester von ethoxyliertem Glycerin enthalten.The preferred nonionic surfactants are the alkylene oxide addition products of saturated linear fatty alcohols and fatty acids having in each case 2 to 30 moles of ethylene oxide per mole of fatty alcohol or fatty acid. Preparations having excellent properties are also obtained if they contain fatty acid esters of ethoxylated glycerol as nonionic surfactants.
Diese Verbindungen sind durch die folgenden Parameter gekennzeichnet. Der Alkylrest R enthält 6 bis 22 Kohlenstoffatome und kann sowohl linear als auch verzweigt sein. Bevorzugt sind primäre lineare und in 2-Stellung methylverzweigte aliphatische Reste. Solche Alkylreste sind beispielsweise 1-Octyl, 1-Decyl, 1-Lauryl, 1-Myristyl, 1-Cetyl und 1-Stearyl. Besonders bevorzugt sind 1- Octyl, 1-Decyl, 1-Lauryl, 1-Myristyl. Bei Verwendung sogenannter "Oxo-Alkohole" als Ausgangsstoffe überwiegen Verbindungen mit einer ungeraden Anzahl von Kohlenstoffatomen in der Alkyl- kette.These connections are identified by the following parameters. The alkyl radical R contains 6 to 22 carbon atoms and may be both linear and branched. Preference is given to primary linear and methyl-branched in the 2-position aliphatic radicals. Such alkyl radicals are, for example, 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. Particularly preferred are 1-octyl, 1-decyl, 1-lauryl, 1-myristyl. When so-called "oxo-alcohols" are used as starting materials, compounds with an odd number of carbon atoms in the alkyl chain predominate.
Weiterhin sind ganz besonders bevorzugte nichtionische Tenside die Zuckertenside. Diese können in den erfindungsgemäß verwendeten Mitteln bevorzugt in Mengen von 0,1 - 20 Gew.-%, bezogen auf das gesamte Mittel, enthalten sein. Mengen von 0,5 - 15 Gew.-% sind bevorzugt, und ganz besonders bevorzugt sind Mengen von 0,5 - 7,5 Gew.%.Furthermore, very particularly preferred nonionic surfactants are the sugar surfactants. These may preferably be present in the agents used according to the invention in amounts of from 0.1 to 20% by weight, based on the total agent. Amounts of 0.5-15% by weight are preferred, and most preferred are amounts of 0.5-7.5% by weight.
Bei den als Tensid eingesetzten Verbindungen mit Alkylgruppen kann es sich jeweils um einheitliche Substanzen handeln. Es ist jedoch in der Regel bevorzugt, bei der Herstellung dieser Stoffe von nativen pflanzlichen oder tierischen Rohstoffen auszugehen, so dass man Substanzgemische mit unterschiedlichen, vom jeweiligen Rohstoff abhängigen Alkylkettenlängen erhält.The compounds used as surfactant with alkyl groups may each be uniform substances. However, it is generally preferred to use native vegetable or animal raw materials in the production of these substances, so that substance mixtures having different alkyl chain lengths depending on the respective raw material are obtained.
Bei den Tensiden, die Anlagerungsprodukte von Ethylen- und/oder Propylenoxid an Fettalkohole oder Derivate dieser Anlagerungsprodukte darstellen, können sowohl Produkte mit einer "normalen" Homologenverteilung als auch solche mit einer eingeengten Homologenverteilung verwendet werden. Unter "normaler" Homologenverteilung werden dabei Mischungen von Homologen verstanden, die man bei der Umsetzung von Fettalkohol und Alkylenoxid unter Verwendung von Alkalimetallen, Alkalimetallhydroxiden oder Alkalimetallalkoholaten als Katalysatoren erhält. Eingeengte Homologenverteilungen werden dagegen erhalten, wenn beispielsweise Hydrotalcite, Erdalkalimetallsalze von Ethercarbonsäuren, Erdalkalimetalloxide, -hydroxide oder -alkoholate als Katalysatoren verwendet werden. Die Verwendung von Produkten mit eingeengter Homologenverteilung kann bevorzugt sein.
Erfindungsgemäß einsetzbar sind kationische Tenside vom Typ der quarternären Ammoniumverbindungen, der Esterquats und der Amidoamine. Bevorzugte quaternäre Ammoniumverbindungen sind Ammoniumhalogenide, insbesondere Chloride und Bromide, wie Alkyltrimethylammonium- chloride, Dialkyldimethylammoniumchloride und Trialkylmethylammoniumchloride, z. B.

Die langen Alkylketten der oben genannten Tenside weisen bevorzugt 10 bis 18 Kohlenstoffatome auf.In the case of the surfactants which are adducts of ethylene oxide and / or propylene oxide with fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution and those with a narrow homolog distribution can be used. By "normal" homolog distribution are meant mixtures of homologs obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts.

Bevorzugt werden jedoch Mischungen verschiedener Riechstoffe verwendet, die gemeinsam eine ansprechende Duftnote erzeugen.The compositions of the invention may contain perfumes, perfume oils or perfume oil ingredients. Perfume oils or fragrances can according to the invention individual fragrance compounds, such as the synthetic products of the ester, ether, aldehyde, ketone, alcohol and Be hydrocarbons. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate (DMBCA), phenylethyl acetate, benzyl acetate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate, benzylsalicylate, cyclohexylsalicylate, floramate, melusate and jasmecyclate.

Solche Parfümöle können auch natürliche Riechstoffgemische enthalten, wie sie aus pflanzlichen Quellen zugänglich sind, z.B. Pine-, Citrus-, Jasmin-, Patchouly-, Rosen- oder Ylang-Ylang-Öl. Ebenfalls geeignet sind Muskateller-Salbeiöl, Kamillenöl, Nelkenöl, Melissenöl, Minzöl, Zimtblätter- öl, Lindenblütenöl, Wacholderbeeröl, Vetiveröl, Olibanumöl, Galbanumöl und Labdanumöl sowie Orangenblütenöl, Neroliol, Orangenschalenöl und Sandelholzöl.Such perfume oils may also contain natural fragrance mixtures such as are available from vegetable sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil.

Um wahrnehmbar zu sein, muss ein Riechstoff flüchtig sein, wobei neben der Natur der funktionellen Gruppen und der Struktur der chemischen Verbindung auch die Molmasse eine wichtige Rolle spielt. So besitzen die meisten Riechstoffe Molmassen bis etwa 200 Dalton, während Molmassen von 300 Dalton und darüber eher eine Ausnahme darstellen. Aufgrund der unterschiedlichen Flüchtigkeit von Riechstoffen verändert sich der Geruch eines aus mehreren Riechstoffen zusammengesetzten Parfüms bzw. Duftstoffs während des Verdampfens, wobei man die Geruchseindrücke in „Kopfnote" (top note), „Herz- bzw. Mittelnote" (middle note bzw. body) sowie „Basisnote" (end note bzw. dry out) unterteilt. Da die Geruchswahrnehmung zu einem großen Teil auch auf der Geruchsintensität beruht, besteht die Kopfnote eines Parfüms bzw. Duftstoffs nicht allein aus leichtflüchtigen Verbindungen, während die Basisnote zum größten Teil aus weniger flüchtigen, d.h. haftfesten Riechstoffen besteht. Bei der Komposition von Parfüms können leichter flüchtige Riechstoffe beispielsweise an bestimmte Fixative gebunden werden, wodurch ihr zu schnelles Verdampfen verhindert wird. Bei der nachfolgenden Einteilung der Riechstoffe in „leichter flüchtige" bzw. „haftfeste" Riechstoffe ist also über den Geruchseindruck und darüber, ob der entsprechende Riechstoff als Kopf- oder Herznote wahrgenommen wird, nichts ausgesagt.In order to be perceptible, a fragrance must be volatile, whereby besides the nature of the functional groups and the structure of the chemical compound, the molecular weight also plays an important role. For example, most odorants have molecular weights up to about 200 daltons, while molecular weights of 300 daltons and above are more of an exception. Due to the different volatility of fragrances, the smell of a perfume or fragrance composed of several fragrances changes during evaporation, whereby the odor impressions in "top note", "middle note or body" As the smell perception is based to a large extent on the odor intensity, the top note of a perfume or fragrance consists not only of volatile compounds, while the base note for the most part from less volatile In the composition of perfumes, for example, volatile fragrances can be bound to certain fixatives, which prevents them from evaporating too quickly the smell impression and on whether the corre sponding is perceived as the head or middle note, nothing said.
