Abstract

Self-foaming and/or foam-like cosmetic or dermatological preparations which comprise

Description

[0001] The present invention relates to self-foaming and/or foam-like cosmetic and derma-tological preparations, in particular to skincare cosmetic and dermatological preparations.

[0002] Foams or foam-like preparations are a type of disperse system.

[0003] By far the most important and best known disperse systems are emulsions. Emulsions are two- or multi-phase systems of two or more liquids which are insoluble or only slightly soluble in one another. The liquids (pure or as solutions) are present in an emulsion in a more or less fine distribution, which generally has only limited stability.

[0004] Foams are structures of gas-filled, spherical or polyhedral cells which are delimited by liquid, semiliquid, high-viscosity or solid cell ribs. The cell ribs, connected via points of intersection form a continuous framework. The foam lamellae stretch between the cell ribs (closed-cell foam). If the foam lamellae are disturbed or if they flow back into the cell rib at the end of foam formation, an open-cell foam is obtained. Foams are also thermo-dynamically unstable since a reduction in the surface area leads to the production of surface energy. The stability and thus the existence of a foam is thus dependent on to what extent it is possible to prevent its self-destruction.

[0005] Cosmetic foams are usually dispersed systems of liquids and gases, where the liquid represents the dispersant and the gas represents the dispersed substance. Foams of low-viscosity liquids are temporarily stabilized by surface-active substances (surfactants, foam stabilizers). Because of their large internal surface area, such surfactant foams have a high adsorption capacity, which is utilized, for example, in cleaning and washing operations. Accordingly, cosmetic foams are used, in particular, in the fields of cleansing, for example as shaving foam, and of haircare.

[0006] To generate foam, gas is bubbled into suitable liquids, or foam formation is achieved by vigorously beating, shaking, spraying or stirring the liquid in the gas atmosphere in question, provided that the liquids comprise suitable surfactants or other interface-active substances (“foam formers”), which, apart from i nterfacial activity, also have a certain film-forming ability.

[0007] Cosmetic foams have the advantage over other cosmetic preparations of permitting a fine distribution of active ingredients on the skin. However, cosmetic foams can generally only be achieved using particular surfactants, which, moreover, are often not well tolerated by the skin.

[0008] A further disadvantage of the prior art is that such foams have only low stability, for which reason they usually collapse within approximately 24 hours. A requirement of cosmetic preparations, however, is that they have stability for years, as far as possible. This problem is generally taken into account by the fact that the consumer produces the actual foam himself just before use using a suitable spray system for which purpose, for example, it is possible to use spray cans in which a liquefied pressurized gas serves as propellant gas. Upon opening the pressure valve, the propellant liquid mixture escapes through a fine nozzle, and the propellant evaporates, leaving behind a foam.

[0009] After-foaming cosmetic preparations are also known per se. They are firstly applied to the skin from an aerosol container in flowable form and, after a short delay, develop the actual foam only once they are on the skin under the effect of the after-foaming agent present, for example a shaving foam. After-foaming preparations are often in specific formulation forms, such as, for example, after-foaming shaving gels or the like.

[0010] However, the prior art does not include any sort of cosmetic or dermatological preparations which could be foamed as early as during the preparation and nevertheless have a sufficiently high stability in order to be packaged in the usual manner, stored and put onto the market.

[0011] An object of the present invention was therefore to enrich the prior art and to provide cosmetic or dermatological self-foaming and/or foam-like preparations which do not have the disadvantages of the prior art.

[0012] German laid-open specification DE 197 54 659 discloses that carbon dioxide is a suitable active ingredient for stabilizing or increasing the epidermal ceramide synthesis rate, which may serve to enhance the permeability barrier, reduce the transepidermal water loss and increase the relative skin moisture. To treat the skin, the CO2 is, for example, dissolved in water, which is then used to rinse the skin. However, the prior art hitherto does not include any sort of cosmetic or dermatological bases in which a gaseous active ingredient could be incorporated in an adequate, i.e. effective, concentration.

[0013] It was thus a further object of the present invention to find cosmetic or dermatological bases into which effective amounts of gaseous active ingredients can be incorporated.

[0014] It was surprising and could not have been foreseen by the person skilled in the art that self-foaming and/or foam-like cosmetic or dermatological preparations which comprise

[0015] I. an emulsifier system which consists of

[0016] A. at least one emulsifier A chosen from the group of wholly neutralized, partially neutralized or unneutralized branched and/or unbranched, saturated and/or unsaturated fatty acids having a chain length of from 10 to 40 carbon atoms,

[0017] B. at least one emulsifier B chosen from the group of polyethoxylated fatty acid esters having a chain length of from 10 to 40 carbon atoms and a degree of ethoxylation of from 5 to 100 and

[0018] C. at least one coemulsifier C chosen from the group of saturated and/or unsaturated, branched and/or unbranched fatty alcohols having a chain length of from 10 to 40 carbon atoms,

[0019] II. up to 30% by weight—based on the total weight of the preparation—of a lipid phase,

[0020] III. 1 to 90% by volume, based on the total volume of the preparation, of at least one gas chosen from the group consisting of air, oxygen, nitrogen, helium, argon, nitrous oxide (N2O) and carbon dioxide (CO2)

[0021] IV. one or more substances chosen from the group of organic hydrocolloids

[0022] V. 0.01 -10% by weight of one or more particulate hydrophobic and/or hydrophobicized and/or oil-absorbing solid-body substances, overcome the disadvantages of the prior art.

[0023] According to the prior art to date, foam-like cosmetic emulsions which are characterized by a high introduction of air cannot be formulated or prepared industrially without propellent gas. This is true in particular for systems which are based on classic emulsifiers and gelling agents and develop a foam with an extraordinarily high stability as a result of shearing (stirring, homogenization). As a result of the invention, the introduction of the gases is aided, and a stabilizing and significantly after-foaming effect is achieved over a prolonged storage period, even at relatively high temperatures (e.g. 40° C.), without comprising after-foaming agents customary according to the prior art, such as, for example, by propellent gases.

[0024] The introduction of the gases is extraordinarily increased. For example, foam boosting with up to 100% increased gas volume can be achieved without comprising foaming agents customary according to the prior art, such as surfactants.

[0025] As a result of this, it is possible for the first time, compared with the prior art to date, to stably generate formulations with an excellent, novel type of cosmetic activity and with an extraordinarily high gas volume (air and/or other gases, such as oxygen, carbon dioxide, nitrogen, helium, argon etc.) over a long storage period at high temperatures. At the same time, they are characterized by above-average good skin care and very good sensory properties.

[0026] For the purposes of the present invention, “self-foaming” or “foam-like” are understood as meaning that the gas bubbles are present in (any) distributed form in one (or more) liquid phase(s) where the preparations do not necessarily have to have the appearance of a foam in macroscopic terms. Self-foaming and/or foam-like cosmetic or dermatological preparations according to the invention can, for example, be macroscopically visibly dispersed systems of gases dispersed in liquids. The foam character can, however, for example, be visible also only under a (light) microscope. Moreover, self-foaming and/or foam-like preparations according to the invention are, particularly when the gas bubbles are too small to be recognized under a light microscope, also recognizable from the sharp increase in volume of the system.

[0027] The preparations according to the invention are entirely satisfactory preparations in every respect. It was particularly surprising that the foam-like preparations according to the invention are extraordinarily stable, even in cases of an unusually high gas volume. Accordingly, they are particularly suitable for use as bases for preparation forms having diverse use purposes. The preparations according to the invention have very good sensory properties, such as, for example, distributability on the skin or the ability to be absorbed into the skin, and are, moreover, characterized by above-average skincare.

[0028] The invention further provides for

[0029] the use of self-foaming and/or foam-like. cosmetic or dermatological preparations which comprise

[0030] I. an emulsifier system which consists of

[0031] A. at least one emulsifier A chosen from the group of wholly neutralized, partially neutralized or unneutralized branched and/or unbranched, saturated and/or unsaturated fatty acids having a chain length of from 10 to 40 carbon atoms,

[0032] B. at least one emulsifier B chosen from the group of polyethoxylated fatty acid esters having a chain length of from 10 to 40 carbon atoms and a degree of ethoxylation of from 5 to 100 and

[0033] C. at least one coemulsifier C chosen from the group of saturated and/or unsaturated, branched and/or unbranched fatty alcohols having a chain length of from 10 to 40 carbon atoms,

[0034] II. up to 30% by weight—based on the total weight of the preparation—of a lipid phase,

[0035] IV. one or more substances chosen from the group of organic hydrocolloids

[0036] VI. 0.01-10% by weight of one or more particulate hydrophobic and/or hydro-phobicized and/or oil-absorbing solid-body substances,

[0037] as cosmetic or dermatological bases for gaseous active ingredients.

[0038] The emulsifier(s) A is/are preferably chosen from the group of fatty acids which have been wholly or partially neutralized with customary alkalis (such as, for example, sodium hydroxide and/or potassium hydroxide, sodium carbonate and/or potassium carbonate, and mono- and/or triethanolamine). Stearic acid and stearates, isostearic acid and isostearates, palmitic acid and palmitates, and myristic acid and myristates, for example, are particularly advantageous.

[0039] The emulsifier(s) B is/are preferably chosen from the following group: PEG-9 stearate, PEG-8 distearate, PEG-20 stearate, PEG-8 stearate, PEG-8 oleate, PEG-25 glyceryl trioleate, PEG-40 sorbitan lanolate, PEG-15 glyceryl ricinoleate, PEG-20 glyceryl stearate, PEG-20 glyceryl isostearate, PEG-20 glyceryl oleate, PEG-20 stearate, PEG-20 methylglucose sesquistearate, PEG-30 glyceryl isostearate, PEG-20 glyceryl laurate, PEG-30 stearate, PEG-30 glyceryl stearate, PEG-40 stearate, PEG-30 glyceryl laurate, PEG-50 stearate, PEG-100 stearate, PEG-150 laurate. Particularly advantageous are, for example, polylethoxylated stearic esters.

Particular preference is given to cetyl alcohol and cetylstearyl alcohol.

[0041] It is advantageous according to the invention to choose the weight ratios of emulsifier A to emulsifier B to coemulsifier C (A:B:C) as a:b:c, where a, b and c, independently of one another, may be rational numbers from 1 to 5, preferably from 1 to 3. Particular preference is given to a weight ratio of approximately 1:1:1.

[0042] It is advantageous for the purposes of the present invention to choose the total amount of emulsifiers A and B and of coemulsifier C from the range from 2 to 20% by weight, advantageously from 5 to 15% by weight, in particular from 8 to 13% by weight, in each case based on the total weight of the formulation.

[0043] For the purposes of the present invention, it is particularly preferred if the gas phase of the preparations comprises carbon dioxide or consists entirely of carbon dioxide. It is particularly advantageous if carbon dioxide is a or the active ingredient in the preparations according to the invention.

[0044] Compositions according to the invention develop, even during their preparation—for example during stirring or upon homogenization—into fine-bubble foams. According to the invention, fine-bubble, rich foams of excellent cosmetic elegance are obtainable. Furthermore, preparations which are particularly well tolerated by the skin are obtainable according to the invention, where valuable ingredients can be distributed on the skin in a particularly good manner.

[0045] It may be advantageous, although it is not necessary, for the formulations according to the present invention to comprise further emulsifiers. Preference is given to using those emulsifiers which are suitable for the preparation of W/O emulsions, it being possible for these to be present either individually or else in any combinations with one another.

[0056] “Hydrocolloid” is the technological abbreviation for the more correct name “hydrophilic colloid”. Hydrocolloids are macromolecules which have a largely linear structure and have intermolecular forces of interaction which permit secondary and primary valence bonds between the individual molecules and thus the formation of a recticular structure. Some are water-soluble natural or synthetic polymers which, in aqueous systems, form gels or viscous solutions. They increase the viscosity of the water by either binding water molecules (hydration) or else by absorbing and encapsulating the water into their interwoven macromolecules, at the same time as restricting the mobility of the water. Such water-soluble polymers represent a large group of chemically very different natural and synthetic polymers whose common feature is their solubility in water or aqueous media. A prerequisite for this is that these polymers have a number of hydrophilic groups sufficient for solubility in water and are not too greatly crosslinked. The hydrophilic groups may be nonionic, anionic or cationic in nature, for example as follows: 1

[0057] The group of the cosmetically and dermatologically relevant hydrocolloids can be divided as follows into:

[0058] organic, natural compounds, such as, for example, agar agar, carrageen, tragacanth, gum arabic, alginates, pectins, polyoses, guar flour, carob bean flour, starch, dextrins, getalins, caseine,

[0059] organic, modified natural substances, such as, for example, carboxymethylcellulose and other cellulose ethers, hydroxyethylcellulose and hydroxypropylcellulose and microcrystalline cellulose,

[0060] organic, completely synthetic compounds, such as, for example, polyacrylic and polymethacrylic compounds, vinyl polymers, polycarboxylic acids, polyethers, polyimines, polyamides, polyurethanes

[0061] inorganic compounds, such as, for example, polysilicic acids, clay minerals, such as montmorillonites, zeolites, silicas.

[0062] Microcrystalline cellulose is an advantageous hydrocolloid for the purposes of the present invention. It is obtainable, for example, from the “FMC Corporation Food and Pharma-ceutical Products” under the trade name Avicel®. A particularly advantageous product for the purposes of the present invnetion is the Avicel® grade RC-591, which is modified microcrystalline cellulose which is composed of 89% of microcrystalline cellulose and 11% of sodium carboxymethylcellulose. Further commercial products of this class of raw material are Avicel® RC/CL, Avicel® CE-15, Avicel® 500.

[0063] Further hydrocolloids which are advantageous according to the invention are, for example, methylcelluloses, which is the term used for the methyl ethers of cellulose. The are characterized by the following structural formula 2

[0064] in which R may be a hydrogen or a methyl group.

[0065] Particularly advantageous for the purposes of the present invention are the cellulose mixed ethers, which are generally likewise referred to as methylcelluloses, which contain, in addition to a predominating content of methyl groups, additionally 2-hydroxyethyl groups, 2-hydroxypropyl groups or 2-hydroxybutyl groups. Particular preference is given to (hydroxypropyl)methylcelluloses, for example those available under the trade name Methocel® E4M from Dow Chemical Comp.

[0066] Also advantageous according to the invention is sodium carboxymethylcellulose, the sodium salt of the glycolic ether of cellulose, for which R in structural formula I may be a hydrogen and/or CH2-COONa. Particular preference is given to the sodium carboxy-methylcellulose available under the trade name Natrosol Plus 330 CS from Aqualon and also referred to as cellulose gum.

[0067] Also preferred for the purposes of the present invention is xanthan (CAS No. 11138-66-2), also called xanthan gum, which is an anionic heteropolysaccharide which is usually formed by fermentation from corn sugar and is isolated as the potassium salt. It is produced by Xanthomonas campestris and some other species under aerobic conditions and has a molecular weight of from 2×106 to 24×106. Xanthan is formed from a chain having β-1,4-bonded glucose (cellulose) with side chains. The structure of the subgroups consists of glucose, mannose, glucuronic acid, acetate and pyruvate. Xanthan is the name given to the first microbial anionic heteropolysaccharide. It is produced by Xanthomonas campestris and some other species under aerobic conditions and has a molecular weight of from 2-15 106. Xanthan is formed from a chain having β-1,4-bonded glucose (cellulose) with side chains. The structure of the subgroups consists of glucose, mannose, glucuronic acid, acetate and pyruvate. The number of pyruvate units determines the viscosity of the xanthan. Xanthan is produced in two-day batch cultures with a yield of 70-90%, based on carbohydrate used. In this connection, yields of 25-30 g/l are achieved. After the culture has been destroyed, work-up takes place by precipitation with, for example, 2-propanol. Xanthan is then dried and ground.

[0068] An advantageous gel former for the purposes of the present invention is also carrageen, a gel-forming extract with a similar structure to agar, from North Atlantic red algae, which belong to the Florideae (Chondrus crispus and Gigartina stellata).

[0069] The term carrageen is frequently used for the dried algae product and carrageenan for the extract thereof. The carrageen precipitated from the hot-water extract of the algae is a colorless to sand-colored powder with a molecular weight range from 100 000-800 000 and a sulfate content of about 25%. Carrageen, which is very readily soluble in warm water, forms a thixotropic gel upon cooling, even if the water content is 95-98%. The rigidity of the gel is effected by the double helix structure of carrageen. In the case of carrageenan, three main constituents are differentiated: the gel-forming κ fraction consists of D-galactose 4-sulfate and 3,6-anhydro-α-D-galactose, which has alternate glycoside bonds in the 1,3- and 1,4-position (by contrast, agar contains 3,6-anhydro-α-L-galactose). The nongelling λ fraction is composed of 1,3-glycosidically linked D-galactose 2-sulfate and 1,4-bonded D-galactose-2,6-disulfate radicals, and is readily soluble in cold water. ι-Carrageenan, composed of D-galactose 4-sulfate in 1,3 bond and 3,6-anhydro-α-D-galactose 2-sulfate in 1,4 bond, is both water-soluble and also gel-forming. Further carrageen grades are likewise referred to using Greek letters: α, β, γ, μ, ν, ξ, π, ω, χ. The type of cations present (K+, NH4+, Na+, Mg2+, Ca2+) also influences the solubility of the carrageens.

[0070] The use of chitosan in cosmetic preparations is known per se. Chitosan represents a partially deacylated chitin. This biopolymer has, inter alia, film-forming properties and is characterized by a silky feel on the skin. A disadvantage, however, is its severe stickiness on the skin which occurs in particular—temporarily—during application. In individual cases, corresponding preparations may not then be marketable since they are unacceptable to and/or viewed negatively by the consumer. As is known, chitosan is used, for example, in hair care. It is suitable, to a better degree than the chitin on which it is based, as a thickener or stabilizer and improves the adhesion and water resistance of polymeric films. A representative of a large number of literature references for the prior art is: H. P. Fiedler, “Lexikon der Hilfsstoffe für Pharmazie, Kosmetik und angrenzende Gebiete” [Lexikon of Auxiliaries for Pharmacy, Cosmetics and Related Fields], third edition 1989, Editio Cantor, Aulendorf, p. 293, key word “chitosan”.

[0071] Chitosan is characterized by the following structural formula: 3

[0072] where n assumes values of up to 10 000, and X is either the acetyl radical or hydrogen. Chitosan forms by deacetylation and partial depolymerization (hydrolysis) of chitin, which is characterized by the structural formula 4

[0073] Chitin is an essential constituent of the ectoskeleton [‘oχιτων=Greek: integument] of arthropods (e.g. insects, crabs, spiders) and is also found in supporting tissues of other organisms (e.g. molluscs, algae, fungi).

[0074] In the region of about pH <6, chitosan is positively charged and in that range is also soluble in aqueous systems. It is incompatible with anionic raw materials. For this reason, to prepare chitosan-containing oil-in-water emulsions, the use of nonionic emulsifiers is appropriate. These are known per se, for example from EP-A 776 657.

[0075] Preference is given according to the invention to chitosans with a degree of deacetylation of >25%, in particular >55 to 99% [determined by means 1H-NMR]).

[0076] It is advantageous to choose chitosans with molecular weights between 10 000 and 1 000 000, in particular those with molecular weights between 100 000 and 1 000 000 [determined by means of gel permeation chromatography].

[0077] Polyacrylates are gelling agents likewise to be used advantageously for the purposes of the present invention. Polyacrylates advantageous according to the invention are acrylate-alkyl acrylate copolymers, in particular those chosen from the group of so-called carbomers or carbopols (Carbopol® is actually a registered trademark of B. F. Goodrich Company). In particular, the acrylate-alkyl acrylate copolymers advantageous according to the invention are characterized by the following structure: 5

[0078] where R′ is a long-chain alkyl radical, and x and y represent numbers which symbolize the respective stoichiometric proportion of each of the comonomers.

[0079] According to the invention, particular preference is given to acrylate copolymers and/or acrylate-alkyl acrylate copolymers which are available under the trade name Carbopol® 1382, Carbopol® 981 and Carbopol® 5984 from B. F. Goodrich Company, preferably polyacrylates from the group of Carbopol grades 980, 981, 1382, 2984, 5984 and particularly preferably Carbomer 2001.

[0080] Also advantageous are copolymers of C10-30-alkyl acrylates and one or more monomers of acrylic acid, of methacrylic acid or esters thereof which are crosslinked with an allyl ether of sucrose or an allyl ether of pentaerythritol.

[0081] Compounds which carry the INCI name “Acrylates/C10-30Alkyl Acrylate Crosspolymer” are advantageous. Particularly advantageous are those polymers available under the trade names Pemulen TR1 and Pemulen TR2 from B. F. Goodrich Company.

[0082] Compounds which carry the INCI name Ammonium Acryloyldimethyltaurates/Vinyl-pyrrolidone Copolymers are advantageous.

[0083] According to the invention, the ammonium acryloyldimethyltaurates/vinylpyrrolidone copolymers have the empirical formula [C7H16N2SO4]n[C6H9NO]m, which corresponds to the following statistical structure 6

[0084] Preferred species for the purposes of the present invention are listed in the Chemical Abstracts under the registry numbers 58374-69-9, 13162-05-5 and 88-12-0 and are available under the trade name Aristoflex® AVC from Clariant GmbH.

[0085] Also advantageous are copolymers/crosspolymers comprising acryloyl dimethyl taurate, such as, for example, Simugel ® EG or Simugel ® EG from Seppic S.A.

[0086] Further hydrocolloids which are to be used advantageously according to the invention are also

[0087] 1. anionic polyurethanes which are soluble or dispersible in water and which are advantageously obtainable from

[0088] i) at least one compound which contains two or more active hydrogen atoms per molecule,

[0089] ii) at least one diol containing acid or salt groups and

[0090] iii) at least one diisocyanate.

[0091] Component i) is, in particular, a diol, aminoalcohol, diamine, polyesterol, polyetherol with a number-average molecular weight of in each case up to 3000, or mixtures thereof, where up to 3 mol % of said compounds may be replaced by triols or triamines. Preference is given to diols and polyesterdiols. In particular, component (a) comprises at least 50% by weight, based on the total weight of component (a), of a polyesterdiol. Suitable p olyesterdiols a re a 11 t hose w hich a re c ustomarily u sed f or the preparation of polyurethanes, in particular reaction products of phthalic acid and diethylene glycol, isophthalic acid and 1,4-butanediol, isophthalic acid/adipic acid and 1,6-hexanediol, and adipic acid and ethylene glycol or 5-NaSO3-isophthalic acid, phthalic acid, adipic acid and 1,6-hexanediol.

[0092] Examples of diols which can be used are ethylene glycol, propylene glycol, butylene glycol, neopentyl glycol, polyetherols, such as polyethylene glycols with molecular weights up to 3000, block copolymers of ethylene oxide and propylene oxide with number-average molecular weights of up to 3000 or block copolymers of ethylene oxide, propylene oxide and butylene oxide which contain the copolymerized alkylene oxide units in random distribution or in the form of blocks. Preference is given to ethylene glycol, neopentyl glycol, di-, tri-, tetra-, penta- or hexaethylene glycol. Other diols which can be used are poly(α-hydroxycarboxylic acid)diols.

[0093] Suitable amino alcohols are, for example, 2-aminoethanol, 2-(N-methylamino)ethanol, 3-aminopropanol or 4-aminobutanol.

[0094] Examples of suitable diamines are ethylenediamine, propylenediamine, 1,4-diamino-butane and 1,6-diaminohexane, and a,co-diamines which can be prepared by amination of polyalkylene oxides with ammonia.

[0095] Component ii) is, in particular, dimethylolpropanoic acid or compounds of the formulae 7

[0096] where RR is in each case a C2-C18-alkylene group and Me is Na or K.

[0097] Component iii) is, in particular, hexamethylene diisocyanate, isophorone diisocyanate, methyidiphenyl isocyanate (MDI) and/or tolylene diisocyanate.

[0098] The polyurethanes are obtainable by reacting the compounds of groups i) and ii) under an inert-gas atmosphere in an inert solvent at temperatures of from 70 to 130° C. with the compounds of group iii). This reaction can optionally be carried out in the presence of chain extenders in order to prepare polyurethanes with relatively high molecular weights. As is customary in the preparation of polyurethanes, the components [(i)+(ii)]:iii) are advantageously used in the molar ratio from 0.8 to 1.1:1. The acid number of the polyurethanes is determined by the composition and the concentration of the compounds of component (ii) in the mixture of components (i)+(ii).

[0099] The polyurethanes have K values according to H. Fikentscher (determined in 0.1% strength by weight solutions in N-methylpyrrolidone at 25° C. and pH 7) of from 15 to 100, preferably 25 to 50.

[0100] The K value, also referred to as the intrinsic viscosity, is a parameter which is easy to determine by means of viscosity measurements of polymer solutions and is therefore frequently used in the industrial sector for characterizing polymers. For a certain sort of polymer, it is accepted under standardized measurement conditions on its own, depending on the average molar mass of the investigated sample and is calculated by means of the equation K value=1000 k according to the Fikentscher equation 1$k=\frac{1.51{g\eta }_r-1\pm \sqrt{1+\left(\frac{2}{c}+2+1.51{g\eta }_r\right)·1.51{g\eta }_r}}{150+300c}$

[0101] in which: ηr=relative viscosity (dynamic viscosity of the solution/dynamic viscosity of the solvent) and c=mass concentration of polymer in the solution (in g/cm3).

[0102] The polyurethanes containing acid groups are, after neutralization (partial or complete), water-soluble or dispersible without the aid of emulsifiers. The salts of the polyurethanes generally have better solubility or dispersibility in water than the unneutralized poly-urethanes. Bases which can be used for the neutralization of the polyurethanes are alkali metal bases, such as sodium hydroxide solution, potassium hydroxide solution, soda, sodium hydrogencarbonate, potassium carbonate or potassium hydrogencarbonate, and alkaline earth metal bases, such as calcium hydroxide, calcium oxide, magnesium hydroxide or magnesium carbonate, and ammonia and amines. 2-Amino-2-methylpropanol, diethylaminopropylamine and triisopropanolamine have proven particularly useful for the neutralization of the polyurethanes containing acid groups. The neutralization of the polyurethanes containing acid groups can also be carried out using mixtures of two or more bases, e.g. mixtures of sodium hydroxide solution and triisopropanolamine. Depending on the intended use, neutralization may be partial, e.g. up to 20 to 40%, or complete, i.e. 100%.

[0108] The polyurethanes are prepared as described above under 1). Charged cationic groups can be produced in the polyureas from the tertiary amino nitrogen atoms present either by protonation, e.g. with carboxylic acids, such as lactic acid, or by quaternization, e.g. with alkylating agents, such as C1-C4-alkyl halides, or sulfates. Examples of such alkylating agents are ethyl chloride, ethyl bromide, methyl chloride, methyl bromide, dimethyl sulfate and diethyl sulfate.

[0142] For the purposes of the present invention, water-soluble antioxidants, such as, for example, vitamins, e.g. ascorbic acid and derivatives thereof, can be used particularly advantageously.

[0143] A surprising property of the preparations according to the invention is that they are very good vehicles for cosmetic or dermatological active ingredients into the skin, preferred active ingredients being antioxidants which can protect the skin against oxidative stress. Preferred antioxidants here are vitamin E and derivatives thereof, and vitamin A and derivatives thereof.

[0144] The amount of antioxidants (one or more compounds) in the preparations is preferably 0.001 to 30% by weight, particularly preferably 0.05 to 20% by weight, in particular 0.1 to 10% by weight, based on the total weight of the preparation.

[0145] If vitamin E and/or derivatives thereof are the antioxidant(s), it is advantageous to choose their respective concentrations from the range from 0.001 to 10% by weight, based on the total weight of the formulation.

[0146] If vitamin A or vitamin A derivatives, or carotenes or derivatives thereof are the anti-oxidant(s), it is advantageous to choose their respective concentrations from the range from 0.001 to 10% by weight, based on the total weight of the formulation.

[0149] It is also advantageous to choose the active ingredients from the group of refatting substances, for example purcellin oil, Eucerit® and Neocerit®.

[0150] The active ingredient(s) is/are also particularly advantageously chosen from the group of NO synthase inhibitors, particularly if the preparations according to the invention are to be used for the treatment and prophylaxis of the symptoms of intrinsic and/or extrinsic skin aging and for the treatment and prophylaxis of the harmful effects of ultraviolet radiation on the skin.

[0151] A preferred NO synthase inhibitor is nitroarginine.

[0152] The active ingredient(s) is/are also advantageously chosen from the group which includes catechins and bile esters of catechins and aqueous or organic extracts from plants or parts of plants which have a content of catechins or bile esters of catechins, such as, for example, the leaves of the Theaceae plant family, in particular of the species Camellia sinensis (green tea). Particularly advantageous are typical ingredients thereof (such as e.g. polyphenols or catechins, caffeine, vitamins, sugars, minerals, amino acids, lipids).

[0153] Catechins are a group of compounds which are to be regarded as hydrogenated flavones or anthocyanidines and are derivatives of “catechin” (catechol, 3,3′,4′,5,7-flavanpentaol, 2-(3,4-dihydroxyphenyl)chroman-3,5,7-triol). Epicatechin ((2R,3R)-3,3′,4′,5,7-flavanpentaol) is also an advantageous active ingredient for the purposes of the present invention.

[0154] Also advantageous are plant extracts with a content of catechins, in particular extracts of green tea, such as e.g. extracts from leaves of plants of the species Camellia spec., very particularly the types of tea Camellia sinenis, C. assamica, C. taliensis and C. irrawadiensis and hybrids of these with, for example, Camellia japonica.

[0155] Preferred active ingredients are also polyphenols or catechins from the group (−)-catechin, (+)-catechin, (−)-catechin gallate, (−)-gallocatechin gallate, (+)-epicatechin, (−)-epicatechin, (−)-epicatechin gallate, (−)-epigallocatechin and (−)-epigallocatechin gallate.

[0156] Flavone and its derivatives (also often collectively called “flavones”) are also advantageous active ingredients for the purposes of the present invention. They are characterized by the following basic structure (substitution positions are shown): 9

[0157] Some of the more important flavones which can also preferably be used in preparations according to the invention are given in the table below:

[0158] In nature, flavones are usually in glycosylated form.

[0159] According to the invention, the flavonoids are preferably chosen chosen from the group of substances of the generic structural formula 10

[0160] where Z1 to Z7, independently of one another, are chosen from the group consisting of H, OH, alkoxy and hydroxyalkoxy, where the alkoxy and hydroxyalkoxy groups can be branched or unbranched and have 1 to 18 carbon atoms, and where Gly is chosen from the group of mono- and oligoglycoside radicals.

[0161] According to the invention, the flavonoids can however, also advantageously be chosen from the group of substances of the generic structural formula 11

[0162] where Z1 to Z6, independently of one another, are chosen from the group consisting of H, OH, alkoxy and hydroxyalkoxy, where the alkoxy and hydroxyalkoxy groups can be branched or unbranched and have 1 to 18 carbon atoms, and where Gly is chosen from the group of mono and oligoglycoside radicals.

[0163] Preferably, such structures can be chosen from the group of substances of the generic structural formula 12

[0164] where Gly1, Gly2 and Gly3, independently of one another, are monoglycoside radicals. Gly2 and Gly3 can also, individually or together, represent saturations by hydrogen atoms.

[0165] Preferably, Gly1, Gly2 and Gly3, independently of one another, are chosen from the group of hexosyl radicals, in particular of rhamnosyl radicals and glucosyl radicals. However, other hexosyl radicals, for example allosyl, altrosyl, galactosyl, gulosyl, idosyl, mannosyl and talosyl, can also be used advantageously in some circumstances. It may also be advantageous according to the invention to use pentosyl radicals.

[0166] Z1 to Z5 are, independently of one another, advantageously chosen from the group consisting of H, OH, methoxy, ethoxy and 2-hydroxyethoxy, and the flavone glycosides have the structure. 13

[0167] The flavone glycosides according to the invention are particularly advantageously chosen from the group given by the following structure: 14

[0168] where Gly1, Gly2 and Gly3, independently of one another, are monoglycoside radicals. Gly2 and Gly3 can also, individually or together, represent saturations by hydrogen atoms.

[0169] Preferably, Gly1, Gly2 and Gly3, independently of one another, are chosen from the group of hexosyl radicals, in particular of rhamnosyl radicals and glucosyl radicals. However, other hexosyl radicals, for example allosyl, altrosyl, galactosyl, gulosyl, idosyl, mannosyl and talosyl, can also advantageously be used in some circumstances. It may also be advantageous according to the invention to use pentosyl radicals.

[0170] For the purposes of the present invention, it is particularly advantageous to choose the flavone glucoside(s) from the group consisting of α-glucosylrutin, α-glucosylmyricetin, α-glucosylisoquercitrin, α-glucosylisoquercetin and α-glucosylquercitrin.

[0171] Particular preference is given, according to the invention, to α-glucosylrutin.

[0172] Also advantageous according to the invention are naringin (aurantin, naringenin-7-rhamnoglucoside), hesperidin (3′,5,7-trihydroxy-4′-methoxyflavanone-7-rutinoside, hesperidoside, hesperetin-7-O-rutinoside), rutin (3,3′,4′,5,7-pentahydroxyflyvone-3-rutinoside, quercetin-3-rutinoside, sophorin, birutan, rutabion, taurutin, phytomelin, melin), troxerutin (3,5-dihydroxy-3′,4′,7-tris(2-hydroxyethoxy)flavone-3-(6-O-(6-deoxy-α-L-mannopyranosyl)-β-D-glucopyranoside)), monoxerutin (3,3′,4′,5-tetrahydroxy-7-(2-hydroxyethoxy)flavone-3-(6-O-(6-deoxy- α-L-mannopyranosyl)-β-D-glucopyranoside)), dihydrorobinetin (3,3′,4′,5′,7-pentahydroxyflavanone), taxifolin (3,3′,4′,5,7-pentahydroxy-flavanone), eriodictyol-7-glucoside (3′,4′,5,7-tetrahydroxyflavanone-7 glucoside), flavanomarein (3′,4′,7,8-tetrahydroxyflavanone-7 glucoside) and isoquercetin (3,3′,4′,5,7-pentahydroxyflavanone-3-(β-D-glucopyranoside).

[0173] It is also advantageous to choose the active ingredient(s) from the group of ubiquinones and plastoquinones.

[0174] Ubiquinones are distinguished by the structural formula 15

[0175] and are the most widespread and thus the most investigated bioquinones. Ubiquinones are referred to depending on the number of isoprene units linked in the side chain as Q-1, Q-2, Q-3 etc., or depending on the number of carbon atoms, as U-5, U-10, U-15 etc. They preferably appear with certain chain lengths, e.g. in some microorganisms and yeasts where n=6. In most mammals including man, Q10 predominates.

[0176] Coenzyme Q10 is particularly advantageous and is characterized by the following structural formula: 16

[0177] Plastoquinones have the general structural formula 17

[0178] Plastoquinones differ in the number n of isoprene radicals and are referred to accordingly, e.g. PQ-9 (n=9). In addition, other plastoquinones with varying substituents on the quinone ring exist.

[0179] Creatine and/or creatine derivatives are preferred active ingredients for the purposes of the present invention. Creatine is characterized by the following structure: 18

[0180] Preferred derivatives are creatine phosphate and creatine sulfate, creatine acetate, creatine ascorbate and the derivatives esterified at the carboxyl group with mono- or polyfunctional alcohols.

[0181] A further advantageous active ingredient is L-carnitine [3-hydroxy-4-(trimethylammonio)-butyrobetaine]. Acylcarnitines which chosen from the group of substances of the following general structural formula 19

[0182] where R is chosen from the group of branched and unbranched alkyl radicals having up to 10 carbon atoms, are advantageous active ingredients for the purposes of the present invention. Preference is given to propionylcarnitine and, in particular, acetylcarnitine. Both enantiomers (D and L form) are to be used advantageously for the purposes of the present invention. It may also be advantageous to use any enantiomer mixtures, for example a racemate of D and L form.

[0183] Further advantageous active ingredients are sericoside, pyridoxol, vitamin K, biotin and aroma substances.

[0184] The list of said active ingredients and active ingredient combinations which can be used in the preparations according to the invention is, of course, not intended to be limiting. The active ingredients can be used individually or in any combinations with one another.

[0185] Skin aging is caused e.g. by endogenous, genetically determined factors. As a result of aging, the epidermis and dermis experience. e.g. the following structural damage and functional disorders, which can also be covered by the term “senile xerosis”:

[0186] a) dryness, roughness and formation of (dryness) wrinkles,

[0187] b) itching and

[0188] c) reduced refatting by sebaceous glands (e.g. after washing).

[0189] Exogenous factors, such as UV light and chemical noxae, can have a cumulative effect and, for example, accelerate or add to the endogenous aging processes. The epidermis and dermis experience, in particular as a result of exogenous factors, e.g. the following structural damage and functional disorders in the skin, which go beyond the degree and quality of the damage in the case of chronological aging:

[0190] d) visible vascular dilations (telangiectases, cuperosis);

[0191] e) flaccidity and formation of wrinkles;

[0192] f) local hyperpigmentation, hypopigmentation and abnormal pigmentation (e.g. age spots) and

[0193] g) increased susceptibility to mechanical stress (e.g. cracking).

[0194] Surprisingly, selected formulations according to the invention can also have an anti-wrinkle action or considerably increase the action of known antiwrinkle active ingredients. Accordingly, for the purposes of the invention, formulations are particularly advantageously suitable for the prophylaxis and treatment of cosmetic or dermatological skin changes, as arise, for example, during skin aging. They are also advantageously suitable for combating the development of dry or rough skin.

[0195] In a particular embodiment, the present invention thus relates to products for the care of skin aged in a natural manner, and for the treatment of the secondary damage of light aging, in particular the phenomena listed under a) to g).

[0196] The water phase of the preparations according to the invention can advantageously comprise customary cosmetic auxiliaries, such as, for example, alcohols, in particular those of low carbon number, preferably ethanol and/or isopropanol, diols or polyols of low carbon number, and ethers thereof, preferably propylene glycol, glycerol, ethylene glycol, ethylene glycol monoethyl or monobutyl ether, propylene glycol monomethyl, monoethyl or monobutyl ether, diethyleneglycol monomethyl or monoethyl ether and analogous products, polymers, foam stabilizers, electrolytes and moisturizers.

[0197] Moisturizers is the term used to describe substances or mixtures of substances which, following application or distribution on the surface of the skin, confer on cosmetic or dermatological preparations the property of reducing the moisture loss by the horny layer (also called transepidermal water loss (TEWL)) and/or have a beneficial effect on the hydration of the horny layer.

[0198] Advantageous moisturizers for the purposes of the present invention are, for example, glycerol, lactic acid, pyrrolidonecarboxylic acid and urea. In addition, it is particularly advantageous to use polymeric moisturizers from the group of polysaccharides which are soluble in water and/or swellable in water and/or gellable using water. Particularly advantageous are, for example, hyaluronic acid, chitosan and/or a fucose-rich polysaccharide which is listed in Chemical Abstracts under the registry number 178463-23-5 and is available, for example, under the name Fucogel®1000 from SOLABIA S.A.

[0199] The cosmetic and dermatological preparations according to the invention can comprise dyes and/or color pigments, particularly when they are in the form of decorative cosmetics. The dyes and color pigments can be chosen from the corresponding positive list of the Cosmetics Directive or the EC list of cosmetic colorants. In most cases they are identical to the dyes approved for foods. Advantageous color pigments are, for example, titanium dioxide, mica, iron oxides (e.g. Fe2O3, Fe3O4, FeO(OH)) and/or tin oxide. Advantageous dyes are, for example, carmine, Berlin blue, chrome oxide green, ultramarine blue and/or manganese violet. It is particularly advantageous to choose the dyes and/or color pigments from the following list. The Colour Index Numbers (CIN) are taken from the Rowe Colour Index, 3rd Edition, Society of Dyers and Colourists, Bradford, England, 1971.

[0203] 1. Natural pearlescent pigments, such as, for example

[0204] “pearl essence” (guanine/hypoxanthin mixed crystals from fish scales) and

[0205] “mother of pearl” (ground mussel shells)

[0206] 2. Monocrystalline pearlescent pigments, such as, for example, bismuth oxychloride (BiOCI)

[0207] 3. Layer-substrate pigments: e.g. mica/metal oxide

[0208] Bases for pearlescent pigments are, for example, pulverulent pigments or castor oil dispersions of bismuth oxychloride and/or titanium dioxide, and bismuth oxychloride and/or titanium dioxide on mica. The luster pigment listed under CIN 77163, for example, is particularly advantageous.

[0210] Particular preference is given, for example, to the pearlescent pigments obtainable from Merck under the trade names Timiron, Colorona or Dichrona.

[0211] The list of given pearlescent pigments is not of course intended to be limiting.

[0212] Pearlescent pigments which are advantageous for the purposes of the present invention are obtainable by numerous methods known per se. For example, other substrates apart from mica can be coated with further metal oxides, such as, for example, silica and the like. SiO2 particles coated with, for example, TiO2 and Fe2O3 (“ronaspheres”), which are marketed by Merck and are particularly suitable for the optical reduction of fine lines are advantageous.

[0213] It can moreover be advantageous to dispense completely with a substrate such as mica. Particular preference is given to iron pearlescent pigments prepared without the use of mica. Such pigments are obtainable, for example, under the trade name Sicopearl Kupfer 1000 from BASF.

[0214] In addition, also particularly advantageous are effect pigments which are obtainable under the trade name Metasome Standard/Glitter in various colors (yellow, red, green, blue) from Flora Tech. The glitter particles are present here in mixtures with various auxiliaries and dyes (such as, for example, the dyes with the Colour Index (CI) Numbers 19140, 77007, 77289, 77491).

[0215] The dyes and pigments may be present either individually or in a mixture, and can be mutually coated with one another, different coating thicknesses generally giving rise to different color effects. The total amount of dyes and color-imparting pigments is advantageously chosen from the range from e.g. 0.1% by weight to 30% by weight, preferably from 0.5 to 15% by weight, in particular from 1.0 to 10% by weight, in each case based on the total weight of the preparations.

[0216] For the purposes of the present invention, it is also advantageous to provide cosmetic and dermatological preparations whose main purpose is not protection against sunlight, but which nevertheless have a content of UV protection substances. Thus, for example, UV-A and/or UV-B filter substances are usually incorporated into day creams or make-up products. UV protection substances, like antioxidants, and, if desired, preservatives, also constitute effective protection of the preparations themselves against spoilage. Also favorable are cosmetic and dermatological preparations in the form of a sunscreen.

[0217] Accordingly, for the purposes of the present invention, as well as comprising one or more UV filter substances according to the invention, the preparations additionally comprise at least one further UV-A and/or UV-B filter substance. The formulations may, although not necessarily, optionally also comprise one or more organic and/or inorganic pigments as UV filter substances which may be present in the water and/or oil phase.

[0218] Preferred inorganic pigments are metal oxides and/or other metal compounds which are insoluble or virtually insoluble in water, in particular oxides of titanium (TiO2), zinc (ZnO), iron (e.g. Fe2O3), zirconium (ZrO2), silicon (SiO2), manganese (e.g. MnO), aluminum (Al2O3), cerium (e.g. Ce2O3), mixed oxides of the corresponding metals and mixtures of such oxides.

[0219] For the purposes of the present invention, such pigments may advantageously be surface-treated (“coated”), the intention being to form or retain, for example, an amphiphilic or hydrophobic character. This surface treatment can consist in providing the pigments with a thin hydrophobic layer by processes known per se.

[0220] Advantageous according to the invention are e.g. titanium dioxide pigments which have been coated with octylsilanol. Suitable titanium dioxide particles are available under the trade name T805 from Degussa. Also particularly advantageous are TiO2 pigments coated with aluminum stearate, e.g. those available under the trade name MT 100 T from TAYCA.

[0221] A further advantageous coating of the inorganic pigments consists of dimethyl-polysiloxane (also: dimethicone), a mixture of completely methylated, linear siloxane polymers which have been terminally blocked with trimethylsiloxy units. Particularly advantageous for the purposes of the present invention are zinc oxide pigments which have been coated in this way.

[0222] Also advantageous is a coating of the inorganic pigments with a mixture of dimethyl-polysiloxane, in particular dimethylpolysiloxane having an average chain length of from 200 to 350 dimethylsiloxane units, and silica gel, which is also referred to as simethicone. In particular, it is advantageous for the inorganic pigments to be additionally coated with aluminum hydroxide or aluminum oxide hydrate (also: alumina, CAS No.: 1333-84-2). Particularly advantageous are titanium dioxides which have been coated with simethicone and alumina, it also being possible for the coating to comprise water. An example thereof is the titanium dioxide available under the trade name Eusolex T2000 from Merck.

[0223] An advantageous organic pigment for the purposes of the present invention is 2,2′-methylenebis(6-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol) [INCI: bisoctyltriazole], which is characterized by the chemical structural formula 20

[0224] and is available under the trade name Tinosorb® M from CIBA-Chemikalien GmbH.

[0225] Preparations according to the invention advantageously comprise substances which absorb UV radiation in the UV-A and/or UV-B range, the total amount of filter substances being, for example, from 0.1 % by weight to 30% by weight, preferably from 0.5 to 20% by weight, in particular from 1.0 to 15.0% by weight, based on the total weight of the preparations, in order to provide cosmetic preparations which protect the hair and the skin from the entire range of ultraviolet radiation. They can also be used as sunscreens for the hair or the skin.

[0226] Advantageous UV-A filter substances for the purposes of the present invention are dibenzoylmethane derivatives, in particular 4-(tert-butyl)-4′-methoxydibenzoylmethane (CAS No. 70356-09-1), which is sold by Givaudan under the name Parsol® 1789 and by Merck under the trade name Eusolex(® 9020.

[0227] Further advantageous UV-A filter substances are phenylene-1,4-bis(2-benzimidazyl)-3,3′-5,5′-tetrasulfonic acid: 21

[0228] and its salts, particularly the corresponding sodium, potassium or triethanolammonium salts, in particular phenylene-1,4-bis(2-benzimidazyl)-3,3′-5,5′-tetrasulfonic bis-sodium salt: 22

[0229] with the INCI name Bisimidazylate, which is available, for example, under the trade name Neo Heliopan AP from Haarmann & Reimer.

[0230] Also advantageous are 1,4-di(2-oxo-10-sulfo-3-bornylidenemethyl)benzene and salts thereof (in particular the corresponding 10-sulfato compounds, in particular the corresponding sodium, potassium or triethanolammonium salt), which is also referred to as benzene-1,4-di(2-oxo-3-bornylidenemethyl-10-sulfonic acid) and is characterized by the following structure: 23

[0231] Advantageous UV filter substances for the purposes of the present invention are also broadband filters, i.e. filter substances which absorb both UV-A and also UV-B radiation.

[0232] Advantageous broadband filters or UV-B filter substances are, for example, bisresorcinyltriazine derivatives having the following structure: 24

[0233] where R1, R2 and R3 independently of one another are chosen from the group of branched and unbranched alkyl groups having 1 to 10 carbon atoms, or are a single hydrogen atom. Particular preference is given to 2,4-bis{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: Aniso Triazine), which is available under the trade name Tinosorb® S from CIBA-Chemikalien GmbH

[0234] For the purposes of the present invention, particularly advantageous preparations which are characterized by high or very high UV-A protection preferably comprise two or more UV-A and/or broadband filters, in particular dibenzoylmethane derivatives [for example 4-(tert-butyl)-4′-methoxydibenzoylmethane], benzotriazole derivatives [for example 2,2′-methylenebis(6-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol)], phenylene-1,4-bis(2-benzimidazyl)-3,3′-5,5′-tetrasulfonic acid and/or its salts, 1,4-di(2-oxo-10-sulfo-3-bornylidenemethyl)benzene and/or salts thereof and/or 2,4-bis{[4-(2-ethylhexyloxy)-2-hydroxy]phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine, in each case individually or in any combinations with one another.

[0235] Other UV filter substances, which have the structural formula 25
