Description:
[0001]    This invention relates generally to cosmetic preparations and, more particularly, to hair care preparations which contain natural oils containing unsaturated fatty acids and sterols and which are used to strengthen the hair and to stimulate hair growth.  
         PRIOR ART  
         [0002]    Every year, new products in the form of hair care and hair treatment preparations intended to counteract hair loss are brought onto the market. There are many reasons why keratin fibers die off and fall out. On the one hand, environmental influences can have a damaging effect on the hair and hair roots; on the other hand, the hair is seriously damaged by treatment with aggressive chemicals of which residues always remain on the hair and scalp after coloring, bleaching or even washing. This causes the hair to thin out, as does frequent or intensive styling. However, the most common cause is hormonal and mainly affects the male population because the main influence is exerted by androgens.  
           [0003]    It is known that sterols and especially β-sitosterol have an anti-androgenic effect. β-Sitosterol inhibits the enzyme 5-α-reductase and acts not only on the typically androgenic phenomenon of prostate hyperplasia, but also on androgenetic alopecia, i.e. hair loss initiated by male hormones. The main active component in Finasterid®, which is being successfully used against male hair loss, is also a steroid, albeit on a synthesic basis.  
           [0004]    Sterols as hair growth stimulators are described in U.S. Pat. No. 6,156,296. They are used in combination with α-hydroxycarboxylic acids in hair care preparations. Unsaturated fatty acids, such as the multi-unsaturated C18 acids for example, are also known as antiandrogenic agents. CLA (conjugated linoleic acid) is known to have a narrowing effect on the cell membranes in the muscles and the surrounding tissue and to allow fats easy access to this region of the body where they produce energy and size growth.  
           [0005]    In order to be able to develop their effect, it is important for the active components to be thoroughly taken up by the hair and scalp. The concentrations used are generally relatively high.  
           [0006]    Accordingly, the problem addressed by the present invention was to provide preparations which would have an improved hair-growth-stimulating effect and hair-strengthening effect. In addition, the preparations according to the invention would cause less damage to the hair after application and would stabilize the hair and thus contribute towards maintaining the hair structure. These preparations would also show high dermatological compatibility and would be distinguished by high stability during storage at elevated temperatures.  
         DESCRIPTION OF THE INVENTION  
         [0007]    The present invention relates to hair care preparations comprising natural oils which contain—based on the quantity of oils— 
           [0008]    (a) 0.01 to 5% by weight sterols and  
           [0009]    (b) 0.1 to 90% by weight unsaturated fatty acids,  
           [0010]    and to the use of these hair care preparations for preventing androgenetic alopecia and for stimulating hair growth.  
           [0011]    The present invention also relates to the use of natural oils containing 0.01 to 5% by weight sterols and 0.1 to 90% by weight unsaturated fatty acids for the production of hair care preparations.  
           [0012]    It has surprisingly been found that the effectiveness of sterols and unsaturated fatty acids in stimulating hair growth, caring for damaged hair and strengthening the hair is far greater when they are used within natural oils in hair care preparations. The presence of the oils has a caring and protective effect against environmental influences and mechanical stress, particularly in the case of damaged and dry hair, and on the other hand increases the availability of the active components against hormonal influences. Above all, the combination of sterols with unsaturated fatty acids shows improved effectiveness against hair loss. In addition, such preparations also lead prophylactically to reduced damage to the hair structure and thus contribute towards maintaining the hair structure. Natural oils containing sterols and unsaturated fatty acids The preparations according to the invention contain 0.1 to 10% by weight, preferably 1 to 5% by weight and more particularly 2 to 3% by weight of the natural oils containing sterols and unsaturated fatty acids. Natural oils in the context of the invention are understood to be oils of animal and preferably vegetable origin. The natural oils in question are esters of linear C 6-22  fatty acids with linear C 6-22  fatty alcohols, esters of branched C 6-13  carboxylic acids with linear C 6-22  fatty alcohols such as, for example, myristyl myristate, myristyl palmitate, myristyl stearate, myristyl isostearate, myristyl oleate, myristyl behenate, myristyl erucate, cetyl myristate, cetyl palmitate, cetyl stearate, cetyl isostearate, cetyl oleate, cetyl behenate, cetyl erucate, stearyl myristate, stearyl palmitate, stearyl stearate, stearyl isostearate, stearyl oleate, stearyl behenate, stearyl erucate, isostearyl myristate, isostearyl palmitate, isostearyl stearate, isostearyl isostearate, isostearyl oleate, isostearyl behenate, isostearyl oleate, oleyl myristate, oleyl palmitate, oleyl stearate, oleyl isostearate, oleyl oleate, oleyl behenate, oleyl erucate, behenyl myristate, behenyl palmitate, behenyl stearate, behenyl isostearate, behenyl oleate, behenyl behenate, behenyl erucate, erucyl myristate, erucyl palmitate, erucyl stearate, erucyl isostearate, erucyl oleate, erucyl behenate and erucyl erucate. Also suitable are triglycerides based on C 6-10  fatty acids, liquid mono-/di-/triglyceride mixtures based on C 8-18  fatty acids.  
           [0013]    The tocopherols, sterols and/or carotinoids may be added to these oils although, preferably, they are already present in native form in the oil. The commercial products of Aarhus Oliefabrik A/S, Aarhus, Denmark, known under the name of Cremeol®, now Cegesoft® (Cognis, Düsseldorf), are preferred. They include  
           [0014]    Cegesoft®) (formerly Cremeol®) PS 6, vegetable oil, C18:1 84%, C18:2 5%, unsaponifiable matter (mainly phytosterols, e.g. β-sitosterol, campesterol) 1.1%, tocopherols 1,400 ppm

           [0017]    Cegesoft®) (formerly Cremeol®) SH, shorea stenoptera butter, C18:1 35%, C18:2 1%, unsaponifiable matter (triterpenes and sterols) 1.4% (of which 31.5% triterpenes, 4-desmethylsterols 65.3%+α-methylsterols 3.2%)  
           [0018]    Cegesoft®) (formerly Cremeol®) SBE, shea butter ( Butyrospermum parkii ) extract, C18:1 63.4%, C18:2 1.8%, unsaponifiable matter: 30-40%, of which triterpene alcohols 85%, sterols 8%; tocopherols 1,400 ppm  
           [0019]    Also suitable are the oils marketed under the name of Akorex® by Karlshamns AB, Karlshamn, Sweden, which also contain high levels of unsaturated fatty acids and sterols  
           [0020]    Accordingly, phytosterols are mainly used as sterols. Examples include sitosterol, campesterol, brassicasterol, lupenol, stigmasterol, α-spinasterol and avennasterol. β-sitosterol and campesterol are particularly preferred. The sterols are present in the oils in quantities of 0.01 to 5% by weight, preferably 0.1 to 3% by weight and more particularly 1 to 2% by weight.  
           [0021]    In the context of the present invention, the unsaturated fatty acids are understood to be aliphatic carboxylic acids which contain an aliphatic, linear or branched acyl group containing 6 to 22 carbon atoms and 1, 2 or 3 double bonds. Fatty acids containing 16 to 18 carbon atoms are preferred. Of these, the C18 acids oleic acid, linoleic acid and linolenic acid and isomers thereof, such as conjugated linoleic acid for example, are particularly preferred. The unsaturated fatty acids are present in the natural oils used in quantities of 0.1 to 90% by weight, preferably in quantities of 10 to 80% by weight and more particularly in quantities of 30 to 70% by weight.  
           [0022]    Alkyl and/or Alkenyl Oligo-Glycosides  
           [0023]    Alkyl and alkenyl oligoglycosides are known nonionic surfactants corresponding to formula (I):  
           R 1 O- 13  [G] p   (I) 
           [0024]    in which R 1  is an alkyl and/or alkenyl group containing 4 to 22 carbon atoms, G is a sugar unit containing 5 or 6 carbon atoms and p is a number of 1 to 10. They may be obtained by the relevant methods of preparative organic chemistry. EP-A1 0301298 and WO 90/03977 are cited as representative of the extensive literature available on the subject. The alkyl and/or alkenyl oligoglycosides may be derived from aldoses or ketoses containing 5 or 6 carbon atoms, preferably glucose. Accordingly, the preferred alkyl and/or alkenyl oligoglycosides are alkyl and/or alkenyl oligoglucosides. The index p in general formula (I) indicates the degree of oligomerization (DP), i.e. the distribution of mono- and oligoglycosides, and is a number of 1 to 10. Whereas p in a given compound must always be an integer and, above all, may assume a value of 1 to 6, the value p for a certain alkyl oligoglycoside is an analytically determined calculated quantity which is generally a broken number. Alkyl and/or alkenyl oligoglycosides having an average degree of oligomerization p of 1.1 to 3.0 are preferably used. Alkyl and/or alkenyl oligoglycosides having a degree of oligomerization of less than 1.7 and, more particularly, between 1.2 and 1.4 are preferred from the applicational point of view. The alkyl or alkenyl radical R 1  may be derived from primary alcohols containing 4 to 11 and preferably 8 to 10 carbon atoms. Typical examples are butanol, caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and the technical mixtures thereof obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the hydrogenation of aldehydes from Roelen&#39;s oxosynthesis. Alkyl oligoglucosides having a chain length of C 8  to C 10  (DP =1 to 3), which are obtained as first runnings in the separation of technical C 8-18  coconut oil fatty alcohol by distillation and which may contain less than 6% by weight of C 12  alcohol as an impurity, and also alkyl oligo-glucosides based on technical C 9-11  oxoalcohols (DP=1 to 3) are preferred. In addition, the alkyl or alkenyl radical R 1  may also be derived from primary alcohols containing 12 to 22 and preferably 12 to 14 carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmitoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and technical mixtures thereof which may be obtained as described above. Alkyl oligoglucosides based on hydrogenated C 12/14  cocoalcohol with a DP of 1 to 3 are preferred. Alkyl and/or alkenyl oligoglucosides may be added to the compositions according to the invention in quantities of 0 to 10% by weight, preferably 0.5 to 5% by weight and more particularly 1 to 3% by weight.  
           [0025]    Esterquats  
           [0026]    “Esterquats” are generally understood to be quaternized fatty acid triethanolamine ester salts. They are known compounds which may be obtained by the relevant methods of preparative organic chemistry, cf. International patent application WO 91/01295 (Henkel), in which triethanolamine is partly esterified with fatty acids in the presence of hypophosphorous acid, air is passed through the reaction mixture and the whole is then quaternized with dimethyl sulfate or ethylene oxide. In addition, DE-C1 4308794 (Henkel) describes a process for the production of solid esterquats in which the quaternization of triethanolamine esters is carried out in the presence of suitable dispersants, preferably fatty alcohols. Overviews of this subject have been published, for example, by R. Puchta et al. in  Tens. Surf. Det.,  30, 186 (1993), by M. Brock in  Tens. Surf. Det.,  30, 394 (1993), by R. Lagerman et al. in  J. Am. Oil Chem. Soc.,  71, 97 (1994) and by 1. Shapiro in  Cosm. Toil.  109, 77 (1994). The quaternized fatty acid triethanolamine ester salts correspond to formula (II):  
                         
 
           [0027]    in which R 2 CO is an acyl group containing 6 to 22 carbon atoms, R 3  and R 4  independently of one another represent hydrogen or have the same meaning as R 2 CO, R 5  is an alkyl group containing 1 to 4 carbon atoms or a (CH 2 CH 2 O) q H group, m, n and p together stand for 0 or numbers of 1 to 12, q is a number of 1 to 12 and X is halide, alkyl sulfate or alkyl phosphate. Typical examples of esterquats which may be used in accordance with the present invention are products based on caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, isostearic acid, stearic acid, oleic acid, elaidic acid, arachic acid, behenic acid and erucic acid and the technical mixtures thereof obtained, for example, in the pressure hydrolysis of natural fats and oils. Technical C 12/18  cocofatty acids and, in particular, partly hydrogenated C 16/18  tallow or palm oil fatty acids and C 16/18  fatty acid cuts rich in elaidic acid are preferably used. To produce the quaternized esters, the fatty acids and the triethanolamine may be used in a molar ratio of 1.1:1 to 3:1. With the performance properties of the esterquats in mind, a ratio of 1.2:1 to 2.2:1 and preferably 1.5:1 to 1.9:1 has proved to be particularly advantageous. The preferred esterquats are technical mixtures of mono-, di- and triesters with an average degree of esterification of 1.5 to 1.9 and are derived from technical C 16/18  tallow or palm oil fatty acid (iodine value 0 to 40). In performance terms, quaternized fatty acid triethanolamine ester salts corresponding to formula (II), in which R 2 CO is an acyl group containing 16 to 18 carbon atoms, R 3  has the same meaning as R 2 CO, R 4  is hydrogen, R 5  is a methyl group, m, n and p stand for 0 and X stands for methyl sulfate, have proved to be particularly advantageous. Besides the quaternized fatty acid triethanolamine ester salts, other suitable esterquats are quaternized ester salts of fatty acids with diethanol-alkyamines corresponding to formula (Ill):  
                         
 
           [0028]    in which R 2 CO is an acyl group containing 6 to 22 carbon atoms, R 3  is hydrogen or has the same meaning as R 2 CO, R 4  and R 5  independently of one another are alkyl groups containing 1 to 4 carbon atoms, m and n together stand for 0 or numbers of 1 to 12 and X stands for halide, alkyl sulfate or alkyl phosphate. Finally, another group of suitable esterquats are the quaternized ester salts of fatty acids with 1,2-dihydroxypropyl dialkylamines corresponding to formula (IV):  
                         
 
           [0029]    in which R 2 CO is an acyl group containing 6 to 22 carbon atoms, R 2  is hydrogen or has the same meaning as R 2 CO, R 4 , R 5  and R 6  independently of one another are alkyl groups containing 1 to 4 carbon atoms, m and n together stand for 0 or numbers of 1 to 12 and X stands for halide, alkyl sulfate or alkyl phosphate. So far as the choice of the preferred fatty acids and the optimal degree of esterification are concerned, the examples mentioned for (II) also apply to the esterquats corresponding to formulae (III) and (IV). The esterquats are normally marketed in the form of 50 to 90% by weight solutions in alcohol which may readily be diluted with water as required. Esterquats may be present in the hair care preparations in quantities of 0 to 10% by weight, preferably 1 to 5% by weight and more particularly 1.5 to 3% by weight.  
           [0030]    Commercial Applications  
           [0031]    Formulations which remain on the hair or the scalp for a relatively long time are particularly suitable for developing the antiandrogenic effect. Such formulations include hair treatments, hair packs, hair lotions, hair gels, hair colors, blonding preparations, permanent wave preparations. The formulations are particularly suitable for long-term application with a prophylactic effect. Besides preventing androgenetic alopecia and stimulating hair growth, however, the preparations may also be used for treating dry scalp and dandruff and against inflammatory scalp and antiageing effects.  
           [0032]    Cosmetic and/or Pharmaceutical Preparations  
           [0033]    The hair care preparations according to the invention may contain surfactants, co-emulsifiers, superfatting agents, pearlizing waxes, consistency factors, polymers, silicone compounds, waxes, stabilizers, antidandruff agents, film formers, swelling agents, hydrotropes, preservatives, solubilizers, complexing agents, reducing agents, alkalizing agents, antioxidants, perfume oils and the like as additional auxiliaries and additives.  
           [0034]    Other preferred auxiliaries and additives are anionic and/or amphoteric or zwitterionic surfactants. Typical examples of anionic surfactants are soaps, alkyl benzenesulfonates, alkanesulfonates, olefin sulfonates, alkylether sulfonates, glycerol ether sulfonates, α-methyl ester sulfonates, sulfofatty acids, alkyl sulfates, fatty alcohol ether sulfates, glycerol ether sulfates, fatty acid ether sulfates, hydroxy mixed ether sulfates, monoglyceride (ether) sulfates, fatty acid amide (ether) sulfates, mono- and dialkyl sulfosuccinates, mono- and dialkyl sulfosuccinamates, sulfotriglycerides, amide soaps, ether carboxylic acids and salts thereof, fatty acid isethionates, fatty acid sarcosinates, fatty acid taurides, N-acylamino acids such as, for example, acyl lactylates, acyl tartrates, acyl glutamates and acyl aspartates, alkyl oligoglucoside sulfates, protein fatty acid condensates (particularly wheat-based vegetable products) and alkyl—(ether) phosphates. If the anionic surfactants contain polyglycol ether chains, they may have a conventional homolog distribution although they preferably have a narrow-range homolog distribution. Typical examples of amphoteric or zwitterionic surfactants are alkylbetaines, alkylamidobetaines, aminopropionates, aminoglycinates, imidazolinium betaines and sulfobetaines. The surfactants mentioned are all known compounds. Information on their structure and production can be found in relevant synoptic works, cf. for example J. Falbe (ed.), “ Surfactants in Consumer Products ”, Springer Verlag, Berlin, 1987, pages 54 to 124 or J. Falbe (ed.), “ Katalysatoren, Tenside und Mineralöladditive (Catalysts, Surfactants and Mineral Oil Additives) ”, Thieme Verlag, Stuttgart, 1978, pages 123-217. The percentage content of surfactants in the preparations may be from 0.1 to 10% by weight and is preferably from 0.5 to 5% by weight, based on the preparation.  
           [0035]    Other surfactants may also be added to the hair care preparations as co-emulsifiers, including for example  
           [0036]    (1) products of the addition of 2 to 30 mol ethylene oxide and/or 0 to 5 mol propylene oxide onto linear C 8-22  fatty alcohols, onto C 12-22  fatty acids and onto alkyl phenols containing 8 to 15 carbon atoms in the alkyl group;  
           [0037]    (2) C 12/18  fatty acid monoesters and diesters of addition products of 1 to 30 mol ethylene oxide onto glycerol;  
           [0038]    (3) glycerol mono- and diesters and sorbitan mono- and diesters of saturated and unsaturated fatty acids containing 6 to 22 carbon atoms and ethylene oxide addition products thereof;  
           [0039]    (4) addition products of 15 to 60 mol ethylene oxide onto castor oil and/or hydrogenated castor oil;  
           [0040]    (5) polyol esters and, in particular, polyglycerol esters such as, for example, polyglycerol polyricinoleate, polyglycerol poly-12-hydroxystearate or polyglycerol dimerate isostearate. Mixtures of compounds from several of these classes are also suitable;  
           [0041]    (6) addition products of 2 to 15 mol ethylene oxide onto castor oil and/or hydrogenated castor oil;  
           [0042]    (7) partial esters based on linear, branched, unsaturated or saturated C 6/22  fatty acids, ricinoleic acid and 12-hydroxystearic acid and glycerol, polyglycerol, pentaerythritol, dipentaerythritol, sugar alcohols (for example sorbitol), alkyl glucosides (for example methyl glucoside, butyl glucoside, lauryl glucoside) and polyglucosides (for example cellulose);  
           [0043]    (8) mono-, di and trialkyl phosphates and mono-, di- and/or tri-PEG-alkyl phosphates and salts thereof;  
           [0044]    (9) wool wax alcohols;  
           [0045]    (10) polysiloxane/polyalkyl polyether copolymers and corresponding derivatives;  
           [0046]    (11) mixed esters of pentaerythritol, fatty acids, citric acid and fatty alcohol according to DE 1165574 PS and/or mixed esters of C 6-22  fatty acids, methyl glucose and polyols, preferably glycerol or polyglycerol,  
           [0047]    (12) polyalkylene glycols and  
           [0048]    (13) glycerol carbonate.  
           [0049]    The addition products of ethylene oxide and/or propylene oxide onto fatty alcohols, fatty acids, alkylphenols, glycerol mono- and diesters and sorbitan mono- and diesters of fatty acids or onto castor oil are known commercially available products. They are homolog mixtures of which the average degree of alkoxylation corresponds to the ratio between the quantities of ethylene oxide and/or propylene oxide and substrate with which the addition reaction is carried out. C 12/18  fatty acid monoesters and diesters of addition products of ethylene oxide onto glycerol are known as lipid layer enhancers for cosmetic formulations from DE 2024051 PS.  
           [0050]    Other suitable emulsifiers are zwitterionic surfactants. Zwitterionic surfactants are surface-active compounds which 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-dimethyl ammonium glycinates, for example cocoalkyl dimethyl ammonium glycinate, N-acylaminopropyl-N,N-dimethyl ammonium glycinates, for example cocoacylaminopropyl dimethyl ammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethyl imidazolines containing 8 to 18 carbon atoms in the alkyl or acyl group and cocoacylaminoethyl hydroxyethyl carboxymethyl glycinate. The fatty acid amide derivative known under the CTFA name of Cocamidopropyl Betaine is particularly preferred. Ampholytic surfactants are also suitable emulsifiers. Ampholytic surfactants are surface-active compounds which, in addition to a C 8/18  alkyl or acyl group, contain at least one free amino group and at least one —COOH— or —SO 3 H— group in the molecule and which are capable of forming inner salts. Examples of suitable ampholytic surfactants are N-alkyl glycines, N-alkyl propionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropyl glycines, N-alkyl taurines, N-alkyl sarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids containing around 8 to 18 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-coco-alkylaminopropionate, cocoacylaminoethyl aminopropionate and C 2/18  acyl sarcosine.  
           [0051]    Superfatting agents may be selected from such substances as, for example, lanolin and lecithin and also polyethoxylated or acylated lanolin and lecithin derivatives, polyol fatty acid esters, monoglycerides and fatty acid alkanolamides, the fatty acid alkanolamides also serving as foam stabilizers.  
           [0052]    The consistency factors mainly used are fatty alcohols or hydroxyfatty alcohols containing 12 to 22 and preferably 16 to 18 carbon atoms and also partial glycerides, fatty acids or hydroxyfatty acids. A combination of these substances with alkyl oligoglucosides and/or fatty acid N-methyl glucamides of the same chain length and/or polyglycerol poly-12-hydroxystearates is preferably used.
