Hair preparation for the treatment of dandruff

BACKGROUND OF THE INVENTION

[0001] The present invention relates to cosmetic preparations, in particular antidandruff compositions and deodorizing cosmetic compositions, comprising Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl)ethanone oxime or salts thereof from inorganic and organic acids, in, particular Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl)ethanone oxime nitrate (oxiconazole nitrate).

[0002] The fungicidal effectiveness of Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl)ethanone oxime nitrate (oxiconazole nitrate) is, as described in the publication Arzneim.-Forsch./Drug Res. 29 (II), No.10 (1979), p. 1510 ff, known.

[0003] The use of oxiconazole nitrate in broad-spectrum antimycotics for the curative treatment of dermatological disorders is described in U.S. Pat. No. 5,648,389. The compositions described therein for the treatment of acne comprise, in addition to an antimicrobial active ingredient, one or more hydroxy acid(s) and a water-soluble zinc compound.

[0004] WO 96/29045 proposes compositions for the treatment of scalp dermatitis consisting of a combination of cytotoxic agents, for example zinc pyrithione or selenium sulfide and a fungicide, for example oxiconazole.

[0005] It has now been found that Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl)ethanone oxime and salts thereof, in particular the nitrate, can be used as antidandruff agents in cosmetic preparations.

SUMMARY OF THE INVENTION

[0006] Surprisingly it has been found that said cosmetic preparations can be free of other active substances. In particular they can be free of cytotoxic agents like zinc pyrithione or selenium sulfide.

[0007] The invention provides cosmetic preparations comprising Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl)ethanone oxime or salts thereof. In this connection, suitable salts are, preferably, the nitrate, chloride, bromide, perchlorate or acetate. Particular preference is given to the nitrate.

[0008] The Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl)-ethanone oxime and salts thereof to be used in the cosmetic preparations can, for example be prepared by a process as described in the publication Arzneim.-Forsch./Drug Res. 29 (II), No.10 (1979), p. 1510 ff.

[0009] In particular the invention relates to cosmetic preparations which are free of cytotoxic agents like zinc pyrithione or selenium sulfide.

[0010] For the use according to the invention of said compounds, a very wide variety of cosmetic preparations are suitable, in particular shampoos. Examples of further preparations which are suitable in accordance with the invention and which may be mentioned are the following hair care and styling compositions: hair rinses, hair treatments, hair regenerators, hair lotions, water-wave lotions, hair sprays, styling creams, styling gels, hair oils, hair pomades or hair brilliantines.

These are homolog mixtures whose average degree of alkoxylation corresponds to the ratio of the amounts of ethylene oxide and/or propylene oxide and substrate with which the addition reaction is carried out. C12-C18-Fatty acid mono- and diesters of addition products of ethylene oxide with glycerol are known from DE 20 24 051 as refatting agents for cosmetic preparations.

[0026] Superfatting agents which can be used are substances such as, for example, polyethoxylated lanolin derivatives, lecithin derivatives, polyol fatty acid esters, monoglycerides and fatty acid alkanolamides, the latter also serving as foam stabilizers. Typical examples of fats are glycerides, and suitable waxes are inter alia beeswax, paraffin wax or microcrystalline waxes, optionally in combination with hydrophilic waxes, e.g. cetystearyl alcohol.

[0027] Stabilizers which can be used are metal salts of fatty acids, such as, for example, magnesium, aluminum and/or zinc stearate.

[0036] In order to improve the affinity of Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl)ethanone oxime used according to the invention, or salts thereof on the skin or scalp, it is possible to use cationic guar polymers in weight amounts of from 0.01 to 5.0%, preferably 0.02 to 1.0%, as described in WO 97/26854. The effect of the active ingredient used according to the invention can be improved by adding polyethylene glycol (PEG), in particular having 6 to 22 EO groups, preferably PEG-12, polypropylene glycol (PPG), polyethoxy/polypropoxy copolymers, polyethyleneimines, polyethoxylated polyethyleneimines, polyethylene oxide fatty acid glycerides, ethoxylated nonylphenol, ethoxylated alcohols, polyethylene carbohydrates. Silicones, polyalkylsiloxanes, polyalkylarylsiloxanes, polyethersiloxane copolymers, as described in U.S. Pat. No. 5104645 and publications cited therein, improve the care action of the compositions according to the invention. The preparations according to the invention are prepared in a manner known per se by mixing the individual components and, if necessary, further processing them in a manner appropriate for the respective type of preparation. Some of these diverse possible preparation forms are described by way of example in the working examples.

[0037] Examples of other hair cosmetic preparations in which Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl) ethanone oxime or salts thereof can be used according to the invention and which may be mentioned are: hair rinses, hair treatments and hair regenerating compositions, which are rinsed out of the hair after a certain time or, depending on the formulation, can also remain on the hair. These preparations comprise inter alia substances from the group of the abovementioned cationic surfactants, which display a reviving and antistatic property on the hair.

[0038] The preparations according to the invention can also be presented in the form of aqueous and aqueous-alcoholic hair lotions, water-wave lotions (hair setting compositions), including those in gel form, and in aerosol form as hair spray, and in the form of hair care and styling creams and gels. The alcohols used are preferably ethanol and isopropanol.

[0039] Examples of resins having a hair-setting and style-holding action, which may be present in a concentration of from 0.5 to 6% by weight, preferably 1 to 3% by weight, in the corresponding preparations (hair setting compositions, hair spray) are: shellac and derivatives, reaction products of rosin with acrylic acid, poly-N-vinylpyrrolidone and alkyl-substituted poly-N-vinylpyrrolidone, poly-N-vinyl-N-alkylacetamide, polyvinyl acetate and partially hydrolyzed polyvinyl acetate, polyvinyl alcohol, alkyl esters of acrylic acid, mixed polymers of vinyl acetate and N-vinyl-N-alkylacetamide, mixed polymers of vinyl acetate and N-vinylpyrrolidone, reaction products of mixed polymers of vinyl acetate and acrylic acid or crotonic acid with organic bases, mixed polymers of vinyl acetate and maleic monoester, mixed polymers of vinyl acetate, vinyl pivalate and crotonic acid, mixed polymers of fatty acid vinyl esters and (meth)acrylic acid, mixed polymers of (meth)acrylic esters and N-vinylpyrrolidone, mixed polymers of acrylic esters and (meth)acrylic acid, alkyl esters of mixed polymers of methyl vinyl ether and maleic anhydride, alkyl esters of mixed polymers of olefins and maleic anhydride, polyvinylacetals and polyvinylbutyrals, dimethylhydantoin-formaldehyde condensates, cyclohexanone-formaldehyde resins, phthalate resins, protein hydrolyzates and protein derivatives, starch derivatives and cellulose derivatives, which may also contain cationic groups, and further film formers containing quaternary groups, such as reaction products of mixed polymers of alkyl (meth)acrylates and dimethylaminoethyl (meth)acrylate with alkylating agents, and also quaternary copolymers of N-vinylpyrrolidone and dialkylaminoalkyl (meth)acrylates.

[0040] All of these preparations are also prepared—as already mentioned in the case of the shampoo—in a manner known per se, with the addition of the active ingredient used according to the invention.

[0041] The antidandruff active ingredient is incorporated into the preparations according to the invention in amounts customarily between about 0.05 and about 10% by weight, based,on the total preparation. Within this range, the concentrations of the specific preparations depend on their intended use. Certain preparation forms such as, for example, concentrates, which are diluted prior to use, can also have considerably higher concentrations.

[0042] For preparations which remain on the hair, such as, for example, hair lotions, hair setting compositions, creams etc., lower concentrations are used, for example of from about 0.01 to about 1% by weight, preferably 0.1 to 0.5% by weight. They are expediently used in higher concentrations for cosmetic preparations which, optionally after dilution, act on hair and scalp for only a short period, such as, for example, shampoos or hair rinses. In these cases, concentrations of from about 0.2 to about 10% by weight, preferably from about 0.5 to about 2% by weight, for example, can be expedient.

[0043] The use according to the invention of said Z-1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)-O-(2,4-dichlorobenzyl) ethanone oxime and salts thereof, in particular oxiconazole nitrate, has numerous advantages over the prior art mentioned.

[0044] The main advantages are:

[0045] low use concentrations

[0046] broad antimicrobial activity spectrum

[0047] low toxicity.

[0048] Oxiconazole nitrate, which is preferably used, is used either in dissolved form, or as a white powder, the particle size preferably being between 50 nm and 1000 nm. Suitable solvents are, for example, ethanol, acetone, n-octanol, polyethylene glycol 400, propylene glycol, butylene glycol, glycerol.

[0049] The examples below illustrate the present invention. The stated amounts are based on weight.
