    [0001] This invention relates to the use of selected fatty compounds as a substitute for silicones in the production of cosmetic and/or pharmaceutical preparations. [0001]
    [0002] 1. Prior Art [0002]
    [0003] Silicones are used in skin and hair cosmetics as additives for influencing feel and luster. Unfortunately, the so-called build-up effect of silicones is a disadvantage. By this is meant that, when silicone-containing products are repeatedly applied to the skin or to the hair, a layer of polymers builds up and is difficult to remove simply by washing. In the case of hair in particular, this layer of polymers is undesirable and can interfere with other treatments, for example waving or dyeing. An overview of the use of silicones in cosmetics was published, for example, by K. Schnurrbusch in [0003] Seifen- Fettepk-Öle-Wachse 100, 173, (1974).
    [0004] Accordingly, the problem addressed by the present invention was to provide silicone substitutes which would not build up in use, but which would still show at least comparable performance properties in regard to feel and luster. [0004]
    [0005] 2. Description of the Invention [0005]
    [0006] The present invention relates to the use of fatty compounds as a silicone substitute in the production of cosmetic and/or pharmaceutical preparations which is distinguished by the fact that oils selected from the group consisting of [0006]
    [0007] (a) dialkyl ethers, [0007]
    [0008] (b) dialkyl cyclohexanes, [0008]
    [0009] (c) Guerbet alcohols, [0009]
    [0010] (d) Guerbet carbonates, [0010]
    [0011] (e) ester oils, [0011]
    [0012] (f) polyol polyhydroxystearates and/or [0012]
    [0013] (g) hydroxycarboxylic acid esters [0013]
    [0014] are used. [0014]
    [0015] It has surprisingly been found that the sensorial evaluation of the selected oils in regard to feel and luster is at least as good as that of silicones without any unwanted build-up effect on skin and hair. [0015]
    [0016] Dialkyl ethers [0016]
    [0017] Dialkyl ethers which form component (a) correspond to formula (I):[0017]
    [0018] in which R[0018] 1 and R2 independently of one another represent a linear or branched alkyl and/or alkenyl radical containing 6 to 22, preferably 8 to 18 and more preferably 12 to 18 carbon atoms. The ethers may have an asymmetrical structure, although they preferably have a symmetrical structure. Typical examples are di-n-octyl ether, di-i-octyl ether and di-n-stearyl ether.
    [0019] Dialkyl cyclohexanes [0019]
    [0020] Dialkyl cyclohexanes which form component (b) correspond to formula (II):[0020]
    [0021] in which R[0021] 3 and R4 independently of one another represent a linear or branched alkyl and/or alkenyl group containing 6 to 22, preferably 8 to 18 and more preferably 12 to 18 carbon atoms and C is a cyclohexyl group. Typical examples are di-n-octyl cyclohexane, di-i-octyl cyclohexane and di-n-stearyl cyclohexane.
    [0022] Guerbet alcohols [0022]
    [0023] Guerbet alcohols which form component (c) are preferably obtained by base-catalyzed self-condensation of linear and/or branched alcohols containing 6 to 22 and preferably 8 to 18 carbon atoms. An overview of Guerbet alcohols was published by A. J. O'Lennick in [0023] Soap Cosm. Chem. Spec. (April) 52 (1987). Typical examples are condensation products of technical fatty alcohol cuts containing 8 to 10 or 16 to 18 carbon atoms.
    [0024] Guerbet carbonates [0024]
    [0025] Guerbet carbonates which form component (d) are normally obtained by complete or partial transesterification of dialkyl carbonates with linear and/or branched alcohols containing 6 to 22, preferably 8 to 18 and more preferably 12 to 18 carbon atoms [cf. DE-A1 40 40 154 (Henkel)]. Typical examples are carbonates which are obtained by transesterification of dimethyl carbonate or diethyl carbonate with fatty alcohols containing 8 to 10 or 12 to 18 carbon atoms, preferably octanol or cetearyl alcohol. [0025]
    [0026] Ester oils [0026]
    [0027] Ester oils which form component (e) are long-chain esters liquid at room temperature which correspond to formula (III):[0027]
    [0028] where R[0028] 5CO is an aliphatic acyl group containing 6 to 22 carbon atoms and R6 is an alkyl and/or alkenyl group containing 12 to 22 carbon atoms. Typical examples are esters of caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, elaeostearic acid, arachic acid, gadoleic acid, behenic acid and erucic acid and technical mixtures thereof with lauryl alcohol, isotridecyl alcohol, myristyl alcohol, cetyl alcohol, palmitoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolyl alcohol, linolenyl alcohol, eleaostearyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol and brassidyl alcohol and technical mixtures thereof. Ester oils which contain at least 24 and preferably at least 30 carbon atoms and one double bond in the fatty acid and fatty alcohol component together are preferred. Typical examples are oleyl erucate, erucyl oleate, behenyl oleate and cetearyl oleate.
    [0029] Polyol polyhydroxystearates [0029]
    [0030] The polyol component of the polyol polyhydroxystearates which form component (f) may be derived from substances which contain at least 2, preferably 3 to 12 and more preferably 3 to 8 hydroxyl groups and 2 to 12 carbon atoms. Typical examples are [0030]
    [0031] glycerol and polyglycerol; [0031]
    [0032] alkylene glycols, such as for example ethylene glycol, diethylene glycol, propylene glycol; [0032]
    [0033] methylol compounds, such as in particular trimethylol ethane, trimethylol propane, trimethylol butane, pentaerythritol and dipentaerythritol; [0033]
    [0034] alkyl oligoglucosides containing 1 to 22, preferably 1 to 8 and more preferably 1 to 4 carbon atoms in the alkyl group, such as for example methyl and butyl glucoside; [0034]
    [0035] sugar alcohols containing 5 to 12 carbon atoms, such as for example sorbitol or mannitol, [0035]
    [0036] sugars containing 5 to 12 carbon atoms, such as for example glucose or sucrose; [0036]
    [0037] amino sugars, such as for example glucamine. [0037]
    [0038] Among the substances which form component (f), reaction products based on polyglycerol are particularly important by virtue of their excellent performance properties. It has proved to be of particular advantage to use selected polyglycerols with the following homolog distribution (the preferred ranges are shown in brackets): [0038]
    [0039] glycerol: 5 to 35 (15 to 30)% by weight [0039]
    [0040] diglycerols: 15 to 40 (20 to 32)% by weight [0040]
    [0041] triglycerols: 10 to 35 (15 to 25)% by weight [0041]
    [0042] tetraglycerols: 5 to 20 ( 8 to 15)% by weight [0042]
    [0043] pentaglycerols: 2 to 10 ( 3 to 8)% by weight [0043]
    [0044] oligoglycerols: to 100% by weight [0044]
    [0045] Hydrocarboxylic acid esters [0045]
    [0046] The last component (g) is selected from esters of hydroxycarboxylic acids containing 3 to 18 and preferably 3 to 12 carbon atoms with aliphatic alcohols containing 1 to 22, preferably 6 to 18 and more preferably 12 to 18 carbon atoms. Typical examples are esters of lactic acid, malic acid, tartaric acid, citric acid, ricinoleic acid and/or 12-hydroxystearic acid with methanol, ethanol, caproic alcohol, caprylic alcohol, 2-ethylhexyl alcohol, capric alcohol, lauryl alcohol, isotridecyl alcohol, myristyl alcohol, cetyl alcohol, palmitoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolyl alcohol, linolenyl alcohol, elaeostearyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol and brassidyl alcohol and technical mixtures thereof. It is preferred to use long-chain hydroxycarboxylic acids, such as ricinoleic acid and hydroxystearic acid, with short-chain alcohols, for example methanol or ethanol, or short-chain hydroxycarboxylic acids, such as lactic acid or citric acid, with long-chain fatty alcohols, such as for example cocofatty alcohol or cetearyl alcohol. [0046]
    [0047] Surfactants [0047]
    [0048] In one preferred embodiment of the invention, the sensorial properties of the fatty compounds can be further improved by mixing with nonionic surfactants, preferably of the alkyl and/or alkenyl oligoglycoside and/or fatty acid-N-alkyl glucamide type. In this embodiment, the fatty compounds and the nonionic surfactants may be used in a ratio by weight of 10:90 to 90:10, preferably in a ratio by weight of 25:75 to 75:25 and more preferably in a ratio by weight of 40:60 to 60:40. [0048]
    [0049] Alkyl and/or alkenyl oligoglycosides [0049]
    [0050] Alkyl and alkenyl oligoglycosides are known nonionic surfactants which correspond to formula (IV):[0050]
    [0051] where R[0051] 7 is an alkyl and/or alkenyl radical 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-A1-0 301 298 and WO 90/03977 are cited as representative of the extensive literature available on this subject.
    [0052] 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. [0052]
    [0053] The index p in general formula (IV) 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. [0053]
    [0054] The alkyl or alkenyl radical R[0054] 7 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's oxosynthesis. Alkyl oligoglucosides having a chain length of C8 to C10 (DP= 1 to 3), which are obtained as first runnings in the separation of technical C8-18 coconut oil fatty alcohol by distillation and which may contain less than 6% by weight of C12 alcohol as an impurity, and also alkyl oligoglucosides based on technical C9/11 oxoalcohols (DP= 1 to 3) are preferred. In addition, the alkyl or alkenyl radical R7 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 C12/14 coconut oil fatty alcohol having a DP of 1 to 3 are preferred.
    [0055] Fatty acid N-alkyl polyhydroxyalkylamides [0055]
    [0056] Fatty acid N-alkyl polyhydroxyalkylamides are nonionic surfactants which correspond to formula (V): [0056]
    [0057] where R[0057] 8CO is an aliphatic acyl radical containing 6 to 22 carbon atoms, R9 is hydrogen, an alkyl or hydroxyalkyl radical containing 1 to 4 carbon atoms and [Z] is a linear or branched polyhydroxyalkyl radical containing 3 to 12 carbon atoms and 3 to 10 hydroxyl groups. The fatty acid N-alkyl polyhydroxyalkylamides are known compounds which may normally be 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. Processes for their production are described in U.S. Pat. No. 1,985,424, in U.S. Pat. No. 2,016,962 and in U.S. Pat. No. 2,703,798 and in International patent application WO 92/06984. An overview of this subject by H. Kelkenberg can be found in Tens. Surf. Det. 25, 8 (1988).
    [0058] The fatty acid N-alkyl polyhydroxyalkylamides are preferably derived from reducing sugars containing 5 or 6 carbon atoms, more particularly from glucose. Accordingly, the preferred fatty acid N-alkyl polyhydroxyalkylamides are fatty acid N-alkyl glucamides which correspond to formula (VI): [0058]
    [0059] Preferred fatty acid N-alkyl polyhydroxyalkylamides are glucamides corresponding to formula (VI) in which R[0059] 9 is hydrogen or an alkyl group and R8CO represents the acyl component of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, arachic acid, gadoleic acid, behenic acid or erucic acid or technical mixtures thereof. Fatty acid N-alkyl glucamides (VI) obtained by reductive amination of glucose with methylamine and subsequent acylation with lauric acid or C12/14 coconut oil fatty acid or a corresponding derivative are particularly preferred. In addition, the polyhydroxyalkylamides may also be derived from maltose and palatinose. Commercial Applications
    [0060] The silicone substitutes are suitable for the production of cosmetic and/or pharmaceutical preparations, preferably skin and hair treatment preparations, for example hair shampoos, hair lotions, foam baths, cremes, lotions or emollients. They may also contain emulsifiers, superfatting agents, stabilizers, waxes, consistency regulators, thickeners, cationic polymers, silicone compounds, biogenic agents, antidandruff agents, film formers, preservatives, hydrotropes, solubilizers, UV filters, dyes and perfumes as further auxiliaries and additives. [0060]
    [0061] Suitable emulsifiers are, for example, nonionic surfactants from at least one of the following groups: [0061]
    [0062] adducts of 2 to 30 moles of ethylene oxide and/or 0 to 5 moles of propylene oxide with linear fatty alcohols containing 8 to 22 carbon atoms, with fatty acids containing 12 to 22 carbon atoms and with alkylphenols containing 8 to 15 carbon atoms in the alkyl group; [0062]
    [0063] C[0063] 12/18 fatty acid monoesters and diesters of adducts of 1 to 30 moles of ethylene oxide with glycerol;

    [0072] The addition products of ethylene oxide and/or propylene oxide with fatty alcohols, fatty acids, alkylphenols, glycerol monoesters and diesters and sorbitan monoesters and diesters of fatty acids or with 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[0072] 12/18 fatty acid monoesters and diesters of adducts of ethylene oxide with glycerol are known as refatting agents for cosmetic formulations from DE-PS 20 24 051.
    [0073] In addition, zwitterionic surfactants may be used as emulsifiers. 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 coco-acylaminopropyl 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 Coco-amidopropyl Betaine is particularly preferred. Ampholytic surfactants are also suitable emulsifiers. Ampholytic surfactants are surface-active compounds which, in addition to a C[0073] 8/18 alkyl or acyl group, contain at least one free amino group and at least one —COOH— or —SO3H— 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-cocoalkylaminopropionate, cocoacylaminoethyl aminopropionate and C12/18 acyl sarcosine. Besides ampholytic emulsifiers, quaternary emulsifiers may also be used, those of the esterquat type, especially methyl-quaternized difatty acid triethanolamine ester salts, being particularly preferred.
    [0074] The superfatting agents used may be such substances as, for example, lanolin and lecithin and polyethoxylated or acylated lanolin and lecithin derivatives, polyol fatty acid esters, monoglycerides and fatty acid alkanolamides, the latter also serving as foam stabilizers. Suitable consistency regulators are, above all, fatty alcohols containing 12 to 22 and preferably 16 to 18 carbon atoms and, in addition, partial glycerides. These substances are preferably used in combination with alkyl oligoglucosides and/or fatty acid-N-methyl glucamides of the same chain length and/or polyglycerol poly-12-hydroxystearates. Suitable thickeners are, for example, polysaccharides, more particularly xanthan gum, guar guar, agar agar, alginates and tyloses, carboxymethyl cellulose and hydroxyethyl cellulose, relatively high molecular weight polyethylene glycol monoesters and diesters of fatty acids, polyacrylates (for example Carbopols® [Goodrich] or Synthalens® [Sigma]), polyacrylamides, polyvinyl alcohol and polyvinyl pyrrolidone, surfactants such as, for example, ethoxylated fatty acid glycerides, esters of fatty acids with polyols such as, for example, pentaerythritol or trimethylol propane, narrow-range fatty alcohol ethoxylates or alkyl oligoglucosides and electrolytes such as sodium chloride and ammonium chloride. [0074]
    [0075] Suitable cationic polymers are, for example, cationic cellulose derivatives such as, for example, the quaternized hydroxyethyl cellulose available under the name of Polymer JR 400® from Amerchol, cationic starch, copolymers of diallyl ammonium salts and acrylamides, quaternized vinyl pyrrolidone/vinyl imidazole polymers such as, for example, Luviquate® (BASF), condensation products of polyglycols and amines, quaternized collagen polypeptides such as, for example, Lauryldimonium Hydroxypropyl Hydrolyzed Collagen (Lamequat®L Grünau), quaternized wheat polypeptides, polyethyleneimine, cationic silicone polymers such as, for example, Amidomethicone, copolymers of adipic acid and dimethyl aminohydroxypropyl diethylenetriamine (Cartaretine®, Sandoz), copolymers of acrylic acid with dimethyl diallyl ammonium chloride (Merquat® 550, Chemviron), polyaminopolyamides as described, for example, in FR-A 225840 and crosslinked water-soluble polymers thereof, cationic chitin derivatives such as, for example, quaternized chitosan, optionally in microcrystalline distribution, condensation products of dihaloalkyls such as, for example, dibromobutane with bis-dialkylamines such as, for example, bis-dimethylamino-1,3-propane, cationic guar gum such as, for example, Jaguar® CBS, Jaguar® C-17, Jaguar® C-16 of Celanese, quaternized ammonium salt polymers such as, for example, Mirapol® A-15, Mirapol® AD-1, Mirapol® AZ-1 of Miranol. [0075]
    [0076] Suitable silicone compounds are, for example, dimethyl polysiloxanes, methyl phenyl polysiloxanes, cyclic silicones and amino-, fatty acid-, alcohol-, polyether-, epoxy-, fluorine- and/or alkyl-modified silicone compounds which may be both liquid and resin-like at room temperature. Typical examples of fats are glycerides while suitable waxes are inter alia beeswax, carnauba wax, candelilla wax, montan wax, paraffin wax or microwaxes, optionally in combination with hydrophilic waxes, for example cetostearyl alcohol, or partial glycerides. The pearlescent waxes used may be, in particular, mono- and difatty acid esters of polyalkylene glycols, partial glycerides or esters of fatty alcohols with polybasic carboxylic acids or hydroxycarboxylic acids. Suitable stabilizers are metal salts of fatty acids such as, for example, magnesium, aluminium and/or zinc stearate. Biogenic agents in the context of the invention are, for example, tocopherol, tocopherol acetate, tocopherol palmitate, ascorbic acid, retinol, bisabolol, allantoin, phytantriol, panthenol, AHA acids, plant extracts and vitamin complexes. Suitable antidandruff agents are climbazol, octopirox and zinc pyrethion. Typical film formers are, for example, chitosan, microcrystalline chitosan, quaternized chitosan, polyvinyl pyrrolidone, vinyl pyrrolidone/vinyl acetate copolymers, polymers of the acrylic acid series, quaternary cellulose derivatives, collagen, hyaluronic acid and salts thereof and similar compounds. In addition, hydrotropes such as, for example, ethanol, isopropyl alcohol or polyols may be used to improve flow behavior. Suitable preservatives are, for example, phenoxyethanol, formaldehyde solution, parabens, pentanediol or sorbic acid. Suitable dyes are any of the substances suitable and approved for cosmetic purposes as listed, for example, in the publication “[0076] Kosmetische Färbemittel” of the Farbstoffkommission der Deutschen Forschungsgemeinschaft, Verlag Chemie, Weinheim, 1984, pages 81 to 106, These dyes are normally used in concentrations of 0.001 to 0.1% by weight, based on the mixture as a whole.
    [0077] The total percentage content of auxiliaries and additives may be from 1 to 50% by weight and is preferably from 5 to 40% by weight, based on the particular formulation. The formulations may be prepared by standard cold or hot processes and are preferably produced by the phase inversion temperature method. [0077] EXAMPLES
    [0078] Various hair shampoos containing the silicone substitutes according to the invention (formulations F1 to F7) or silicone (comparison formulation F8) were evaluated for feel and luster on a scale of 1 (= pleasant soft feel, brilliant luster) to 5 (= hard, dull) by a panel of 20 volunteers in the known half-head test. For qualitatively determining the build-up of the oils on the hair, hair tresses were alternately treated with the test formulations and dried 10 times and then reduced to ashes. A heavy build up of oils is indicated by the symbol (+) in the Table whereas the symbol (−) indicates the absence or substantial absence of oils. The results represent mean values.

    [0079] Hair aftertreatment formulations F9 to F15 and comparison product F16 were tested in the same way. The results are set out in Table 2. [0079] TABLE 2 Hair aftertreatment formulations: feel and luster (quantities in % by weight) Components F9 F10 F11 F12 F13 F14 F15 F16 Cetearylalcohol 3 Cetrimmonium 4 chloride Glyceryl 3 Stearate Dicaprylyl 1 — — — — — — — ether Dicaprylyl — 1 — — — — — — cyclohexane Octyldodecanol — — 1 — — — — — Octyldodecyl — — — 1 — — — — carbonate Oleyl erucate — — — — 1   — — — PEG — — — — — 1 — — hydroxystearate Oleyl lactylate — — — — — —   1 — Dimethicone — — — — — — — 1 NaCl 0.5 Water to 100 Evaluation (half-head test) - Feel   2.5 2   1.5   1.5 2.5 1 2.5 3 - Luster 1   1.5 1 2 2.5 2 2.5   3.5 - Build-up — — — — — — — +
    [0080] The panel tests show that the use of the fatty compounds according to the invention leads to formulations which, when applied to the hair, are judged to be better than the comparison formulations containing silicones and which, at the same time, have the advantage of no build-up effect.
