Description

Hair-setting agent [0001] The present invention reiates to a cosmetic composition, in particuiar a higher-viscosity cosmetic composition for hair setting or for the temporary reshaping of keratinic fibers, in particuiar human hair, which despite the high viscosity has an exceiient appiicabiiity or distributabiiity and moreover a cooiing effect.

[0002] The temporary creation of hairstyies for a ionger time period up to a number of days normaliy requires the use of setting active substances. Hair treatment agents used for a temporary shaping of the hair therefore piay an important roie. Suitabie agents for the temporary reshaping typicaily contain synthetic poiymers and/or waxes as a setting active substance. Agents for supporting the temporary reshaping of hair can be produced, for exampie, as a hair spray, hair wax, hairgei, or hair foam.

[0003] The most important property of an agent for the temporary reshaping of hair, aiso caiied a styiing agent hereinafter, is to give the treated fibers the greatest possibie hoid in the new modeiied shape, i.e., a shape imposed on the hair. This is aiso referred to as a strong hairstyie hoid ora high degree of hoid of the styiing agent. The hairstyie hoid is determined substantiaiiy by the type and amount of the empioyed setting active substances, but the other components of the styiing agent may aiso have an effect.

[0004] in addition to a high degree of hoid, styiing agents must satisfy a wide range of further requirements. These can be divided roughiy into properties on the hair, properties of the particuiar formuiation, e.g., properties of the foam, gei, or sprayed aerosoi, and properties reiated to the handiing of the styiing agent, particuiar importance being attached to the properties on the hair. Mention can be made in particuiar of humidity resistance, iow tackiness (tack), and a baianced conditioning effect. Furthermore, a styiing agent shouid be universaiiy usabie, if possibie, for aii hair types and be gentie to the hair and skin.

[0005] in order to satisfy the different requirements, many synthetic poiymers for use in styiing agents have aiready been deveioped as setting active substances. The poiymers can be divided into cationic, anionic, nonionic, and amphoteric setting poiymers. Aiternativeiy or in addition, waxes are used as setting active substances. The poiymers and/or waxes when used on hair ideaiiy form a poiymer fiim or a fiim that, on the one hand, gives the hairstyie a strong hoid but, on the other, is sufficientiy fiexibie not to break under stress.

[0006] Hair waxes and pastes have gained increasing popuiarity with consumers in recent years, because a fiexibie and reshapeabie hoid can be achieved with products of this kind. These are usuaiiy avaiiabie commerciaiiy in tins or jars or as sticks. Hair waxes and pastes normaiiy contain vegetable, animal, or mineral waxes as the shaping component. For use, these products are often rubbed first in the hands and then distributed on the hair. A good hold of the hair is produced by these hair waxes based on natural raw materials. Nevertheless, the hair waxes on the market do not yet completely satisfy the wishes of users with respect to simple application and easy distribution on the hair. Thus, rubbing on the hands requires either the use of gloves or a subsequent intensive cleaning of the hands to remove product residues with a greasy feel. Furthermore, a very uniform distribution of the product on the hair is only difficult to achieve and requires a great deal of time. Styling agents with a lower viscosity such as hair gels usually have a better distributability. In particular in the case of hair waxes and pastes with a rather high wax proportion, the formed film can become readily brittle and so-called film plaques can form, i.e., residues that detach as the hair moves and give the impression that the user of the particular styling agent has dandruff.

[0007] EP 0868898 A1 discloses wax-containing styling agents with a specific combination of emulsifiers; exemplary embodiments of styling agents are disclosed that contain water and ethanol as the cosmetic carrier, the water content being above 50% by weight.

[0008] An object of the present invention was to provide wax-containing, higher-viscosity cosmetic compositions for hair reshaping and setting such as, for example, hair waxes and hair pastes, which are notable for their good film-forming and/or setting properties, which if possible form no visible residues and in particular can be easily applied to hair and distributed in the hair.

[0009] This was achieved according to the invention by a composition according to claim 1.

[0010] The following is provided by the present invention: 1. A cosmetic composition for the temporary reshaping of keratinic fibers, which contains: (a) at least one wax with a melting point above 40°C in a total amount of 1 to 50% by weight, (b) at least one emulsifier in a total amount of 0.5 to 15% by weight, (c) at least one film-forming polymer in a total amount of 1 to 20% by weight, (d) ethanol in a total amount of 0.5 to 50% by weight, and (e) water in a total amount of 1 to 50% by weight, wherein the weight data in each case refers to the total weight of the cosmetic composition. 2.

(b) a total amount of 1 to 10% by weight, preferably 2 to 5% by weight, of the at least one emulsifier, (c) a total amount of 2 to 15% by weight, preferably 3 to 10% by weight, of the at least one film-forming polymer, (d) ethanol in a total amount of 20 to 50% by weight, preferably 25 to 40% by weight, and (e) water in a total amount of 5 to 40% by weight, preferably 10 to 40% by weight. 3. The cosmetic composition according to point 1 or 2, wherein the at least one wax (a) is selected from vegetable waxes, microcrystalline wax, and mixtures thereof. 4. The cosmetic composition according to any one of the preceding points, wherein the at least one wax (a) is selected from carnauba wax, (INCI: Copernicia Cerifera Cera), Myrica Cerifera Fruit Wax (INCI), Rhus Verniciflua Peel Cera (INCI), beeswax (INCI: Beeswax Cera Alba), lanolin (INCI: Lanolin), microcrystalline wax, and in particular mixtures thereof, preferably of carnauba wax, (INCI: Copernicia Cerifera Cera), Myrica Cerifera Fruit Wax (INCI), Rhus Verniciflua Peel Cera (INCI), microcrystalline wax, and in particular mixtures thereof. 5. The cosmetic composition according to any one of the preceding points, wherein 50% by weight or more of the total amount of wax, preferably 70% by weight to 90% by weight of the total wax amount, has a melting point in the range of 45 to 60°C. 6. The cosmetic composition according to point 5, wherein the rest of the wax amount is formed by waxes with a melting point of 80°C or higher, preferably 80 to 90°C. 7. The cosmetic composition according to any one of the preceding points, wherein the at least one emulsifier (b) is selected from nonionic emulsifiers, in particular from adducts of 2 to 50 mol of ethylene oxide to linear fatty alcohols having 12 to 18 carbon atoms, adducts of 2 to 50 mol of ethylene oxide and 1 to 5 mol of propylene oxide to linear fatty alcohols having 12 to 18 carbon atoms, and mixtures thereof. 8. The cosmetic composition according to any one of the preceding points, wherein the at least one film-forming polymer is at least one vinylpyrrolidone/vinyl acetate copolymer, the ratio of vinylpyrrolidone (VP) to vinyl acetate (VA) preferably being 50:70 to 30:50, more preferably about 60:40. 9. The cosmetic composition according to any one of the preceding points, wherein the composition furthermore contains at least one care component. 10. The cosmetic composition according to any one of the preceding points, wherein the composition is present as a hair wax, paste, lotion, or clay. 11. The cosmetic composition according to point 10, wherein the cosmetic composition is produced as a stick. 12. A cosmetic, nontherapeutic use of a cosmetic composition according to any one of points 1 to 11 for the temporary reshaping of keratinic fibers. 13. A method for the temporary reshaping of keratinic fibers, in particular human hair, in which the cosmetic composition according to any one of points 1 to 11 is applied to keratinic fibers. 14. The method according to point 13, wherein the cosmetic composition is produced as a stick and wherein the application of the cosmetic composition to the hair occurs directly from the stick to the hair.

[0011] The present invention relates to higher-viscosity styling agents such as hair waxes, pastes, or lotions, where ‘higher-viscosity’ is taken to mean that the styling agents retain their form and do not flow at room temperature (about 25°C), but are usually ductile.

[0012] It was determined surprisingly within the scope of the present invention that by including ethanol in specific amounts, in combination with other essential components in specific amounts, excellent distribution of the higher-viscosity styling agents in the hair can be achieved. Furthermore, the styling agents of the invention have no visible residues during use on hair.

[0013] The combination of ingredients according to the invention with the necessary, preferably high ethanol content in particular enables the production of styling agents that change their texture upon contact with the hands such that the initially wax- or paste-like styling agents become softer or melt in the hands and become liquid. This property of the styling agents of the invention can also be called a hybrid-like texture.

[0014] It was found surprisingly, furthermore, that a cooling effect occurs upon rubbing of the styling agents of the invention between the hands. Said cooling effect is experienced upon rubbing between the hands and is regarded as refreshing particularly at warmer temperatures. The cooling effect is optionally also experienced immediately after application to the head, however, which imparts a feeling of freshness.

[0015] Other usually required properties of styling products such as long-lasting hold, stiffness, and low tackiness are retained in this case.

[0016] The term keratinic fibers according to the invention covers peits, wooi, and feathers but in particuiar human hair.

[0017] The styiing agent of the invention contains as component (a) at ieast one naturai or synthetic wax that has a meiting point above 40°C. The styiing agent of the invention contains the at ieast one wax in a totai amount of 1 to 50% by weight, preferably 5 to 40% by weight, more preferably 10 to 30% by weight, likewise preferably 10 to 20% by weight, based on the total weight of the styling agent.

[0018] Used as natural or synthetic waxes according to the invention can be solid paraffins or isoparaffins, vegetable waxes such as candelilla wax, carnauba wax, esparto grass wax, Japan wax, cork wax, sugar cane wax, ouricury wax, montan wax, sunflower wax, fruit waxes, and animal waxes such as, e.g., beeswax and other insect waxes, spermaceti wax, shellac wax, wool wax, and uropygial fat, furthermore mineral waxes such as, e.g., ceresin and ozokerite, or petrochemical waxes such as, e.g., petroleum jelly, paraffin waxes, polyethylene or polypropylene microwaxes, and polyethylene glycol waxes. It can be advantageous to use hydrogenated or hardened waxes. Furthermore, chemically modified waxes can be used, in particular hard waxes, e.g., montan ester waxes, sasol waxes, and hydrogenated jojoba waxes.

[0019] Suitable furthermore are the triglycerides of saturated and optionally hydroxylated C16-C30 fatty acids such as, e.g., hydrogenated triglyceride fats (hydrogenated palm oil, hydrogenated coconut oil, hydrogenated castor oil), glyceryl tribehenate or glyceryl tri-12-hydroxystearate, furthermore synthetic full esters of fatty acids and glycol (e.g., Syncrowachs®), or polyols having 2-6 C atoms, fatty acid monoalkanolamides with a C12-C22 acyl group and a C2-C4 alkanol group, esters of saturated and/or unsaturated, branched and/or unbranched alkane carboxylic acids with a chain length of 1 to 80 C atoms and saturated and/or unsaturated, branched and/or unbranched alcohols with a chain length of 1 to 80 C atoms, including, e.g., synthetic fatty acid/fatty alcohol esters such as stearyl stearate or cetyl palmitate, esters of aromatic carboxylic acids, dicarboxylic acids or hydroxycarboxylic acids (e.g., 12-hydroxystearic acid) and saturated and/or unsaturated, branched and/or unbranched alcohols with a chain length of 1 to 80 C atoms, lactides of long-chain hydroxycarboxylic acids, and full esters of fatty alcohols and di- and tricarboxylic acids, e.g., dicetylsuccinate or dicetyl/stearyl adipate, as well as mixtures of said substances.

[0020] The wax components can also be selected from the group of esters of saturated, unbranched alkane carboxylic acids with a chain length of 14 to 44 C atoms and saturated, unbranched alcohols with a chain length of 14 to 44 C atoms, provided the wax component or the totality of wax components are solid at room temperature. The wax components can be selected, for example, from the group of C16-C36 alkyl stearates, C10-C40 alkyl stearates, C2-C40 alkyl isostearates, C20-C40 dialkyl esters of dimeric acids, C18-C38 alkyl hydroxystearoyl stearates, and C20-C40 alkyl erucates; further C30-C50 alkyl beeswax and cetearyl behenate can be used. Silicone waxes, for example, stearyl trimethylsilane/stearyl alcohol are optionally also advantageous. Preferred wax components are the esters of saturated, monohydric C20-C60 alcohols and saturated C8-C30 monocarboxylic acids, a C20-C40 alkyl stearate being preferred in particular that is available under the name Kesterwachs® K82H from the company Koster Keunen Inc.

[0021] Natural, chemically modified, and synthetic waxes can be used alone or in combination.

The teaching of the invention therefore also encompasses the combined use of multiple waxes. Furthermore, a number of wax mixtures, optionally mixed with further additives, are also commercially available. Those having the designations "Spezialwachs 7686 OE" (a mixture of cetyl palmitate, beeswax, microcrystalline wax, and polyethylene with a melting range of 73-75°C; manufacturer: Kahl & Co), Polywax® GP 200 (a mixture of stearyl alcohol and polyethylene glycol stearate with a melting point of 47-51 °C; manufacturer: Croda), and "Weichceresin® FL 400" (a vaseline/vaseline oil/wax mixture with a melting point of 50-54°C; manufacturer: Parafluid Mineralolgesellschaft) are examples of mixtures used according to the invention.

[0022] Preferably, wax (a) is selected from carnauba wax (INCI: Copernicia Cerifera Cera), Myrica Cerifera Fruit Wax (INCI), Rhus Verniciflua Peel Cera (INCI), beeswax (INCI: Beeswax Cera Alba), lanolin (INCI: Lanolin), microcrystalline wax, as well as in particular mixtures thereof.

[0023] Particularly preferably, wax (a) is selected from vegetable waxes, in particular carnauba wax (INCI: Copernicia Cerifera Cera), Myrica Cerifera Fruit Wax (INCI), and/or Rhus Verniciflua Peel Cera (INCI), and microcrystalline wax, as well as in particular mixtures thereof.

[0024] The wax or wax components should be solid at 25°C and should melt according to the invention in the range of >40°C. In preferred embodiments of the invention, 50% by weight or more of the total wax amount (a), preferably 70% by weight to 90% by weight of the total wax amount (a), has a melting point in the range of 45 to 60°C. It is preferred further that the remaining amount of wax is formed by waxes with a melting point of 80°C or higher, preferably 80 to 90°C.

[0025] The composition of the invention contains at least one emulsifier as a further essential component (b). Anionic, cationic, nonionic, and ampholytic surface-active compounds suitable for use on the human body may be used in principle as emulsifiers. The ampholytic surface-active compounds comprise zwitterionic surface-active compounds and ampholytes. Nonionic emulsifiers are preferred.

[0026] In particular, adducts of ethylene oxide to linear fatty alcohols, to fatty acids, to fatty acid alkanolamides, to fatty acid monoglycerides, to sorbitan fatty acid monoglycerides, to fatty acid glycerides, to methylglucoside monofatty acid esters, to polydimethylsiloxanes, and mixtures thereof can be used as nonionic emulsifiers.

Examples of particularly preferred nonionic surfactants are compounds with the INCI names: Steareth-2, Steareth-21, or PPG-5-Ceteth-20, and in particular combinations thereof.

[0028] The styling agent of the invention contains the at least one emulsifier in a total amount of 0.5 to 15% by weight, preferably 1 to 10% by weight, more preferably 2 to 5% by weight, based on the total weight of the styling agent.

[0029] The cosmetic composition (styling agent) of the invention contains furthermore as essential component (c) at least one film-forming polymer, which is different from wax component (a). Examples are cationic, anionic, nonionic, or amphoteric polymers. The styling agent of the invention contains the at least one film-forming polymer (c) in a total amount of 1 to 20% by weight, preferably 2 to 15% by weight, more preferably 3 to 10% by weight, based on the total weight of the styling agent.

[0031] Siloxanes are suitable furthermore as film-forming polymers. These siloxanes can be both water-soluble and water-insoluble. Both volatile and nonvolatile siloxanes are suitable, nonvolatile siloxanes being understood to be compounds whose boiling point at normal pressure is above 200°C. Preferred siloxanes are polydialkylsiloxanes such as, for example, polydimethylsiloxane, polyalkylarylsiloxanes such as, for example, polyphenylmethylsiloxane, ethoxylated polydialkylsiloxanes, and polydialkylsiloxanes that contain amine and/or hydroxy groups.

[0032] Glycosidically substituted silicones may also be used.

[0033] Homopolyacrylic acid (INCI: Carbomer), which is commercially available under the name Carbopol® as different types, is suitable as a film-forming polymer.

[0034] The film-forming polymer is preferably selected from nonionic polymers, in particular vinylpyrrolidone/vinyl ester copolymers. Particularly preferred is a vinylpyrrolidone/vinyl acetate copolymer, the ratio of vinylpyrrolidone (VP) to vinyl acetate (VA) being preferably 50:70 to 30:50, more preferably about 60:40. These are available, for example, under the trademark Luviskol (BASF), e.g., Luviskol VA 64 and Luviskol VA 73.

[0035] The composition of the invention contains a combination of ethanol and water as a cosmetic carrier. The cosmetic composition of the present invention therefore contains ethanol as an essential component. The ethanol content of the composition of the invention is 0.5 to 50% by weight, preferably 20 to 50% by weight, likewise preferably 25 to 40% by weight. It was determined surprisingly that upon inclusion of ethanol, preferably in higher amounts, a melting effect of wax-containing styling agents can be achieved, so that waxes with a low melting point below 40°C need not be used. An excellent applicability of the composition of the invention is achieved thereby. The melting effect is evident in that the initially wax- or paste-like styling agents become softer or melt in the hands or become liquid, which improves the applicability. The melting effect can be so pronounced, however, particularly at the preferred higher ethanol contents, that application of the styling agent of the invention is possible without contact with the hands. The cosmetic composition can therefore be produced as a stick, which enables application directly to the hair, without contact with the hands. "Melting" can then occur even with light pressure on the hair.

[0036] At the same time, a cooling effect is also achieved by the ethanol content. This cooling effect can occur when the styling agents of the invention are rubbed between the hands, which is regarded as refreshing particularly at warmer temperatures. The cooling effect, however, is experienced optionally also immediately after application to the head, which imparts a feeling of freshness to the head.

[0037] The water content of the cosmetic composition of the invention is 1 to 50% by weight, preferably 5 to 40% by weight, more preferably 10 to 40% by weight.

[0038] In order to intensify the above-described cooling effect of the cosmetic compositions of the invention, furthermore cosmetically acceptable components can be added that have a cooling effect, for example, by evaporation, such as isopropanol, or have a cooling action by acting on receptors in the skin, for example, menthol and menthol derivatives. An example of a compound that causes a cold sensation in skin receptors is menthyl (Ethylamido Oxalate (INCI)), which is available commercially, for example, under the name Frescolat® X-Cool (Symrise).

[0039] Care substances in particular such as, for example, oils, can be cited as additional suitable aids and additives.

[0040] Oils suitable according to the invention are selected from esters of linear or branched, saturated or unsaturated fatty alcohols having 2 to 30 carbon atoms with linear or branched, saturated or unsaturated fatty acids having 2 to 30 carbon atoms, which can be hydroxylated. These include cetyl-2-ethylhexanoate, 2-hexyldecyl stearate (e.g., Eutanol® G 16 S), 2-hexyldecyl laurate, isodecyl neopentanoate, isononyl isononanoate, 2-ethylhexyl palmitate (e.g., Cegesoft® C 24), and 2-ethylhexyl stearate (e.g., Cetiol® 868). Also preferred are isopropyl myristate, isopropyl palmitate, isopropyl stearate, isopropyl isostearate, isopropyl oleate, isooctyl stearate, isononyl stearate, isocetyl stearate, isononyl isononanoate, isotridecyl isononanoate, cetearyl isononanoate, 2-ethylhexyl laurate, 2-ethylhexyl isostearate, 2-ethylhexyl cocoate, 2-octyldodecyl palmitate, butyloctanoic acid-2-butyl octanoate, diisotridecyl acetate, n-butyl stearate, n-hexyl laurate, n-decyl oleate, oleyl oleate, oleyl erucate, erucyl oleate, erucyl erucate, ethylene glycol dioleate, and ethylene glycol dipalmitate. Cetyl-2-ethylhexanoate is particularly preferred.

[0041] Further oils preferred according to the invention are selected from natural and synthetic hydrocarbons, particularly preferably from mineral oils, paraffin oils, C18-C30 isoparaffins, in particular isoeicosane, polyisobutenes and polydecenes, which are obtainable, for example, under the name Emery® 3004, 3006, 3010 or under the name Ethylflo® from Albemarle or Nexbase® 2004G from Nestle, furthermore selected from Cs-Cie isoparaffins, in particular from isodecane, isododecane, isotetradecane, and isohexadecane, as well as mixtures thereof, and 1,3-di-(2-ethylhexyl)cyclohexane (obtainable, e.g., under the trade name Cetiol® S of BASF).

[0042] Further oils preferred according to the invention are selected from the benzoic acid esters of linear or branched C8-C22 alkanols. Particularly preferred are benzoic acid-Ci2-Ci5-alkyl esters, e.g.. obtainable as the commercial product Finsolv® TN, benzoic acid isostearyl esters, e.g., obtainable as the commercial product Finsolv® SB, ethylhexyl benzoate, e.g., obtainable as the commercial product Finsolv® EB, and benzoic acid octyidodecyl esters, e.g., obtainable as the commercial product Finsolv® BOD.

[0043] Further oils preferred according to the invention are selected from fatty alcohols having 6 to 30 carbon atoms, which are unsaturated or branched and saturated or branched and unsaturated.
