This application claims priority to German Patent Application No. 10 2016 225 472.3, filed Dec. 12, 2016, which is incorporated herein by reference in its entirety.
The present disclosure relates to a cosmetic preparation for hair fixing or for temporarily deforming keratinous fibers, in particular human hair, wherein the composition contains a combination of two specific copolymers.
The temporary design of hairstyles for a longer period of time of up to several days normally employs the use of firming active ingredients. Therefore, hair treatment agents that temporarily shape the hair play a role. Corresponding agents for temporary deformation normally contain synthetic polymers and/or waxes as a firming active ingredient. Agents aiding the temporary deformation of keratinous fibers can be packaged, for instance, as hairspray, hair wax, hair gel or mousse.
One feature of an agent for temporary deformation of hair, also referred to hereinafter as a styling agent, includes giving the treated fibers in the newly modeled shape—i.e. a shape impressed on the hair—the strongest possible hold. This is also referred to as a strong hairstyle hold or a high degree of hold of the styling agent. The hairstyle hold is essentially determined by the type and amount of firming active ingredients used, wherein the other components of the styling agent can also have an influence.
In addition to a high degree of hold, the styling agent must fulfill a series of additional requirements. They can be roughly divided in to characteristics on the hair, characteristics of the respective formulation, e.g. characteristics of the foam, gel or sprayed aerosol, and characteristics relating to the handling of the styling agent. This includes, in for example, moisture resistance, low stickiness (tack) and a balanced conditioning effect. Furthermore, a styling agent may be universally applicable for all hair types, insofar as possible, and mild to the hair and skin.
In order to satisfy some features, a multitude of synthetic polymers was developed as firming active ingredients, which can be used in styling agents. The polymers can be divided into cationic, anionic, nonionic and amphoteric firming polymers. For example, the polymers may create a polymer film when used on the hair, which lends the hairstyle a strong hold and is sufficiently flexible in order to not break under stress. If the polymer film is too brittle, so-called flakes form, i.e. residue, which detach during movement of the hair and give the impression that the user of the corresponding styling agent has dandruff. Similar problems arise when waxes are used as a firming active ingredient in the styling agent. If the styling agent is a gel or a paste, the polymers nay also have thickening properties.
Cationic polymers that are used in hair fixing products are copolymers with two or more structural units. Specific copolymers of this type, based on the monomers N-vinylimidazole and N-vinyllactam with the INCI designations POLYQUATERNIUM-44, POLYQUATERNIUM-46 and POLYQUATERNIUM-68 and their use in agents for temporary hair deformation are described in the German application DE 10 2013 226 806 A1. Such copolymers are available under the trade names Luviquat® UltraCare, Luviquat® Hold and Luviquat® Supreme.
Additional anionic polymers that are used in hair fixing products are crosslinked anionic amphiphilic polymers that contain a (meth)acrylic acid unit and a (meth)acrylic acid oxyalkylene alkyl ester unit. Such polymers are described in the international patent application WO 2016/142013 A1 and are commercially available, for example, under the name BALANCE® RTF (INCI: acrylates/ceteareth-20 methacrylate crosspolymer). In styling products, this polymer essentially has the task of a thickening agent and film former.
The present disclosure addresses the problem of providing additional polymer combinations, which is exemplified by good film-forming and/or fixing properties, has a very high degree of hold without the need to dispense with flexibility and good moisture resistance—such as sweat and water resistance— and is also suitable for production of stable viscous and stable transparent cosmetic preparations. For example, currently available styling agents can be improved, because a good combination of stiffness and long-term hold (high humidity curl retention) is not always sufficiently available. Therefore, the present disclosure addresses the problem of preparing such styling agents that provide the aforementioned properties, for example with regard to good stiffness and a good, long-term hold.
As contemplated herein, this was achieved by employing a combination of two specific anionic copolymers.
The present application provides:
from about 0.1 to about 10 wt. % of the anionic copolymer (b).
The following detailed description is merely exemplary in nature and is not intended to limit the disclosure or the application and uses of the subject matter as described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
Surprisingly, it was discovered in the context of the present disclosure that a combination of two known components that are already used in styling products can achieve an improved hold of styling products. Other conventionally required properties of styling products, such as moisture resistance, stiffness and low stickiness are retained in the process. Such a good combination of properties was not to be expected even when the individual components are known and was surprising. Experiments showed that the combination of the two components produced a strong overadditive, in other words a synergistic effect with regard to the hold, which is manifested in the 3PB test (3-Point Bending test) and in the HHRC-Test (High Humidity Curl Retention test).
As contemplated herein, the term keratinous fibers comprises fur, wool and feathers, for example human hair.

The crosslinked acrylate copolymer (b) is amphiphile based on the integral structural units. A person skilled in the art understands “amphiphile” to generally mean that one and the same molecule comprises hydrophilic structural elements (e.g. of formula (B-I)) and lipophilic structural elements (e.g. of formula (B-II)).
In the above formulae and all formulae below, a chemical bond bearing the symbol * denotes a free valence of the corresponding structural fragment. Ammonium ion and cationic organic compounds having a quaternized nitrogen atom are suitable as physiologically compatible cations M+ for compensation of the negative charge of the amphiphilic, anionic polymer metal cations of the physiologically compatible metals from the groups Ia, Ib, IIa, IIb, IIIb, VIa or VIII of the period system of elements. Cationic organic compounds having a quaternized nitrogen atom are, for example, produced by employing protonation of primary, secondary or tertiary organic amines with an acid, or by employing permanent quaternization of said organic amines. Examples of such cationic organic ammonium compounds are 2-ammonioethanol and 2-trimethylammonioethanol.
The terms “crosslinked” and “crosslinking” in the context of the present disclosure are understood to mean the linking of polymer chains with each other by employing covalent chemical bonding with formation of a network. This covalent linking of polymer chains may take place by employing direct covalent bonding or by employing a molecular fragment bridging the polymer chain. The molecular fragment connects to the polymer chains bridged by the molecular fragment by employing covalent chemical bonding in each case.
The crosslinking of the crosslinked copolymers (b) can be produced using at least one crosslinked monomer. In the process, the crosslinked monomers may be selected from at least one compound of the group of polyunsaturated aromatic monomers (such as divinylbenzene, divinylnaphthalene, trivinylbenzene),polyunsaturated alicyclic monomers (such as1,2,4-trivinylcyclohexane), di-functional esters of phthalic acid (such as diallyl phthalate), polyunsaturated aliphatic monomers (such asdienes, trienes, tetraenes such as isoprene, 1,3-butadiene, 1,5-hexadiene,1,5,9-decatriene, 1,9-decadiene, 1,5-heptadiene), polyalkenyl ethers (such as triallyl pentaerythritol, diallyl pentaerythritol, diallyl sucrose, octaallyl sucrose, trimethylolpropane diallyl ether), polyunsaturated esters of polyalcohols or polyacids (such as 1,6-hexanediol di(meth)acrylate, tetramethylene tri(meth)acrylate, allyl acrylate, diallyl itaconate, diallyl fumarate, diallyl maleate, diallyl maleate, trimethylolpropane tri(meth)acrylate, trimethylolpropane di(meth)acrylate, polyethylene glycol di(meth)acrylate), alkylene bisacrylamides (such as methylenebisacrylamide, propylene bisacrylamide) hydroxy- and carboxy derivatives of methylene bisacrylamide (such as N,N′-bis-methylol methylene-bis-acrylamide), polyethylene glycol di(meth) acrylates (such as ethylene glycol di(meth)acrylate, diethyleneglycoldi (meth)acrylate, triethylene glycoldi(meth)acrylate), polyunsaturated silanes (such as dimethylvinylsilane, methyltrivinylsilane, allyl dimethylvinylsilane, diallyl dimethylsilane, tetravinylsilane), n-methylolacrylamide; n-alkoxy(meth) acrylamide, wherein the alkoxy group is a (C1 to C18)-alkoxy group, unsaturated hydrolyzable silanes (such as triethoxyvinylsilane, tris-isopropoxy-vinylsilane, 3-triethoxysilyl-propylmethacrylate), hydrolyzable silanes (such as ethyltriethoxysilane, ethyltrimethoxysilane), epoxy-substituted hydrolyzable silanes (such as 2-(3,4-epoxycyclohexypethyltriethoxysilane, 3-glycidoxypropyltrimethyoxysilane) polyisocyanates (such as 1,4-diisocyanatobutane, 1,6-diisocyanatohexane, 1,4-phenylenediamine diisocyanate, 4,4′-oxybis (phenylisocyanate), unsaturated epoxides (such as glycidylmethacrylates, allyl glycidyl ether), polyepoxides (such asdiglycidyl ether, 1,2,5,6-diepoxy hexane, ethylene glycol diglycidyl ether), ethoxylated polyols (such as diols, triols and diphenols, each ethoxylated with from about 2 to about 100 moles of ethylene oxide per mole of hydroxyl groups and terminated with a polymerizable unsaturated group, such as, vinyl ether, allyl ether, acrylate ester, methacrylate ester; examples comprise bisphenol A ethoxylated di(Meth)acrylate, bisphenol F ethoxylated di(meth)acrylate, ethoxylated trimethylolpropane tri(meth)acrylates, acrylate and methacrylate esters of polyols having at least two acrylate ester or methacrylate ester-functionalities (such as trimethylolpropane triacrylate (TMPTA), trimethylolpropane ethoxylated (15) triacrylate (TMPEO15TA), trimethylolpropane dimethacrylate, triethyleneglycoldimethacrylate (TEGDMA), with about 30 mol of ethylene oxide ethoxylated bis-phenol A-dimethacrylate (EOBDMA)).
As contemplated herein, the copolymer (b) can be composed of additional structure units. In one embodiment, the copolymer (b) includes at least about 30 wt. %, such as about 40 to about 98 wt. % and for example at least about 50 to about 95 wt. % of monomers (B-I) and (B-II). However, in an exemplary embodiment of the present disclosure, the copolymer (b) only includes units (B-I) and (B-II) and units to be crosslinked, i.e. it is composed of these structural units.
The at least one unit (B-I) is a (meth)acrylic acid unit and, as contemplated herein, can be a methacrylic acid unit and/or acrylic acid unit. In some embodiments, the unit (B-I) is a methacrylic acid unit (R′ in formula (B-I) denotes a methyl group). Corresponding acrylic polymers (b) have been found to be useful for cosmetic applications.
In some embodiments, x in the structural unit (B-II) of the crosslinked acrylate copolymer (b) denotes an integer from about 10 to about 24, such as from about 16 to about 22, for example about 20.
In some embodiments, R3 in unit (B-II) of the crosslinked acrylate copolymer (b) denotes a (C12-C20)-alkyl group, such as a (C14-C20)-alkyl group, also for example a (C16-C18)-alkyl group. The alkyl group in this context may be linear, but can also be branched. R3 denotes, for example, a combination of linear C16- and C18-alkyl groups, i.e. stearyl- and cetyl groups (INCI: ceteareth). Corresponding acrylic polymers (b) have been found to be useful for cosmetic applications.
In some embodiments, contained crosslinked acrylate copolymer (b) is a crosslinked acrylate copolymer with the INCI designation acrylates-ceteareth-20 methacrylate crosspolymer. In some embodiments, the crosslinked acrylate copolymer (b) is a crosslinked acrylate copolymer available under the trade name BALANCE® RCF (AkzoNobel). The latter is an approximately 30 wt. % dispersion in water.
Additional crosslinked acrylate copolymers (b) are identified by the INCI designation acrylates/steareth-20 methacrylate crosspolymer. In such crosslinked acrylate copolymers, the at least one unit (al) is a (meth)acrylic acid unit and, as contemplated herein, can be a methacrylic acid unit and/or acrylic acid unit. They have about 20 units of ethylene oxide and are etherified with stearyl alcohol. One such polymer, for example, is available under the trade name Aculyn® 88 (Rohm & Haas). In the commercially available form, this has a solids content of approximately 28 to 33 wt. % and a pH value of from about 3.3 to about 4.3.
Compared to alternative cosmetic agents, the cosmetic preparations as contemplated herein are exemplified by an improved long-term hold, in addition to the aforementioned advantages. A weight ratio of polymers a) and b) in the cosmetic preparations of from about 5:1 to about 1:5, such as from about 3:1 to about 1:3 and for example from about 2:1 to about 1:2 has been found to be useful for the cosmetic properties of the inventive agent.
In one embodiment of the present disclosure, the cosmetic preparation contains the copolymer commercially available under the name Luviquat® Supreme as the copolymer (a) and the copolymer commercially available under the name BALANCE® RCF as the crosslinked acrylate copolymer (b). Particularly good results with regard to a combination of stiffness and long-term hold were achieved with this combination. This polymer combination is useful for styling products in gel form.
Additional properties generally observed by styling products, such as moisture resistance and low stickiness, are also provided with this combination, for example when packaged as hair gel.
The copolymers (a) and (b) may be used in partially neutralized or neutralized form in the cosmetic preparation. At least one alkanolamine may be used for neutralization. The alkanolamines used as an alkalization agent in the context of the present disclosure may be selected from primary amines with a C2-C6-alkyl base body having at least one hydroxyl group. It may be that alkanolamines are selected from the group comprising 2-aminoethan-1-ol (monoethanolamine), 3 -(2-hydroxyethyl)-amine (triethanolamine), 3 -aminopropan-1-ol, 4-amino-butan-1-ol, 5 -aminopentan-1-ol, 1-aminopropan-2-ol, 1-aminobutan-2-ol, 1-aminopentan-2-ol, 1-aminopentan-3-ol, 1-aminopentan-4-ol, 3-amino-2-methylpropan-1-ol, 1-amino-2-methylpropan-2-ol, 3-aminopropan-1,2-diol, 2-amino-2-methylpropan-1,3-diol. As contemplated herein, it is most preferable that alkanolamines are selected from the group of 2-aminoethan-1-ol, 2-amino-2-methylpropan-1-ol and 2-amino-2-methyl-propan-1,3-diol. In this context, 2-amino-2-methylpropanol has been found to be suitable as a neutralization agent. Therefore, some agents as contemplated herein contain 2-amino-2-methylpropanol. The 2-amino-2-methylpropanol may be used in the agents in a quantity which does not exceed the quantity required for neutralization of copolymers (a) and (b). For example, the quantities of 2-amino-2-methylpropanol used in the preparations are from about 80 to about 100%, such as from about 90 to about 100% and for example from about 95 to about 100% of the quantity required for complete neutralization of copolymers (a) and (B). In one embodiment, the proportion by weight of the 2-amino-2-methylpropanol to the total weight of the cosmetic agent is from about 0.05 to about 7.0 wt. %, such as from about 0.1 to about 5.0 wt. % and for example from about 0.1 to about 3.0 wt. %.
In summary, an exemplary cosmetic preparation for temporary deformation of keratinous fibers contains, relative to its total weight:
The cosmetic preparation according to the present disclosure may contain one or more additional component(s) which differ(s) from the copolymers (a) and (b) and aid the thickening agent or the gel formation or film formation. Examples are cationic, anionic, nonionic or amphoteric polymers. The proportion by weight of these additional components to the total weight of the cosmetic preparation can be comparatively low due to the present of components (a) and (B) and, for example, be from about 0.02 to about 3 wt. %, such as from about 0.05 to about 1.5 wt. % and for example from about 0.2 to about 0.8 wt. %.

The carbomer may be contained in a proportion of from about 0.02 to about 3 wt. %, such as from about 0.05 to about 1.5 wt. % and for example from about 0.2 to about 0.8 wt. %, relative to the total weight of the cosmetic preparation.
To further improve the cosmetic effect, some preparations contain, in addition to the copolymers (a) and (b) and an optionally added thickening agent or gel former, a film-forming polymer (c) differing from these ingredient, for example an anionic or nonionic polymer (c).
Examples of nonionic polymers are:
Due to their cosmetic effect in combination with the copolymers a) and b), as contemplated herein, suitably used film-forming polymers are polyvinylpyrrolidones (INCI designation: PVP) and vinylpyrrolidone/vinylacetate copolymers (INCI designation VP/VA copolymer). The proportion by weight of these polymers may be limited to quantities between about 1.0 and about 10 wt. %. Some cosmetic preparations as contemplated herein, therefore, are exemplified in that they contain an additional from about 1.0 to about 10 wt. % of polyvinylpyrrolidone and/or vinylpyrrolidone/vinylacetate-copolymer, such as polyvinylpyrrolidone, relative to their total weight. Exemplary cosmetic agents have a proportion by weight of from about 2.0 to about 8.5 wt. %, such as from about 3.0 to about 7.0 wt. % of polyvinylpyrrolidone and/or vinylpyrrolidone/vinylacetate-copolymers c), relative to the total weight of the cosmetic agent.
The cosmetic preparation can contain additional conventional ingredients of styling products. Additional care substances, in particular, can be mentioned as additional suitable auxiliary substances and additives.
As the nourishing agent, the agent can contain at least one protein hydrolysate and/or a derivate thereof, for example. Protein hydrolysates are product mixtures obtained through the acidically, basically or enzymatically catalyzed decomposition of proteins. As contemplated herein, the expression protein hydrolysates also includes total hydrolysates, as well as individual amino acids and the derivatives thereof, as well as mixtures of various amino acids. The molecular weight of the protein hydrolysates usable as contemplated herein is between about 75, the molecular weight for glycine, and about 200,000, such as from about 75 to about 50,000 and for example from about 75 to about 20,000 Dalton.
The agent as contemplated herein can also contain, as a nourishing agent a vitamin, a provitamin, a vitamin precursor and/or a derivative thereof As contemplated herein, such vitamins, provitamins and vitamin precursors are usually assigned to the groups A, B, C, E, F and H.
Similar to the addition of glycerine and/or propylene glycol, the addition of panthenol increases the flexibility of the polymer film formed using the inventive agent.
The agent as contemplated herein can also contain, as a nourishing agent, a plant extract, as well as mono- and/or oligosaccharides and/or lipids.
Furthermore, oil bodies are suitable as care substances. The natural and synthetic cosmetic oil bodies include, for example, vegetable oils, liquid paraffin oils, isoparaffin oils and synthetic hydrocarbons, and di-n-alkyl ethers having a total of between about 12 to about 36 carbon atoms, for example between about 12 to about 24 carbon atoms. Cosmetic agents used as contemplated herein contain at least one oil body, such as at least one oil body from the group of silicone oils. The group of silicone oils also includes, for example, dimethicones, which also include cyclomethicones, amino-functional silicones and dimethiconols. Dimethicones can be linear or branched, as well as cyclical or cyclical and branched. Suitable silicone oils or silicone gums are, for example dialkyl-and alkylarylsiloxanes, such as dimethylpolysiloxane and methylphenylpolysiloxane, and alkoxylated, quaternized or anionic derivatives thereof. Cyclical and linear polydialkylsiloxanes, alkoxylated and/or aminated derivatives thereof, dihydroxypolydimethylsiloxanes and polyphenylalkylsiloxanes are exemplary.
Ester oils, i.e. esters of 6-C30 fatty acids with C2-C30 fatty alcohols, for example monoesters of fatty acids with alcohols having from about 2 to about 24 carbon atoms, such as isopropyl myristate (Rilanit® IPM), isononanoic acid C16 -18 alkyl esters (Cetiol® SN), 2-ethylhexyl palmitate (Cegesoft® 24), stearic acid-2-ethylhexyl ester (Cetiol® 868), cetyl oleate, glycerol tricaprylate, coconut fatty alcohol caprinate/caprylate (Cetiol® LC), N-butyl stearate, oleyl erucate (Cetiol® J 600), isopropyl palmitate (Rilanit® IPP), oleyl oleate (Cetiol®), lauric acid hexyl ester (Cetiol® A), di-n-butyl adipate (Cetiol® B), myristyl myristate (Cetiol® MM), cetearyl isononanoate (Cetiol® SN), oleic acid decyl ester (Cetiol® V) are additional exemplary care oil bodies.
Furthermore, dicarboxylic acid esters, symmetrical, asymmetrical or cyclic esters of carbonic acid with fatty alcohols, trifatty acid esters of saturated and/or unsaturated linear and/or branched fatty acids with glycerol or fatty acid partial glycerides, which are to be understood as monoglycerides, diglycerides and technical mixtures thereof are suitable as care substances.
Furthermore, emulsifiers and/or surfactants may be contained in the inventive preparation. PEG derivatives of hydrated castor oil are exemplary, which are available, for example, under the name PEG Hydrogenated Castor Oil, such as PEG-30 Hydrogenated Castor Oil, PEG-33 Hydrogenated Castor Oil, PEG-35 Hydrogenated Castor Oil, PEG-36 Hydrogenated Castor Oil oder PEG-40 Hydrogenated Castor Oil. As contemplated herein, use of PEG-40 Hydrogenated Castor Oil is exemplary. These are possibly contained in a quantity of from about 0.05 to about 1.5 wt. %, such as from about 0.1 to about 1.0 wt. %, also for example from about 0.2 to about 0.8 wt. % or from about 0.3 to about 0.6 wt. %.
The cosmetic agents contain the ingredients and/or active ingredients in a cosmetically acceptable carrier.
Suitable cosmetically acceptable carriers are aqueous, alcoholic or aqueous-alcoholic media having at least about 10 wt. % water, relative to the total weight of the agent.
It is contemplated that the cosmetic carrier contains water, particularly in a quantity that is at least about 10 wt. %, such as at least about 20.0 wt %. for example at least about 40 wt. % water relative to the total weight of the agent. Exemplary cosmetic agents have a proportion of water between about 50 and about 95 wt. %, such as between about 60 and about 90 wt. % and for example between about 65 and about 85 wt. %, relative to their total weight.
Low alcohols having from about 1 to about 4 carbon atoms conventionally used for cosmetic purpose, such as ethanol and isopropanol, can be used, for example as alcohols.
Examples of water-soluble solvents as a cosolvent are glycerol and/or ethylene glycol and/or 1,2-propylene glycol in a quantity of from about 0 to about 30 wt. % relative to the total agent.
