Description

Description Title of the invention: Natural hair gel with carrageenan and a film-forming agent

[0001] — The present invention relates to cosmetic agents for transformation temporary keratin fibers, particularly human hair, in a support cosmetic comprising a film-forming agent and a natural thickener.

[0002] — Cosmetic agents that contribute to permanent shaping or Temporary hair extensions play an important role in cosmetics. Styling temporary, which must provide good support without harming the healthy appearance of the Hair, such as its shine, can for example be achieved using hairsprays, hair waxes, hair gels, hair mousses, etc.

[0003] — The most important property of an agent for the temporary shaping of fibers The keratin-based properties give the treated fibers the strongest possible hold. in the molded form. If the keratin fibers are human hair, we are talking about also strong hold of the hairstyle or high degree of fixation of the agent cosmetics. The hold of the hairstyle is determined primarily by the type and the quantity of polymers used.

[0004] — In the current state of the art, many cosmetic agents are known which provide temporary formatting. The corresponding agents contain gen- synthetic polymers are generally used as shaping components. Furthermore, temporary shaping agents often contain syn- polymers Therapeutic agents act as viscosity modifiers. Formulations containing a Dissolved or dispersed polymers can be applied to the hair using a propellant gas or a pumping mechanism. However, gels and waxes for the hair is not usually applied directly to the hair, but” are applied using a comb or by hand.

[0005] — Polymer ingredients have different functions in setting agents temporary form. Thus, substances modifying viscosity can be formed at starting from polymers. Polyelectrolytes are often used here. In addition, the substances that are ultimately responsible for maintaining the hairstyle are Polymer components. Synthetic polymers commonly used in agents temporary shaping agents are produced from the corresponding synthetic monomers weighting. These monomers are obtained from fossil substances such as petroleum, by conversion into corresponding polymer blocks, notably using energy. Since monomers are already produced synthetically, polymers The most commonly used are fully synthetic polymers. In the context of more sustainable use of raw materials and energy, it remains desirable to use only cosmetic raw materials derived from renewable resources in cosmetic products, using as little energy as possible. However, a reduction in the quantity, or even a substitution, of these entirely synthetic polymers can only be carried out if the replacement polymers provide the desired properties for the intended use and give the keratin fibers sufficient and stable shape retention.Many other properties that cosmetic agents impart to hair must still be preserved in a reduction in quantity or an exchange of entirely synthetic polymers. For example, cosmetic agents give hair volume, and the bounce and suppleness of keratin-containing fibers fixed in their shape must be maintained. The formation of polymer particles visible to the naked eye on keratin fibers must be avoided. Furthermore, the keratin-containing fiber must not appear dull but should take on a natural color. These advantageous properties, along with others, that cosmetic agents impart to hair are referred to hereafter as "styling properties." Developing cosmetic agents that possess all the desired styling properties still presents challenges.This relates in particular to the combination of strong adhesion on the one hand, and simple and uniform application on keratin fibers on the other. Ultimately, the appearance of the cosmetic product itself must be appealing to trigger a purchase decision. With styling agents, especially hair gels, customers typically expect a transparent gel. When replacing entirely synthetic polymers, no disadvantages should occur in terms of the cosmetic product's physical appearance. The object of the invention is to provide a suitable cosmetic agent for the temporary transformation of keratin-containing fibers, wherein the use of fully synthetic polymers is considerably reduced or in which the use of fully synthetic polymers is abandoned, the styling properties being maintained at a high level and the cosmetic product being expected to show a pleasing physical appearance. The objective assigned to the invention is achieved by the object of claim 1. A first object of the invention is therefore a cosmetic agent for the temporary transformation of keratin fibers, in particular human hair, in a cosmetic support comprising a film-forming agent and a natural thickener, the natural thickener comprising carrageenan and / or its salts, and the film-forming agent comprising a starch compound modified by hydroxypropyl groups. The cosmetic agent contains carrageenan and / or its salts as a natural thickener. "Natural thickener" means that the thickener comes from a natural source and is therefore not synthetic. "Carrageenan" is the collective name for a group of long-chain carbohydrates that can be extracted from red algae cells. Carrageenans are linear anionic hydrocolloids distinguished by their chemical structure and exhibiting different properties. These different types vary in the proportion of galactose and 3,6-anhydrogalactose, as well as in the number of sulfate groups. The sulfate groups can be in their protonated form as free acid groups or as salts. The thickener is carrageenan. Carrageenan is commercially available. According to the present invention, the cosmetic agent comprises a film-forming agent. A "film-forming agent" is defined as a polymer that deposits a continuous film on the skin, hair, or nails upon drying. These film-forming agents can be used in a wide variety of cosmetic products, such as masks, makeup, hair styling products, hair sprays, hair gels, hair waxes, hair treatments, shampoos, or nail polishes. Polymers with sufficient water solubility are preferred. This allows for the production of solutions that are easy to apply or process. In the context of the present invention, "film-forming agent" means in particular polymers which can be absorbed onto the hair in the form of a transparent polymer film when used in an aqueous, alcoholic or hydroalcoholic solution of 0.05 to 20% by weight (relative to the total weight of the cosmetic agent). The film-forming agent is a hydrophobically modified starch compound, namely a starch compound modified by hydroxypropyl groups. It has been surprisingly discovered that a cosmetic agent that can be substantially free of fully synthetic film-forming agents and that contains a starch compound modified by hydroxypropyl groups and carrageenan can be formulated without having to consent to the loss of styling properties. Starch belongs to the homoglycan family and is a polycondensation product of D-glucose. In this case, starch consists of three structurally distinct polymers of D-glucopyranose: amylose, amylopectin, and an intermediate fraction. Higher plants contain 0 to 45% amylose by weight, relative to their dry matter. The intermediate fraction, also called abnormal amylopectin, is structurally located between amylose and amylopectin. The quantities specified for amylopectin in this application include the intermediate fraction. Starch is also a storage carbohydrate which is stored by many plants in the form of starch grains (granules), usually measuring from 1 to 200 µm, in various parts of the plants, for example in tubers or roots, seeds, fruits and pulp. Preferably, the hydrophobically modified starch compound used according to the invention should have an amylose content of less than 25% by weight, and in particular less than 20% by weight, in each case relative to the weight of the modified starch compound. It has been observed that a starch containing 17 to 22% by weight of amylose and 78 to 83% by weight of amylopectin is particularly suitable for achieving the desired styling properties. Amylose is composed of D-glucose linked α,4-glycosidically, with the M number ranging from 50,000 to 150,000. The resulting chains form double helices in starch. Amylopectin contains, in addition to the α-1,4 linkages described for amylose, 4 to 6% α-1,6 linkages as branch points. The average distance between branch points is approximately 12 to 17 glucose units. The molar mass of 10⁷ to 7 x 10⁸ corresponds to approximately 10⁵ glucose units, placing amylopectin among the largest biopolymers. These branches are distributed throughout the molecule in such a way that a spike-like structure with relatively short side chains develops. Two of these side chains each form a double helix. Due to the numerous branching points, amylopectin is relatively soluble in water. Due to the different structure of carbohydrates, some natural sources are more or less suitable for starch. According to a preferred embodiment of the present invention, the base of the starch compound modified by hydroxypropyl groups is a starch of vegetable origin, preferably obtained from potatoes, maize, rice, peas, acorns, chestnuts, barley, wheat, bananas, millet, sorghum, oats, rye, beans, sweet potatoes, arrowroot, cassava, tapioca, and / or sago, particularly potatoes and / or tapioca. The strengths of this origin are of particular importance for solving the problem underlying the invention. By "hydroxypropyl-modified starch compound" is meant a reaction product of starch and propylene oxide. Such a reaction product preferably comprises at least one structural unit of formula (PS), [Chem.1] in which at least one radical R, R' or R'° is a group of formula The valence equal to 0, and at most 2 of the radicals of R, R°, R°' is a hydrogen atom. A bond marked with the symbol * in the formulas of this application corresponds to a free valence of the corresponding structural unit. The starch compound modified by hydroxypropyl groups is obtained, for example, by the reaction of native starch with propylene oxide. Before modification with propylene oxide, the starch may have been subjected to various physical or chemical processes, such as heat treatment, shearing, thermal cleavage, acid, oxidative, or enzymatic hydrolysis, etc. It is preferable that the starch compound modified with hydroxypropyl groups in the cosmetic agent not be in the form of simple starch grains (granules). To this end, the starch grains are released, for example by heat or shearing, and the corresponding polysaccharide molecules are released from the whole. The released polysaccharide molecules are modified after or before release using propylene oxide. In a preferred embodiment, starch modified with hydroxypropyl groups is gelatinized. If an aqueous suspension of starch is heated or compressed, tangential swelling of the particles is observed at critical temperature or pressure, with loss of birefringence, modification of the X-ray structure, and a sudden increase in the viscosity of the solution. This phenomenon is called gelatinization. Starch compounds modified with hydroxypropyl groups are present in the cosmetic agent according to a molecular weight distribution. Preferred starch compounds modified with hydroxypropyl groups have an average molecular weight of 50 to 2,500 kDa (weight average). The molecular weight distribution was determined experimentally using dextran filtration gel chromatography. Particularly preferred cosmetic agents contain such starch compounds modified by hydroxypropyl groups having an average molecular weight (weight average) of 100 to 2,000 kDa, in particular 500 to 1,800 kDa, most particularly preferred 700 to 1,000 kDa. To adjust the molecular weight, starch is subjected to mechanical and / or chemical treatment before or after modification using propylene oxide. To increase the molecular weight, the starch can be crosslinked. Crosslinking of starch compounds modified with hydroxypropyl groups occurs when the linear or branched polysaccharide macromolecules of the starch are covalently linked by a crosslinking agent to form a three-dimensional, insoluble, and also inflatable polymer network. Native starch is generally considered uncrosslinked and, if crosslinking is desired, requires artificial crosslinking through synthetic chemistry. Such artificial crosslinking can be achieved with crosslinking agents. Starch compounds modified with hydroxypropyl groups that do not exhibit such crosslinking are not crosslinked. Crosslinking is achieved, for example, using epichlorohydrin as a crosslinking agent. To this end, a 42% by weight mixture of starch compound modified with hydroxypropyl groups is prepared in water, the desired quantity of epichlorohydrin is added at room temperature, and the crosslinked starch is isolated by conventional methods after stirring for 1 to 5 hours under viscosity control once the target viscosity is reached. However, it is particularly preferred according to the invention that the cosmetic agent contain, as a starch compound modified with hydroxypropyl groups, at least one non-crosslinked starch compound modified with hydroxypropyl groups. To achieve a molecular weight of 100 to 400 kDa, these starches are preferably subjected to mechanical cleavage, enzymatic cleavage (in particular with alpha-amylase, beta-amylase, glucoamylase, or debranching enzymes), cleavage by acid hydrolysis (in particular with hydrochloric acid, sulfuric acid, or phosphoric acid), thermal cleavage, or reaction with oxidizing agents (such as periodate, hypochlorite, chromic acid, permanganate, nitrogen dioxide, hydrogen peroxide, or organic percarboxylic acid, preferably with hydrogen peroxide). Kneaders, extruders, stator / rotor machines, or agitators are suitable for the mechanical fractionation of starch. Oxidative cleavage using hydrogen peroxide is preferred according to the invention. For this purpose, for example, starch compounds modified with hydroxypropyl groups are added to water and heated to a temperature of 50 to 70 °C, hydrogen peroxide is added, and the mixture is stirred at a temperature of 70 to 85°C for 2 to 5 hours. The propylene oxide content of starch affects the suitability of hairstyles for hair, their flexibility, and the stability of cosmetic agents. It has been found that these parameters are further optimized when the starch compound modified with hydroxypropyl groups has—based on the weight of the modified starch compound—a propylene oxide content of 1 to 20% by weight, preferably a propylene oxide content of 4 to 12% by weight, and most preferably a propylene oxide content of 9.5 to 10.5% by weight. The propylene oxide content can be determined, for example, after Hodges cleavage using the method according to DIN EN 13268 (publication date 2007-06). Furthermore, it has been found that such cosmetic agents are particularly well suited to the purposes of the invention; in these, the starch compound modified with hydroxypropyl groups in a 43% by weight aqueous solution exhibits a preferred viscosity in the range of 150 to 1,500,000 mPa·s (Brookfield viscometer, setting 7 at 20°C and 20 revolutions per minute). Particularly suitable starch compounds modified with hydroxypropyl groups exhibit viscosities between 10,000 and 200,000 mPa·s, particularly preferably between 25,000 and 180,000 mPa·s (measured in each case under the aforementioned conditions). According to a preferred embodiment of the present invention, the film-forming agent of the cosmetic agent shall consist "essentially" of the aforementioned hydrophobically modified starch compounds. In the context of the present invention, this may also preferably mean that the film-forming agent of the cosmetic agent comprises exclusively, i.e., 100% by weight relative to the total weight of the film-forming agent, the aforementioned hydrophobically modified starch compounds, in particular the starch compound modified by hydroxypropyl groups.The characteristic that the film-forming agent of the cosmetic agent is "essentially" composed of the component(s) is understood by those skilled in the art to mean that other components may be present in the cosmetic agent in a small proportion, for example up to 1% by weight, preferably up to 0.5% by weight, relative to the total weight of the cosmetic agent. These components may form part of the polymer film without, however, being considered a film-forming agent in the traditional sense. That is to say, the film formed from the film-forming agent may also contain other ingredients. According to a preferred embodiment of the present invention, the cosmetic agent is a cosmetic agent free of film-forming agent and entirely synthetic. The cosmetic agent of the preferred embodiment, traditionally, must be sens- likely free from polymers traditionally used as film-forming agents, which polymers are produced entirely synthetically. For the purposes of the present invention, a film-forming agent shall be considered to be produced entirely synthetically if all the monomers constituting said film-forming agent are traditionally produced synthetically.Examples of film-forming agents produced entirely synthetically include in particular acrylate-based or methacrylate-based copolymers, in particular those comprising, as monomeric ingredients, acrylic acid, methacrylic acid, alkyl (meth)acrylate or maleic anhydride; and copolymers comprising, as monomeric ingredients, N-vinylpyrrolidone, alkylvinyl ethers having alkyl groups of 1 to 18 carbon atoms and / or vinyl esters of carboxylic acids having 2 to 18 carbon atoms, in particular polyvinylpyrrolidone / vinyl acetate copolymers; and also polyvinylpyrrolidone, copolymers being understood as designating polymers which consist of two or more different monomers, and all the alkyl groups of said monomers may also be branched and / or functional groups. For the purposes of the present invention, the cosmetic agent may comprise up to 0.05% by weight of fully synthetic polymers, which, in the traditional sense, are film-forming agents, to be "substantially" free of fully synthetic film-forming agents. Preferably, the cosmetic agent may also be free of fully synthetic film-forming agents, i.e., the cosmetic agent comprises 0% by weight of fully synthetic film-forming agents. In the context of the invention, "keratin fibers" means fur, wool, feathers and in particular human hair. It has also been surprisingly discovered that a cosmetic agent containing a starch compound modified with hydroxypropyl groups and carrageenan can be formulated without compromising its styling properties, and that the cosmetic agent can be obtained in the form of a transparent gel. This results in a product with a pleasing appearance. In a preferred embodiment of the present invention, the weight ratio of the film-forming agent to the thickener is in the range of 40:1 to 1:2, preferably between 20:1 and 1:1, more preferably between 15:1 and 2:1, and in particular is approximately 5:1. At this preferred ratio of essential components in the cosmetic agent, the desirable physical appearance is achieved, and the styling properties are particularly advantageous.Because of these advantageous characteristics, the transparency of the mixture that constitutes the cosmetic agent is preferred. According to another preferred embodiment of the present invention, the support The cosmetic product includes water. More preferably, the cosmetic base comprises water acidified with a divalent or trivalent organic acid, in particular citric acid. According to other more preferred embodiments, the organic acid is a carboxylic acid, more preferably selected from the group consisting of formic acid, acetic acid, lactic acid, pyrrolidone carboxylic acid, tartaric acid, glycolic acid, nicotinic acid, hydroxyisobutyric acid, hydroxyisovaleric acid, or mixtures thereof. The acid and the natural thickener form an advantageous neutralizing product that can be produced, for example, in an aqueous medium by the addition of chitosan and the corresponding organic carboxylic acid, or a portion thereof. It has been discovered that cosmetic agents comprising film-forming agents including a neutralizing product of carrageenan and / or carrageenan with the above acids, especially with citric acid, and a starch compound modified by hydroxypropyl groups, cause styling properties reaching a level comparable with such cosmetic agents which include fully synthetic film-forming agents. According to the invention, it is preferred that the cosmetic agent comprise the starch compound modified by hydroxypropyl groups in an amount of 1.5% by weight to 20% by weight, preferably 2% by weight to 15% by weight, more preferably 3% by weight to 10% by weight, in each case relative to the weight of the cosmetic agent. According to another preferred embodiment of the present invention, the cosmetic agent contains a) 70 to 98% by weight, preferably 75 to 95% by weight, more preferably 80 to 90% by weight of water, b) 1.5 to 20% by weight, preferably 2 to 15% by weight, more preferably 3 to 10% by weight of starch compound modified by hydroxypropyl groups, and c) 0.5 to 10% by weight, preferably 1 to 7% by weight, more preferably 2 to 5% by weight of carrageenan, in each case, in relation to the total weight of the cosmetic agent. According to a preferred embodiment of the present invention, the cosmetic agent contains, in small quantities, a nourishing polymer, which is particularly preferably a cationic homopolymer. "Cationic polymers" are understood to be polymers having a group in the main and / or side chain, which group may be cationic in a "temporary" or "permanent" manner. According to the invention, "permanently" cationic polymers are defined as those Polymers exhibiting a cationic group independent of the agent's pH value. These are generally polymers containing a quaternary nitrogen atom, for example, in the form of an ammonium group. Quaternary ammonium groups are preferred cationic groups. In particular, such homopolymers, in which the quaternary ammonium group is linked via a C1-C4 alkylene group to a main homopolymer chain consisting of acrylic acid amide, the three alkyl groups being independently selected from the C1-C10 alkyl groups in addition to the C1-C4 alkylene group of the ammonium group, have been found to be particularly suitable. To compensate for the positive polymer charge, all possible physiologically acceptable anions can be used, such as chloride, bromide, hydrogen sulfate, methyl sulfate, ethyl sulfate, tetrafluoroborate, phosphate, hydrogen phosphate, dihydrogen phosphate or p-toluenesulfonate, triflate. According to a particularly preferred embodiment of the present invention, the cosmetic agent contains poly(3-acrylamidopropyl)trimethylammonium chloride as a nourishing cationic homopolymer. Most preferably, the nourishing homopolymer is used in an amount ranging from 0.0001% to 0.2% by weight, preferably in an amount ranging from more than 0.01% to less than 0.1% by weight, relative to the total weight of the cosmetic agent. Although these nourishing homopolymers are entirely synthetic polymers, they are used in very small quantities. Furthermore, acrylamide-based cationic homopolymers are not film-forming agents in the traditional sense due to their nature and definition. According to another preferred embodiment, the cosmetic agent further contains emulsifiers. Emulsifiers induce the formation of stable adsorption layers in water or oil at the phase interface. These layers protect the dispersed droplets from coalescence and thus stabilize the emulsion. Emulsifiers, like surfactants, consist of a hydrophobic molecular fraction and a hydrophilic molecular fraction. Hydrophilic emulsifiers preferentially form oil-in-water (O / W) emulsions, while hydrophobic emulsifiers preferentially form water-in-oil (W / O) emulsions. The choice of these emulsifying surfactants or emulsifiers depends on the substances to be dispersed, the specific external phase, and the desired consistency of the emulsion. According to a preferred embodiment of the present invention, the cosmetic agent further comprises a solubilizing agent which is preferably castor oil and / or an alkoxylated castor oil, more preferably castor oil. alkoxylated with 20 to 80, more preferably 30 to 50 ethylene oxide groups, in particular alkoxylated castor oil with 40 ethylene oxide groups. According to another preferred embodiment of the present invention, the cosmetic agent further contains a solubilizing agent, in particular alkoxylated castor oil with 40 ethylene oxide groups, in an amount of 0.05 to 2% by weight, preferably 0.1 to 1% by weight, more preferably 8 to 12% by weight, relative to the total weight of the cosmetic agent. The emulsifiers used preferably offer the advantage of being obtainable from natural raw material sources, and not entirely synthetic. To intensify the effects according to the invention, cosmetic agents preferably also contain at least one surfactant. Generally, nonionic, anionic, cationic, and ampholytic surfactants can be included in cosmetic products. The group of ampholytic or amphoteric surfactants includes zwitterionic surfactants and ampholytes. It has proven particularly advantageous for cosmetic agents to also contain at least one cationic surfactant to enhance their hair-conditioning properties. Cationic surfactants of the quaternary ammonium compound type, esterquats, and alkylamidoamines can be used in particular. Preferred quaternary ammonium compounds are ammonium halides, especially chlorides or bromides, such as chlorides alkyltrimethylammonium, dialkyldimethylammonium chlorides, and trialkylmethylammonium chlorides. The long alkyl chains of these surfactants preferably have 10 to 18 carbon atoms, such as, for example, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylammonium chloride, and tricetylmethylammonium chloride. According to a preferred embodiment of the present invention, alkyltrimethylammonium salts are used, more preferably salts of alkyltrimethylammonium in C12 to C20, particularly preferred of alkyltrimethylammonium chlorides in C16 to C18, in particular cetrimonium chloride. In a preferred embodiment of the present invention, the cosmetic agent contains from 0.01 to 4% by weight, particularly preferably from 0.1 to 3% by weight and in particular from 0.2 to 2% by weight of the cationic surfactant, the quantities relating to the total weight of the cosmetic agent. The ease of application of the cosmetic agent can be further improved by using small amounts of one or more polyalcohols. Preferred cosmetic agents contain one or more C3 to C12 alkane-1,2-diols, and The cosmetic agent particularly preferably contains C3 to C10 1,2-alkane(s). It particularly preferably contains propane-1,2-diol and caprylyl glycol. These diols improve ease of application, are somewhat nourishing, and are suitable for forming a stable emulsion with the preferred emulsifier. In a preferred embodiment of the present invention, the cosmetic agent contains 0.01 to 1.5% by weight, and more preferably 0.02 to 0.8% by weight, of the 1,2-alkane(s) relative to the total weight of the cosmetic agent. In a preferred embodiment of the present invention, the cosmetic agent contains at least one conditioning oil. Oils are advantageous as conditioning substances because they impart a silky shine to the hair and strengthen it by being absorbed. However, conditioning oils are much more demanding in terms of product formulation, as they must be incorporated stably without settling or forming a cream during long-term storage, which would be a drawback. According to a preferred embodiment of the present invention, the cosmetic composition comprises at least one conditioning oil and / or at least one conditioning ingredient, more preferably at least one natural conditioning oil, i.e., a substance comprising a triglyceride of indigenous origin, with vegetable conditioning oil(s) / vegetable conditioning ingredient(s) being particularly preferred. The conditioning ingredients must be non-polymer.We particularly prefer plant-based skincare oils from the group consisting of amaranth seed oil, argan oil, rice germ oil, baobab oil, Manetti oil, marula seed oil, yangu seed oil, rambutan oil, sea buckthorn oil, Tahitian monoi oil, tigernut oil, inca inchi oil, avocado oil, cottonseed oil, cupuaçu butter, cashew oil, thistle oil, peanut oil, jojoba oil, chamomile oil, coconut oil, pumpkin seed oil, poppy oil, evening primrose oil, and olive oil, rapeseed oil, soybean oil, sunflower oil and wheat germ oil, in particular 1'(-)-a-bisabolol, hydrogenated jojoba oil and / or coconut oil.As a particularly preferred skincare ingredient, the cosmetic agent includes D-panthenol. The advantage of these skincare oils or ingredients is that they are largely derived from natural sources and therefore represent energy- and resource-efficient raw materials. Depending on the preferred embodiment, the cosmetic agent may contain, on a total weight basis, from 0.0005 to 3% by weight, preferably from 0.001 to 2% by weight, and particularly preferably from 0.05 to 1% by weight of the total skincare oils and ingredients.
