    [0004] TECHNICAL SECTOR
    [0005] The present invention falls within the cosmetic sector. More in particular, it relates to a new graphene-based cosmetic composition.
    [0007] BACKGROUND OF THE INVENTION
    [0008] Graphene is a two-dimensional carbon-based material with sp2 hybridization. It is a single atom thick sheet of carbons with the atoms arranged in a regular hexagonal pattern. A graphene sheet has lateral dimensions in the range of nanometers to microns.
    [0010] Fully exfoliated graphene has been estimated to have a high specific area of about 2,650 m2 / g.
    [0012] While graphene only contains carbon in its composition and its geometry is ideal, there are a number of related two-dimensional materials that can be considered derivatives of graphene. These related graphene materials include graphenes with structural defects and graphenes containing heteroatoms. Structural defects in graphenes can be one or more carbon vacancies in the lattice and the presence of rings of five, seven or more members. Heteroatoms can consist of oxygen, nitrogen, sulfur, boron, or other elements. The percentage of doping heteroatoms can vary between very low values (of approximately 0.01% by weight) up to 60% by weight, being usual percentages between 1% and 5% by weight with respect to the total.
    [0014] A special case of a graphene derivative is graphene oxide. Graphene oxide is also a two-dimensional material, but its oxygen content can vary between 30% and 60% by weight, with usual values being around 50% by weight with respect to the total. In graphene oxide there are oxygenated groups such as epoxide groups, hydroxyl groups and / or carboxylic groups, which are easily functionalized. Graphene oxide is easily reduced to a material with a residual oxygen content of around 10% by weight with respect to the total. This type of graphene oxide is known as reduced graphene oxide.
    [0016] It is therefore a material with unique properties, among which it is worth highlighting its almost complete transparency to visible radiation, high electrical and thermal conductivity, metallic luster, high modulus of elasticity and extraordinary toughness at break, among others.
    [0018] Due to its optimal properties, there are numerous patents relating to inventions based on the use of graphene in many different applications.
    [0020] Thus, for example, the application KR20170106062 refers to a cosmetic composition for sun protection that comprises graphene as an active ingredient.
    [0022] In turn, the application MX2017017077 refers to a process for the preparation of a cosmetic cream that comprises adding graphene oxide as an active ingredient.
    [0024] The application CN108030704 refers to a hair dye comprising graphene oxide.
    [0026] However, no invention with the attributes of the cosmetic product object of the present patent application has been described to date.
    [0028] Said cosmetic composition arises from the interest of consumers to acquire quality products, seeking increasingly effective, safe, pure and allergen-free ingredients.
    [0030] The object of the invention solves this need, presenting unique properties compared to other cosmetic compositions known in the state of the art.
    [0032] DESCRIPTION OF THE INVENTION
    [0033] The object of the invention is therefore a cosmetic composition characterized in that it comprises between 0.05% and 15% by weight, and more preferably between 1% and 5% by weight of a functionalized graphene derivative, preferably functionalized with at least one positively charged molecule.
    [0034] By graphene derivative is meant modified graphene or doped graphene.
    [0036] Preferably, the doped graphene may consist of graphene characterized by comprising at least one heteroatom selected from a group preferably consisting of oxygen, nitrogen, sulfur and boron, as well as any of their combinations. The percentage of doping heteroatoms will preferably be between 0.01% and 60% by weight, and more preferably between 1% and 5% by weight relative to the total.
    [0038] Likewise, in an especially preferred embodiment of the invention, the graphene derivative will be graphene oxide, with an oxygen content preferably between 30 and 60% by weight, or reduced graphene oxide, with an oxide content preferably between between 5 and 20% by weight.
    [0040] Another object of the invention is a cosmetic product characterized in that it comprises the cosmetic composition described above. Preferably, said cosmetic product can consist of a hair product, preferably a shampoo or a conditioner.
    [0042] It has been shown that the application of the claimed cosmetic composition on the hair offers numerous advantages, such as thermal protection of the hair, the contribution of shine, the maintenance of color and the cleaning of the hair for a longer time or the anti-breakage and regeneration capacity hair related. In a particular embodiment in which graphene is functionalized with a positive charge, the above properties will be optimized, since damaged hair is characterized by having a negative charge and, therefore, the affinity for it will be greater. Specifically, the hair cuticle is made up of anionic amino acids and this causes the hair to have a mostly negative charge. When the cuticle is damaged or lost, the hair becomes more reactive, the amino acids acquire a negative charge and the undesirable effects of frizz, brittleness and loss of shine and / or color appear.
    [0044] In preferred embodiments of the invention, the molecules introduced into graphene for its functionalization, in addition to providing the graphene with a positive charge, will have the ability to selectively interact with amino acids in hair, such as cysteine, improving the properties of the cosmetic product.
    [0046] PREFERRED EMBODIMENT OF THE INVENTION
    [0047] As described above, the object of the invention refers to a cosmetic composition characterized in that it comprises between 0.05% and 15% by weight of a functionalized graphene derivative, preferably functionalized with at least one positively charged molecule. Said positively charged molecule can consist of a low molecular weight molecule (preferably less than 200 g / mol), but it can also consist of at least one oligomer and / or polymer.
    [0049] Preferably, the positively charged molecule may be selected from a group consisting of a quaternary ammonium cation, a phosphonium cation, a sulfonium cation, a cation derived from the amine group, a guanidinium cation, and a cation derived from the imine group, thus as any of its derivatives and combinations.
    [0051] In a particular embodiment of the invention, the functional group introduced into graphene will be at least one nitrogen-based molecule preferably selected from a group consisting of choline, diethylenetriamine, triethylenetetramine, glucosamine and chitosan, as well as any of their combinations.
    [0053] In particular embodiments of the invention, the functionalized graphene may comprise between 1 and 25% by weight, and more preferably between 8 and 15% by weight with respect to the total weight of graphene, of a molecule with a positive charge, it being preferable that this molecule is one of those mentioned in the previous paragraphs.
    [0055] The claimed cosmetic composition may be used as a base for the preparation of cosmetic products and preferably hair products such as shampoos or conditioners, among other examples.
    [0057] Thus, in a preferred embodiment of the invention in which the cosmetic product consists of a lauryl sulfate-based shampoo, the shampoo formula may comprise an aqueous suspension of between 0.05% and 15% by weight of a derivative of graphene (modified graphene or doped graphene, preferably graphene oxide or reduced graphene oxide) functionalized, at least one anionic surfactant (preferably sodium lauryl sulfate), in a percentage preferably between 15% and 50% by weight and, preferably, at least one additional ingredient selected from a group consisting of at least one conditioning agent, at least one wetting agent , at least one nonionic surfactant, at least one amphoteric surfactant, at least one preservative, at least one pH regulator and at least one suspending agent, as well as any of their combinations.
    [0059] In an especially preferred embodiment of the invention, the shampoo may comprise in percentage by weight with respect to the total:
    [0061]
    [0062]
    [0065] In another particularly preferred embodiment of the invention, the claimed cosmetic composition may be the base of a sulfate-free shampoo. These types of shampoos are especially advantageous products, as they maximize the color protection properties, being more respectful of the hair fiber. In this particular embodiment, the shampoo may comprise the same ingredients that have been described in the previous table regarding the composition of a lauryl sulfate-based shampoo, with the difference that the surfactant may preferably be selected from:
    [0066] • 15 to 50% and more preferably 25 to 35% by weight of an anionic surfactant, preferably selected from the group consisting of sodium alpha-olefin sulfonate, disodium lauryl sulfosuccinate, sodium carboxylate, cocoyl isethionate sodium and sodium lauryl sarcosinate, as well as any of their combinations;
    [0067] • 0 to 20% and more preferably 15 to 20% by weight of an amphoteric surfactant preferably selected from cocoamidopropyl betaine and sodium cocoamphoacetate, or both;
    [0068] • 0 to 20% and more preferably between 2 and 7.5% by weight of a nonionic surfactant, preferably an alkylpolyglucoside selected from coconut glucoside, decyl glucoside and lauryl glucoside, as well as any of their combinations;
    [0069] including any combination of the foregoing surfactants.
    [0071] The cosmetic composition object of the invention has been specifically designed to be compatible with the aqueous phase of cosmetic formulations. In this way, the process for obtaining the cosmetic product may be based on a conventional process, comprising in one of its stages the addition of an aqueous suspension of the claimed composition based on at least one functionalized graphene derivative.
    [0073] In a particular embodiment in which the cosmetic product is a shampoo, the functionalized graphene derivative (modified graphene or doped graphene, preferably graphene oxide or reduced graphene oxide) can be added in a aqueous suspension preferably obtained under stirring at a speed of between 150 and 500 rpm and a temperature of between 20 and 25 ° C. The rest of the components may be added following the usual order of the conventional processes for obtaining each particular cosmetic product.
    [0075] Thus, for example, in the specific case in which the cosmetic product is a shampoo, the process may include:
    [0076] (a) obtain an aqueous suspension of a graphene derivative (modified graphene or doped graphene, preferably graphene oxide or reduced graphene oxide) functionalized by stirring at a speed between 100 and 500 rpm and a temperature between 20 and 25 ° C;
    [0077] (b) if necessary, add the suspending agent with stirring, preferably at a speed between 100 and 500 rpm;
    [0078] (c) optionally, if necessary due to the type of suspending agent used, add the pH regulator until obtaining a pH between 4 and 7;
    [0079] (d) then adding the preservative and at least one surfactant selected from a nonionic surfactant and / or an amphoteric surfactant;
    [0080] (e) if necessary, add the conditioning agent and the emollient;
    [0081] (f) finally, adjust the pH with a pH regulator, until obtaining a pH between 4 and 7.
    [0083] The amounts of each compound may vary according to the ranges that have been previously described.
    [0085] In another particular embodiment of the invention, the cosmetic composition may be used as the base of a cosmetic product that may consist of a mask or conditioner. In this case, the formulation may comprise an aqueous suspension of between 0.05% and 15% by weight of a graphene derivative (graphene oxide, reduced graphene oxide, doped graphene or other modified graphene) functionalized and, preferably, al least one additional ingredient selected from a group consisting of at least one rheological modifier, at least one preservative, at least one humectant, at least one emulsifier, at least one fatty phase, at least one conditioning agent and at least one pH regulator , as well as any of its combinations.
    [0086] In particular, the conditioner may comprise as a percentage by weight with respect to the total:
    [0088]
    [0091] The procedure for obtaining the previously described conditioner formulation is characterized in that it comprises:
    [0092] (a) obtain an aqueous suspension of at least one graphene derivative (modified graphene or doped graphene, preferably graphene oxide or reduced graphene oxide) functionalized by stirring at a speed between 100 and 500 rpm and a temperature between 20 and 25 ° C;
    [0093] (b) optionally, heating to a temperature of 75 to 80 ° C;
    [0094] (c) adding at least one preservative, at least one humectant / emollient and at least one rheological modifier, giving rise to a first phase;
    [0095] (d) in a separate container, prepare a second, oily phase, by mixing at least one emulsifier and the fatty phase, as a consistency factor. This second oil phase is preferably heated to a temperature between 75 and 80 ° C;
    [0096] (e) when both phases are at the same temperature, they are mixed with stirring until an emulsion is obtained;
    [0097] (f) once the emulsion is obtained, it is cooled, also under stirring, to room temperature, preferably between 20 and 30 ° C;
    [0098] (g) finally, the pH is adjusted with a pH regulator, preferably to a pH of 3.5 to 5, and more preferably 4.5.
    [0100] In order to test the efficacy of the object of the invention, a series of tests were carried out which were compared with a blank. The results of the tested evaluation methods are summarized below:
    [0102] 1. Panel of experts
    [0104] A defined number of individuals evaluated the treatments of natural and colored hair strands after treatment with two cosmetic products (a shampoo and a conditioner, as previously described). For each of the treatments, they answered a series of questions (variables) that included perception during product application, wet finish, dry finish and general perception of the treatment.
    [0106] The treatments were carried out comparing a blank (0) with two types of cosmetic products, GC and GD: •
    [0108] • GC - characterized by comprising between 1 and 5% by weight of graphene oxide obtained by chemical oxidation by the Hummers-Offeman method, with 58% by weight of modified carbon content by reaction with an identical weight of chitosan of a degree of deacetylation greater than 85%, by reaction at room temperature (20-25 ° C) in aqueous medium for 5
    [0110] • GD - characterized by comprising between 1 and 5% by weight of graphene oxide obtained by chemical oxidation by the Hummers-Offeman method with 58% by weight of modified carbon content by reaction with an equivalent weight of diethylenetriamine ( DETA) by reaction at room temperature (20-25 ° C) in aqueous medium for 5 h.
    [0112] As a result of the panel of experts, all the participants chose the treatments with GC and / or GD molecules over white, reporting better combability, softness, frizz and color protection during the application of the formulas and after dry and wet finishes. .
    [0114] 2. Assessment of color loss
    [0116] To assess color protection, blonde hair locks were dyed to a C5.6 reddish shade with hair dye. The hair was left with the dye for 30 minutes and then rinsed with a control shampoo.
    [0118] Before carrying out the treatments, an initial measurement of the color was carried out with a Konica Minolta type spectrophotometer. The measurements were made on the CIE 1976 L * a * b scale and the value obtained by the following formula was taken as a reference to evaluate the differences in color:
    [0120]
    [0123] After applying the different treatments for 10 consecutive washes, the differences were significant for color protection, being especially evident with the GD product, which corresponds to graphene oxide modified with DETA. In particular, the AE value was 27 for GC, 25 for GD, and 32 for blank. In this regard, it is important to note that the lower the AE value, the less the color loss.
    [0125] 3. Evaluation of combability
    [0127] Using a high precision dynamometer, a support was placed to fix a strand of hair and a comb. The difference in force required in each case was observed and evaluated on the treated strands. In products with a low level of conditioning, high resistance values were found when passing the comb over the lock, while for highly conditioning products it was observed how the force was significantly reduced.
    [0129] These force values were extrapolated and related to the softness of the hair.
    [0131] In products that require less force, the hair is more careful, since brushing is easier and the hair breaks less.
    [0133] For the hair in which the functionalized graphene oxide treatments were applied, lower strength values were obtained than in the case of the control treatment, which indicates that it has a conditioning effect on the hair that improves combability and therefore reduces its breakage.
