    专利说明:

    The application relates to a hair treatment agent making it possible to strengthen the internal structure of the hair with a polyvalent cation.
    Hair can be damaged by naturally or artificially induced processes The most important type of damage can be oxidative damage.
    Natural processes can, for example, exhibit a combined (e.g. simultaneous) action of UV light and oxygen (O2) on the hair.
    Artificially induced processes may include, for example, applying a hair dye (also called hair color), blonde coloring and / or generating a perm. In particular, hair dyes play an important role in hair cosmetics.
    In addition to the desirable cosmetic effects, such as, for example, the lightening of the hair, severe damage can also occur in the hair, for example when using oxidizing agents.
    The damage process can be caused by an oxidation of amino acids, for example an oxidation of the amino acids cystine and cysteine to cysteic acid, which are very common in the hair. Cystine can form intermolecular disulfide bridges (also called SS bridges) in the hair, so cystine is extremely important for the mechanical stability of the hair.
    The oxidation of these bridges to cysteic acid can destroy the mechanical stability of the hair and even lead to complete breakage of the hair in the event of multiple applications. A loss of mechanical stability can lead to increased swelling of the hair in water.
    However, properties of the hair already macroscopically perceptible previously, for example tangible, for example a surface roughness, can be negatively influenced.
    An object of the present invention is to provide a hair treatment agent which, in particular for hair damaged by oxidation, is capable of reconstructing the intermolecular compounds damaged in the hair fibers and thus strengthening the internal structure of the hair.
    It has been found that a hair treatment agent which contains, in addition to a polyvalent metal salt, a selected organic fatty acid and has a pH of 3.5 to 5, is remarkably suitable for this purpose.
    A first object of the invention is thus a hair treatment agent making it possible to strengthen the internal structure of the hair with a pH of 3.5 to 5, containing - relative to the total amount of hair treatment agent -
    a) from 0.01 to 10% by weight of polyvalent metal salt, the metal salt being chosen from the group consisting of strontium salts, zirconium salts, hafnium salts, titanium salts, salts tin, aluminum salts, bismuth salts, lanthanum maleate, lanthanum chloride and mixtures thereof, and
    b) from 0.01 to 10% by weight of an organic acid chosen from the group consisting of tartaric acid, citric acid, maleic acid, fumaric acid, salicylic acid, acid lactic, malic acid, amino acids and mixtures thereof.
    Among the suitable hair treatment agents are preferably hair cleaning agents such as shampoos, hair care agents such as hair masks, hair care rinses or sprays, and styling agents such as hair gels, hair sprays or hair waxes. In a particularly preferred manner, the hair treatment agent is a shampoo or a hair care product. It is particularly preferred that the hair care product is applied after bleaching or oxidative coloring of the hair.
    Hair treatment agents must contain a polyvalent metal salt, the metal salt being chosen from the group consisting of strontium salts, zirconium salts, hafnium salts, titanium salts, tin salts, aluminum salts, bismuth salts, lanthanum maleate, lanthanum chloride and mixtures thereof. The hair treatment agents preferably contain a trivalent or tetravalent metal salt, in particular an aluminum salt, a zirconium salt, a lanthanum maleate, a lanthanum chloride or a mixture thereof.
    Particularly preferred polyvalent metal salts include lanthanum maleate, lanthanum chloride, an aluminum salt or a mixture thereof.
    In a particularly preferred embodiment, the hair treatment agent contains lanthanum maleate, lanthanum chloride and / or aluminum lactate as the polyvalent metal salt.
    In a most particularly preferred embodiment, the hair treatment agent contains lanthanum maleate and / or aluminum lactate as the polyvalent metal salt.
    The hair treatment agents preferably contain - relative to their weight - preferably 0.1 to 7.5% by weight and more preferably 0.5 to 5% by weight of polyvalent metal salt, preferably lanthanum maleate, lanthanum chloride and / or aluminum lactate and preferably lanthanum maleate and / or aluminum lactate.
    Hair treatment agents contain as a second essential ingredient - relative to their weight - 0.01 to 10% by weight of a chosen organic acid.
    The organic acid is chosen from the group consisting of tartaric acid, citric acid, maleic acid, fumaric acid, salicylic acid, lactic acid, malic acid, amino acids and mixtures of these. Suitable amino acids include glycine, glutamic acid, arginine and / or aspartic acid. Lactic acid and / or maleic acid are particularly preferably used as organic acid.
    The hair treatment agents contain the organic acid preferably in an amount of 0.1 to 5% by weight and in a particularly preferred manner of 0.5 to 3% by weight, each time relative to the weight of the agent. hair treatment ready to use.
    On the one hand, the organic acids serve to bring the pH of the hair treatment agent between 3.5 and 5, and
    In a preferred embodiment, the hair treatment agent has a pH of between 3.75 and 4.75.
    It has been found that the use of an organic acid chosen in combination with a polyvalent metal salt confers remarkable properties on hair treatment agents. In particular, hair treated with these hair treatment agents has a stronger internal structure, which is manifested by a higher denaturing temperature, increased tear resistance and reduced swelling in water. This applies in particular to the application to hair damaged by oxidation.
    It has been found that it is particularly effective and that strengthening the internal structure is particularly important when the hair treatment agents contain lanthanum maleate and maleic acid, lanthanum chloride and lactic acid or aluminum lactate and lactic acid.
    The hair treatment agent preferably also contains an aqueous or hydroalcoholic support. An aqueous support contains at least 50% by weight of water. Within the meaning of the present invention, the hydroalcoholic supports are aqueous solutions containing from 3 to 70% by weight of C2-C 6 alcohol, in particular ethanol or propanol, isopropanol, butanol, isobutanol, tert-butanol, n-pentanol, iso-pentanols, n-hexanol, iso-hexanols, glycol, glycerol, 1,2-pentanediol, 1,5-pentanediol, 1,2- hexanediol or 1,6-hexanediol. The agents can also contain other organic solvents, such as, for example, methoxybutanol, benzyl alcohol, ethyldiglycol or 1,2-propylene glycol. All water-soluble organic solvents are preferred.
    Hair treatment agents can in principle be applied to all dyed hair. However, it is particularly advantageous to apply the hair treatment agents to damaged hair, in particular hair damaged by oxidation. Hair damaged by oxidation is in particular hair having a cysteic acid content greater than 1% by weight. Consequently, the hair treatment agents are particularly suitable for being applied to bleached or color-treated hair by oxidation.

    2. PSC measures
    2.1 Background
    Hair is a material containing keratin which has a fine complex morphological structure. For mechanical or thermal studies, the structure can be simplified as a two-phase filament / matrix composite in which the helical filaments a are embedded in an amorphous matrix. These two dominant compounds largely determine the mechanical properties of human hair. The maximum temperature values provide information on the damage or integrity of the matrix and the propeller a. The looser the matrix (less cross-linked) or the smaller the crystals of the α-helical phase, the lower the maximum temperature.
