COMPOSITIONS CAPILLAIRES, DESTINEES NOTAMMENT A LA
NEUTRALISATION DE L'ACIDE LACTIQUE DU CUIR CHEVELU ET
METHODE DE TRAITEMENT COSMETIQUE DU CUIR CHEVELU
L'invention a pour objet des compositions capillaires, destinées notamment à la neutralisation de l'acide lactique du cuir chevelu, un procédé de neutralisation de l'acide lactique du cuir chevelu, et une méthode de traitement cosmétique du cuir chevelu.HAIR COMPOSITIONS, ESPECIALLY FOR THE
NEUTRALIZATION OF LACTIC ACID FROM SCALP AND
COSMETIC TREATMENT METHOD FOR SCALP
The subject of the invention is hair compositions, intended in particular for neutralizing lactic acid from the scalp, a method for neutralizing lactic acid from the scalp, and a method for cosmetic treatment of the scalp.
L'expérience a montré que les sujets ayant une hyperhydrose anormale du cuir chevelu, présentaient une certaine fragilité de la résistance de leurs cheveux, ceux-ci s'arrachant facilement avec leur bulbe, contrairement aux cuirs chevelus traités par de l'aspartate de lysine, qui dans ce cas, cassaient sous l'action d'une traction, sans élimination du bulbe.Experience has shown that subjects with abnormal hyperhydrosis of the scalp, have a certain brittleness of the resistance of their hair, it is easily torn off with their bulb, unlike scalps treated with lysine aspartate , which in this case broke under the action of a traction, without eliminating the bulb.
I1 a été constaté que les éléments pilosébacés du cuir chevelu comportaient des canaux eccrines libérant un fluide sudoral contenant des teneurs variables d'acide lactique. I1 was found that the pilosebaceous elements of the scalp included eccrine channels releasing a sweat fluid containing variable contents of lactic acid.
Dans le cas d'hypersecrétion sudorale au niveau du cuir chevelu, il y a production élevée d'acide lactique qui provoque des dégradations biochimiques des constituants du bulbe pileux, conduisant à une perturbation de la biosynthèse de la fibre kératinique, histologiquement visible.In the case of sweat hypersecretion in the scalp, there is a high production of lactic acid which causes biochemical degradations of the constituents of the hair bulb, leading to a disturbance in the biosynthesis of the keratin fiber, which is histologically visible.
Il apparaît donc intéressant de neutraliser les effets néfastes de l'acide lactique au niveau du cuir chevelu cette action de neutralisation ne devant pas interférer dans le processus de secrétion sudorale, ni modifier en aucune façon, la fonction émonctoire et thermorégulatrice. It therefore appears interesting to neutralize the harmful effects of lactic acid on the scalp. This neutralizing action should not interfere in the process of sweat secretion, nor modify in any way, the emunctory and thermoregulatory function.
La présente invention a pour objet des compositions capillaires, destinées notamment à neutraliser l'action de l'acide lactique.The present invention relates to hair compositions, intended in particular to neutralize the action of lactic acid.
La présente invention a également pour objet de proposer une méthode de traitement cosmétique du cuir chevelu par neutralisation de l'acide lactique secrété par les glandes eccrines du cuir chevelu, par applications de compostions capillaires appropriées.Another object of the present invention is to propose a method of cosmetic treatment of the scalp by neutralization of the lactic acid secreted by the eccrine glands of the scalp, by applications of appropriate capillary compositions.
Les compositions capillaires de l'invention sont caractérisées en ce qu'elles contiennent une substance active contenant au moins un complexe résultant de l'association , en solution aqueuse ou hydroalcoolique, d'un acide aminé dicarboxylique et d'un acide aminé basique.The hair compositions of the invention are characterized in that they contain an active substance containing at least one complex resulting from the combination, in aqueous or hydroalcoholic solution, of an amino acid dicarboxylic acid and a basic amino acid.
Des compositions capillaires avantageuses de l'invention sont telles que leur substance active est constituée par l'un au moins des complexes suivants - aspartate de lysine - aspartate d'arginine - glutamate de lysine - glutamate d'arginine avantageusement l'aspartate de lysine.Advantageous hair compositions of the invention are such that their active substance consists of at least one of the following complexes - lysine aspartate - arginine aspartate - lysine glutamate - arginine glutamate advantageously lysine aspartate.
La lysine est un acide aminé basique du fait de la présence d'une fonction NH2 libre et active en position z . Une solution à 5% de lysine possede un pH voisin de 10.Lysine is a basic amino acid due to the presence of a free and active NH2 function in the z position. A 5% solution of lysine has a pH close to 10.
La réactivité de la sus-dite fonction amine permet d'obtenir des "associations" (ou complexes) avec les acides mais non des sels classiques avec élimination d'eau : tel est le cas de la lysine et de l'acide aspartique qui forme une combinaison comme les chlorhydrates d'acides aminés.The reactivity of the above-mentioned amine function makes it possible to obtain "associations" (or complexes) with acids but not conventional salts with elimination of water: this is the case of lysine and of aspartic acid which forms a combination like amino acid hydrochlorides.
L'aspartate de lysine correspond à la structure suivante
Lysine aspartate corresponds to the following structure
