Abstract
The invention relates to the use of a cosmetic composition, in aqueous media or water and a solvent, having a non-phosphated, cationic, gelling molecular composition with a molecular weight less than 2,000 g/mol and comprising at least two amide groups, one asymmetric carbon and one fatty chain with at least eight carbon atoms.
Description
AMIDE CATIONIQUE HYDROGELIFIANT EN COSMETIQUE CATIONIC HYDROGELIFYING AMIDE IN COSMETICS
L'invention a pour objet l'utilisation, en cosmétique, d'amides cationiques hydrogélifiants.The subject of the invention is the use, in cosmetics, of cationic hydrogelling amides.
On connaît des compositions épaissies, notamment des gels capillaires, qui sont généralement appliquées sur les cheveux avant de mettre en forme la coiffure. Pour mettre en forme et fixer la coiffure, on effectue ensuite un brushing ou une mise en plis.Thickened compositions are known, in particular hair gels, which are generally applied to the hair before shaping the hairstyle. To shape and fix the hairstyle, we then do a brushing or styling.
Ces compositions épaissies, notamment ces gels, peuvent contenir des résines polymères.These thickened compositions, in particular these gels, can contain polymer resins.
Toutefois, elles présentent souvent l'inconvénient d'altérer les propriétés cosmétiques des cheveux. Ainsi, les cheveux peuvent devenir rêches, difficiles à démêler, perdre leur toucher et leur aspect agréables ou encore manquer de corps. On recherche donc de telles compositions cosmétiques capillaires procurant de bonnes propriétés cosmétiques, notamment en terme de démêlage, de douceur et de toucher.However, they often have the drawback of altering the cosmetic properties of the hair. Thus, the hair can become coarse, difficult to disentangle, lose its touch and its pleasant appearance or even lack body. We are therefore looking for such hair cosmetic compositions providing good cosmetic properties, in particular in terms of detangling, softness and feel.
En outre, les compositions cosmétiques capillaires épaissies présentent également l'inconvénient majeur de donner lieu à un effet de poudrage. Au sens de la présente invention, on entend par «poudrage », l'aptitude du matériau obtenu par séchage de la composition capillaire à former une poudre après son application sur les cheveux.In addition, thickened hair cosmetic compositions also have the major drawback of giving rise to a dusting effect. For the purposes of the present invention, the term "dusting" means the ability of the material obtained by drying the hair composition to form a powder after its application to the hair.
Les milieux cosmétiques aqueux sont, en général, gélifiés par des polymères hydrophiles réticulés. Il est difficile de réaliser des gels cosmétiques aqueux qui auraient, après le séchage sur les cheveux, une bonne résistance à un climat humide.The aqueous cosmetic media are, in general, gelled by crosslinked hydrophilic polymers. It is difficult to produce aqueous cosmetic gels which, after drying on the hair, have good resistance to a humid climate.
Il existe donc un besoin de trouver des compositions cosmétiques, notamment capillaires épaissies, notamment des gels capillaires, qui ne présentent pas l'ensemble des inconvénients indiqués ci-dessus, et qui, en particulier résistent à un climat humide.There is therefore a need to find cosmetic compositions, in particular thickened capillaries, in particular hair gels, which do not have all of the drawbacks indicated above, and which, in particular withstand a humid climate.
Pour résoudre ce problème, l'invention propose l'utilisation en cosmétique de petites molécules chirales à fonctions amides et à chaînes grasses, contenant des
fonctions ioniques. Ces molécules sont décrites dans la littérature, et notamment dans les publications suivantes: Chemistry Letters 2002, (7), 704-705; New Journal of Chemistry 2002, 26 (7), 817-818; Chemical Communications (Cambridge, United Kingdom) 2002, (8), 884-885.To solve this problem, the invention proposes the use in cosmetics of small chiral molecules with amide functions and with fatty chains, containing ionic functions. These molecules are described in the literature, and in particular in the following publications: Chemistry Letters 2002, (7), 704-705; New Journal of Chemistry 2002, 26 (7), 817-818; Chemical Communications (Cambridge, United Kingdom) 2002, (8), 884-885.
La Demanderesse a maintenant découvert qu'après le séchage sur les cheveux, ces gels forment des dépôts ayant une excellente tenue à l'humidité.The Applicant has now discovered that after drying on the hair, these gels form deposits having excellent resistance to humidity.
L'invention a pour objet l'utilisation dans une composition cosmétique, en milieu aqueux ou eau+solvant, d'un composé moléculaire épaississant ionique non phosphore, de poids moléculaire inférieur à 2 000 g/mol et comprenant au moins:The subject of the invention is the use in a cosmetic composition, in aqueous medium or water + solvent, of a non-phosphorus ionic thickening molecular compound, of molecular weight less than 2,000 g / mol and comprising at least:
- deux groupements amide,- two amide groups,
- un carbone asymétrique,- an asymmetric carbon,
- une chaîne grasse comportant au moins huit carbones.- a fatty chain comprising at least eight carbons.
Par "composé moléculaire", on entend, au sens de la présente invention, tout composé dont le squelette ne résulte pas d'une polymérisation. Ceci n'exclut pas que le composé puisse contenir un ou plusieurs groupement polyoxyalkylénés ou polyoxyglycérolés.By "molecular compound" is meant, within the meaning of the present invention, any compound whose backbone does not result from a polymerization. This does not exclude that the compound may contain one or more polyoxyalkylenated or polyoxyglycerolated groups.
Par "molécule cationique", on entend, au sens de la présente invention, une molécule comprenant au moins un atome d'azote quaternisé.By "cationic molecule" is meant, within the meaning of the present invention, a molecule comprising at least one quaternized nitrogen atom.

Il peut, par contre, être soluble, à pH acide ou alcalin.Preferably, the composition forms a film after drying. In a preferred mode, the film is insoluble in pure water, at room temperature. On the other hand, it can be soluble, at acidic or alkaline pH.
