Zusammenfassung: | The invention relates to a process for preparing a cosmetic article that is adaptable to the shape of the face, neck and/or neckline, comprising a nonwoven support sheet, made of non-synthetic fibres, on which is immobilized, in the dry state and in a non-covalent manner, at least one hydrophilic cosmetic active agent intended to exert a specific action on the skin, characterized in that it comprises at least the steps consisting in: i) providing said active agent in a dry, pulverulent form; ii) providing at least one hydrophilic, in particular water-soluble, binder with a melting point ranging from 55°C to 140°C in a dry, pulverulent form; iii) forming, on one face of said sheet of porous nonwoven support, a deposit, at least partially in depth, of a dry, pulverulent mixture of at least said hydrophilic cosmetic active agent with at least said hydrophilic binder; iv) exposing said deposit to a calendering operation performed at a temperature and pressure that are conducive to the melting of said hydrophilic binder but inactive with respect to said cosmetic active agent and of said fibres of said support sheet, and v) recovering said support sheet charged with hydrophilic cosmetic active agent. The invention also relates to a cosmetic article that is adaptable to the shape of the face, neck and/or neckline, preferentially obtained via the preceding process, and to the use of such an article.
L'invention concerne un procédé de préparation d'un article cosmétique adaptable à la forme du visage, du cou et/ou du décolleté, comprenant une feuille support non tissée, en fibres non synthétiques, sur laquelle est immobilisé, à l'état sec et de manière non covalente, au moins un agent actif cosmétique hydrophile destiné à exercer une action spécifique sur la peau, caractérisé en ce qu'il comprend au moins les étapes suivantes : i) mise à disposition dudit agent actif sous forme sèche et pulvérulente ; ii) mise à disposition d'au moins un liant hydrophile, notamment hydrosoluble, dont le point de fusion est compris entre 55 et 140 °C, sous forme sèche et pulvérulente ; iii) constitution, sur une face de ladite feuille de support poreux non tissé, d'un dépôt, au moins partiellement en profondeur, d'un mélange sec et pulvérulent d'au moins ledit agent actif cosmétique hydrophile avec au moins ledit liant hydrophile ; iv) exposition dudit dépôt à une opération de calandrage réalisée à une température et une pression propices à la fusion dudit liant hydrophile mais inac |
