Title
(EN) HYGIENE ARTICLE COMPRISING SOLID EMULSION AND METHOD OF MANUFACTURE
(FR) ARTICLE D'HYGIÈNE COMPRENANT UNE ÉMULSION SOLIDE ET PROCÉDÉ DE FABRICATION
Abstract
(EN)
A hygiene article comprising one or more layers, which article comprises a solid emulsion, which solid emulsion comprises a matrix of solid continuous phase and a dispersed oil phase, wherein the solid continuous phase comprises cellulose derivatives (CD), nanocellulose and the dispersed oil phase is an oil containing composition. The cellulose derivatives (CD) are preferably chosen from carboxymethyl cellulose (CMC), hydroxyethyl cellulose (HEC), ethyl hydroxyethyl cellulose (EHEC), or hydroxylpropyl methyl cellulose (HPMC), preferably CMC or HEC, or combinations of two or more of these cellulose derivatives. Methods of manufacture of the hygiene article comprising the steps of preparing a film, foam, or particulate comprising the solid emulsion, and incorporating it into a hygiene article, or by applying a fluid emulsion onto a web of fibrous material, and drying the fluid emulsion until 50-100wt% of the water comprised in the fluid emulsion has evaporated, and incorporating the web of fibrous material into a hygiene article, or by applying a fluid emulsion onto a web of fibrous material already incorporated in a hygiene article and drying the emulsion.
(FR)
La présente invention concerne un article d'hygiène comprenant une ou plusieurs couches, ledit article comprenant une émulsion solide, laquelle émulsion solide comprend une matrice à phase continue solide et une phase huileuse dispersée, la phase continue solide comprenant des dérivés de cellulose (CD), de la nanocellulose et la phase huileuse dispersée étant une composition contenant de l'huile. Les dérivés de cellulose (CD) sont de préférence choisis parmi la carboxyméthylcellulose (CMC), l'hydroxyéthylcellulose (HEC), l'éthylhydroxyéthylcellulose (EHEC), ou l'hydroxylpropylméthylcellulose (HPMC), de préférence la CMC ou l'HEC, ou des combinaisons d'au moins deux de ces dérivés de cellulose. L'invention porte également sur des procédés de fabrication de l'article d'hygiène comprenant les étapes consistant à préparer un film, une mousse ou des particules comprenant l'émulsion solide, et à l'incorporer dans un article d'hygiène, ou par application d'une émulsion fluide sur une bande de matériau fibreux, et séchage de l'émulsion fluide jusqu'à ce que 50 à 100 % en poids de l'eau contenue dans l'émulsion fluide s'évaporent, et incorporation de la bande de matière fibreuse dans un article d'hygiène, ou par application d'une émulsion fluide sur une bande de matière fibreuse déjà incorporée dans un article d'hygiène et séchage de l'émulsion.
