Title
(EN) CATIONIC MICROPARTICLES AND USE IN THE FIELD OF COSMETOTEXTILES
(FR) MICROPARTICULES CATIONIQUES ET UTILISATION DANS LE DOMAINE DES COSMETO - TEXTILES
Abstract
(EN) One subject of the present invention is novel cationic microparticles having a diameter between 1 nm and 100 µm, the shell of which comprises: one or more polymer(s) chosen from polycaprolactone, polylactic acid, ethylcellulose, polymethyl methacrylate and an acrylate-ammonium methacrylate copolymer; and a stabilizer chosen from hexadecyltrimethylammonium bromide, benzethonium chloride, polyvinyl alcohol and aminodextran; the stabilizer/polymer weight ratio being between 0.001 and 0.5. Another subject of the present invention is a process for preparing these microparticles, and also the use thereof for the preparation of cosmetotextiles.
(FR) La présente invention a pour objet de nouvelles microparticules cationiques de diamètre compris entre 1 nm et 100 μm dont l'enveloppe comprend : un ou plusieurs polymère(s) choisi(s) parmi la polycaprolactone, l'acide polylactique, l'éthyle cellulose, le polymethylmethacrylate et un copolymère d'acrylates et d'ammonium méthacrylate; et un agent stabilisant choisi parmi le bromure d'hexadecyl trimethyl ammonium, le chlorure de benzéthonium, l'alcool polyvinylique et l'aminodextran; le rapport en poids agent stabilisant/polymère étant compris entre 0,001 et 0,5. La présente invention a également pour objet un procédé de préparation de ces microparticules, ainsi que leur utilisation pour la préparation de cosmétotextiles.
