Title
(EN) HYDROPHILIC SILICA/POLYMER BLEND
(FR) MÉLANGE POLYMÈRE/SILICE HYDROPHILE
Abstract
(EN)
A hydrophilic silica/polymer blend is provided comprising (a) a hydrophilic silica powder; and (b) a thickening polymer powder, comprising (i) structural units of C4‑8 alkyl (meth)acrylate monomer; (ii) structural units of (meth)acrylic acid monomer; (iii) structural units of (methoxy) poly(ethylene glycol) (meth)acrylate monomer; and (iv) structural units of multiethylenically unsaturated monomer; wherein the weight ratio of hydrophilic silica powder to thickening polymer powder in the hydrophilic silica/polymer blend is 1:9 to 9:1. Also provided are personal care compositions containing same and methods of using same.
(FR)
L'invention concerne un mélange polymère/silice hydrophile comprenant (a) une poudre de silice hydrophile ; et (b) une poudre de polymère épaississant, comprenant (i) des unités structurelles de monomère (méth)acrylate d'alkyle en C4‑8 ; (ii) des unités structurelles de monomère d'acide (méth)acrylique ; (iii) des unités structurelles de monomère de (méthoxy) poly(éthylène glycol) (méth)acrylate ; et (iv) des unités structurelles de monomère non saturé en multiéthylène, ; le rapport pondéral entre la poudre de silice hydrophile et la poudre de polymère épaississant du mélange polymère/silice hydrophile étant de 1:9 à 9:1. L'invention concerne également des compositions de soins d'hygiène corporelle le contenant et des méthodes d'utilisation associées.
