Abstract: front page image
(EN)The surface of a powder comprising a silicone resin and/or an organic powder is coated with a specific hydrophilic treating agent to render the powder hydrophilic. The hydrophilic treating agent comprises a water-soluble polyoxyalkylene glycol derivative, and the organic powder is at least one substance selected from PMMA, nylon, polyester, polystyrene, cellulose, silicone elastomer powder, silicone rubber powder, benzoguanamine, styrene divinylbenzene pinhole polymer, ethylene tetrafluoride, polyethylene powder, polypropylene powder, polyurethane powder, silk powder, a metal soap powder, starch powder, an N-acylated lysine, an organic pigment and the like. The coated powder is extremely excellent in dispersion property and dispersion stability in an aqueous dispersion medium, particularly an aqueous dispersion medium under acidic or alkaline conditions (e.g., at pH within the range of 3 to 13), and is therefore suitable for use in various types of cosmetics.
(FR)L'invention concerne une poudre comprenant une résine de silicone et/ou une poudre organique, sa surface étant enduite d'un agent de traitement hydrophile spécifique, de manière à rendre la poudre hydrophile. L'agent de traitement hydrophile comprend un dérivé de polyoxyalkylène glycol hydrosoluble, et la poudre organique consiste en au moins une substance choisie parmi le PMMA, le nylon, le polyester, le polystyrène, la cellulose, la poudre d'élastomère de silicone, la poudre de caoutchouc de silicone, la benzoguanamine, le polymère styrène-divinylbenzène-huile de pin, le tétrafluorure d'éthylène, la poudre de polyéthylène, la poudre de polypropylène, la poudre de polyuréthanne, la poudre de soie, la poudre de savon métallique, la poudre d'amidon, la lysine N-acétylée, les pigments organiques et analogue. La poudre enduite présente d'excellentes propriétés de dispersion et une excellente stabilité de dispersion en milieu aqueux, notamment en conditions acides ou alcalines (par exemple, pour un pH compris entre 3 et 13), et est donc adaptée à une utilisation dans divers types de produits cosmétiques.
