Title
(EN) HYDROPHILIC CYCLODEXTRIN-CONTAINING SILICONE GELS
(FR) GELS DE SILICONE HYDROPHILES CONTENANT DE LA CYCLODEXTRINE
Abstract
(EN)
Solvent-swollen crosslinked silicone gels containing covalently bonded cyclodextrin groups are prepared by hydrosilylation. The swollen gels are storage stable, compatible with water and polar solvents, and display a significant water break effect.
(FR)
La présente invention concerne des gels de silicone réticulés gonflés par solvant, contenant des groupes cyclodextrine liés de manière covalente, qui sont préparés par hydrosilylation. Les gels gonflés sont stables au stockage, compatibles avec l'eau et les solvants polaires, et présentent un effet de rupture de film d'eau significatif.
