Clear aqueous compositions comprising water, a hydrophobic organic compound, and from about 2 to about 50 wt.% of a solubilizer are disclosed. The solubilizer is an alkali metal or alkaline earth metal salt of a monoester of a saturated C6-C20 alcohol and a saturated dicarboxylic acid. The monoester salts are remarkably effective for solubilizing a wide variety of hydrophobic organic compounds in water to provide aqueous compositions that have excellent stability and outstanding clarity. The compositions are valuable for the cosmetic, agrochemical, coatings, pharmaceutical, and flavor & fragrance industries.
La présente invention concerne des solutions aqueuses contenant de l'eau, un composé organique hydrophobe et de 2 à environ 50 wt.% d'un solubilisant. Le solubilisant est un métal alkalin ou le sel de métal alcalino-terreux d'un monoester d'alcool C6-C20 saturé et d'un acide dicarboxylique saturé. Les sels monoesters sont remarquablement efficaces pour dissoudre dans l'eau une grande variété de composés organiques hydrophobes afin de produire des compositions aqueuses caractérisées par une excellente stabilité et une remarquable clarté. Ces compositions sont d'une grande valeur dans l'industrie cosmétique, agrochimique, des revêtements, l'industrie pharmaceutique et celle des arômes et fragrances.
