    Abstract: The present invention provides an aqueous composition comprising (i) a fluorochemical compound and (ii) an ester derivative of an alpha-hydroxy acid, the ester derivative having a melting point of not more than 35° C. and a water solubility of not more than 10% by weight at 25° C. The fluorochemical compound is typically dispersed or emulsified in the aqueous composition. The aqueous compositions may provide such advantages as providing good oil- and/or water repellency properties to a substrate upon application at ambient conditions, without the need for a heat treatment. Thus, the aqueous compositions may be used to provide oil- and/or water repellency properties to a substrate such as for example a fibrous substrate, e.g., leather or textile. In particular, repellency properties comparable to those achieved with a heat treatment step may be achieved.

    Abstract translation: 本发明提供一种水性组合物,其包含(i)含氟化合物和(ii)α-羟基酸的酯衍生物,所述酯衍生物的熔点不超过35℃,水溶性不大于 在25℃下为10重量%以下。含氟化合物通常在水性组合物中分散或乳化。 含水组合物可以提供这样的优点,例如在环境条件下施用时向基材提供良好的油和/或拒水性质,而不需要热处理。 因此,水性组合物可用于向基材例如纤维基材例如皮革或纺织品提供油和/或拒水性能。 特别地,可以实现与通过热处理步骤实现的排斥性能相当的排斥性能。
