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: A method of treating fibrous substrates by contacting the substrate with a fluorochemical composition comprising: a fluorochemical oligomeric component and an antisoiling component is described. The compositions provide desirable antisoiling properties, as well as oil, water and stain repellency to fibrous substrates.

Abstract: This invention relates to a treating composition containing 0.3 to 30% by weight of a fluoroaliphatic radical containing poly(oxyalkylene) compound, 0.3 to 30% by weight of an anti-soiling agent and 0 to 60% by weight of an environmentally acceptable water-miscible organic solvent and water for the use for imparting excellent water- and oil repellency, stain resistance and dry soil resistance to textiles, carpets, concrete, paper, leather and wool.

Abstract: The invention provides polymers or copolymers which are prepared by the polymerization of the reaction product of a diisocyanate with a perfluoro compound or an epichlorhydrinadduct thereof and (meth)acrylic esters of a three hydroxyl groups containing compound. Furthermore, the invention relates to fluoroacrylic monomers, a process for preparing the polymers or copolymers and a treatment agent comprising the polymers or copolymers of the invention and an environmentally acceptable solvent. Polymers and copolymers of the invention can be used for making textiles, papers, non-woven articles, leather, plastic, wood, metal, stone and cement water and oil repellent.

Abstract: Compositions for imparting water- and oil-repellency to fabrics are provided. They contain a mineral spirits solution of a fluorchemical water- and oil-repellent agent, zirconium carboxylic acid ester, and alkenyl succinic anhydride.
