    • A composition comprising a self-emulsifiable or self-dispersible aqueous solution or dispersion of at least one urea linkage-containing alkoxypolyoxyalkylene fluorocarbamate prepared by contacting (a) at least one polyisocyanate which contains at least three isocyanate groups per molecule, (b) at least one fluorochemical reagent of the formula F(CF2)aCH2CH2OH, wherein a is 4, 6, or 8, or mixtures thereof, provided that a is a maximum of 50% of 8, and (c) at least one hydrophilic, water-solvatable reagent which contains per molecule a single functional group which has at least one reactive Zerewitinoff hydrogen atom, and thereafter with (d) water, the equivalent weight of the polyisocyanate and the reagents (b) and (c) being such that the reagents react with 55% to 95% of the isocyanate groups, and water reacts with all of the remaining isocyanate groups, the composition imparting durable hydrophilicity and stain release properties to a substrate treated therewith is disclosed.
