PROBLEM TO BE SOLVED: To provide a non-fluorine composition which provides water repellency and, in some cases, stain releasing property to a fabric, which has the same performance result as a fluorination treatment agent. SOLUTION: The present invention is an aqueous composition comprising at least one hydrophobic compound having a bond of at least one Formula I. -NHC (O) -X- (I) The bond of formula (I) constitutes 30-100 mol% of the total urethane bond in the hydrophobic compound. During the ceremony X is -R 1 ; -C (O) R 1 ; or-(CH 2 CH 2 O) n (CH (CH 3 ) CH 2 O) m C (O) R 1 with at least two residues. Residues of substituted cyclic or acyclic sugar alcohols, During the ceremony Each n is independently 0 to 20 and Each m is independently 0 to 20 and m + n is greater than 0, An aqueous composition in which each R 1 is a linear or branched alkyl group independently having 5 to 29 carbons.
