A water-repellent composition capable of imparting both favorable water-repellency and favorable slip resistance to a textile product is provided by A water-repellent composition comprising a non-fluorine copolymer (A) comprising a repeating unit derived from a hydrophobic monomer (a1) having a hydrocarbon group having 2 to 40 carbon atoms, and a repeating unit derived from at least one chloride monomer (a2) selected from the group consisting of vinyl chloride and vinylidene chloride, wherein in the non-fluorine copolymer (A), an amount of repeating units derived from the monomer (a2) is 1 to 9% by weight based on a sum of an amount of repeating units derived from the monomer (a1) and the amount of repeating units derived from the monomer (a2).
