There are provided: a composition for forming a water repellent film that can form a water repellent film not only excellent in water repellency but also excellent in abrasion resistance, particularly in abrasion resistance evaluated under close-to-actual-use conditions where a light resistance test is combined; a water repellent film formed by using the composition for forming a water repellent film; a substrate with a water repellent film including the water repellent film provided on at least part of a substrate; and an article including the substrate with a water repellent film. The composition for forming a water repellent film contains, at a predetermined quantitative ratio of a hydrolyzable silane compound (1) having a perfluoroalkyl group and having no ether bond; and a compound (21) that has a poly(oxyfluoroalkylene) group and a plurality of hydrolyzable silyl groups with a specific structure and that has a number average molecular weight of 3000 or more.

Copolymers are formed of monomers of poly(dimethylsiloxane) and poly(alkylene oxide) of the following formula: A.sub.x-XCH.sub.2CH.sub.2—[B.sub.yC.sub.z].sub.n—X-A.sub.x. In the formula, each X independently represents a —CH.sub.2— group or an oxygen atom, A represents a polydimethylsiloxane derivative, B represents a polyethylene glycol unit, C represents a polypropylene glycol unit, x and n independently represent an integer from 1 to 150, and y and z independently represent an integer from 0 to 150. The copolymers can be used as emulsifiers in personal care compositions.
