Composition, for preparing aqueous foam containing silicon-organic graft copolymers, comprises silicon-organic graft copolymers obtained by hydrosilylation process in which an alkenyl polyether is reacted with hydroxy siloxane; and a radical grafting step, in the presence of free radical generating agent, in that at least one ethylenic unsaturated monomer is grafted to a compound containing polyether group, where: the monomer contains at least one anionic functionality of sulfonate, sulfate, phosphate and/or phosphonate groups.
