Compositions for removing finishing agents containing silicone oil, aqueous dispersions prepared therefrom and their use A b s t r a c t Compositions for removing finishing agents containing silicone oil contain, as essential component, a surfactant carrying cationic groups on the surfactant framework structure; these surfactants can be amphoteric surfactants or betaine surfactants. These compositions can furthermore contain acids, non-ionic surfactants, water-soluble non-ionic polymers and solvents (free of halogenated hydrocarbons). Aqueous dispersions in the form of concentrates (as commercial products) or in the form of dilute liquors directly usable in the washing process can be prepared from the compositions. The compositions are used for removing finishing agents containing silicone oil from textile substrates, in particular from substrates containing elastane fibres; to this end, the compositions are eventually used in the form of liquors usable in the washing process.
