Abstract
Abstract The invention relates to a stable composition for treating textile substrates which contains at least (a) an organic solvent which is sparingly soluble to insoluble in water and in which component (b) is dissolved and component (c) is dissolved or dispersed, (b) a vehicle for component (c) which is sparingly soluble to insoluble in water, and (c) a finishing agent which is sparingly soluble to insolube in water and which is soluble or dispersible in the vehicle (b). In addition to components (a), (b) and (c), the composition of the invention may also contain (d) a solid carboxylic acid which is sparingly soluble in water, and preferably soluble in the solvent (a), and/or (e) a polar organic solvent as well as further additives or assistants. The novel composition, which preferably contains fluorescent whitening agents as finishing agents, is used in particular for whitening manmade textiles, especially made-up goods such as curtains or underwear.
