Abstract

Abstract A stable composition for treating textile substrates, which composition comprises at least (a) an organic solvent which is sparingly soluble or insoluble in water and in which component (b) is dissolved and components (c) and (d) are dissolved or dispersed, (b) a vehicle for component (c) which is sparingly soluble or insoluble in water, (c) a finishing agent which is sparingly soluble or insoluble in water and which is soluble or dispersible in the vehicle (b), and (d) a water-soluble acid having a pK value greater than 1 and optionally in addition (e) a solid carboxylic acid which is sparingly soluble in water, (f) a polar solvent and/or further additives or assistants, e.g. surfactants or chelating agents. The novel composition, which preferably contains fluorescent whitening agents as finishing agents, is used in particular for whitening synthetic fibre materials, especially finished goods such as curtains or underwear, in acid medium.
