Abstract

PURPOSE: To prepare stable liquid substance regulated having low viscosity which can be preserved for a prolonged period, by adding precipitant and a specified nonionic surfactant to an aqueous solution of fluorescent whitening dye and separating the nonionic surfactant layer contg. the fluorescent whitening dye.
CONSTITUTION: A nonionic surfactant producing two aqueous phases such as polyoxyethylene nonylphenol, polyoxyethylene polypropylene glycol and a precipitant such as NaCl, K2SO4 are added to an aqueous solution of fluorescent whitening dye of formula wherein X and Y are the same or different gps and each is hydroxy, aliph. or arom. hydroxy residual gp., amino, or aliph. arom. or heterocyclic amine residual gp, and M is H or alkali metal. The mixt. is heated at a temperature above cloud point of the nonionic surfactant for from about 10minW3hrs to produce nonionic surfactant layer contg. the fluorescent whitening dye. The layer is separated by decantation.
