Abstract

PURPOSE: To prepare the highly concentrated title composituion of good stability with time, by dispersion of a water-insoluble fluorescent brightener in water using a diglycerol deriuatiue and a water-soluble polymer.
CONSTITUTION: The objective composituin can be prepared by dispersion of the following mixture in water: Said mixture comprising (1) 1-30wt.% of a water-in- soluble fluorescent brightener, (2) 1-70wt.% of a diglycoral derivative of formula (R1 and R2 are each H, 1-4C alkyl, or acyl), (3) 0.2W10wt.% of a water-soluble poymer such as carboxgmethyl cellulqse, polyvinyl alcohol, etc. and, if necessary, (4) 0.5W2wt.% of a nonionic surjactant or a tamol type auionic surfactant. All the wt.% values are besed on the final composition.
EFFECT: Free from flocculation and/or sedimentation of the fluorescent brightener during storage, also from degrodation of the brightening effect resulting from the coarse particle development.
