PURPOSE:To obtain an aq. dispersion of an alkylenebiscarboxylic acid amide (bisamide) having superior flowability and storage stability without increasing the amt. of an added water-soluble surfactant by using a combination of a specified water-insoluble nonionic surfactant with the water-soluble surfactant as a dispersant. CONSTITUTION:A water-soluble surfactant and a water-insoluble surfactant are added to water and then an alkylenebiscarboxylic acid amide (bisamide) is added to obtain an aq. dispersion of the bisamide. A biscarboxylic acid amide of a diamine such as ethylenebisstearamide, ethylenebishydroxystearamide, methylenebisstearamide, n-xylylenebisbenzamide or m-xylylenebisstearamide is used as the bisamide. A polyoxyethylene type nonionic surfactant contg. <=8mol added ethylene oxide or a polyol-fatty acid ester type nonionic surfactant is added as the water-insoluble surfactant by 1-10 pts.wt. per 100 pts.wt. of the bisamide. |
