Abstract: A dye composition contains as indispensable ingredients a water-insoluble dye and 10-150% by weight, based on the dye, of a nonionic surfactant of the general formula:HO--C.sub.2 H.sub.4 O).sub.l (C.sub.3 H.sub.6 O).sub.m (C.sub.2 H.sub.4 O).sub.n Hwherein l, m and n each represent an integer of one or more l+m+n being in the range of 100-350 and (l+n)/m being two or more.

Abstract: A detergent composition which has a low irritation effect to human skin containing as an active surfactant component one or a mixture of compounds having the formulas ##STR1## wherein R is saturated or unsaturated hydrocarbon having 10 to 16 carbon atoms, X.sub.1 and X.sub.3 are hydrogen, alkali metal, ammonium, alkylammonium or substituted alkylammonium, and X.sub.2 is alkali metal, ammonium, alkylammonium or substituted alkylammonium, with the provisos that both X.sub.1 and X.sub.2 are not alkali metal and that when R has an average carbon atom number of 10, X.sub.1 is hydrogen, and wherein the weight ratio of the formula (1) compound(s) : formula (2) compound(s) is from 100:0 to 80:20.
