Abstract
Abstract A unit dosage form comprising one or more active ingredients and a water-soluble binder in which the water-soluble binder comprises, as a main component, a product obtained by condensing a polyoxyethylene alkyl, alkylphenyl or alkenyl ether having the following formula (I): r-o--(ch.sub.2 ch.sub.2 o).sub.n H (I) wherein R is alkyl or alkenyl having 8 to 22 carbon atoms or alkylphenyl group having 8 to 22 carbon atoms in the alkyl group, and n is an integer of from 50 to 500, with 1-epoxyethyl-3,4-epoxycyclohexane having the following formula (II): ##STR1## the molar ratio of the compound of the formula (II) to the compound of the formula (I) being in the range of from 0.05 to 2.5.
