Abstract: Aqueous compositions useful as disinfectant hard-surface cleaners comprise:(a) from about 0.03 percent to about 20 percent by weight orthobenzyl-para-chlorophenol;(b) from about 1.0 to about 2.5 parts by weight, per part by weight of Component (a), of an alkali metal salt of an alkyl naphthalene sulfonic acid or mixtures thereof;(c) from 0 to about 1.5 parts by weight, per part by weight of Component (a), of a surfactant which is different from Component (b) selected from the group consisting of(1) anionic surfactants selected from the group consisting of water soluble organic sulfonates and sulfates;(2) sulfobetaine surfactants; and(3) mixtures thereof; and(d) from about 0.02 to about 0.05 parts by weight, per combined parts by weight of Components (b) and (c), of a detergency boosting acrylic copolymer.
