Abstract
Abstract Aqueous compositions useful as disinfectant hard-surface and general purpose household cleaners comprise: (a) from about 0.03 percent to about 20 percent by weight ortho-benzyl-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 about 0.03 to about 1.5 parts by weight, per part by weight of Component (a), of a sulfobetaine surfactant; (d) from about 0.2 to about 0.5 parts by weight, per part by weight of Component (c), of an anionic surfactant which is a C10 to C18 alkyl sulfate or mixtures thereof; (e) from about 0.02 to about 0.05 parts by weight, per combined parts by weight of Components (b), (c) and (d), of a detergency boosting acrylic copolymer.
