Abstract:
A detergent composition comprising:(a) from 0.25% to 3%, by weight of composition of at least one cationic surfactant of the formula:R.sup.1 R.sup.2 R.sup.3 R.sup.4 N.sup.+ X.sup.-wherein R.sup.1 is a hydroxyalkyl group having no greater than 6 carbon atoms; each of R.sup.2 and R.sup.3 is independently selected from C.sub.1-4 alkyl or alkenyl; R.sup.4 is a C.sub.6-11 alkyl or alkenyl; and X is a counter ion which does not substantially exchange with hydroxide ion in a 0.5% by weight of aqueous solution of the detergent composition at 20.degree. C., so that the formation of malodorous compounds is substantially avoided;(b) an anionic surfactant which consists of a mixture of:(i) from 3% to about 40%, by weight of the composition, of at least one alkyl sulfate surfactant of the formula R.sup.5 OSO.sub.3 M; wherein R.sup.5 is C.sub.9-22 alkyl; R.sup.6 is C.sub.10-20 alkyl benzene; and M is selected from the group consisting of alkali metals, alkaline earth metals, alkanolammonium, ammonium and mixtures thereof and(ii) from 6% to about 23% by weight of the composition, of an alkyl benzene sulfonate of the formula R.sup.6 SO.sub.3 M,(c) optionally, from 0.5% to 20%, by weight of composition of at least one nonionic surfactant; and(d) an alkalinity system;wherein said composition has a pH of at least 8.0 in an aqueous solution at a concentration of 0.5% by weight.
