Abstract:
An antibacterial liquid dish cleaning composition which comprises approximately by weight:(a) 10% to 14% of a sodium salt of a C8-C16 linear alkyl benzene sulfonate surfactant; (b) 10% to 14% of a magnesium salt of a C8-C16 linear alkyl benzene sulfonate surfactant; (c) 10% to 14% of an ammonium or sodium salt of an ethoxylated C8-C18 alkyl ether sulfate surfactant; (d) 0.5% to 5% of a zwitterionic surfactant; (e) 0.5% to 5% of a hydroxy containing organic acid selected from the group consisting of salicylic acid, lactic acid, glycolic acid, citric acid, acetic acid, and mixtures thereof; (f) 0.1% to 7% of polyethylene glycol; of a hydroxy containing organic acid selected from the group consisting of salicylic acid, lactic acid, glycolic acid, citric acid, acetic acid, and mixtures thereof; (g) 1-10% of a solubilizing agent; and (h) the balance being water, wherein the composition has a pH of 3 to 4 and has a viscosity of 100 to 1,000 cps at 25Â° C. using a #21 spindle at 20 rpm as measured on a Brookfield RVTDV-II viscometer, wherein the composition does not contain any choline, chloride, ammonium or alkaline earth carbonate, amine oxide surfactants, guanidine derivates, alkoxylalkyl amines and alkyleneamines C3-C7 alkyl and alkenyl monobasic and dibasic acids which do not contain a hydroxy group, boric acid, phosphoric acid, ethoxylated nonionic surfactants, amino alkylene phosphonic acid and alkyl polyglucoside surfactants and the composition is pourable and not a gel and has a complex viscosity at 1 radsâˆ’1 of less than 0.4 Pascal seconds.
