Abstract
An antibacterial liquid dish cleaning composition with desirable cleansing and de-staining properties comprising a C8-18 ethoxylated alkyl ether sulfate, two anionic surfactant, a betaine surfactant, a hydroxy containing organic acid, polyethylene glycol, hydrogen peroxide and water.
Claims2
A liquid dish cleaning composition that offers antibacterial properties, 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;
- (f) 0.5% to 10% of hydrogen peroxide;
- (g) 0.1% to 7% of polyethylene glycol;
- 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 25° C. using a #21 spindle at 20 rpm as measured on a Brookfield RVTDV-II viscometer, wherein the composition does not contain any grease release agents, a nitrogenous buffer, 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 rads−1 of less than 0.4 Pascal seconds.
