Abstract
An antibacterial liquid dish cleaning composition with desirable cleansing properties comprising an alkyl sulfate, a sulfonate surfactant, a solubilizer, a proton donating agent, polyethylene glycol, hydrogen peroxide, a magnesium inorganic salt and water.
Claims1
A liquid dish cleaning composition that offers antibacterial properties which comprises approximately by weight:
- (a) 16% to 30% of an alkali metal ammonium or alkaline earth metal salt of a sulfonate surfactant;
- (b) 7% to 16% of an alkali metal or ammonium salt of a sulfate surfactant;
- (c) 2 to 5% of a magnesium sulfate heptahydrate;
- (d) 0.05% to 5% of a hydrogen peroxide;
- (e) 0.1% to 5% of a proton donating agent selected from the group consisting of orthohydroxy benzoic acid, citric acid, glycolic, salicylic and lactic acid and mixtures threreof;
- (f) 1.0 to 10% of glycol ether;
- (g) 0.1 to 5% of polyethylene glycol;
- and
- (h) the balance being water, wherein the composition has a pH of 3 to 6, and has a viscosity of 100 to 1,000 cps at 25° C. using a #2 spindle at 50 rpm as measured on a Brookfield RVTDV-II viscometer wherein the composition does not contain any grease release agents, zwitterionic surfactants, alkyl polyglucoside surfactants, amine oxide surfactants, phosphoric acid 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.
