Claims5
A microemulsion cleaning composition comprising:
- (a) 0.1 wt. % to 8 wt. % of an anionic selected from the group consisting of sulfonated surfactants and sulfated surfactants;
- (b) 0.5% to 6% of a mixture of:
- wherein w equals one, and B is selected from the group consisting of hydrogen and a group represented by:
- wherein R is selected from the group consisting of alkyl group having 6 to 22 carbon atoms, and alkenyl groups having 6 to 22 carbon atoms, wherein at least one of the B groups is represented by said
- R′ is selected from the group consisting of hydrogen and methyl groups;
- x, y and z have a value between 0 and 60, provided that (x+y+z) equals 2 to 100, wherein in Formula (I) the weight ratio of monoester / diester / triester is 40 to 90/5 to 35/1 to 20, wherein the weight ratio of Formula (I) and Formula (II) is a value between 3 and 0.02;
- (c) 0.5% to 8% of a short chain amphiphiles formed from the condensation product of an alkanol, ethylene oxide and propylene oxide;
- (d) 0.05% to 2% of a fatty acid;
- (e) 0.25% to 6% of magnesium sulfate;
- (f) 0.1 to 5 wt. % of a water insoluble hydrocarbon, essential oil or a perfume;
- (g) 0.001% to 1.0% of at least one preservative selected from the group consisting of 1,3 dimethylol dimethyl hydantoin, isothiazolones mixtures and 5-bromo-5-nitro-1,3-dioxane;
- (h) 0.25% to 1.5% of a preservative potentiator which is imino disuccinate-sodium salt;
- and
- (i) the balance being water.
