Abstract
An improvement is described in all purpose liquid cleaning compositions and microemulsion compositions which are especially effective in the removal of oily and greasy soil and contain an anionic surfactant, an ethoxylated glycerol type compound, triethanol amine surfactant, a cosurfactant, a hydrocarbon ingredient, and water.
Claims8
A microemulsion composition comprising:
- (a) 0.1 wt. % to 5 wt. % of a mixture of ##STR7## wherein w equals one to four, and B is selected from the group consisting of hydrogen and a group represented by:
- ##STR8## 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 ##STR9## R' is selected from the group consisting of hydrogen and methyl groups;
- x, y and z have a value between 0 and 60, provided the (x+y+z) equals 2 to 100, wherein in Formula (I) the weight ratio of monoether/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;
- (b) 0.5 wt. % to 2.5 wt. % of a triethanol amine;
- (c) 0.1 wt. % to 10 wt. % of an anionic surfactant which contains sulfate or sulfonate groups;
- (d) 0.5 wt. % to 15 wt. % of a glycol ether cosurfactant;
- (e) 0.4 wt. % to 10 wt. % of a water insoluble hydrocarbon, essential oil or a perfume;
- (f) 1% to 8% of an ethoxylated/propoxylated nonionic having the formula selected from the group consisting of ##STR10## wherein R is a branched chain alkyl group having about 10 to about 16 carbon atoms, and x and y are independently numbered from 1 to 20;
- and
- (g) the balance being water.
