Claims
- 1. A microemulsion composition comprising:(a) 0.1 wt. % to 10 wt. % of at least one nonionic surfactant; (b) 0.1 wt. % to 20 wt. % of an anionic surfactant; (c) 0.1 wt. % to 15 wt. % of at least one cosurfactant; (d) 0.1 wt. % to 10 wt. % of a water insoluble hydrocarbon, essential oil or a perfume; (e) 0.1 wt. % to 6 wt. % of a hydroxy aliphatic acid; (f) 0.1 wt % to 5.0 wt % of salicylic acid; and (g) a fatty acid with 8 to 22 carbon atoms; and (h) the balance being water.
- 2. The microemulsion composition of claim 1 which further contains a salt of a multivalent metal cation in an amount sufficient to provide from 0.5 to 1.5 equivalents of said cation per equivalent of said anionic detergent.
- 3. The microemulsion composition of claim 2 wherein the multivalent metal cation is magnesium or aluminium.
- 4. The microemulsion composition of claim 2, wherein said composition contains 0.7 to 1.4 equivalents of said cation per equivalent of anionic detergent.
- 5. The microemulsion composition of claim 3 wherein said multivalent salt is magnesium oxide or magnesium sulfate.
- 6. The microemulsion composition of claim 1 wherein the cosurfactant is a water soluble glycol ether.
- 7. The microemulsion composition of claim 6 wherein the glycol ether is selected from the group consisting of ethylene glycol monobutylether, diethylene glycol monobutyl ether, triethylene glycol monobutylether, poly-propylene glycol having an average molecular weight of from 200 to 1,000 and propylene glycol tert.butyl ether, mono-, di-, tri-propylene glycol monobutyl ether.
- 8. The microemulsion composition of claim 6 wherein the glycol ether is ethylene glycol monobutyl ether or diethylene glycol monobutyl ether.
- 9. The composition of claim 7, wherein said hydroxy aliphatic acid is citric acid, salicylic acid or lactic acid or mixtures thereof.
