Abstract

A method for preparing a microemulsion is disclosed which employs a method based upon identification of the phase behavior of a plurality of components comprising the microemulsion. Further disclosed is a microemulsion composition comprising a first component, coupling agent, and surfactant.

Claims (6)

1. A composition of matter comprising benzyl alcohol, DOSS and NPG that forms a stable microemulsion when diluted with up to but less than 100 weight percent water.

2. A composition comprising benzyl alcohol, DOSS, NPG, and water that does not scatter non-directional light.

3. A composition comprising benzyl alcohol, DOSS, NPG, and water that is a microemulsion.

4. A composition comprising benzyl alcohol, DOSS, NPG, and water that does not scatter non-directional light but exhibits Tyndall scattering when viewed at an angle with respect to the collimated light beam.

5. The composition of claim 4 wherein the viewing angle is from about 20 degrees to about 160 degrees with respect to the collimated light beam.

6. The composition of claim 2 comprising from 10 to 90 weight percent water.
