Abstract
The present invention is directed to a method for preparing a W/0/W multiple emulsion by a greatly simplified, unique procedure. In the method, a mixture of oil, water, a second alkyl containing polar, protic solvent and a hydrophilic emulsifier is provided. This mixture breaks down the oil into extremely small droplets which in effect results in the solution of the oil in the mixture. This mixture containing extremely small droplets of oil is referred to herein as a 'microemulsion'. The 0/W microemulsion is then diluted with sufficient water to cause destabilization of the microemulsion and to provide a W/0/W multiple emulsion.
