Abstract
This invention concerns delivery vehicles entrapping active materials suspended in a water immiscible carrier. Methods of making these materials, preferably using a carboxymethylcellulose support martrix, are disclosed. The vehicles of the invention are especially well adapted to delivery of incompatible actives that can be entrapped separately and kept separately until release from the vehicle.
