Abstract
Stable oil-in-water emulsions are prepared by mixing oil, water and an insoluble protein at high shear. By varying the amount of insoluble protein the emulsions may be made liquid, semisolid or solid. The preferred insoluble proteins are insoluble fibrous proteins such as collagen. The emulsions may be medicated with hydrophilic or hydrophobic pharmacologically active agents and are useful as or in wound dressings or ointments.
