Abstract:
1. An oil in water emulsion, said emulsion using as emulsifiers a combination consisting essentially of a primary surfactant and a secondary surfactant, said primary surfactant being a means for forming an oil in water meta stable emulsion at a physiological pH of between 6.5 and 7.8 alone or in combination with the secondary surfactant, said meta stable emulsion differentiating into an aqueous phase and an oil phase following application to the surface of the eye within 1 minute or within 5 blinks of the eye, and a secondary surfactant, differing from the primary surfactant and used in combination with the primary surfactant, said secondary surfactant being a physiologically acceptable surfactant at a pH between 6.5 and 7.8 and being a means for maintaining the emulsion stable during autoclaving at temperatures in excess of 75° C. or higher without preventing differentiation of the emulsion when applied to the surface of the eye.
