Publication number: 20040185068Abstract: Preparation of self-emulsifying compositions which are prepared without mechanical homogenization is described. These self-emulsifying compositions are prepared using one or two surfactants. This provides the advantage of a low weight ratio of emulsifying component to oil component and fewer chemical toxicity concerns, resulting in comfort and safety advantages over emulsions employing more than two emulsifiers. Consequently, the self-emulsifying compositions described are ideally suited for ophthalmic applications including administration of therapeutics to the eye. Self-emulsifying compositions prepared by the disclosed method are described.Type: ApplicationFiled: March 18, 2003Publication date: September 23, 2004Inventors: Zhi-Jian Yu, Stan Huth
