Abstract
A topical delivery composition which employs a multivesicular emulsion in combination with a pharmaceutically/pharmacologically active agent is disclosed. The multivesicular emulsion is formed from a quaternary amine salt emulsifier such as behentrimonium methosulfate. The emulsion is multi-lamellar which is a series of concentric spheres or vesiculars of oil and water phase that can be seen microscopically. As a result, the active is time released over a sustained period rather than spike released as is common with most topicals.
