Abstract
A new class of lipid vesicles having a blend of two lipids, a primary lipid and a secondary lipid, has been developed. The primary lipid, which forms the greatest proportion of lipid by weight, will not form vesicles nor preferably, even a lamellar phase, without addition of the secondary lipid. Preferably primary lipids are C.sub.12 -C.sub.18 fatty alcohols, C.sub.12 -C.sub.18 glycol monoesters, and C.sub.12 -C.sub.18 glyceryl mono- and diesters.
