Donald F H Wallach: Paucilamellar lipid vesicles. Micro Pak, Lahive & Cockfield, March 27, 1990: US04911928 (103 worldwide citation)

A new method of producing paucilamellar lipid vesicles has been developed. The vesicles are made of non-phospholipid surfactants. The paucilamellar lipid vesicles have 2-8 lipid bilayers surrounding a central cavity which may be filled with either an aqueous-based solution or an oil or wax.

Disclosed are hybrid paucilamellar lipid vesicles containing a phospho- or glycolipid and a nonionic, anionic, or zwitterionic surfactant in the lipid bilayers. The paucilamellar vesicles may have either an aqueous or oil-filled central cavity. A method of manufacture for these vesicles is also disc ...

The present invention relates to oil-in-water emulsion compositions useful for imparting an artificial tan to human skin. These emulsions contain paucilamellar lipid vesicles, i.e. vesicles comprising several concentric lipid bilayers, encapsulating an aqueous dihydroxyacetone solution. The vesicles ...

Donald F H Wallach: Paucilamellar lipid vesicles using charge-localized, single chain, nonphospholipid surfactants. Micro Vesicular Systems, Lahine & Cockfield, July 16, 1991: US05032457 (26 worldwide citation)

Disclosed are paucilamellar lipid vesicles made of single chain nonphospholipid anionic or zwitterionic surfactants and a method of their manufacture. The preferred vesicle forming materials are single chain sarcosinamides having 12-20 carbon chains and single chain betaines. The vesicles are formed ...

Donald F H Wallach, Rajiv Mathur: Method of making oil filled paucilamellar lipid vesicles. Micro Vesicular Systems, November 3, 1992: US05160669 (21 worldwide citation)

A new "cold-loading" technique for filling the amorphous central cavity of paucilamellar lipid vesicles with a water immiscible material has been developed. Preformed, substantially aqueous filled paucilamellar lipid vesicles are mixed with the water immiscible material to be encapsulated under inte ...
