    摘要: A composition is disclosed containing nonesterified fatty acids having 14-18 carbon atoms, monoglycerides which are monoesters of glycerol and fatty acids having 14-18 carbon atoms, lysophosphatidylcholine in which the fatty acid moiety has 14-18 carbon atoms and bicarbonate. The compositions can optionally also contain bile salts. These compositions form submicron size colloidal particles and can act as vehicles for transporting orally administered drugs, sources of calories in the form of readily absorbable fats and as particles for topical application to the skin. A method of making these particles is also described.
