Zusammenfassung:PURPOSE:To obtain a liposome and phospholipid dispersion storable stably over a long period without causing the lowering of pH of the system and applicable to drugs, quasi-drugs, cosmetics, etc., by compounding a compound selected from cepharanthine, rutin, licorice extract and kojic acid. CONSTITUTION:A liposome or phospholipid dispersion can be stabilized by compounding one or more compounds selected from cepharanthine, rutin, licorice extract (preferably oil-soluble extract) and kojic acid. The liposome and phospholipid dispersion produced by this process is resistant to the pH lowering with time and has excellent stability over a long period. The effect of liposome and phospholipid can be fully exhibited by stably compounding the above dispersion to cosmetics, etc.
