NANOLIPOSOME USING ESTERIFIED LECITHIN AND METHOD FOR PREPARING THE SAME, AND COMPOSITION FOR PREVENTING OR TREATING SKIN DISEASES COMPRISING THE SAME

摘要

The patent describes a delivery system comprising a liposome membrane containing esterified lecithin and one or more physiologically active ingredients. The esterified lecithin is a reaction product of hydrogenated lecithin and an organic acid, preferably anhydrous malic acid or anhydrous acetic acid. If anhydrous acetic-acid is used, the esterified lecithin shows greater hydrophilicity than with anhydrous malic acid. Thus, the organic acid can be selected appropriately, depending on the relative amounts of hydrophilic or hydrophobic functional material to be added and its degree of polarity. The organic acids are also keratolytic and skin softening.
