Document Type and Number:
WIPO Patent Application WO/2013/065416
Kind Code:
A1
Abstract:
Provided is an aqueous dispersion comprising dispersed particles containing lecithin and a pentacyclic triterpene having at least one substitution group selected from the group consisting of carboxyl groups and groups derived from carboxyl groups, wherein the amount of phospholipid in the lecithin is, by mass standard, within a range of twice to ten-times the amount of the pentacyclic triterpene and the volume-average particle diameter of the dispersed particles is 10 nm to 70 nm. Also provided is a method for producing the aqueous dispersion.
