Part or all may be substituted with a hydroxyl group (A) such as (A), and an oxycarbonyl group (—COO— or —O CO-) or a linear or branched alkyl group, alkenyl group or acyl group having 10 to 43 carbon atoms into which an ether bond may be inserted (the hydrogen atom of the hydroxyl group of the substituent (A) is further substituted. And a polysaccharide derivative which may be substituted.
