Abstract
Provided is means capable of reducing the adsorptivity to plastics while suppressing a decrease in intracellular uptake efficiency in an amphiphilic compound that can be applied to long-term blood-retaining liposomes or the like as a drug carrier. The above problem can be solved by an amphiphilic compound comprising a moiety (I) including a constitutional unit (A) derived from a monomer (a) having two or more hydroxyl groups and having 2 to 10 carbon atoms constituting the side chain among the carbon atoms of the constitutional unit, and a hydrocarbon group having 8 or more carbon atoms.
