This aggregation inhibitory agent contains, as an aggregation inhibitory component, at least one selected from the group consisting of polyoxyethylene cetyl ether, polyoxyethylene sorbitan fatty acid esters, and polyoxyethylene polyoxypropylene glycol having an average molecular weight of 3000-13000. The present invention can prevent aggregation of a poorly water-soluble agent caused by a silicone oil within a container having an inner wall treated with the silicone oil. |
