Hydrophilic modified polyrotaxane composition
The present invention aims to provide a hydrophilic modified polyrotaxane composition having excellent storage stability. The present invention relates to a hydrophilic modified polyrotaxane composition comprising: a hydrophilic modified polyrotaxane produced by modifying, with hydrophilic modifying groups, all or part of hydroxy groups on a cyclodextrin of a polyrotaxane containing the cyclodextrin, a polyethylene glycol which is included in the cavities of the cyclodextrin molecules in a skewered manner, and a capping group that is placed at each end of the polyethylene glycol and prevents dissociation of the cyclodextrin molecules from the polyethylene glycol; and a polyphenol antioxidant.
