Polyrotaxane composition
The present invention aims to provide a polyrotaxane composition having excellent storage stability. The present invention relates to a polyrotaxane composition comprising: a polyrotaxane containing a 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.
