Composition and cellulose derivative

Abstract

To provide a cellulose derivative having excellent affinity for various oil agents and a composition containing the cellulose derivative. A composition containing: a cellulose derivative and an oil agent, the cellulose derivative containing a monovalent organic group (La) that substitutes for at least some of hydrogen atoms constituting hydroxy groups in cellulose, the monovalent organic group (La) containing a hydrocarbon group having 6 or more carbons at a terminal, the monovalent organic group (La) containing no ether bond, and an average degree of substitution of the monovalent organic group (La) being 1.1 or greater. The oil agent is preferably at least one selected from the group consisting of a hydrocarbon oil, an ester oil, and a silicone oil.
