Patent number: 11655434Abstract: The present invention relates a composition capable of enhancing cleaning properties of a soil during cleaning by treating an object. The composition is a composition containing a modified hydroxyalkyl cellulose and at least one selected from an anionic surfactant and a nonionic surfactant, the modified hydroxyalkyl cellulose being one in which a cationic group and a hydrophobic group represented by the formula (1) are bound to a group resulting from eliminating a hydrogen atom from a hydroxy group of a hydroxyalkyl cellulose. *—Z—R1??(1) wherein, Z represents a single bond or a hydrocarbon group having an oxygen atom; R1 represents a hydrocarbon group having 2 or more carbon atoms; and * represents a binding position to a group resulting from eliminating a hydrogen atom from a hydroxy group of a hydroxyalkyl cellulose.Type: GrantFiled: December 5, 2018Date of Patent: May 23, 2023Assignee: KAO CORPORATIONInventors: Takanori Saito, Yoichiro Imori, Akihiro Koyama, Yukiko Yamawaki
