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.
