Abstract: 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.

Abstract: The present invention relates to a soil release agent capable of enhancing cleaning properties for removing a soil during cleaning through treatment of an object, and a soil release composition containing the soil release agent. The soil release agent is a soil release agent including a modified hydroxyalkyl cellulose in which a hydroxyalkyl cellulose is bound to at least one selected from a cationic group and a hydrophobic group including a hydrocarbon group having 4 or more carbon atoms.

Abstract: The present invention relates to a fabric treatment composition capable of enhancing cleaning properties of a soil during cleaning through treatment of a fabric to be treated and a method for treating a fabric with the fabric treatment composition. The fabric treatment composition is a fabric treatment composition containing a hydroxyalkyl cellulose (A) in which a hydroxyalkyl cellulose is bound to at least one selected from a cationic group and a hydrophobic group including a hydrocarbon group having 4 or more carbon atoms, the content of a surfactant (B) being 3.5 parts by mass or less relative to 1 part by mass of the hydroxyalkyl cellulose (A).
