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).
