Fabric treatment composition

A fabric treatment composition, comprising:

• 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,
• wherein a content of a surfactant (B) in the composition is 3.5 parts by mass or less relative to 1 part by mass of the hydroxyalkyl cellulose (A), and
• wherein the hydrophobic group including a hydrocarbon group having 4 or more carbon atoms includes at least one selected from a hydrophobic group represented by the following formula (1-1-1), a hydrophobic group represented by the following formula (1-1-2), a hydrophobic group represented by the following formula (1-2-2), and a hydrophobic group represented by the following formula (1-4):
• wherein:
• R11 and R12 each independently represent an alkylene group having 2 to 4 carbon atoms;
• R1 represents a hydrocarbon group having 4 or more carbon atoms;
• * represents a binding position to a group resulting from eliminating a hydrogen atom from a hydroxy group of the hydroxyalkyl cellulose;
• n1 represents an addition molar number of —R11—O—;
• n2 represents an addition molar number of —R12—O—;
• and
• n1 and n2 are each an integer of 0 or more and 30 or less.
