Composition

A composition comprising:

• a modified hydroxyalkyl cellulose;
• and
• at least one selected from an anionic surfactant and a nonionic surfactant,
• wherein the modified hydroxyalkyl cellulose is one in which a cationic group and a hydrophobic group are bound to a group resulting from eliminating a hydrogen atom from a hydroxy group of a hydroxyalkyl cellulose, and
• wherein the hydrophobic group comprises at least one selected from a hydrophobic group represented by the following formula (1-1-1) and a hydrophobic group represented by the following formula (1-1-2):
• wherein:
• R11 represents an alkylene group having 2 to 4 carbon atoms;
• R1 represents a hydrocarbon group having 2-14 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—;
• and
• n1 is an integer of 0 or more and 30 or less.
