PROBLEM TO BE SOLVED: To provide a thermoplastic synthetic fiber requiring absorption property and a hydrophilizing agent for fiber, which provides especially a polyolefin-based nonwoven fabric with excellent initial hydrophilicity and durable hydrophilicity. SOLUTION: The hydrophilizing agent for fiber includes a compound obtained by adding an alkylene oxide to one or two or more kinds of alkenyl phenols represented by general formula (1) (wherein R is 13-17C alkenyl; AO is 2-4C alkylene oxy; n is integer of 1-20; in the case of adding two or more kinds of alkylene oxy groups, either block addition or random addition may be carried out).
