Abstract
The present invention has an object to provide a polyalkylene glycol-based polymer having high anti-soil redeposition ability in washing treatment and having high compatibility with surfactants. The polyalkylene glycol-based polymer includes: a structure unit (a) derived from a polyalkylene glycol-based monomer (A) of a specific structure, and a structure unit (b) derived from a carboxyl group-containing monomer (B) at specific ratios.
