Abstract
The present invention provides a (poly)alkylene glycol-containing compound having higher detergency for composite stains of hydrophilic stains and hydrophobic stains than conventional (poly)alkylene glycol-containing compounds. The present invention relates to a (poly)alkylene glycol-containing compound including: a hydrophobic structural moiety (A); a (poly)alkylene glycol moiety (B); and one lactam ring-containing structural unit (C), in its structure, the hydrophobic structural moiety (A) being present in a proportion of 2.5 to 60% by mass in 100% by mass of the (poly)alkylene glycol-containing compound.
