A novel organopolysiloxane having a hydrophilic group, which can be produced easily and is not susceptible to two-phase separation, sedimentation of unreacted materials or the like after production, while being chemically stable and excellently practical, is disclosed. A method for producing the organopolysiloxane； and uses of the organopolysiloxane are also disclosed. The organopolysiloxane is a co-modified organopolysiloxane which has a group having a siloxane dendron structure and a hydrophilic group.
