Disclosed are: 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 the production, while being chemically stable and excellently practical; a method for producing the organopolysiloxane; and use of the organopolysiloxane. Specifically disclosed are: a novel co-modified organopolysiloxane which has a group having a siloxane dendron structure and a hydrophilic group; a method for producing the co-modified organopolysiloxane; a surfactant and a powder processing agent which are respectively composed of the co-modified organopolysiloxane; and a cosmetic preparation which contains the co-modified organopolysiloxane. L'invention concerne un nouvel organopolysiloxane ayant un groupe hydrophile, qui peut être obtenu facilement et qui n'est pas sensible à la séparation en deux phases, à la sédimentation de matières n'ayant pas réagi ou similaires après la fabrication, tout en étant chimiquement stable et extrêmement pratique ; un procédé de fabrication de l'organopolysiloxane ; et l'utilisation de l'organopolysiloxane. De façon spécifique, l'invention porte sur un nouvel organopolysiloxane co-modifié qui a un groupe ayant une structure de dendron de siloxane et un groupe hydrophile ; sur un procédé de fabrication de l'organopolysiloxane co-modifié ; sur un agent tensio-actif et un agent de traitement des poudres qui sont composés respectivement de l'organopolysiloxane co-modifié ; et sur une préparation cosmétique qui contient l'organopolysiloxane co-modifié.
