(54) SILICONE MODIFIED WITH BRANCHED POLYGLYCEROL


(57) The invention provides a novel hydrophilic silicone compound for use in extremely wide areas that is, for example, less irritating, less yellowing, superior in wettability and adsorptivity to various media while having high hydrophilicity and the advantages inherent in silicones all together. The invention provides a branched polyglycerol-modified silicone, silicon atoms of which are connected to at least one branched polyglycerol chain having one or more branched glycerol groups represented by the following formula (1) via a connecting group, a method for producing the same, and a cosmetic containing the same: wherein, two oxygen atoms each independently bind to a glycerol or glycidol group represented by formula (1) above or the following formula (2), (3), or (4)
