<p>There is disclosed a novel glycerol group-containing organopolysiloxane is formed of a glycerol group-containing substituent shown by the following general formula (1) which is bonded to at least one silicon atom of a main chain organopolysiloxane segment,
wherein each X and Y independently represents a divalent hydrocarbon group having 1 to 10 carbon atoms; m represents an integer of 0 to 4; and Z represents an organic group shown by the following general formula (2),
wherein R a represents a divalent hydrocarbon group having 2 to 12 carbon atoms; and m' represents an integer of 1 to 5. As a result, there is provided a novel glycerol group-containing organopolysiloxane and a method for producing it without requiring special purification processes, and in addition, provided is a cosmetic not generating an odor with passage of time while giving a moist feeling without stickiness.</p> |
