The present invention does not have, as a hydrophilic group, an oxyalkylene structure in which the average value of the repeating number of oxyalkylene units having 1 to 6 carbon atoms is 2 or more, and the average value of the repeating number of the glycerin unit is in the range of 1.0 to 2.4. It relates to a glycerin derivative-modified organopolysiloxane elastomer having a derivative group and also having a crosslinked three-dimensional network structure including a carbon-silicon bond in the crosslinking portion. The organopolysiloxane elastomer of the present invention is excellent in affinity with various oils, emulsifying properties, thickening properties, gelling properties, structural control properties, and excellent touch (particularly velvety smoothness). At the same time, it can give a good feeling of dryness and less stickiness. In addition, according to the present invention, an external preparation having no emulsification stability and containing no compound containing a polyoxyethylene structure in accordance with the global trend of improving the composition of end consumer products such as cosmetics as a whole by PEG-FREE prescription Cosmetics can be provided. |
