Abstract
The present invention provides a microgel having a mean particle size of 0.1-1,000 μm, the microgel being produced from a gel which is formed by use of a hydrophilic compound capable of forming a gel. An external composition containing the microgel provides an excellent sensation during use; i.e., the composition provides neither sticky sensation during use nor frictional sensation. Furthermore, even when a large amount of a pharmaceutical ingredient, such as a whitening ingredient, or a salt is incorporated into the composition, the viscosity of the composition is not lowered, and the composition exhibits excellent viscosity increasing property. In addition, the composition exhibits long-term stability, without inviting separation of water.
