Abstract: A starting (raw) material, for cosmetics, comprising a core corona type microgel dispersion obtained by radical polymerization of a specific polyethylene oxide macromonomer, a specific hydrophobic monomer, and a specific cross-linking monomer under specific conditions. The purpose of the present invention is to provide the raw material for cosmetics, with which the cosmetic having a high stability provides a good feeling in use and does not cause skin irritation, can be easily produced.
