Provided is a monomer composition for which there is little to no concern about safety when used as a raw material or the like in a cosmetic material and that does not cause deterioration in quality such as gelation or the like. A method for manufacturing the monomer composition is also provided. A monomer composition containing a radical polymerizable monomer having a radical polymerizable organic group and an organosilicon-containing organic group in a molecule, wherein a total concentration of a polymerization inhibitor based on a total mass of the radical polymerizable monomer and the polymerization inhibitor is 130 ppm by mass or less.
