Abstract

Provided is a release agent for vulcanized rubber molding, the release agent exhibiting good mold releasability between a mold and a rubber after vulcanization and capable of being easily removed after production. The release agent for vulcanized rubber molding contains a polyoxyalkylene glyceryl ether (A). The polyoxyalkylene glyceryl ether (A) contains 50% to 95% by mass of oxyethylene groups in 100% by mass of oxyalkylene groups. The polyoxyalkylene glyceryl ether (A) preferably has a number-average molecular weight of 2,000 to 20,000.
