An emulsion coagulant for coagulating a tire puncture sealant containing emulsion particles includes a mineral which induces aggregation of the emulsion particles by one or both of weakening of surface charge of the emulsion particles and formation of hydrogen bond between the mineral and the emulsion particles, and a gelation agent. The emulsion coagulant enables easy recovery of the tire puncture sealant from a tire as well as easy disposal of the recovered sealant.
