Abstract
A method for producing a silica microcapsule having a shell containing silica as a constituent component and a core containing one or more organic compounds inside the shell. The method includes subjecting an emulsified liquid obtained by emulsifying an aqueous phase component containing a cationic surfactant and an oil phase component containing one or more organic compounds and a silica source to a sol-gel reaction in the presence of one or more sulfur-containing ions selected from the group consisting of a sulfate ion, a sulfite ion, and a sulfonate ion to form the silica microcapsule.
