Method of producing hinokitiol-containing material for improving living environment

Abstract

In preparing a hinokitiol-containing residential environment improving material including a porous particulate matter having pores into which an oil extracted from a tree containing hinokitiol is adsorbed, there are carried out a mixed liquid preparation step including mixing the extracted oil with an alcohol, an adsorption step including mixing the porous particulate matter with the resulting mixed liquid to allow the mixed liquid to be adsorbed into the pores of the porous particulate matter, and an alcohol removal step including removing an alcohol component from the mixed liquid adsorbed into the pores of the porous particulate matter. By carrying out these steps, the adsorption of the extracted oil into the porous particulate matter and the operability thereof can be improved.
