PURPOSE:To make it possible to add a volatile substance at low temp., to minimize the loss due to volatilization and to obtain the title compsn. whose gel condition is stable at high temp., by using a specific high-MW polysaccharide as a gelling agent in preparing a transparent gel-like compsn. of the volatile substance. CONSTITUTION:0.1-3.0wt.% high-MW polysaccharide represented by the formula based on the total amt. of a compsn. is added to water and the mixt. is heated (e.g., at 90 deg.C), stirred, dissolved and then cooled (e.g., at about 50 deg.C). A volatile substance selected from perfumes, deodorants, mothproofing agents, insecticides and repellents, a proper amt. of a surface active agent (e.g., nonionic substance) for solubilization and if necessary, an anti-freezing agent (e.g., polyhydric alcohol) and an antiseptic agent are added thereto and the mixt. is furthermore stirred, left for cooling (e.g., to about 40 deg.C), filled in a container and furthermore left for cooling to room temp. to obtain the title compsn. |
