2. Description of the Related Art Conventionally, bath agents in which titanium oxide is dispersed in bath water have been used for the purpose of enjoying the feeling of a hot spring, but most of them are powder or solid bath agents, and there are almost no liquid bath agents. Was. The reason is that it is difficult to stably disperse titanium oxide in a liquid preparation for a long period of time. When titanium oxide is dispersed in a liquid, there is a problem that the titanium oxide particles are aggregated and settled due to an intermolecular force and specific gravity of the particles.

Each metal oxide has its own isoelectric point, and the isoelectric point of titanium oxide is around pH 6.
When the surface of the titanium oxide particles is coated with another metal oxide, the surface characteristics of the particles show the characteristics of the metal oxide and have the same isoelectric point as the metal oxide. Therefore, by coating the surface of the titanium oxide particles with a metal oxide having an isoelectric point of pH 7 or more, such as alumina (Al 2 O 3 ) or zinc oxide, it is possible to obtain a surface-treated titanium oxide having an isoelectric point of pH 7 or more.
