As a result, it was found that the surface of the inorganic particles can be effectively achieved by a lipophilic treatment, which is appropriately crushed and split, and a patent application was previously filed (Japanese Patent Application No. 2-200982).
issue). However, in the method of this prior invention, if the particle size of the inorganic particles as the base material is small, the milling process becomes difficult, and a large amount of energy is required to obtain the desired milled particles. It turns out that this is not always the right method. The present inventors have conducted further research on a method for overcoming such disadvantages, and as a result, when the surface of the inorganic particles is partially coated with a lipophilic substance, the above problems are effective even if the particle size is extremely small. It was found that the same effects as those of the amphiphilic particles obtained by the grinding treatment of the invention of the prior application can be obtained.

ことができる。The method for coating the surface of these inorganic particles with a lipophilic substance is not particularly limited, and any conventionally known method can be adopted. For example, the lipophilic substance is dissolved in a suitable solvent to form inorganic particles. A method of mixing and removing the solvent is preferably used. Since the lipophilic substrate formed on the surface of the hydrophilic inorganic particles is required not to be easily peeled off from the surface of the inorganic particles, it is necessary to select an appropriate combination of the inorganic particles and the lipophilic substance. Further, the surface of the hydrophilic inorganic particles, since it is necessary to make part of them lipophilic, the mixing ratio of the inorganic particles and the lipophilic substance is different depending on the particle diameter of the inorganic particles, the type of lipophilic substance, etc. By carrying out a few preliminary experiments depending on the purpose, it is possible to easily obtain amphiphilic particles having a balance of hydrophilicity and lipophilicity, which is suitable for the purpose.

とができる。By the way, in order to partially make the surface of the hydrophilic inorganic particles lipophilic, it is essential that the entire amount of the hydrophilic inorganic particles be brought into uniform contact with the lipophilic substance. In the case of the present invention, a method of thoroughly stirring the solution dissolved in the solvent and the hydrophilic inorganic particles with a disperser is particularly preferable. The selection of the volatile organic solvent is appropriately determined in relation to the solubility of the lipophilic substance, and the amount used is determined within the range suitable for the amount of hydrophilic inorganic particles and stirring and mixing. The solvent is removed from the homogeneous mixture, recovered and can be reused.

Put cc and 5 cc of water in a test tube and add about 0.
Add 5 g and shake well, and let stand for about 10 minutes to form an aggregate layer of fine oil (benzene) droplets surrounded by amphipathic particles between the lower water layer and the upper benzene layer. . If all the particles are amphipathic, in this shaking method, these particles gather only in the intermediate layer, and the benzene layer and the water layer form a substantially clear layer containing no such particles. . When this intermediate layer is observed, usually, the amphipathic particles surround the outer peripheral surface of the fragmented benzene droplets to form a stable dispersion in the continuous aqueous layer. Particles without a lipophilic coating are suspended in the lower aqueous layer, and conversely, particles fully coated with a lipophilic substance are suspended in the upper benzene layer. In the present invention, the processing conditions under which such particles are formed are inappropriate.
