A water-swellable clay mineral water dispersion, wherein the water-swellable clay mineral is swollen and dispersed in the nonionic surfactant-containing aqueous solution or dispersion of No. 12 above. [Effect] Since the water-swellable clay mineral is uniformly dispersed and swelled in the aqueous solution, for example, when a shearing force is applied, the viscosity of the solution increases 2 to 50 times, and sometimes 100 times or more in a few seconds to a few minutes. However, it exhibits specific behavior such as dilatancy or inverse thixotropy. Further, even if the shearing force is not applied, if the temperature of the liquid is raised or lowered, the viscosity of the liquid increases as in the case where the shearing force is applied.

中水型乳化組成物が開始されている。2. Description of the Related Art It has long been known that certain clay minerals, especially water-swellable clay minerals, form complexes with various organic compounds. According to "Development and Application of Intercalation Compound" (CMC), this complex is roughly classified into an ionic complex and a molecular complex. As an ionic complex, research on a complex using a cationic compound such as a cationic dye, an n-alkylamine salt and a cationic surfactant dodecylpyridinium chloride is known, and it is known as an organic modified bentonite. An ionic complex of an amine and bentonite is widely used as a fluidity modifier for inks, paints, greases, etc. by utilizing the property of swelling in an organic solvent. As the molecular complex, alcohol, ketone, ether,
A complex with a polar molecule such as nitrile is known. Furthermore, regarding a complex with a nonionic surfactant which is a kind of molecular complex, Hans (Kolloid Z., 199, 158 (196

55, 907 (1977)), a complex compound of water as a dispersion medium was isolated, and the formation of the complex was discussed based on the spread between clay layers observed by X-ray diffraction. The use of dispersions consisting of nonionic surfactants and water has not heretofore been omitted. Further, Japanese Patent Laid-Open No. 63-151351 has started a water-in-oil emulsion composition containing an oil component as an essential component in addition to a water-swelling clay mineral, a nonionic surfactant and water.
