A WATER DISPERSION AND A METHOD FOR PRODUCING A WATER DISPERSION, ALSO, AN OIL-IN-WATER EMULSION, A METHOD FOR PRODUCING AN OIL-IN-WATER EMULSION AND A METHOD FOR DESIGNING AN OIL-IN-WATER EMULSION
Aqueous dispersions which exhibit properties required of an aqueous dispersion and achieve stability and homogeneity include inorganic particle groups dispersed in an aggregation state in water. In this dispersion, when the total mole number ratio represented by moles of surface hydrophilic groups of the inorganic particle groups moles of surface hydrophobic groups is within a prescribed lower limit value or more depending on the aggregating properties of inorganic particles, the inorganic particle groups contain self-micelle-like aggregates and hydrophobic-rich aggregates.
