AQUEOUS DISPERSION, METHOD FOR PRODUCING AQUEOUS DISPERSION, OIL-IN-WATER EMULSION, METHOD FOR PRODUCING OIL-IN-WATER EMULSION, AND DESIGN METHOD

Provided are an aqueous dispersion which exhibits properties required of an aqueous dispersion and achieves the stability and homogeneity of an aqueous dispersion, and a method for producing the aqueous dispersion. The aqueous dispersion of inorganic particles includes inorganic particle groups dispersed in an aggregation state in water. In this dispersion, when the total mole number ratio represented by (the total number of moles of surface hydrophilic groups of the entire inorganic particle groups obtained from each of the inorganic particle groups/the total number of moles of surface hydrophobic groups of the entire inorganic particle groups obtained from each of the inorganic particle groups) is within a value range of 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.
