Abstract
Intended is to provide a cation-modified silica dispersion wherein viscosity change with lapse of time is suppressed, and also intended is to suppress the variation in performance of a product using the dispersion as a raw material (for example, a polishing agent). A cation-modified silica raw material dispersion which is being stored after being adjusted to less than pH 7.0.
