    • The present invention aims to provide a nonionic surfactant composition capable of providing an aqueous dispersion that has excellent mechanical stability and storage stability, is less viscous at high temperatures and high concentrations, and is less likely to give off an odor during drying and firing. The present invention relates to a nonionic surfactant composition including: a nonionic surfactant that comprises a molecule having a C10-C22 alkyl group and/or alkenyl group as a hydrophobic group, a polyoxyalkylene chain as a hydrophilic group, no aromatic ring, no C9-C14 alkyl group derived from an alcohol that is produced from a higher olefin derived from a mixture of propylene and butene through an oxo process, and no C13 alkyl group derived from an alcohol that is produced from a higher olefin derived from a propylene tetramer through an oxo process, wherein the nonionic surfactant has a hydrodynamic radius of 5.0 to 8.0 nm at 40°C in an aqueous solution in which a nonionic surfactant concentration is 0.1 kg/L in the nonionic surfactant composition, the radius being measured by a dynamic light scattering method.
