Claim:
1. A nonionic surfactant composition comprising: a nonionic surfactant that comprises a molecule having a C 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 wherein the nonionic surfactant comprises a nonionic surfactant represented by the formula (1): wherein R 1 is a C 13 linear or branched alkyl group (except a C 13 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 a C 13 alkyl group derived from an alcohol that is produced from a higher olefin derived from a propylene tetramer through an oxo process), and n 1 is an integer of 5 to 15, and a nonionic surfactant represented by the formula (2): wherein R 2 is a C 10 -C 16 linear or branched alkyl group (except a C 10 -C 14 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 a C 13 alkyl group derived from an alcohol that is produced from a higher olefin derived from a propylene tetramer through an oxo process), n 2 is an integer of 5 to 20, and m is an integer of 1 to 6, and wherein a molar ratio (1)/(2) of the nonionic surfactant represented by the formula (1) to the nonionic surfactant represented by the formula (2) is (99 to 60)/(1 to 40).
