A surfactant composition for agricultural chemicals, containing fatty acid polyoxyalkylene alkyl ether expressed by the following general formula (I),RCO(EO)(PO)OR&#x2003;&#x2003;(I)wherein the fatty acid polyoxyalkylene alkyl ether has a narrow ratio of 55% by mass or more, where the narrow ratio is expressed by the following formula (A):Narrow ratio=&#x3a3;&#x2003;&#x2003;(A).

Surfactant composition for agricultural chemicals

A water-insoluble cutting fluid base oil or grinding fluid base oil for metalworking includes a fatty acid polyoxyalkylene alkyl ether represented by the following formula (I-A), wherein a hydroxyl value of the fatty acid polyoxyalkylene alkyl ether is less than or equal to 2.0 mgKOH/g.R&#x2014;CO-(OA)-OR&#x2003;&#x2003;(I-A)(In the formula (I-A), Rrepresents a linear or branched, saturated or unsaturated monovalent hydrocarbon group having 15 to 21 carbon atoms and Rrepresents a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 8 carbon atoms. In addition, A represents an alkylene group having 2 to 4 carbon atoms, OA represents alkylene oxide, and n represents 1 to 6 which is an average mole number of added alkylene oxide (AO)).
