The invention provides a soil improvement agent composition which contains (A) a fatty acid polyoxyalkylene alkyl ether represented by formula (1): RCO (EO)m (PO)n OR(1) wherein Ris a straight-chain or branched hydrocarbon group having 13 to 21 carbon atoms, EO represents ethylene oxide, m is a number of 2 to 10, PO represents propylene oxide, n is a number of 1 to 4, and Ris a hydrocarbon group having 1 to 3 carbon atoms; and (B) a polyoxyalkylene alkyl ether represented by formula (2): RO (EO)x (PO)y H (2) wherein Ris a straight-chain or branched hydrocarbon group having 8 to 14 carbon atoms, EO represents ethylene oxide, x is a number of 7 to 12, PO represents propylene oxide, and y is a number of 0 to 3.

Soil improvement agent composition

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)).

Metalworking fluid base oil

Sulfonated styrene polymer and/or its salt, a waste water treatment material and sludge dehydrating agent each containing the sulfonated styrene polymer and/or its salt as an effective component thereof are disclosed. The waste water treatment material is used such that sulfonated styrene polymer and/or its salt, which has viscosity of 10 mPa&#xb7;S to 20,000 mPa&#xb7;S at 25&#xb0; C. after 0.01 N to 5 N neutral salt has been added to 1 wt % water solution of the sulfonated styrene polymer and/or its salt, is added to each waste water so that waste water is purified. When a sludge dehydrating agent is required, sulfonated styrene polymer and/or its salt having a weight average molecular weight of 1,100,000 or greater is combined with a cation polymer flocculating agent or an inorganic flocculating agent.
