Abstract: A water-soluble metalworking oil may include 0.7% by mass or more of 2-phenoxyethanol (A), based on the total water-soluble metalworking oil mass. A content of petroleum sulfonate may be less than 10 parts by mass, based on 100 parts by mass of the 2-phenoxyethanol (A). The 2-phenoxyethanol (A) may be present in a range of from 0.7 to less than 5.0% by mass. The water-soluble metalworking oil may further include: an amine, a fatty acid (C), and/or a nonionic surfactant (D).

Abstract: A water-soluble metalworking fluid composition and a method of using the same. The water-soluble metalworking fluid composition has the components (A), (B), and (C), where (A) is a fatty acid having a carbon atom number of 9-11, (B) is an unsaturated fatty acid having a carbon atom number of 16-22, and (C) is a polymeric fatty acid having an acid value of 10-200 mgKOH/g. (A) is 1-20 mass %, (B) is 30-60 mass %, and (C) is 35-55 mass %, based on the total amount of the components (A), (B) and (C). The water-soluble metalworking fluid composition maintains the workability while improving the mechanical fouling.
