WIPO Patent Application WO/2001/005916
Kind Code:
A1
Abstract:
A sulfurized extreme-pressure additive which contains no surfactants, is perfectly soluble in water, is reduced in odor, and has a satisfactory hue; and a cutting fluid and a grinding fluid which are excellent in antifoaming and anticorrosive properties and have high load-bearing performance and lubricating performance comparable to those of conventional cutting and grinding oils. The extreme-pressure additive comprises a salt of a condensate of a sulfurized unsaturated hydroxyfatty acid, the condensate having a sulfur content of 8 to 15 wt.%, a hue of 6 or less, and an acid value of 80 to 200.
