Fecha de publicación: -- Fuente: WIPO "tomato" A lubricity additive composition for an industrial lubricant composition is described herein. The industrial lubricant composition may be a metalworking fluid to reduce the heat and friction between a cutting tool and a metal substrate. The lubricity additive composition for an industrial lubricant composition may comprise a polyglycerol ester, wherein the polyglycerol ester has a hydrophobic-lipophilic balance ("HLB") value of about 3 to about 15, and a polyethylene glycol ester, wherein the polyethylene glycol ester has a hydrophobic-lipophilic balance ("HLB") value of about 10 to about 20. The disclosure is also generally directed to methods for increasing the lubricity of an industrial lubricant composition on a metal substrate
