Abstract

The present invention relates to a process for heavy alkylate based less toxic metalworking fluid composition comprising heavy alkyl benzene, one emulsifier which is a sodium oleate, sulfonate or mixtures thereof, a vegetable oil as lubricity booster, an antioxidant, a fungicide, an extreme pressure additive, an antirust, a co-surfactant, a coupling agent and alkali component. The process comprises removing of insoluble matter from the heave alkylate, addition of emulsifier, additives, coupling agent and co-surfactant, homogenizing the mixture at 20 - 120~C, followed by conditioning of the metal working fluid concentrate which can be used as emulsion in water.
