  • Patent number: 5417869
    Abstract: The invention relates to bioresistant surfactants and cutting fluid compositions which utilize them. The surfactants consist of soaps of carboxylic acid compounds having from 10 to 30 carbon atoms, the carbon skeleton of which is branched and not straight chain. It is the branching which lends the resistance to biodegradation to the products of the invention. Further enhanced bioresistance may be obtained by utilizing a branched lubricating basestock material in the cutting fluid composition.
