ABSTRACT OF THE DISCLOSURE Soluble-oil cutting fluid A composition for the preparation of a soluble-oil for use in a cutting fluid comprises a mineral oil and, as an emulsifier, an effective amount of a sulphonate of a branched polymer of a C3 to C5 olefin. Preferably the polyolefin chain of the sulphonate has an average molecular weight in the range 275 to 560 and the polyolefin is polyisobutene. A soluble-oil can be prepared from the above composition by the addition of a conventional corrosion inhibitor and diluted with water to make a cutting fluid. Advantages of the novel emulsifier are that they are resistant to breakdown by micro-organisms and do not require the addition of a coupling agent.
