Environmentally preferred fluids and fluid blends

This invention relates to the selection and use of environmentally preferred fluids and fluid blends which exhibit low or reduced reactivity with respect to ozone formation. These environmentally preferred fluids and fluid blends are useful in a number of applications, particularly as industrial solvents, and allow formulators an effective means to improve the environmental performance of their formulations or products. An industrial formulation-fluid system comprising one or more organic volatile formulation-fluids including a fluid F being a compound containing either an oxygen-containing or nitrogen-containing functional group and being substantially free from unsaturated carbon-carbon bonds or aromatic groups. Fluid F is selected from the group consisting of: carbonates, acetates, dioxalanes, pivalates, isobutyrates, pentanoates, propionates, hexanoates, nonanoates, nitriles and mixtures of any two or more thereof, such that fluid F exhibits a reduction in ozone formation in an amount of at least 10% less than that of the formulation-fluid system without fluid F. Also, fluid F has an ozone formation potential (OFP) (in accordance with the Absolute MIR scale in units of g. ozone/g. fluid F) of 1.5.
