The incorporation of highly refined, low viscosity index base oils along with a polymeric thickener produces a final readily biodegradable fluid with a significantly high viscosity. The present invention allows the formulation of a high viscosity readily biodegradable fluid where the vast majority of the fluid is mineral oil. Previous uses of mineral oils only allowed for formulation of substantially lower viscosity readily biodegradable fluids.

A method is provided involving altering the viscosity of bio-derived paraffins to produce a paraffinic fluid, where the altering step includes chlorinating the bio-derived paraffins; the bio-derived paraffins include a hydrodeoxygenated product produced by hydrodeoxygenating a bio-based feed where the bio-based feed includes bio-derived fatty acids, fatty acid esters, or a combination thereof; the bio-derived paraffins include n-paraffins; and the n-paraffins have a biodegradability of at least 40% after about 23 days of exposure to microorganisms. Also provided are methods of protecting and/or cleaning a substance by applying the paraffinic fluid.
