Abstract (en)
[origin: WO8805808A1] Hydraulic fluids based on natural triglycerides. The base composition for these hydraulic fluids consists of at least one natural triglyceride and one anti-oxidant additive. The triglyceride suitable for the composition can be defined as an ester of a straight-chain C10 to C22 fatty acid and glycerol which has an iodine number of between 50 and 128. The fraction of the anti-oxidant additives is selected preferably among hindered phenolics and aromatic amines, but can be completed by compounds selected from metal salts of dithioacids, phosphites, sulfides, amides, non-aromatic amines, hydrazides and triazols. Preferred amount of the anti-oxidant(s) in the fluid is 1.5 to 4.5 percent by weight.
