In contingency planning for alternative hydraulic fluids in the event that critical shortages should occur in the supply of petroleum based fluids, the US Navy has investigated various synthetic compounds including polyalphaolefins. Earlier toxicity assessments (1983) on five formulations of polyalphaolefin hydraulic fluids and a base fluid indicated that one formation (N501) was toxic via inhalation. This material was reformulated (now designated B85-174) and retested along with its base polyalphaolefin (R-1061-3). The LC50 values for the reformulated hydraulic fluid B85-174 were 1.60 and 1.37 mg/L for male and female rats, respectively. Nor was the material irritating to the skin or eyes of treated rabbits. Similar results were obtained from tests on the base polyalphaolefin used for comparison. In contrast, the previous base material demonstrates con inhalation toxicity. THe 1983 and 1986 polyalphaolefin base materials were obtained form different suppliers and infrared analysis demonstrated compositional differences.
