0.02 mg/L). The normal OECD methods of determining this parameter were not used because the estimated log Pow value falls outside the limits applicable to these methods (ie. OECD Methods 107 & 117 are applicable over log Pow values –2 to 4 and 0 to 6, respectively). The partition coefficient indicates a high affinity to lipids. The adsorption coefficient, Koc, of the notified polymer was estimated from the empirical relationships with the partition coefficient, Pow, and the water solubility, S (Lyman et al. 1982). The estimated log Koc value, based on the partition coefficient, is >5.6, whereas the estimated log Koc based on the water solubility is >4.6. On the basis of these values, the log Koc of ESTER 6 was estimated to be >5. These results indicate the notified chemical is immobile in soils. The dissociation constant was not measured due to low water solubility (ie. <1mg/L) of the notified chemical. There are no groups able to dissociate. The hydrolysis as a function of pH values was not measured due to low water solubility (ie. <1mg/L) of the notified chemical. The esters present have the potential to hydrolyse but not in the environmental pH range of 4 to 9 due to the low solubility. The flammability test was not performed as it was found that the notified chemical did not evolve gas on exposure to water in other studies. Pyrophoric properties were not determined as the notified chemical did not ignite on prolonged exposure to air. 4. PURITY OF THE CHEMICAL The degree of purity has been exempted from publication in the Full Public Report and the Summary Report. Hazardous Impurities: None Non-hazardous Impurities (> 1% by weight): None Additives/Adjuvants: None 5. USE, VOLUME AND FORMULATION The notified chemical will be imported into Australia exclusively as a component of finished hydraulic oil formulations in 200 L drums. The concentration of the notified chemical in the finished hydraulic oils will be 95 %. Import volumes for the notified chemical will be less than 10 tonnes per annum increasing to 100 tonnes in 5 years. The finished hydraulic oils will be added directly to hydraulic systems in large mobile equipment. The hydraulic oils will be transferred from the 200 L steel drums directly to hydraulic systems using a standard drum pump.
