the material is expected to be stable in the environmental pH region where 4<pH<9. In addition the low water solubility would not favour hydrolysis reactions due to the limited contact between susceptible groups and the aqueous environment. Measurement of the n-octanol/water partition coefficient was attempted using an HPLC method. However, only 4.3% of the compound could be dissolved in acetonitrile and this had a log Pow of 5.2. Since the material has a substantial alkyl moiety, the notifier suggested a log Pow value of greater than 8. No adsorption/desorption data were provided, but the high log Pow and high hydrocarbon content indicates that the material have a large Koc and adsorb strongly to the organic component of soils and sediments. No dissociation constant data were provided. The tertiary portion of the molecule is expected to exhibit basic properties with a pKa between 9.5 and 10.5. 4. PURITY OF THE CHEMICAL Degree of Purity: 19.5% Hazardous Impurities: There are 3 hazardous impurities, 2 of which are identified as skin irritants, to a total of 1.6%. Non-hazardous Impurities Total of 23.9% of non-hazardous impurities. (> 1% by weight): Additives/Adjuvants: Lubricating oil, to a final concentration of 55%, is added during manufacture to reduce the viscosity of the notified chemical so that it can be pumped from the reactor. The oil consists of Distillates, hydrotreated heavy paraffinic (CAS No. 64742-54-7) or Distillates, solvent refined heavy paraffinic (CAS No. 64741-88-4). 5. USE, VOLUME AND FORMULATION The notified chemical is a lubricant additive for railroad diesel engines. It is to be imported in a lubricant additive package OLOA 2000. OLOA 224 will be contained in the additive package at 15% and will be blended in railroad oils at 2.3 6%. The lubricant additive – package containing the notified chemical is to be imported in 200 L drums and the amount of the notified chemical to be imported is up to 2.25 tonnes per annum for the first 5 years. 6.
