EC number: 265-159-2 | CAS number: 64742-56-9 A complex combination of hydrocarbons obtained by removal of normal paraffins from a petroleum fraction by solvent crystallization. It consists predominantly of hydrocarbons having carbon numbers predominantly in the range of C15 through C30 and produces a finished oil with a viscosity of less than 100 SUS at 100°F (19cSt at 40°C).

Additional information
In a key static 48-hour short-term Daphnia magna toxicity test (OECD 202; KS = 2), 10 animals/loading were exposed to the Water Accommodated Fraction of an other lubricant base oil, MVI(N) 40 base oil (CAS # 64742-53-6 or 64741-97-5), at nominal concentrations of 0, 10, 100, 1000, and 10,000 mg/L. The EL50 was >10,000 mg/L based on mobility and the NOEL was ≥ 1000 mg/L (Shell, 1988).
In a key semi-static 96-hour short-term freshwater shrimp (Gammarus pulex) toxicity test (OECD 202; KS = 2), 10 animals/loading were exposed to the WAF of an other lubricant base oil, MVI(N) 40 base oil (CAS # 64742-53-6 or 64741-97-5), at nominal concentrations 0, 10, 100, 1000, and 10,000 mg/L. The LL50 was >10,000 mg/L and the NOEL was ≥ 10,000 mg/L (Shell, 1988).
These studies are scientifically sound and satisfy the guideline requirements for short-term invertebrate tests.
