Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 300-226-2 | CAS number: 93924-32-4 A complex combination of hydrocarbons obtained by treatment of Foot's oil with natural or modified clay in either a contacting or percolation process to remove the trace amounts of polar compounds and impurities present. It consists predominantly of branched chain hydrocarbons with carbon numbers predominantly in the range of C20 through C50.

Read across justification
Several criteria justify the use of the read across approach to fill data gaps for foots oils using other lubricant base oil analogs. Primarily the basis for the read-across is the similar physical chemical properties shared by the foots oils and other lubricant base oils.
Short-term toxicity to aquatic invertebrates has been filled by read-across of measured data from other lubricant base oils. It is supported in a weight of evidence approach by a calculated value using composition information derived from two dimensional gas chromatography in conjunction with the PETROTOX model.
In a read-across 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 ≥ 10,000 mg/L (Shell, 1988).
In a read-across 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).
Results of computer modelling to estimate aquatic toxicity show no acute toxicity of foots oil to freshwater aquatic invertebrates at or below its maximum attainable water solubility (Redman et al., 2010b). These results support the applied read across.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
