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.

Category for CAS 92045-41-5

Justifications and discussions

Category definition:
Lubricating oils, used and not
Category description:
Within the category, the substances were considered in the following order: (1) EC 274-635-9 (Lubricating oils, used), (2) EC 295-422-7 (Lubricating oils, used, vacuum distd.), (3) EC 265-161-3 (Lubricating oils (petroleum), hydrotreated spent).
Category rationale:
In order to assess the toxicity profile of the substance of interest (EC 295-422-7, CAS 92045-41-5 used as intermediate according to REACH regulation), a category approach was used. The category was build up considering the technological cycle before and after the intermediate.
The substance "lubricating oil, used" (EC 274-635-9, CAS 70514-12-4) was considered at one side of the category: the intermediate may be obtained starting from this substance.
On the other side, the substance "Lubricating oils (petroleum), hydrotreated spent" (EC 265-161-3, CAS 64742-58-1) was used: it is one of the possible substances obtained from the intermediate.
The process pathway going from the used oil to the re-refined oil includes some steps suitable to eliminate contaminants and impurities.

When similar results were observed for the two members at the extreme sides of the category, the information was applied to the substance of the interest too. When toxicologically relevant results suggesting some kind of harm were observed for the final substance, they were applied to the substance of interest too.
In the other cases (e.g. harmful raw material and not harmful re-refined oil, data available only for the raw material) read across was omitted or the results were considered inconclusive.
