Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reaction product of Crude sludge and Calcium oxide. Crude sludge is the mixture of by-products of petroleum hydrocarbons refining (especially Total petroleum hydrocarbons, Polycyclic aromatic hydrocarbons, acid-refined heavy petroleum distillates). The Crude sludge is neutralised by calcium oxide in the ratio 80:20. The maturing process proceeds under ambient conditions and takes for at least 3 days. Subsequently, the reaction product is processed mechanically.

Description of key information
Due to character of the substance (complex material containing both inorganic and organic substances) it is not possible to perform Partition coefficient study.
The calculation of log Kow for the inorganic phase is not possible - no (Q)SAR methods are applicable for inorganic substances. The value of partition coefficient is additionally not required by REACH (Annex VII, 7.8, column 2).
The calculation of log Kow of the main of the organic phase is not possible because no of the organic substance contained in the tested substance is not possible to describe as the main component.
The estimation of log Kow based on identified organic substances was performed. The literature data for identified organic substances were used.
The range of log Kow based on the values for identified organic substances is estimated 2.13-6.58.
Key value for chemical safety assessment
Additional information
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.
