Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.
EC number: 930-592-4 | CAS number: -

Additional information
The results of three performed in vitro tests for genetic toxicity were negative.
Short description of key information:
Three tests in vitro for the determination of genetic toxicity were performed:
The tests were performed according to the following methods:
1/ EU Method B.13/14 (Mutagenicity - Reverse Mutation Test Using Bacteria)
2/ EU Method B.10 (Mutagenicity - In Vitro Mammalian Chromosome Aberration Test)
3/ EU Method B.17 (Mutagenicity - In vitro Mammalian Cell Gene Mutation Test)
The obtaining of information concerning of mutagenicity in the tests in vitro are in accordance with reccomendations stated in Annexes VII - X of the Regulation (EC) No 1907/2006.
All testst were carried out in accordance with internationally valid GLP principles.
Endpoint Conclusion: No adverse effect observed (negative)
Justification for classification or non-classification
Because the results of all performed genotoxicity tests are negative, the test item could not be clasiffied as mutagenic.
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).
