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: -
Endpoint summary
Administrative data
Description of key information
The tests of Acute oral toxicity and Acute dermal toxicity were performed according to the following methods:
Method B.1 tris: Acute Oral Toxicity - Acute Toxic Class Method, Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008.
Method B.3 Acute Toxicity (Dermal), Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008.
Both: GLP study
Key value for chemical safety assessment
Acute toxicity: via oral route
Endpoint conclusion
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
Acute toxicity: via dermal route
Endpoint conclusion
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
Additional information
Justification for classification or non-classification
From the results of both acute toxicity studies (oral and dermal) follows that the substance is not classified as hazard substance.
LD50 > 2000 mg/kg bw (oral)
LD50 > 2000 mg/kg bw (dermal)
