EC number: 309-886-6 | CAS number: 101316-84-1 A tar obtained from low temperature carbonization and low temperature gasification of brown coal. Composed primarily of aliphatic, naphthenic and cyclic aromatic hydrocarbons, heteroaromatic hydrocarbons and cyclic phenols.
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
The inhalation study was not performed, the exposure is supposed to be insignificant.
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
From the results of both acute toxicity studies (oral and dermal) follows that the substance could not be classified as hazard substance.
LD50 > 2000 mg/kg bw (oral)
LD50 > 2000 mg/kg bw (dermal)
Justification for classification or non-classification
According to the results of the studies, the value of LD50 (oral and dermal) of the test substance - Tar, brown-coal, low-temp. - for rats of both sexes is higher than 2000 mg/kg of body weight (Rosslerova Z., 2010a, b).
The test substance - Tar, brown-coal, low-temp.is classified as Asp. Tox. 1; H304 May be fatal if swallowed and enters airways - according to Regulation (EC) No 1272/2008 criteria based on its physical and chemical properties (hydrocarbon, kinematic viscosity ≤ 20.5mm²/s at 40°C) and is not classified as Xn; R65 Harmful: may cause lung damage if swallowed according to Directive No. 67/548/EEC (kinematic viscosity > 7x10-6m2/s at 40°C).
