Description of key information
Hydrocarbons, C9-C10, aromatics, >1% Naphthalene are a combination of Hydrocarbons, C9 Aromatics and Hydrocarbons, C10-C12 Aromatics. Read across data is available for Hydrocarbons, C9 Aromatics and Hydrocarbons, C10-C12 Aromatics and the worst case scenario for each end point has been presented.
The viscosity of the Hydrocarbons, C9 aromatics ranges from 0.7-1.7 mm²/s at 20°C.
The viscosity of Hydrocarbons, C10, aromatics, >1% naphthalene is 0.8 to 2.0 mm2/s at 20°C.
This data is used for read across to Hydrocarbons, C9-C10, aromatics, >1% Naphthalene.
Key value for chemical safety assessment
Additional information
The viscosity of the Hydrocarbons, C9, aromatics ranges from 0.7-1.7 mm2/s according to method ASTM D7042.
The viscosity of Hydrocarbons, C10, aromatics, >1% naphthalene is 0.8 to 2.0 mm2/s at 20°C according to the ASTM D 7042 testing methodology.
