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 auto flammability of the Hydrocarbons, C9, aromatics is >400°C at 1 atm.

The autoignition temperature of Hydrocarbons, C10, aromatics, >1% naphthalene is >400°C according to published material.

 

This data is used for read across to Hydrocarbons, C9-C10, aromatics, >1% Naphthalene.

Key value for chemical safety assessment

Additional information

The auto flammability of the Hydrocarbons, C9, aromatics was calculated to be >400°C.

 

The autoignition temperature of Hydrocarbons, C10, aromatics, >1% naphthalene is >400°C according to published material.
