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 upper and lower flammability ranges for the Hydrocarbons, C9, aromatics are 0.7 - 7.0% v/v.

The calculated flammability range of Hydrocarbons, C10, aromatics, >1% naphthalene is 0.6 to 7.0% v/v.

 

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

Key value for chemical safety assessment

Flammability:
flammable

Additional information

The upper and lower flammability ranges for the Hydrocarbons, C9, aromatics are 0.7 - 7.0% v/v.

The calculated flammability range of Hydrocarbons, C10, aromatics, >1% naphthalene is 0.6 to 7.0% v/v.

Justification for classification or non-classification

The flash point of the Hydrocarbons, C9, aromatics is >35°C at 1 atm. The flash point, PMcc, of Hydrocarbons, C10, aromatics, >1% naphthalene, is >62°C.

Based on the flash point of Hydrocarbons, C9, aromatics (>35C), Hydrocarbons, C9-C10, aromatics, >1% Naphthalene is classified as Flammable Category 3 (H226: Flammable liquid and vapour) under Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures.
