Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Conclusion on classification

Brief description of the data relevant for classification

 Degradation

Readily biodegradable: 78% in 28 days (OECD 310)

Aquatic acute toxicity

For fish: 96h, LL50 (Danio rerio): No effects up to the limit of water solubility

For aquatic invertebrates: 48h, EL50 (Daphnia magna): No effects up to the limit of water; read across solubility

For algae/aquatic plants: 72h, EL50 (Pseudokirchneriella subcapitata): No effects up to the limit of water solubility 

Aquatic chronic toxicity

For fish: no data available

For aquatic invertebrates: 21d, NOELr (Daphnia magna): No effects up to the limit of water solubility

For algae/aquatic plants: 72h, NOELr (Pseudokirchneriella subcapitata): No effects up to the limit of water solubility

 

Conclusion on classification

Based on the data above, Hydrocarbons, C11-C13 (odd numbered), n-alkanes, < 2% aromatics is considered to be readily biodegradable. The substance is poorly soluble in water, and no effects occurred up to its water solubility limit in acute tests with fish, algae and daphnia. Valid chronic toxicity data are available for algae. No chronic effects were observed up to the limit of water solubility. Therefore, Hydrocarbons, C11-C13 (odd numbered), n-alkanes, < 2% aromatics does not need to be classified and labelled as environmental hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).
