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.

Description of key information

C14-20 Aliphatics (≤2% aromatic) are not toxic to microorganisms: the EC50 is greater than 100 mg/L.

Key value for chemical safety assessment

Additional information

One study dealing with toxicity to microorganisms was performed with Hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, <2% aromatics (TOTAL, 1994). The EC50was reported to be greater than 100 mg/L.

Moreover, the biodegradation studies showed that C14-20 Aliphatics (≤2% aromatic) are readily biodegradable and therefore they are not toxic to microorganisms.
