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.
