Description of key information

Additional information

There is no data available for Hydrocarbons, C12-C16, n-alkanes, isoalkanes, cyclics, 2-25% aromatics. Data is read across from structural analogues such as Hydrocarbons, C9-C14 aliphatics, 2-25% aromatics and Hydrocarbons, C14-C20 aliphatic, 2-30% aromatics. Hydrocarbons, C12-C16, n-alkanes, isoalkanes, cyclics, aromatics (2-25%) straddles Hydrocarbons, C9-C14, Aliphatics, (2-25% Aromatics) and Hydrocarbons, C14-C20, Aliphatics (2-30% Aromatics). Read across justification documents have been provided for the same in Section 13 of the dossier. For this substance, a worst case scenario approach has been used for each endpoint.

Hydrocarbons, C10-C13, n-alkanes, isoalkanes, cyclics, aromatics (2-25%), biodegraded 75% after 28 days under the conditions of the study and is readily biodegradable.

C14-C20 Aliphatics (2-30% Aromatics), multi-component substances, biodegraded to an extent of 61% after 28 days in an OECD 301F study. The data support characterizing the test substance(Hydrocarbons, C14 -C18, n-alkanes, isoalkanes, cyclics, aromatics(2 -30%)) as rapidly biodegradable, readily biodegradable, not expected to persist in the environment under aerobic conditions. Although it did not meet the 10 -day window requirement, it is characterized as readily biodegradable because the criteria is not applied to multi-component substances when assessing their ready biodegradability.

These data are used as read across data forHydrocarbons, C12-C16, n-alkanes, isoalkanes, cyclics, 2-25% aromatics.

Degradation rates

Half-lives were estimated using the PETRORISK model (see Product Library in PETRORISK spreadsheet attached to IUCLID section 13).
