- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Standard method used however not conducted under GLP.
- Justification for type of information:
- 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.
- Reason / purpose for cross-reference:
- read-across: supporting information
- Qualifier:
- according to guideline
- Guideline:
- other: Wilhelmy Plate
- Deviations:
- no
- Principles of method if other than guideline:
- Wilhelmy plate method is used to measure the surface tension using a standardized plate with a ring/plate tensiometer. The plate is moved towards the surface until the meniscus connects with it. The surface tension is calculated from the resulting force. Due to uncertain wetting behavior, the plate can only be used for interfaces under certain limitations.
- GLP compliance:
- no

Description of key 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. 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.
The surface tension at 25°C of Hydrocarbons, C9 -C12, n-alkanes, isoalkanes, cyclics, aromatics (2 -25%) is between 24 and 27 mN/m using Wilhelmy plate method.
The surface tension at 25°C of Hydrocarbons, C10-C13, n-alkanes, isoalkanes, cyclics, aromatics (2-25%) is between 25 and 27 mN/m using Wilhelmy plate method.
The surface tension at 25°C of Hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, aromatics (2-30%) is 28 to 30 mN/m according to the Wilhelmy plate method.
These data are used as read across data for Hydrocarbons, C12-C16, n-alkanes, isoalkanes, cyclics, 2-25% aromatics.
