Specific details on test material used for the study:
- Name of test material (as cited in study report): N-nonanal; nonyl aldehyde; pelargonaldehyde
- Substance type: Colourless fruity liquid
- Physical state: Liquid
- Isomers composition: No data
- Purity test date: 2009-11-03
- Batch No: 20091103145756
- Lot No: 50000021129 ex-Bay City, USA
- Expiration date of the lot/batch:
- Stability under test conditions: > 6 months (at room temperature) after receipt at AQura 2009-11-26
- Storage condition of test material: cool; at room temperature; between 0 and 49 °C; dry; handle under Nitrogen
Surface tension:
48.1 N/m
Temp.:
20 °C
Remarks on result:
other: The test item was considered to be surface active
Conclusions:
The surface tension of aqueous solutions of the test item was determined according to OECD Guideline No. 115 and EU test method A.5 with the ring method. Surface tension at 20 °C was 46.1 mN/m. The test item was therefore considered to be surface-active.

Description of key information
