- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch number of test material:
20200206
- Expiration date of the lot/batch:
31/12/2020 - Key result
- Surface tension:
- ca. 31.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Conclusions:
- The Surface tension of the test item, Isodecyloxypropylamin (IDOPA), is 35.28 dyn/cm (measured) and 31.5 mN/m (calculated)
- Executive summary:
The Surface tension was measured. The test item, 90% saturated solution, was used.
The measurement was performed according to the by OECD harmonized ring method (OECD Principles of Good Laboratory Practice (as revised in 1997) C (97) 186 (Final). - Directive 204/10/EC of the EP and of the Council, February 2004)
The surface tension for Isodecyloxypropylamin (IDOPA), 90% saturated solution, is 35.28 dyn/cm (measured) and 31.5 mN/m (calculated)

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
