- Specific details on test material used for the study:
- Identification: Reaction product of 2,3-epoxypropyl neodecanoate and Benzenesulfonic acid, C10-13-sec-alkyl derivatives
Appearance/Physical state: Brown liquid
Batch: P718261998
Purity: 97.7%
Expiry date: 01 June 2018
Storage conditions: Room temperature in the dark - Key result
- Surface tension:
- 35.4 mN/m
- Temp.:
- 20.4 °C
- Conc.:
- 90 other: % saturated solution
- Conclusions:
- The aqueous surface tension was measured to be 35.4 mN/m (mean of duplicate analyses, 90% saturated solutions) at 20.4 ± 0.5 °C, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The test item was considered to be surface-active.
- Executive summary:
The aqueous surface tension was measured to be 35.4 mN/m (mean of duplicate analyses, 90% saturated solutions) at 20.4 ± 0.5 °C, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The test item was considered to be surface-active.
Reference
On removal from the 20 °C water bath, the samples were opaque, cloudy solutions. After filtration, the samples were clear, colorless solutions free from undissolved test item with no Tyndall beam effect observed.
Description of key information
The aqueous surface tension was measured to be 35.4 mN/m (mean of duplicate analyses, 90% saturated solutions) at 20.4 ± 0.5 °C, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The test item was considered to be surface-active.
Key value for chemical safety assessment
- Surface tension:
- 35.4
- in mN/m at 20°C and concentration in mg/L:
- 1 007.1
Additional information
The concentration above is calculated as the mean of two 90% saturated solutions of the test item and assumes no loss of test item after filtering.
