- Analytical purity: 97.2%
- Purity test date: 08 March 2017
- Lot:bacth No.: WI6G16X07 after drying
- Expiration date of the lot/batch: 16 July 2018
- Appearance: Off-white to yellow crystals
- Storage: At room temperature - Key result
- Surface tension:
- 29.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: mean corrected value
- Conclusions:
- The mean surface tension of a test item solution at 1 g/L in water and at 20°C was 29.1 mN/m at 20°C.
- Executive summary:
The surface tension of the test item (= REACH substance) was determined in a GLP-compliant study performed in accordance with EC A.5 method and OECD Guideline No. 115, using the OECD harmonized ring method. The mean surface tension of a test item solution at a concentration of 1 g/L in water and at 20°C was 29.1 mN/m. According to this, the test item is considered to be surface active.

Description of key information
The surface tension of the test item (= REACH substance) was determined in a GLP-compliant study performed in accordance with EC A.5 method and OECD Guideline No. 115, using the OECD harmonized ring method. The mean surface tension of a test item solution at a concentration of 1 g/L in water and at 20°C was 29.1 mN/m. According to this, the test item is considered to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 29.1
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The surface tension of the test item was investigated in one GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.
