Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:

- Study period:
- The study was conducted between 27 November 2017 and 27 November 2017.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:

- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- GLP compliance:

- Type of method:
- ring method
- Specific details on test material used for the study:
- Batch/Lot number: 2161004
Appearance: White to light yellow flakes
Purity: 99.41%
Expiry date: 31 January 2018
Storage conditions: Controlled room temperature (15-25°C, below 70RH%), protected from light
Safety precautions: Routine safety precautions (lab coat, gloves, safety glasses, face mask) for unknown materials were applied to assure personnel health and safety. - Key result
- Surface tension:
- 72 mN/m
- Temp.:
- 21 °C
- Remarks on result:
- other: Concentration not available.
- Conclusions:
- The surface tension of the test item aqueous solution read on the instrument was 70.7 mN/m at 21±0.5 °C using the ring method representing the mean of five separate measurements.
The measured surface tension was multiplied by ϕa resulting in a corrected surface tension of 72.0 mN/m. - Executive summary:
The determination of the surface tension was carried out on the test item, with the use of a Krüss K11 Tensiometer by ring method. The value was found to be 72.0 mN/m.
As the surface tension value was higher than 60 mN/m, NIPAM is not classified as surface active.
Reference
The surface tension of the test item aqueous solution read on the instrument was 70.7 mN/m at 21±0.5 °C using the ring method representing the mean of five separate measurements. The measured values were corrected with Harkins-Jordan correction factor.
The measured surface tension was multiplied by ϕa resulting in a corrected surface tension of 72.0 mN/m.
As the surface tension value was higher than 60 mN/m, NIPAM is not classified as surface active.

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.
