Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- The study was conducted between 03 January 2019 and 05 February 2019.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Specific details on test material used for the study:
- Identification: PG-RAW-0004
Appearance/physical state: clear, colorless liquid
Storage conditions: approximately 4 °C in the dark - Key result
- Surface tension:
- 56.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % Saturated solution
- Conclusions:
- The Surface Tension of PG-RAW-0004 has been determined to be 56.5 mN/m at 20°C according to OECD TG 115 (Surface Tension of Aqueous Solutions) using the ring method in compliance with GLP. According to EU method A.5, the substance is considered to be surface active because the value is less than 60 mN/m.
- Executive summary:
The Surface Tension of PG-RAW-0004 has been determined to be 56.5 mN/m at 20°C according to OECD TG 115 (Surface Tension of Aqueous Solutions) using the ring method in compliance with GLP. According to EU method A.5, the substance is considered to be surface active because the value is less than 60 mN/m.
