Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study performed under GLP.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- plate method
- Surface tension:
- 63.77 mN/m
- Temp.:
- 25 °C
- Conc.:
- 400 mg/L
- Remarks on result:
- other: Saturated solution
- Conclusions:
- Study is considered adequate and reliable. Surface tension is >60mN/m, therefore not considered to be surface active substance (according to EU method A5). Note: mistake in reported concentration units corrected (ca. 0.04g instead of the reported "ca. 0.4g in 100mL").
Reference
Average of 5 experiments: 61.66mN/m, 63.15mN/m, 65.56mN/m, 64.38mN/m, 64.11mN/m.
Description of key information
63.77 mN/m, 25±1 °C, ca. 400 mg/L, Wilhelmy Plate, EU Method A.5, Kennedy 1999
Key value for chemical safety assessment
- Surface tension:
- 63.8
- in mN/m at 20°C and concentration in mg/L:
- 400
Additional information
Only a single study conducted according to guidelines and under GLP is available for this endpoint. The study is considered to be relevant, reliable (Klimisch 1) and adequate for the purposes of risk assessment, classification and labelling.
According to the criteria laid out in EU Regulation No. 440/2008, A5, the substance is not considered to be surface active, because the aqueous surface tension is >60 mN/m.
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.
