Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Study not performed according to a guideline, but materials & methods and results are well described.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The surface tension was measured with a thermostated tensiometer (Digital Tensiometer K 10ST, Kru¨ss Gmbh, Germany) using a Wilhelmy plate method.14 The temperature was set to 25 °C and controlled with a circulation liquid path (Lauda RC6 CS). The oxalic acid was dissolved in water. Water was purified to ultrapure quality (Milli-Q, 18 M).
- GLP compliance:
- not specified
- Type of method:
- plate method
- Key result
- Surface tension:
- ca. 70.1 mN/m
- Temp.:
- 25 °C
- Conc.:
- 0.015 other: molar fraction
- Conclusions:
- Surface tension of the substance is not lower than 60 mN/m, then oxalic acid should not be regarded as being surface-active
materials.

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.
