Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 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:
- plate method
- Surface tension:
- 64.92 mN/m
- Temp.:
- 19 °C
- Remarks on result:
- other: saturated solution of the test item in water
- Conclusions:
- In a GLP-study according to OECD Test Guideline 115, the surface tension of the registered substance was determined as 64.92 ± 0.48 mN/m at 19.9 °C.
- Executive summary:
The surface tension of an aqueous solution of CARDOLITE NC-513 according to OECD 115 resp. EU A.5 was determined as 64.92 ± 0.48 mN/m at 19.9 °C. One measurement was performed for verification purposes (after 59 minutes). No relevant changes and thus no dependence of surface tension on time were observed.
As all measured values were higher than 60 mN/m, the test item CARDOLITE NC-513 was classified as not surface active.
The surface tension of the negative control lay within the accepted range. The concentration of the 90 % saturated test solution was determined with 7.71 mg test item/L via DOC measurement.

Additional information
In a GLP-study according to OECD Test Guideline 115, the surface tension of the registered substance was determined as 64.92 ± 0.48 mN/m at 19.9 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
