Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 2009-10-15
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Determination has been run accordingly to standardized method but without GLP compliance.
- Justification for type of information:
- Refer to read-across justification document in section 13
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- OECD harmonised ring method
- Surface tension:
- 32 mN/m
- Temp.:
- 23 °C
- Conc.:
- 1 g/L
- Conclusions:
- The CMC is determined to 19 mg/L at pH 7. Also, the surface tension at 1 g/L solution has been determined at pH 7 to 32 mN/m.
Reference
The CMC is determined to 19 mg/L at pH 7. Also, the surface tension at 1 g/L solution has been determined at pH 7 to 32 mN/m.
Description of key information
Study carried out on 68555 -22 -6 used for read-across to 85029 -55 -6 based on structural or surrogate analogue.
The surface tension is determined to be 32.0mN/m at 20°C and at a concentration of 1000mg/L
Key value for chemical safety assessment
- Surface tension:
- 32
- in mN/m at 20°C and concentration in mg/L:
- 1 000
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.
