EC number: 700-759-4 | CAS number: -
Surface tension
Administrative data
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- The reliability is rated 2 because the method of the study is similar to the standard guideline of reference (OECD 115), which describes a procedure designed to evaluate this endpoint. The results were reviewed for reliability and assessed as valid. Study not conducted under GLP conditions.
