Reference
Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2006-10-13
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study
Remarks:
The pendant drop method used in this study is comparable to the ring method OECD 115 since good correlation has been identified.
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
Pendant drop method used
Deviations:
yes
Remarks:
pendant drop model used
Principles of method if other than guideline:
The surface tension analyses on water solutions were performed with a contact angle meter instrument according to the principle pendant drop. An internal method (A1577) was used. The results from this method have been compared with results obtained with the ring method described in guideline OECD 115. Good correlation was found between the pendant drop method (A1577) and the ring method.
GLP compliance:
no
Type of method:
other: Pendant drop
Specific details on test material used for the study:
- Analytical purity: > 98% GC purity
- Lot/batch No.: 561058
- Storage condition of test material: room temperature
Key result
Surface tension:
72 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
The surface tension of Bis-MPA is 72 mN/m at 20°C (not surface-active).
Executive summary:

Using the pendant drop method, which was shown to be in good correlation to the ring method described in OECD 115, the surface tension of Bis-MPA was determined as 72 mN/m at 20 °C.
