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
- Justification for type of information:
- For details and justification of read-across please refer to the read-across report attached to IUCLID section 13.
- Reason / purpose for cross-reference:
- read-across source
- Key result
- Surface tension:
- 70.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- In conclusion, it can be stated that under the conditions decribed 1 g/L of Lactic acid 93% has a surface tension value at 20 °C of 70.7 mN/m. Therefore, lactic acid 93% aq is considered as not surface active.
- Executive summary:
The OECD harmonized ring method (OECD TG 115) was used for the determination of the surface tension of Lactic acid 93% aq. The surface tension of a test solution at a concentration of 1 g/L and at 20 °C was 70.7 mN/m. According to this, the test substance is considered as not surface active.
This information is used in a read-across approach in the assessment of the target substance. For justification of read-across please refer to the attached read-across report (see IUCLID section 13).
