Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 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:
- A standardized test for the surface tension of lactic acid resulted in the determination that a 1g/L solution of lactic acid in water has a surface tension of 70.7 mN/m; at this surface tension, it can be concluded that lactic acid is not a surface active substance.
- Executive summary:
The OECD harmonized ring method 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 20.0 °C was 70.7 mN/m. According to this, the test substance is considered not to be surface active.
This information is used in a read-across approach in the assessment of the target substance.
For details and justification of read-across please refer to the attached report in section 13 of IUCLID.
