Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

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).

Description of key information

In conclusion, it can be stated that under the conditions described 1 g/L of Lactic acid 93% has a surface tension value at 20 °C of 70.7 mN/m. Therefore, Lactic acid 93%  is considered as not surface active.
