- 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:
- 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 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:
- 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.

Description of key information
Lactic acid is not surface active.
Key value for chemical safety assessment
- Surface tension:
- 70.7
- in mN/m at 20°C and concentration in mg/L:
- 1
Additional information
A standardized test conducted according to OECD TG 115 resulted in the determination that a 1 g/L solution of lactic acid in water has a surface tension of 70.7 mN/m. Based on the results, it can be concluded that lactic acid is not a surface active substance.
