- Specific details on test material used for the study:
- - Trade name: Purasolv EL
- Batch number: 0909001195
- Appearance: Clear colourless liquid
- Purity: 99.83 % w/w
- Storage: at room temperature, in the dark under nitrogen
- Expiry date: 2010-09-14 - Key result
- Surface tension:
- 70.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of a test solution at a ethyl (S)-lactate concentration of 1 g/L in water at 20 °C was 70.5 mN/m. The test substance is considered not to be surface active.
- Executive summary:
The OECD harmonized ring method was used for determining the surface tension of PURASOLV®EL (ethyl-(S)-lactate). The surface tension of a test solution at a ethyl-(S)-lactate concentration of 1 g/L in water at 20 °C was 70.5 mN/m. The test substance is considered not to be surface active.

Description of key information
The OECD harmonized ring method was used for the determination of the surface tension of PURASOLV®EL (Ethyl (S)-lactate). The surface tension of a test solution at a Ethyl (S)-lactate concentration of 1 g/L in water at 20 °C was 70.5 mN/m. The test substance is therefore considered as not surface active.
Key value for chemical safety assessment
- Surface tension:
- 70.5
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
