Executive summary:

The flash point was of the test item was determined according to EN ISO 3679. For ignition a natural gas flame was used. No ignition was observed visually. The sample was tempered to 5 °C for the test according to EN ISO 3679.

The given value is the mean of 3 measurements.

No flash point could be determined for the test item.

The investigations have been carried out at the following ambient conditions:

- Ambient temperature: 29 °C

- Ambient pressure: 100.7 kPa

Description of key information

The flash point of lactic acid (CAS 50-21-5) was determined by method EN ISO 3679. For ignition a natural gas flame was used. No ignition was observed visually. Thus, no flashpoint could be determined for the test item.

Key value for chemical safety assessment
