Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The key study (Sárvári, 2012g) was performed under GLP conditions and in accordance with standardised guidelines. The study was assigned a reliability score of 1 in line with the principles for assessing data quality as defined by Klimisch (1997). Under the conditions of the study, the test material was determined to be non-flammable.

The supporting study (Atwall, 2008) was performed using information on the read across substance, sodium 5-oxo-DL-prolinate, which is a racemic mixture of the D- and L- isomeric forms of the substance. Read-across is considered to be suitable based on the structural similarities between the supporting substance (sodium 5-oxo-DL-prolinate) and the substance to be registered (sodium 5-oxo-L-prolinate), which is the L- isomer only. As such the difference in isomeric forms of the substance is unlikely to affect the physico-chemical properties. The study was conducted under GLP conditions and in accordance with standardised guidelines. The study was assigned a reliability score of 2 in line with the principles for assessing data quality as defined by Klimisch (1997). Under the conditions of the study, the test material was determined to be non-flammable, supporting the findings presented in the key study.

In accordance with Section 2 of Regulation (EC) No. 1907/2006 (REACH) Annex XI, it is considered justified to omit the Flammability (Contact with Water) study and the Flammability (Pyrophoric Properties) study (both further required in Section 7.10) as there is no evidence based on its chemical structure, and experience in handling, that the substance will either spontaneously ignite in air at room temperature or exhibit flammable properties in contact with water.

Justification for classification or non-classification

According to the criteria outlined in Regulation (EC) No. 1272/2008, the test material does not meets the criteria for classification as a flammable substance.
