Endpoint:
auto-ignition temperature (liquids)
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Justification for type of information:
For details and justification of read-across please refer to the report attached in section 13 of IUCLID.
Reason / purpose for cross-reference:
read-across source
Key result
Atm. press.:
969 hPa
Remarks on result:
other: No auto-ignition temperature of PURASAL S was observed until 400 °C.
Conclusions:
No self-ignition temperature of Sodium (S)-lactate was observed until 400 °C under atmospheric pressure conditions (96.9 kPa).
Executive summary:

In a GLP study conducted according to EU Method A.15, the self-ignition temperature of an aqueous solution of Sodium (S)-lactate was determined under atmospheric pressure conditions (96.9 kPa). No self-ignition temperature was observed until 400 °C.

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).

Endpoint:
relative self-ignition temperature (solids)
Data waiving:
study technically not feasible
Justification for data waiving:

Description of key information

The substance to be registered as such is a solid. However, the marketed product is an aqueous solution which cannot be transformed into a solid substance (by evaporation) due to hygroscopic properties of Sodium lactate. Thus, in accordance with REACH Annex XI, section 2, it is technically not possible to determine the relative self-ignition temperature of the solid substance.

However, a GLP study conducted according to EU Method A.15 was performed for the determination of the self-ignition temperature of an aqueous solution of the enantiomer Sodium (S)-lactate. No self-ignition temperature was observed until 400 °C.
