Sodium zirconium lactate

Vapour pressure

Administrative data

Endpoint:

vapour pressure

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the melting point is above 300°C

Justification for type of information:

No melting point determined, with decomposition > 300 C
Evidence suggests that continued heating will lead to formation of oxides of zirconium and sodium with decomposition of the lactate

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

comparable to guideline study

Justification for type of information:

Assessment by manufacturer using recognised methods

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Principles of method if other than guideline:

Melting Point device MPD02 up to 300 C

GLP compliance:

no

Type of method:

capillary method

Atm. press.:

ca. 1 atm

Decomposition:

yes

Decomp. temp.:

> 300 °C

Remarks on result:

not determinable

Executive summary:

No melting was observed when substance was analysed with Melting Point device MPD02 up to 300 C.

Thermogravimetric analysis was also performed and it was observed that between 100 °C. – approx. 400 °C the substance suffers a further dehydration process, followed most likely, by the decomposition of the sodium lactate ligand (organic part).

Oxidation will occur at higher temperatures

During normal use and handling, and certainly under biological and environmental conditions, there substance will remain solid.
