Sodium hydrogen N-(1-oxotetradecyl)-L-glutamate

Flash point

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Cross-reference

Cross-reference 1

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From May 10, 2016 to June 01, 2016

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: Based on another study i.e. Kintrup, 2016 (Boiling point determination).

Reason / purpose for cross-reference:

reference to same study

Principles of method if other than guideline:

The appearance, physical state and colour were visually determined.

GLP compliance:

not specified

Specific details on test material used for the study:

Batch no.: 3837

Physical state at 20°C and 1013 hPa:

solid

Key result

Form:

solid: particulate/powder

Cross-reference 2

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

Study period:

From May 10, 2016 to May 31, 2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

GLP compliance:

not specified

Type of method:

differential scanning calorimetry

Specific details on test material used for the study:

Batch no.: 3837
Appearance: white powder

Key result

Decomposition:

yes

Remarks:

probably a thermal decomposition

Decomp. temp.:

225 °C

Remarks on result:

other: atm. press.: not specified

Individual values:

225°C (from first measurement)

225°C (from second measurement)

224°C (from third measurement)

From 225°C the test substance showed most probably a thermal decomposition (a melting >225°C can't be excluded).

Conclusions:

Under the study conditions, the substance did not show any melting and underwent thermal decomposition from 225°C.

Executive summary:

A study was conducted to determine the melting point of the substance according to OECD Guideline 102. To determine the melting behaviour (three independent single measurements), the test substance was measured by DSC between -90°C and 500°C with a heating / cooling rate of 10 K/min in 4 cycles. For the measurement a capsulated crucible was used. Under the study conditions, the substance did not show any melting and underwent thermal decomposition from 225°C (Kintrup, 2016).
