Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

16/12/2014 – 23/12/2014

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: GLP accredited laboratory

Qualifier:

according to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Deviations:

no

GLP compliance:

yes

Type of method:

method to determine freezing temperature

Melting / freezing pt.:

< -20 °C

The test sample, in a clear glass vial fitted with a type K thermocouple, was placed in a circulating cooling bath over a 6 hour period. The sample temperature measured -20.2°C. The sample remained as a clear light yellow viscous liquid.

Conclusions:

Result : <-20°C
