Melting point / freezing point

Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: Guideline study performed under GLP. All relevant validity criteria were met.

Qualifier:

according to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Deviations:

no

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Deviations:

no

Principles of method if other than guideline:

The determination was carried out using a pour point procedure designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008, and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

GLP compliance:

yes (incl. QA statement)

Remarks:

inspected: June 2015; signature: September 2015

Type of method:

capillary method

Melting / freezing pt.:

< 253 K

Atm. press.:

1 atm

Decomposition:

no

Sublimation:

no

Remarks on result:

other: < -21 ± 3 °C (pour point)

Measured temperatures were converted from °C to K using T = t + 273.15

T = temperature (K)

t = temperature (°C)

Preliminary test:

The pour point of the preliminary test was less than -20°C (<253 K)

Definitive test:

Overall pour point result; mean (n=2) : less than -21°C (<252 K)

Stationary point was determined to be < -24°C (< -255 K) in duplicate.

Conclusions:

The pour point of the substance has been determined to be less than 252 ± 3 K or < -21 ± 3 °C. The melting point/freezing point is less than 253 K or < -20°C.

Executive summary:

The pour point temperature of the test substance was determined using EU Method A.1 and OECD TG 102 capillary method under GLP. Following preliminary testing in a definitive test performed in duplicate the pour point was determined less than -21 °C (< 252 K). Applicant assessment indicates since the test substance was observed to flow as a liquid at temperatures > -20 °C; the test item melting point/freezing point can be considered to be < -20 °C. At temperatures greater than or equal to -20 °C (or 253 K) the test substance is a liquid at atmospheric pressure.

Additional information

Key study: EU Method A.1, 2016 : The pour point temperature of the test substance was determined using EU Method A.1 and OECD TG 102 capillary method under GLP. Following preliminary testing in a definitive test performed in duplicate the pour point was determined less than -21 °C (<252 K). Applicant assessment indicates since the test substance was observed to flow as a liquid at temperatures > -20 °C; the test item melting point/freezing point can be considered to be < -20 °C. At temperatures greater than or equal to -20 °C (or 253 K) the test substance is a liquid at atmospheric pressure.
