Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
OECD Guideline for the Testing of Chemicals No. 102 dated 27. July 1995 “Melting Point / Melting Range“
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Version / remarks:
EU-Method A.1, of 30. May 2008, published on 31. May 2008, “Melting/Freezing
Temperature”
Deviations:
no
Qualifier:
according to guideline
Guideline:
other: Regulation (EC) No 1907/2008 annex VII, column 2 of section 7.2, melting/freezing point
Version / remarks:
According to Regulation (EC) No 1907/2008 annex VII, column 2 of section 7.2, the determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20°C. Therefore, no additional test was conducted and the melting point is stated as: < - 80°C (< 193.15 K).
Deviations:
no
GLP compliance:
yes (incl. QA statement)

Remarks:
In a pre-test, the test substance linseed oil, ester with pentaerythritol was like wax but still unfrozen at – 20 and at -80°C. According to Regulation (EC) No 1907/2008 annex VII, column 2 of section 7.2, the determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20°C. Therefore, no additional test was conducted and the melting point is stated as: < - 80°C (< 193.15 K).
Conclusions:
Under study conditions, the freezing point of test substance was found to be <- 80°C (< 193.15 K).
Executive summary:

A study was conducted to determine the melting point/freezing point of the test substance, according to OECD Guideline 102 and EU Method A.1. In a pre-test, the test substance, all 3 samples of the test substance were unfrozen at – 20°C and – 80°C. According to Regulation (EC) No 1907/2008 annex VII, column 2 of section 7.2, the determination of the melting/ freezing point does not need to be conducted below a lower limit of - 20°C. Therefore, no additional test was conducted and the melting point was stated as: < - 80°C (< 193.15 K). Under study conditions, the melting point of test substance was found to be <- 80°C (< 193.15 K) (Muckle, 2017).

Description of key information

The freezing point of the test substance was determined according to OECD Guideline 102 and EU Method A.1 (Muckle, 2017).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-80 °C
