Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
July 1995
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Version / remarks:
May 2008
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
< -80 °C
Remarks on result:
not determinable

Pre-test results:

Room temperature: Clear, slightly yellow, slightly viscous liquid.

4.2°C: A bit more viscous then at reoom temperature.

-21.9°C: Not flowable anymore, but easily piercable with a long thin wire.

-80°C: Solid, but piercable (with pressure), like wax.

According to Annex VII, column 2 of EU regulation 1907/2006 (REACH), the study does not need to be conducted below a lower limit of -20°C. Hence, the main study was not performed, and the melting point is reported to be <-80°C.

Conclusions:
The melting point of the Oligomerisation product obtained by plasma treatment of vegetable oil mono- and polyunsaturated C16-C22 triglycerides was found to be <-80°C.
Executive summary:

The melting point of the Oligomerisation product obtained by plasma treatment of vegetable oil mono- and polyunsaturated C16-C22 triglycerides was examined in accordance with OECD guideline 102 and EU guideline A.1. In a pre-test, the test item was partially but not completely frozen at – 80 °C. At this temperature, the test item was solid, but wax-like and piercable when the surface was touched (with pressure) with a thin wire.

According to Annex VII, column 2 of EU regulation 1907/2006 (REACH), the study does not need to be conducted below a lower limit of -20°C. Hence, the main study was not performed, and the melting point is reported to be <-80°C.
