Study period:

May - September 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Version / remarks:

1995

Qualifier:

according to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

GLP compliance:

yes (incl. QA statement)

Type of method:

method to determine freezing temperature

Remarks:

Specific details on test material used for the study:

Batch number: 83100001
Purity: 91.1%
Physical state/appearance: Clear colourless liquid
Expiry date: 11 May 2018
Storage conditions: Room temperature (nominally 15 to 25C), dark

Key result

Melting / freezing pt.:

< -20 °C

Conclusions:

In a preliminary determination, the test item did not solidify as the temperature was decreased from ambient temperature down to below -20°C. No further testing was necessary. The freezing temperature of alpha-Terpinene was determined to be less than -20°C.

Executive summary:

The freezing temperature of alpha-terpinene was determined to be less than -20°C according to the OECD TG 102 and EU Method A.1.

Description of key information

Key study: Test method according to OECD TG 102 and EU Method A.1, GLP study. The freezing temperature of alpha-terpinene was determined to be less than -20°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
