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:

30 November to 2 December 2021

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Justification for type of information:

A non-GLP study was conducted according to protocol developed by fragrance industry. The substance is adequately identified. Therefore full validation applies.

Qualifier:

equivalent or similar to guideline

Guideline:

other: According to guideline EFFA/EFEO guideline "The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients"

Deviations:

no

Principles of method if other than guideline:

The test substance is a mixture of substances and transition from liquid to solid will not be sharp.
The EFFA/EFEO guideline "The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients”, reccommends to describe the state of the an essential oil after two days at +5°C and -20 °C rather than determining a transition temperature.

GLP compliance:

no

Type of method:

other: visual observation

Melting / freezing pt.:

< -20 °C

Remarks on result:

other: Experimental Pressure non specified but supposed to be the atmospheric pressure

After 24 hours (and even 43 hours) of freezing, the test item was still liquid as on the first day.

Maximum recorded temperature: -20.00°C

Minimal recorded Temperature: -22.31°C

Average Temperature: -21.16 °C.

Conclusions:

The freezing point of the test susbtance was stated to be lower than -20ºC.

Executive summary:

A non-GLP experimental test was conducted according to the methodology proposed by the EFFA/EFEO guideline "The Registration for REACH of Natural Complex Substances used as Fragrance Ingredients”. By visual observation it was found that the test item was a mobile liquid at 20ºC and a mobile liquid after 43 hours at -21.16ºC (average registered temperature). Therefore, it was concluded that the freezing point of the test susbtance was lower than -20ºC.

Description of key information

The freezing point of test substance is stated to be lower than -20°C.

Additional information

A fully reliable experimental study is available, based on observation at given temperature (-20°C), as recommended for NCS: the substance remained liquid at the temperature tested.
