Decan-4-olide

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:

12/2007 to 03/2008

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study without detailed documentation

Remarks:

The study was conducted according to an internationally recognised method. The substance is adequately defined (with certificate of analysis). However, some experimental data are missing. Therefore validation applies with restrictions.

Qualifier:

according to guideline

Guideline:

other: ASTM D87-87

Qualifier:

equivalent or similar to guideline

Guideline:

other: BS 4695

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

GLP compliance:

no

Type of method:

method to determine freezing temperature

Specific details on test material used for the study:

Sample storage: under nitrogen atmosphere and protected from light

Melting / freezing pt.:

< -20 °C

Remarks on result:

other: accuracy: +/-0.5 °C

No data on individual measurements (at least two repetitions required).

Conclusions:

The freezing point of the test substance is less than -20°C.
No further testing is required.

Executive summary:

According to ASTM D87-87 guideline (equivalent to OECD/EC), no freezing point of the test material was observed down to a temperature of -20°C.

Description of key information

Freezing point < -20 °C

No further testing required.

Additional information

A reliable study, conducted according to a method equivalent to OECD/EC, is available. Therefore, it is considered as a key study. As no freezing was observed down to -20°C, the result is expressed as a limit value, and cannot be retained as key data for purpose of CSA.
