- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1999-06-22 to 1999-06-25
- Reliability:
- 1 (reliable without restriction)

- Deviations:
- not specified
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:

- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- -33 °C
- Remarks on result:
- other: Atmospheric pressure not specified
- Conclusions:
- The freezing temperature of SANTICIZER 2148 Plasticizer was determined to be -33°C.
- Executive summary:
The determination of the freezing temperature of SANTICIZER 2148 Plasticizer was based on EEC-Directive 92/69 EEC, A.1 ‘Melting/Freezing temperature (1992) and on OECD Guideline no. 102 ‘Melting Point/Melting Range’ (1981).
In a duplicate experiment, the freezing temperature of SANTICIZER 2148 Plasticizer was determined to be -33°C.

2 tests were conducted during the main study
Test 1: the test substance became cloudy at a temperature of about 25°C (248K). at a temperature of -32°C (241K) the test substance became solid and the temperature increased to about -14°C
Test 2: the test substance became cloudy at a temperature of about -25°C (248K). at a temperature of -34°C (239K) the test substance became solid and the temperature increased to about -10°C (263K). The temperature rise was believed to cause by the exothermic effect of the solidification. The temperature fall was <5K/min
In conclusion, the freezing temperature of SANTICIZER 2148 Plasticizer was determined to be -33°C.

Additional information
A key OECD Guideline 102 study was conducted to determine the freezing temperature of SANTICIZER 2148 Plasticizer (NOTOX B.V., 1999a)
In a duplicate experiment, the freezing temperature of SANTICIZER 2148 Plasticizer was determined to be -33°C.
