Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
GLP compliance:
yes
Type of method:
method to determine freezing temperature
Specific details on test material used for the study:
Component of a Polyurethane System
Polyoxypropylene triamine
(39423-51-3) 60-100%
Melting / freezing pt.:
< -20 °C

The sample was tested at -20°C. There were no signs of freezing. The sample remained a colourless, free-flowing liquid.

Conclusions:
The substance was tested at -20°C. There were no signs of freezing. The sample remained a colourless, free-flowing liquid. The freezing point of the test material is therefore considered to be < -20 °C.

Description of key information

The freezing point of the test substance was determined to be <-20 °C, following EU test method A.1 to determine the freezing temperature (Baker, 2010). 

Key value for chemical safety assessment

Additional information

The sample was tested up to the lower limit as set out in column 2 of the REACH regulation on standard information requirements (Annex VII) at which no signs of freezing were observed. At -20°C, there were no signs of freezing. The sample remained a colourless, free-flowing liquid.
