- Executive summary:
In accordance with OECD guideline for Research Chemicals (Method 102) and GLP study the determination of freezing point was carried out. The test item was tested in a liquid form (as supplied) using method of crystallization tube in freezing mixture ice/acetone. The tube was coated with an outed tube and whole set was placed in a Dewar vessel with freezing mixture.The freezing temperature was determined during the four measurement (preliminary test and main tests). As in the preliminary test temperature growth exceeded 2°C (supercooling process), main tests were carried out with a small amount of crystallization seeds in a liquid sample in order to avoid an excess supercooling. The freezing temperature was read with accuracy of 0.1 ºC. The average value of an initial freezing point of test item is equal to 16.0 ± 0.1°C.
