Executive summary:

The melting temperature of the test substance, Semi Dry Absorption (SDA) Product was determined. The Differential Scanning Calorimetry method was used.

The procedures used in the study were in accordance with:

Method A.1. Melting/Freezing temperature, Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008

OECD Test Guideline No.102, Melting Point/Melting Range, Adopted July 27, 1995

Definite value of melting temperature of the test substance, Semi Dry Absorption (SDA) Product, could not be determined in the tested temperature range from 35 to 640°C.

Thermal degradation of the test substance connection with the lost of the mass started at the temperature 50°C.

Description of key information

Method A.1 Melting/Freezing temperature, Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008.

GLP study.

No endothermic peak corresponding to melting of the test substance was recorded in the tested temperature range from to. Thermal degradation of the test substance connection with the lost of the mass started at the temperature 40°C. Definite value of melting temperature of the test substance could not be determined in the tested temperature range from 35°C to 640°C.

Key value for chemical safety assessment
