- Executive summary:
The boiling temperature of Amphopropionates C12 -18 (96.3% a.i.) was determined by thermogravimetry and differential scanning calorimetry according to OECD Test Guideline 103 (adopted on 27 July 1995) and EU test method A.2. There was no boiling point detected. Test item decomposition was observed above 190 °C.

Results
TGA
In the TGA test, a sample of the test item was heated from 30 °C to 675 °C in an inert gas atmosphere (N2). Between 30 °C and 150 °C it lost 2.95 % of its weight, which can be mainly attributed to the evaporation of residual water.Above 189 °C (onset) the weight continuously decreased and reached a loss of approx. 95 % at 560 °C.
DSC
An endothermic signal was recorded over a temperature range of -29 °C - 8 °C. No additional phase transition could be observed up to 190 °C. This endothermic is possibly attributed to a solid-solid phase transformation, however, a melting of crystalline subcomponents cannot be completey excluded. The recorded discontinuities above 150°C indicate a beginning decomposition of the test item which corresponds to the increased weight loss (11.7%).
Description of key information
no boiling point detected, decomposition >190°C (OECD TG 103 / EU methdo A.2; RL1; no GLP)
Key value for chemical safety assessment
Additional information
The boiling temperature of Amphopropionates C12 -18 (96.3% a.i.) was determined by thermogravimetry and differential scanning calorimetry according to OECD Test Guideline 103 (adopted on 27 July 1995) and EU test method A.2. There was no boiling point detected. Test item decomposition was observed above 190 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
