Applicant's summary and conclusion
- Conclusions:
- In a study conducted according to guideline no melting point was found.
- Executive summary:
The melting point of Neodecanoic acid, tin(2 +) salt (2:1) was investigated in a study conducted according to OECD Guideline 102 (Melting point / Melting Range) and EU Method A.1 (Melting / Freezing Temperature) using the DSC method.
According to the visual inspection, Zinn-Neodekanoat liquefies at 14 °C.
Within the first heating period of the DSC test, no according endothermic signal was recorded
over a temperature range of approximately - 90 °C … 60 °C, however, a glass transition could be
identified at -60.2 °C. This glass transition was reproducibly detected in the subsequent heating
cycle as well as in repeated tests.
Due to the missing phase transition effect one can conclude that the observed liquefaction at
14 °C is not related to a melting behaviour but to viscosity drop without phase transition (setting
point).
