Decomposition:
yes
Decomp. temp.:
>= 45.51 °C
Remarks on result:
not determinable
Remarks:
No boiling point can be determined because of decomposition of the test item after melt-ing.

Applicant's summary and conclusion

Conclusions:
No boiling point can be determined because of decomposition of the test item after melting.
Beginning of decomposition, evaluated with the event marker, was determined under these circumstances as: 45.51 °C (318.66 K) (lowest value)
Executive summary:

The determination of the boiling point study of Palmitoyl grapevine shoot extract was performed via DSC (differential scanning calorimetry).

No boiling point can be determined because of decomposition of the test item after melting.

Beginning of decomposition, evaluated with the event marker, was determined under these circumstances as:

45.51 °C (318.66 K) (lowest value)
