Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- 2008
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Suga Nate 160NC and SugaNate 100NC can exist as waxy solid , but the melting point of the isolated material have not been determinated accurately. It is envisaged that the 100% product will melt somewhere in the region of 250 ªC
- Justification for type of information:
- SugaNate 160NC has been used in this end point as a read-across substance for SugaNate 100NC. A comparison of the two substances and a read-across justification can be found in section 13 of this dataset.
- Qualifier:
- according to guideline
- Guideline:
- other: freezing point depressio theory

Description of key information
SugaNate products are generally manufactured and marketed in aqueous solution. Removal of the water results in the production of a waxy solid, which is difficult to handle in traditional melting/boiling point test methods and attempts at DSC / TGA were not succesful and the melting point of the isolated materials have not been determinated accurately.The attempt to use DSC to measure the melting point of SugaNate 160NC resulted in a trace that did not show any indication of melting point during the test which scanned from 180 - 280 deg C. Further attempts are planned.
It is envisaged that the 100% product will melt somewhere in the region of 250 deg C. The use of EPIsuite and the SMILES notation of these two products suggests that SugaNate 100NC will have a M.Pt of 267 deg C and SugaNate 160NC will have a M Pt of 288.5 deg C, which is in good agreement with the manufacturer's own assessment.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 250 °C
Additional information
The freezing point of the 40% solution as sold arround -5ºC.
