Batch AD19K01750
Purity : 100% (UVCB)
Expiry date : 27/07/2021 - Key result
- Melting / freezing pt.:
- > 400 °C
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 250 °C
- Remarks on result:
- other: the test item became black
- Conclusions:
- The test item has no melting point up to 400°C and degradation of test item appears at about 250°C.
- Executive summary:
The melting point was determined according to the method A.1 of the Commission Regulation (EC) No 440/2008 of 30 May 2008 and in compliance with the GLP, using the Differential Scanning Calorimetry method (DSC).
No melting point of the test item was recorded up to 600 °C in the 1st assay and up to 400°C in the second assay.
The degradation of the test item (exothermic peak) occurs at about 250°C. The aspect of the test item changed in compact black block.
The test item, Saccharomyces cerevisiae cell wall, extracted, has no melting point up to 400°C.
This melting point study is classified as acceptable, and satisfies the guideline requirements of the EU method A.1.
Reference
No melting point of the test item was recorder up to 600 °C in assay 1 and up to 400°C in assay 2. In the both assays, an exothermic peak (decomposition) was observed at about 250 °C. The aspect of the test item changed in compact black block.
Description of key information
The test item has no melting point up to 400°C and degradation of test item appears at about 250°C.
Key value for chemical safety assessment
