Any other information on results incl. tables
The test item started to change its colour from blue to brown at about 210 °C. At about 220 °C colour change was completed. There was no melting point observed in the temperature range of 30 – 400°C. The test item decomposed.
Results with reference substance: melting point of 236.7 °C was found for caffeine, which is conform the CoA.
Applicant's summary and conclusion
- Conclusions:
- There was no melting point observed in the temperature range of 30 – 400°C. The test item decomposed at 210°C.
- Executive summary:
The test was carried out according to OECD guideline 102 and EC method A.1. Capillary tubes filled with the test item were heated in a metal block. The test item decomposed at about 210 °C and no melting point was observed in the range of 30 – 400 °C.
