Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:

- Type of method:
- method to determine freezing temperature
- Remarks:
- freezing assessed visually
- Melting / freezing pt.:
- < -20 °C
- Remarks on result:
- other: No further information was provided.
- Conclusions:
- The testing was performed to a minimum temperature of -20°C. The substance remained a liquid, despite being seeded with frozen sample from the -80°C weighing and left for 24 hours. The melting/freezing point was therefore reported as <-20°C.
- Executive summary:
The melting point of the test substance was determined in accordance with the EU Testing Method A.1. The melting point was determined by weighing out three lots of 1 g of sample and placing at either 4°C, -20°C or -80°C. The samples were left for 24 hours and assessed visually to see whether they had frozen. After the first check only the -80°C sample had frozen. The -20°C was seeded with some -80°C sample and left for a further 24 hours. After the second 24 hour period the -20°C sample was still liquid. As the freezing point was found to be between -20°C and -80°C no further testing was conducted and the melting/freezing point was therefore reported as <-20°C.
Reference
After 24 hours the samples were checked visually to see whether they had frozen or not. On the first check it was found that only the -80°C weighing had frozen. It was decided to seed a -20°C sample with some frozen samples from the weighing kept at -80°C. This was left for another 24 hours after which it was found to still be unfrozen. As the freezing point was found to be between -20°C and -80°C no further analysis was carried out and the freezing point was reported as <-20°C.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
