Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Administrative data
Link to relevant study record(s)
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 18 MAY 1998 - 18 MAY 1998
- Reliability:
- 1 (reliable without restriction)
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- visual inspection
differential scanning calorimetry (DSC) - GLP compliance:
- no
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- other: wax-like
- Colour:
- colourless
- Substance type:
- organic
- Conclusions:
- The test item is colourless, wax-like mass.
- Executive summary:
In a certificate of analysis, the phase-transition temperature is indicated from solid to liquid.
This is supported by the melting point study, where it is stated in the 'Presentation of the Test Item' that the appearance / physical state / colour is a colourless, wax-like mass. This was done by visual inspection.
In this study, the melting point of the test item was tested according to EU Method A.1 and OECD Guideline 102 in a non-GLP study. No exothermic effect was observed and the sample has a melting point of 51.4 °C (mean of two determinations).

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.
