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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- melting point/freezing point
- Type of information:
- experimental study

- key study
- Study period:
- 26.07.2005 - 13.12.2005
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- GLP.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- December 1992
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Key result
- Remarks on result:
- other: The DSC-curve shows no sign of a melting peak, but an endothermic cp-step at -109 °C, characteristic for a glass transition, i.e. the test item solidifies amourphously.
- Conclusions:
- No melting point of Butyldiglycol methacrylate could be determined by differential scanning calorimetry but an endothermic cp-step at -109 °C; characteristic for a glass transition, i.e. the test item solidifies amorphously. Therefore a melting point <-20 °C is adopted for Butyldiglycol methacrylate.
- Executive summary:
No melting point of Butyldiglycol methacrylate could be determined by differential scanning calorimetry but an endothermic cp-step at -109 °C; characteristic for a glass transition, i.e. the test item solidifies amorphously. Therefore a melting point <-20 °C is adopted for Butyldiglycol methacrylate.

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.
