Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -29.51 °C
Additional information
The melting point of the relevant constituents of Depanol I were calculated using the international accepted QSAR tool EPI WIN v3.20 using the module MPBPWIN v1.42.
This information is considred to be Klimisch 2 information. The calculated melting points were (sequence according to the percentual share in Depanol I):
-40,76 °C for Dipentene (Cyclohexene, 1 -methyl-4 -(1-methylethenyl)-; CAS 138 -86 -3)
-29.51°C for Terpinolene (Cyclohexene, 1 -methyl-4 -(1 -methylethylidene)-CAS 586 -62 -9)
-31.15 °C for alpha Terpinene (1,3 -Cyclohexadiene, 1 -methyl-4 -(1 -methylethyl)-; CAS 99 -86 -5)
-31.15 °C for gamma Terpinene (1,4-Cyclohexadiene, 1-methyl-4-(1-methylethyl)-; CAS 99 -85 -4).
Since the calculations were performed using an international accepted QSAR tool where reference data and calibration sets are available and the substance falls within the applicability domain, the obtained results are considered reliable and relevant for the risk assessment according to REACH Annex XI section 1.3.
Since the major constituents of Depanol I were considered, the melting range of -40.76 to -29,51°C as determined for the ingredients is considered to be relevant also for the final product. The highest melting point, i.e., -29,51°C will be used for the risk assessment.
According to REACH Annex VII Section 7.2 column 2 "The study does not need to be conducted below a lower limit of -20 C".
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.
