Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance, as distributed in commerce, is a waxy solid containing 40% oil which begins to liquify at 85.9 deg. C. The flash point of the de-oiled, substance is 177 deg. C as determined by ASTM D93 (Pensky-Martens closed cup method).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 177 °C
Additional information
The results of four tests showed flash points ranging from 57 – 177 deg. C with only one test result giving a flash point of 57 deg. C and three tests showing flash points of > 150 deg. C.
The low flash point measurement of 57 deg. C has been traced to residual solvent (heptane) used for de-oiling the test substance. This result was not reproduced in subsequent tests. The reliability of this previously submitted study has been revised to R3.
A key study has been identified which shows the flash point of the substance is 177 deg. C. This result is consistent with two additional tests (identified as supporting studies) on two different batches, of the substance which showed flash points of > 150 deg. C and > 220 deg. C. Based on the results obtained for three of the four studies, a flash point value of 177 deg. C is considered to provide a more reliable indication of the flammability of the substance.
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.
