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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
- melting point: -80°C (EU Method A.1 and ASTM D 1177-12);
- relative density: 1.425 g/cm³ (1.424 – 1.425 g/cm³) (pycnometer method of EU Method A.3 and ASTM D 153-84);
- n-octanol/water partition coefficient: Log Pow 3.03 ± 0.27 (OECD Guideline 117);
- water solubility: 30 mg/L (shake flask method of EU method A.6);
- flash point: 75°C (PMCC method of ASTM D93); and
- autoignition temperature: 408°C (ASTM E659).
- particle size distribution: the substance is marketed or used in a non-solid or granular form (i.e., the substance is a liquid);
- surface tension: surface activity is not a desired property of the material;
- substances/mixtures which in contact with water emit flammable gases: experience in production or handling shows that the substance does not react with water;
- pyrophoric liquids: the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied;
- explosiveness: there are no chemical groups present in the molecule which are associated with explosive properties; and
- oxidising liquids: there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied.
OFPMA is a colourless liquid at 20°C and 1013 hPa. The following physical-chemical results were obtained at standard atmospheric pressure and temperature following guideline methods:
The boiling point of OFPMA was determined following a non-guideline distillation method and was reported to be 180.5°C at standard atmospheric pressure. The vapour pressure of OFPMA was determined following a non-guideline vapour-liquid equilibrium method similar to the static method. The measured values were corrected using the residual pressure recorded at absolute zero; however, in theory, the pressure would increase with temperature. This deviation is not anticipated to have a significant effect on reported value. The vapour pressure of OFPMA is approximately 1241 Pa at 25.5°C.
It is technically not feasible to conduct the flammable solids and flammable gases studies because the substance is a liquid.
It is scientifically not necessary to conduct the following studies:
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.
