Description of key information
The registered UVCB substance " Stearic acid, monoester with propane-1,2-diol" (PGMS) is a paste-like solid at room temperature. It melts at about 41.1 -42.6°C and has a boiling point of 397°C. It has a density of 0.93 at 20°C, i.e., slightly below water density. The partition coefficient was calculated using EpiSuite (US EPA Epi Suite v4.0) showing a logPow for the test substance of 7.67. It has a very low solubility in water with a calculated water solubility of 0.006205 mg/L. Due to the very low solubility in water (<<1mg/L) it was not possible to measure the surface tension. The shear viscosity of the test substance was between 0.01 and 0.1 PaS at 40°C.
A flash point was not identified up to 130°C, thus the flash point is > 130°C. Auto flammability and flammability was not measured as the test substance is solid with a low melting point about 41.1 -42.6°C. The vapor pressure has been calculated using the US EPA Epi Suite v4.0 for all components present in the UVCB substance >1%w/w. The vapour pressure is assessed to be less than 1.5E-5 Pa at 25°C. The registered substance " Stearic acid, monoester with propane-1,2-diol " does not have oxidising nor explosive properties. Furthermore, the average particle size of pellets was measured to be 4.19 ± 0.55 mm.
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.
