Description of key information
Additional information
The substance Peptones Beef, was found to be an organic light brown powder. The melting and boiling points studies as well vapour pressure and auto flammability study were not conducted as it is expected for peptones to decompose before reaching these points. Based on a read across form proteines hydrolysates, the bulk density is estimated to be around 383.9 kg/m3. The surface activity study was not performed because it is not a desired property of the material. No tests were needed for flash point, flammability, explosiveness and oxidising properties based on the consideration of the structure and experience in handling and use of the substance. Based on a read across from Peptones Casein, the partition coefficient is estimated to be lower than 0.3 and the range of water solubility between 8.82 and 28.96 g/L. The dissociation constant was not determined because the tests are not intended for complex substances. No tests were needed for the viscosity as the substance is not a liquid.
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.
