Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Due to the viscosity of the test item the density of Alkenes, C11-C14, hydroformylation products, distn. residues,
reaction products with maleic anhydride and sodium bisulfite, sodium salts could not be determined using the pycnometer method.
Therefore the study could not be performed in compliance with the guidelines. A preliminary testing for the practicability of the density test using the pycnometer method was performed for test item 'Alkenes, C11-C14, hydroformylation products, distn. residues, reaction products with maleic anhydride and sodium bisulfite, sodium salts' (batch: Rif. 7018) on 2012-07-04 at DR.U.NoACK-LABORATORIEN, 31157 Sarstedt, Germany. For this purpose 15.21 g of the test item was weighed into a 150 mL beaker on a KERN top pan balance and was kept for 20 minutes at 30°C in a LAUDA refrigerated circulator. During that time no significant changes in consistence could be observed visually for the test item. Even after further 45 minutes at a raised temperature of 50°C no significant change was distinguished for the appearance of this test item. Therefore, due to the paste-like consistence and the chemical heterogeneous properties of the test item the determination of the density using the pycnometer method is not feasible at temperatures up to 50°C. It is concluded, that under these circumstances it is not possible to fill the pycnometer completely with test item and free of air or gas inclusions, so that even the displacement method is not suitable for this kind of test item.
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.
