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

A guideline GLP study was performed to assess the ready biodegradability of the C14/C16 hydrogenated polyalphaolefin "Pentadecane, 7-methylene mixed with 1-tetradecene, dimers and trimers, hydrogenated" using the CO2 evolution test to assess the level of degradation achieved when using a non-adapted domestic sewage sludge inoculum. Using a high shear dispersion method to bring the insoluble material in contact with the inoculum, the substance attained 104% degradation after 28 days and satisfied the 10 day validation criteria to be described as readily biodegradable. Experimental values in excess of 100% were considered due to sampling/analytical variation. As the substance is readily biodegradable, further biodegradation studies are not required.
