Description of key information
Relative density: 0.76, 1.05, 1.06 at 20 ± 0.5°C (OECD 109)
Key value for chemical safety assessment
Additional information
Relative density studies have been conducted on different samples of the registered substance. Relative density values of 0.76, 1.05 and 1.06 at 20 ± 0.5 °C were determined for the substance in accordance with OECD Test Guideline 109 and in compliance with GLP. The results are considered to be reliable and are used as weight of evidence.
In another study which has been used as supporting study, a density value of 1.026 g/cm3 at 20°C was determined for the registered substance
TOS is a UVCB substance, hence variation in the results could be as a result of the nature and composition of the samples tested.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
