Description of key information
Additional information
TOS is a UVCB substance containing naturally-occurring extracts from tree species such as pine, spruce, birch and aspen. TOS contains varying percentages of sodium salts of fatty acids, sodium salts of rosin acids and neutrals such as alcohols, sterols and high molecular weight compounds - lignins and cellulose fibres.
Environmental fate endpoints are assessed based on the properties of the whole substance and that of the individual constituents where data are available. Where data from secondary sources only are available, these are used to support the key measured/predicted data for the constituents/blocks present in the registered substance.
Individual constituents of TOS were screened for biodegradability using BIOWIN v4.10 and/or measured data.
For the purposes of environmental exposure assessment and persistence assessment, a biodegradation rating is assigned to each constituent block on the basis of the BIOWIN scores for individual constituents. Where measured data indicates a different degradation rating should be assigned to an individual constituent/block, the conclusion from such measured data is used to overwrite the conclusion from BIOWIN estimates. As far as possible, the constituents allocated to each block had the same BIOWIN-based biodegradation rating. However, to avoid use of too many blocks, and to ensure that the range of log Kow values within individual blocks was not excessive, in some cases RB10 (readily biodegradable meeting 10 day window) and RBN (readily biodegradable, not meeting 10 day window) and also INHN (inherently biodegradable not fulfilling criteria), NB (not biodegradable) and INHY (inherently biodegradable fulfilling criteria) constituents were grouped together. Where this was necessary, the overall degradation rating for the block was assigned on a case-by-case basis, taking into account the rating for the most abundant constituent(s) and/or worst rating in the block.
Biodegradation rates in water, sediment and soil compartments are predicted within EUSES 2.1.2 using the overall biodegradation rating and log Kow for the block.
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.
