Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
In Annex X, Section 9.5.1, of Regulation (EC) No 1907/2006, it is laid down that chronic tests on sediment organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on sediment organisms. In Annex XI Section 3, it is laid down that testing in accordance with sections 8.6 and 8.7 of Annex VIII and in accordance with Annex IX and Annex X may be omitted, based on the exposure scenario(s) developed in the Chemical Safety Report (“Substance-Tailored Exposure-Driven Testing”). In accordance with Annex XI Section 3, it can be demonstrated in the risk assessment that the manufacture and the use of the substance do not pose an unacceptable risk for all environmental compartments as the risk characterization ratios (RCRs) of the chemical safety assessment are below 1 for all compartments (see Chemical Safety Report Ch. 10). In addition, If the log Koc and log Kow of the substance are below 3, a low adsorption potential is indicated. In case of TPGDA, the log Koc for the molecule is estimated to be in the range between 0.4 and 3 and thus indicates no potential for adsorption (see IUCLID Ch. 5.4.1). Based on the low log Kow and the low estimated BCF values, bioaccumulation in aquatic organisms is not to be expected (see IUCLID Ch. 5.3.1 As a consequence, a transfer to the sediment compartment is rather unlikely. Moreover, according to the hazard assessment of the substance, it is not classified as a PBT or vPvB the substance. Consequently, no test on sediment organisms is performed. The equilibrium partitioning method has been used for assessing the hazard to sediment organisms.
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.
