Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No studies on terrestrial organisms are available for the substance.

In Annex X Section 9.4 of Regulation (EC) No 1907/2006, it is laid down that tests on terrestrial organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on terrestrial 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). 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).  In addition, the subsatce is not classified as a PBT or vPvB substance.  Consequently, no tests on soil organisms are performed. The equilibrium partitioning method has been used for assessing the hazard to soil organisms in accordance with Annex IX, Section 9.4, Column 2 of Regulation (EC) No 1907/2006.

With regard to toxicity to birds, a large mammalian dataset is available for the assessment. In addition, secondary poisoning is of no concern. Therefore, and for reasons of animal welfare, no tests on birds are performed.
