Description of key information
LC50 (17-18d) > 100 mg/kg dry soil (nominal) for Triticum aestivum, Lepidum sativum and Brassica alba based on read across (OECD 208, limit test)
Key value for chemical safety assessment
Additional information
As no valid study is available for assessing the toxicity to soil macroorganisms of Triisotridecyl benzene-1,2,4-tricarboxylate (CAS No. 72361-35-4), in accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5 Grouping of substances, a read-across to the structurally related category member 1,2,4-Benzenetricarboxylic acid, mixed decyl and octyl triesters (CAS No. 90218-76-1) was conducted. The read across is justified due to a) the structural similarity of the category members and b) similar physico-chemical properties resulting in a similar environmental fate and ecotoxicity profile. Further justification is given within the endpoint summary 6.1 and within the category justification section 13.
The study with 1,2,4-Benzenetricarboxylic acid, mixed decyl and octyl triesters (CAS No. 90218-76-1) was performed under GLP and according to OECD guideline 208 using Triticum aestivum, Lepidum sativum and Brassica alba as test organisms (Scholz, 1994). This limit test performed at a nominal concentration of 100 mg/kg dry soil was conducted in artificial soil. Effects of seedling emergence and seedling growth were determined during a test period of 17 days (B. alba) and 18 days (T. aestivum, L. sativum), respectively. No phytotoxic effects were observed in the control and the treatment for any tested species.Hence, the 17-18d-LC 50 for seedling emergence and growth are determined to be > 100 mg/kg dry soil.
Thus, based on the above mentioned results, and due to the structural similarities and a consistent ecotoxicological/environmental fate profile of the substances, as are explained with in the overall endpoint summary in IUCLID chapter 6.1, it can be concluded that no toxicity of Triisotridecyl benzene-1,2,4-tricarboxylate (CAS No. 72361-35-4) to terrestrial plants is expected.
