Additional information

The endpoint "toxicity to other above-ground organisms" of 1,3,4-Thiadiazolidine-2,5-dithione, reaction products with hydrogen peroxide and tert-nonanethiol is covered by the extensive data provided in Section 5 of the Chemical Safety Report (CSR). This substance is not classified in Annex I of Directive 67/548/EEC and has no classifications relevant to the mammalian toxicity criterion (i.e. Not carcinogenic or mutagenic category 1 or 2; Not reprotoxic category 1 or 2 or 3). The substance is not classified as toxic to mammals. Thus, based on the Chemical Safety Assessment (CSA), no further investigations are triggered.
