Description of key information
Tin disulfide is an inorganic, solid chemical. Hence, abiotic and biotic degradation investigations for the substance are not required according to REACH (EC 1907/2006). Furthermore, tin disulfide is insoluble in water (< 1 µg/L). Hence bioaccumulation and transport of the substance across water and soil/sediment compartments of the environment is not expected. The substance is used as fine texture powder: Average 90% (D90) of solid substance particles is < 6.22 µm, i.e., the texture of clay; average 10% (D10) is < 0.59 µm, i.e., colloidal. Hence any particulate material which may enter STPs will be retained by sedimentation and/or flocculation. Hence, contamination of surface water is excluded. Any particulates of the substance which might reach soil/sediment (directly or indirectly) will be filtered during passage through soil/sediment. Hence contamination of surface and groundwater is excluded.
Based on its physical-chemical properties and the a.m. behaviour of solid particles, the substance does not pose a hazard to the environment: Further exposure and risk assessments for surface water, sediment, soil, and groundwater compartments of the environment are not required, according to Annex IX of REACH.
Furthermore, the substance occurs naturally as the mineral „Berndtite“ (seehttps://www.mindat.org/min-637.html). Hence, a quantitative environmental risk assessment is not possible since it cannot be distinguished between effects (if any) caused by the substance entering the environment by human use and effects (if any) of the naturally occurring substance.
Additional information
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.
