Description of key information
Additional information
If Atmer 163 (CAS No. 97925-95-6) is released into water an evaporation from water into air is negligible due to the calculated Henry’s Law constant (0.000261 – 0.000461 Pa m³/mole). Due to the rapid half-life in air calculated according to SRC AOPWIN to be 2.988 – 3.198 h, it is concluded that the substance will not accumulate in air and will not be transported through the vapour phase into other environmental compartments in relevant amounts. Thus, air is not a likely route of environmental contamination and no accumulation and subsequent deposition of the substance is to be expected. Based on the physico-chemical properties such as low water solubility and moderate adsorption potential (log Koc of 2.46 – 3.01), sediment and soil are expected to be the main targets for environmental distribution. This assumption is in line with Level I Mackay distribution modelling of Atmer 163 in the environment (45.8% will participate to the soil and 46.3% to the sediment).
The estimated Henry's Law constant, phototransformation in air and adsorption coefficient varies between the test material components since the substance is a multi-constituent.
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.
