Description of key information
Additional information
Members of this category are considered to be readily biodegradable on the basis of calculated data for representative substances. . The category is also expected to have low potential for bioaccumulation and adsorption to soil and sediment based on their measured log Kow range of 2.31-2.4. Structural analysis of representative substance molecules indicates that they are not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups. The physico-chemical properties of but-1 -ene, 2 -methylpropene and butane indicate that the majority of such substances will ultimately be released to the atmosphere where it is quickly photooxidised in approximately 0.5 days, 0.75 days and 6.3 days respectively.
The category members are not expected to persist in the environment because they are predicted to degrade rapidly, have a low potential for adsorption to organic matter and have a low potential for bioaccumulation.
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.
