Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Occurance in Nature
4 -HBA is widely distributed in the biosphere. The substance is synthesised in plants and has been found in many plants and food. 4 -HBA was found in soils which can be attributed to decomposition products from dead plants.
Environmental fate
The substance is readily biodegradable.
The substance can be expected to have a low potential for adsorption and bioaccumulation because of its low octanol water partition coefficient (log P = 0.88 for the non ionised form).
Due to its ready biodegradation and the acid character the substance is not expected to accumulate in the biosphere and geosphere.
In case of an exposure to the environment the substance is expected to be found in the compartment water. This is due to its water solubility of 4.9 g/L and non volatile properties.
Based on these properties and the requirements of REACH no further testing is necessary.
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.
