Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There are no reliable toxicity data for sediment-dwelling organisms relating to HMBDA. A waiver is applied for this endpoint as the substance has low solubility, low potential for adsorption to sediment and minimal exposure.
Key value for chemical safety assessment
Additional information
There are no reliable toxicity data for sediment-dwelling organisms relating to HMBDA. A waiver is applied for this endpoint as the substance has low solubility, low potential for adsorption to sediment and minimal exposure.
In accordance with REACH Regulation 1907/2006, Annex X, Column 2, studies of the effects on sediment organisms need not be conducted if exposure assessment indicates no concern for exposure to that environmental compartments. It is proposed that testing is waived as there is minimal exposure as substance is an intermediate manufactured and utilized only at one location in the EU. Additionally, the substance has low solubility, making testing difficult, and not expected to adsorb to sediment or soil as the log kow is low (0.465). Therefore no further testing is needed.
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.
