Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aquatic bioaccumulation
The submission substance is a quaternary substance and positively charged. It is known that ionic compounds have a low potential to cross membranes. In addition the submission substance has a low measured Log Kow of 3.01 (see IUCLID Section 4.7) and therefore a bioaccumulation potential (water & sediment) is unlikely.
Terrestrial bioaccumulation
The submission substance is a quaternary substance and positively charged. It is known that ionic compounds have a low potential to cross membranes. In addition the submission substance has a low measured Log Kow of 3.01 (see IUCLID Section 4.7) and therefore a bioaccumulation potential in soil is unlikely. From the supporting substance C22-ATQ (CAS 17301-53-0) it can be concluded that also the submission substance is rapidly biodegraded/transformed in soils. The half-lifes determined from three different soils for C22-ATQ were 23.2 to 41.4 days. This is corroborated from read across to the Quat HYEQS (supporting study). The median half-life for HYEQS in soils was determined as 6.2 days.
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.
