Description of key information
Additional information
Didecyldimethylammonium carbonate (DDACarbonate) is not considered bioaccumulative and not very bioaccumulative based on BCF <= 2000 L/kg. The low potential to bioaccumulate was confirmed in a study on Bluegill fish with Didecyldimethylammonium Chloride (structural analogue of DDACarbonate). In view of the chemical and structural similarities (the relevant chemical part of both, DDAC and DDACarbonate, under the conditions of this test is the common quaternary ammonium cation Didecyldimethylammonium+), it is considered that the data are adequate for DDACarbonate. The study revealed a BCF of 81 in whole body. A total of 67 % of the residue was eliminated from the whole fish body after 14 days of depuration. BCF-values in edible tissue and non-edible tissue were 38 and 140, respectively. Skin tissue showed 14C-residues 2 to 6 times higher than edible tissue portions. 71 % of DDAC was eliminated from the fish non-edible tissue after 14 days of depuration while in the same period of time 57 % of the residue disappeared from the fish edible tissue.
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.
