Description of key information
A study was carried out according to OECD Guideline 208 (Terrestrial Plants Test: Seedling Emergence and Seedling Growth Test) using the structural analog Didecyldimethylammonium chloride (DDAC). 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 test item had no treatment-related effect on germination or survival at rates of up to 1280 mg AI/kg soil dw for mung bean and up to 1600 mg AI/kg soil dw for mustard and wheat, the highest rates tested for the respective species. In mustard, the most sensitive species, the EC50 for treatment-related growth inhibition was calculated to be 283 mg AI/kg soil dw. The EC50 values obtained for DDAChloride was converted to DDACarbonate via the DDA+ ion using a conversion factor of 0.86 for DDACarbonate to DDA+ and 0.902 for DDAChloride to DDA+ (DDACarbonate Biocide CAR PT8, UK 2012). The EC50 value for DDACarbonate is 296.82 mg/kg dry soil.
Key value for chemical safety assessment
- Short-term EC50 or LC50 for terrestrial plants:
- 296.82 mg/kg soil dw
Additional information
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.
