Description of key information
The nominal 14d-LC50 value of GF-2018 to earthworms is >5000 mg/kg dw soil. Based on a concentration of 8.2% C8-18 alkylampho(di)propionates (as aqueous substance including the presence of methanol by product) in GF 2018, the reviewer calculated that the nominal 14d-LC50 value of C8-18 alkylampho(di)propionates is >410 mg/kg dw soil. Based on a concentration of ca. 3.2 % for the solid (surfactant) content of C8-18 alkylampho(di)propionates in GF-2018, the reviewer calculated that the nominal 14d-LC50 value of the solid content of C8-18 alkylampho(di)propionates is >160 mg/kg dw soil.
Key value for chemical safety assessment
Additional information
An acute earthworm toxicity study was carried out according to OECD Guideline No. 207 (1984), ISO guideline 11268-1 (1993) and GLP principles. Earthworms were exposed to the following nominal concentrations: 0 (control), 312.5, 625.0 ,1250, 2500 and 5000 mg GF-2018/kg dw soil. The nominal 14d-LC50 value of GF-2018 to earthworms is >5000 mg/kg dw soil. Based on a concentration of 8.2% C8-18 alkylampho(di)propionates (as aqueous substance including the presence of methanol by product) in GF 2018, the reviewer calculated that the nominal 14d-LC50 value of C8-18 alkylampho(di)propionates is >410 mg/kg dw soil. Based on a concentration of ca. 3.2 % for the solid (surfactant) content of C8-18 alkylampho(di)propionates in GF-2018, the reviewer calculated that the nominal 14d-LC50 value of the solid content of C8-18 alkylampho(di)propionates is >160 mg/kg dw soil.
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.
