Description of key information
Liithium salicylate is expected to be readily biodegradable in aerobic freshwater systems, based on read-across to dilithium salicylate, which degraded to 89% in the standard OECD 301F testing guidelines. This substance is not expected to persist in the environment under aerobic conditions. Dilithium salicylate biodegraded to 65% at 4 days and reached 89.4% in the OECD 301F ready biodegradability test after 28 days.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of Lithium Salicylate was determined by read-across to Dilithium Salicylate. This read-across approach is based on the hypothesis that the hydrolysis of the dilithium salt of salicylic acid where the carboxylic acid and hydroxyl group are present in the meta-isomer position would show similar biodegradation and toxicity patterns to the monolithium salt. The fate of the target substance (monolithium salt) is predicted based on complete dissociation into salicylic acid and lithium hydroxide with the source substance liberating two lithium ions.
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.
