Description of key information
Additional information
Studies on the acute toxicity of decanoic acid to freshwater species of three trophic levels (fish, invertebrates and algae) are available. For the toxicity to microorganisms a read across to octanoic acid is taken into account. Long-term toxicity data for fish were also not available and therefore in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5 a read across was conducted to the structurally related sodium laurate (CAS 629-25-4).
Based on the key studies algae were the most sensitive organism to decanoic acid in acute toxicity tests, with an EC50 (72 h) of 15 mg/L (nominal, growth rate). Test with aquatic invertebrates resulted in an EC50 (48 h) of > 21 mg/L (meas. geom. mean) while an LC50 (96 h) of 18.9 mg/L (nominal) was derived for fish.
Comparing the long-term results of the three trophic levels, aquatic invertebrates are considered to be the most sensitive aquatic organisms with a NOEC (21 d) of 0.2 mg/L (nominal).
Microorganisms are not expected to be sensitive to decanoic acid. This assumption is based on the EC10 (18 h) of 912 mg/L determined for the read across substance octanoic acid in a study conducted with Pseudomonas putida as the test organism.
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.
