Description of key information

One reliable (Klimisch 1) short-term toxicity study for invertebrates was available for Alchisor CAL 123.  The short-term toxicity of Alchisor CAL 123 to Daphnia magna was reported by Claude & Krueger (2010) in an OECD 202 guideline and GLP compliant study.  Daphnia were exposed to toxicant in measured concentrations for 48 hours, resulting in a 48-hr LC50 of >100 mg/L.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L

Additional information

The short-term toxicity of Alchisor CAL 123, characterized as Alkenes, C11-12, hydroformylation products, distillation residues, to invertebrates has been evaluated for this dossier. One reliable (Klimisch 1) short-term toxicity study for invertebrates was available for Alchisor CAL 123. The short-term toxicity of Alchisor CAL 123 to Daphnia magna was reported by Claude & Krueger (2010) in an OECD 202 guideline and GLP compliant study. Daphnia were exposed to toxicant in measured concentrations for 48 hours, resulting in a 48-hr LC50 of >100 mg/L. This reliable study result is designated as Key for the short-term toxicity to invertebrates endpoint.
