Description of key information
One reliable (Klimisch 1) toxicity study for aquatic algae was available for Behenyl Bottoms. The toxicity of Behenyl Bottoms to Pseudokirchnerella subcapitata was reported by Cartee et al. (2009) in an OECD 201 guideline and GLP compliant study. Algae was exposed to the test substance in measured concentrations for 72 hours, resulting in a 72-hr EC50 of >100 mg/L, based on growth, cell density and yield. The 72-hr NOEC, based on growth rate, was >100 mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 100 mg/L
Additional information
The toxicity of Behenyl Bottoms, characterized as Alcohols, C18-22, distillation residues, to aquatic algae and bacteria has been evaluated for this dossier. One reliable (Klimisch 1) toxicity study for aquatic algae was available for Behenyl Bottoms. The toxicity of Behenyl Bottoms to Pseudokirchnerella subcapitata was reported by Cartee et al. (2009) in an OECD 201 guideline and GLP compliant study. Algae was exposed to the test substance in measured concentrations for 72 hours, resulting in a 72-hr EC50 of >100 mg/L, based on growth, cell density and yield. The 72-hr NOEC, based on growth rate, was >100 mg/L. This reliable study result is designated as Key for the toxicity to aquatic algae endpoint.
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.
