Description of key information

Behenyl Bottoms are characterised as Alcohols, C18-22, distillation residues.  In accordance with REACH Annex X, the requirement for an avian toxicity study is waived on the basis of the absence of toxicity to mammals. In addition, the substance is unlikely to accumulate through the food chain.

Key value for chemical safety assessment

Additional information

Behenyl Bottoms are characterised as Alcohols, C18 -22, distillation residues and the requirement for long-term avian testing is waived in view of the lack of toxic effects in mammals. Evidence presented in this dossier demonstrates the low toxicity to mammals, for example, Kuhn (2009) reported LD50 in rats to be >2,000 mg/kg and in a reproduction study by Szucs (2010) a NOEL of 1,000 mg/kg/day in rats was reported. Additional evidence in the OECD SIDS report (2006) of long chain alcohols reported low toxicity in chronic and sub-chronic mammalian toxicity studies. Using these combined experimental and published evidence it is assumed that the test substance is not considered to be toxic (in PBT terms) to mammals and secondary poisoning is unlikely to occur in the environment. No avian toxicity data were available.
