Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
The key study for acute oral toxicity reports an LD50 value of >2000mg/kg in rat (Rees, 1996; rel 1). The LC50 value for acute inhalation toxicity is reported to be >0.58mg/l (Blair 1980; rel 2). The dermal LD50 (24 hour occluded) was found to be >2000 mg/kg (Rees, 1996; rel 1).
Key value for chemical safety assessment
Additional information
The most recent and high reliability studies were selected as key information. For acute oral and dermal toxicity, high reliability supporting studies were also available which were in accordance with the key information (Cassidy & Clark, 1978; rel 2)
The recorded concentration in the key study for acute inhalation toxicity is reported to be >0.58 mg/l. The recorded concentration in the key study represents the highest possible exposure concentration and is considered for classification purposes.
Justification for classification or non-classification
Acute toxicity tests of the tested material (alcohols C7 -9 linear and branched) do not indicate any potential hazard for acute, dermal or inhalation toxicity. Tests on similar substances included in this category are also supportive of these results; which do not warrant classification for any acute toxicity endpoint under DSD or GHS criteria. The substance is therefore not classified for acute toxicity in accordance with EC regulation 1272/2008.
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.
