Description of key information

All the acute toxicity key studies are read across from decanol (112-30-1). The acute oral key study in rat reports an LD50 value of >5000 mg/kg (Eurofins 2009; rel 1). The acute inhalation key study in rat exposed the animals to atmosphere generated as mist for 1 hour, with a result of  LC50 >71mg/L (Scientific Associates 1977; rel 2). The acute dermal key study in rat reports an LD50 value of >5000 mg/kg (Eurofins 2009; rel 1).

Key value for chemical safety assessment

Additional information

The acute toxicity key results are read across from decanol (CAS 112 -30 -1) based on the notion that the available acute toxicity across category is found to be low.

Justification for classification or non-classification

Based on the available information it is proposed that nonanol, branched and linear (CAS 68515 -81 -1) will not be classified for acute oral, inhalation or dermal toxicity in accordance with CLP (EC regulation 1272/2008).
