Additional information

This substance does not show any evidence of toxicity via the oral route of exposure in animals when tested in accordance with OECD Guideline 401. The rat oral LD50 is 2600 mg/kg in male rats.

This substance does not show adverse toxicity effects via the dermal route of exposure in animals when tested in accordance with OECD Guideline 402. The dermal LD50 is greater than 3160 mg/kg in male rabbits.

A structurally similar material does not show evidence of systemic toxicity, or specific organ toxicity, via the inhalation route of exposure in animals when tested in accordance with OECD Guideline 403. Read-across from EC 272 -723 -1: The inhalation LD50 is greater than 2 mg/L in male rats

Justification for classification or non-classification

In accordance to Directive 67/548/EEC and EU CLP (Regulation (EC) No. 1272/2008), classification of this substance is not required for acute toxicity.
