The acute inhalation toxicity of Santicizer 141 towards rats was investigated in a test similar to OECD Guideline 403. Five male rats were exposed to Santicizer 141 at a concentration of 2.1 mg/l for 6 hours. The procedure is designed to provide a single inhalation exposure at an elevated temperature to a concentrated atmosphere of the vaporized test material for potential toxic effects. Signs of intoxication and mortality are observed during the observation period of 10 days. All animals survived the 6 hour exposure period; 3 of 5 test animals succumbed during 10 day observation period. It was concluded that the vapors were harmful under conditions of the test. The LC50 was calculated to be 2.1 mg/l (nominal concentration) for 6 h exposure. Based on these results and according to the EU criteria outlined in 67/548/EEC and 1272/2008/EC (CLP/EU-GHS) Santicizer 141 needs to be classified as harmful by inhalation.
