• Tested on: Rats
• Skin Overexposure effects: Prolonged skin or eye contact may causelight temporary irritation.
• Skin Irritation: Limited Tests indicate no significant long termirritation
• Eye Irritation: Limited Tests indicate no significant long termirritation.
• Inhalation Acute: Very low vapor pressure suggests that this wouldnot be applicable.
• Inhalation Chronic: Very low vapor pressure suggests that this wouldnot be applicable
• Oral Ingestion: Oral ingestion of small amounts will cause diarrhea.Oral Ingestion of large amounts could cause systemic collapse.
• Effects of Acute Exposure: Oral - see above; Skin or eye, Limitedtests indicate no significant long term irritation
• Effects of Chronic Exposure: Oral - see above; Skin or eye, Limitedtests indicate no significant long term irritation.
• Exposure Limits: No Tests Run - Very low vapor pressure combinedwith the very low toxicity and the small surface areas of the materialwhen applied to contacts suggests that for practical purposes it wouldbe virtually impossible to reach an airborne concentration that would beinjurious. Limited testing on skin exposure indicate no significant longterm irritation or sensitization. We suggest a precautionary washing ofthe exposed areas with soap and water.
