Potential health effects

Eye Gontact: May cause slight eye irritation. May cause pain disproportionate to the level of irritation to eye tissues. Corneal injury is unlikely. Skin Gontact: Prolonged contact may cause slight skin irritation with local redness. Repeated contact may cause skin burns. Symptoms may include pain, severe local redness, swelling, and tissue damage. Skin Absorption: Prolonged skin contact is unlikely to result in absorption of harmful amounts. Skin Sensitization: Has demonstrated the potential for contact allergy in mice. Inhalation: At room temperature, vapors are minimal due to low volatilfty. Vapor from heated material or mist may be hazardous on single exposure. Excessive exposure may cause irritation to upper respiratory tract (nose and throat) and lungs. In humans, symptoms may include: Lethargy. Symptoms of excessive exposure may be anesthetic or narcotic effects; dizziness and drowsiness may be observed. Ingestion: Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury.

Aspiration hazard

Based on physical properties, not likely to be an aspiration hazard Effects of Repeated Exposure For the component(s) tested In animals, effects have been reported on the following organs: Liver. Kidney. Respiratory tract. Birth Defects/Developmental Effects: Based on analogy. Has been toxic to the fetus in laboratory animals at doses toxic to the mother. Reproductive Effects: Based on analogy. ln laboratory animal studies, effects on reproduction have been seen only at doses that produced significant toxicity to the parent animals.
