Acute toxicity
Acute oral toxicity
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. Observations in animals include: Gastrointestinal irritation.
As product: Single dose oral LD50 has not been determined.
LD50, Rat, > 2,000 mg/kg Estimated.
Acute dermal toxicity
Prolonged skin contact is unlikely to result in absorption of harmful amounts.
As product: The dermal LD50 has not been determined.
LD50, Rabbit, > 2,000 mg/kg Estimated.
Acute inhalation toxicity
In confined or poorly ventilated areas, vapor can easily accumulate and can cause
unconsciousness and death due to displacement of oxygen. Excessive exposure may cause
irritation to upper respiratory tract (nose and throat) and lungs. May cause pulmonary edema
(fluid in the lungs.) Effects may be delayed. May cause central nervous system depression.
Symptoms of excessive exposure may be anesthetic or narcotic effects; dizziness and
drowsiness may be observed. Excessive exposure may increase sensitivity to epinephrine
and increase myocardial irritability (irregular heartbeats). Decreased lung function has been
associated with overexposure to isocyanates.
The LC50 has not been determined.,
Skin corrosion/irritation
Prolonged contact may cause moderate skin irritation with local redness.
Material may stick to skin causing irritation upon removal.
May stain skin.
Serious eye damage/eye irritation
May cause moderate eye irritation.
May cause slight temporary corneal injury.
Sensitization
Skin contact may cause an allergic skin reaction.
Animal studies have shown that skin contact with isocyanates may play a role in respiratory
sensitization.
May cause allergic respiratory reaction.
MDI concentrations below the exposure guidelines may cause allergic respiratory reactions in
individuals already sensitized.
Asthma-like symptoms may include coughing, difficult breathing and a feeling of tightness in the chest.
Occasionally, breathing difficulties may be life threatening.
