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.
As product: 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.
Specific Target Organ Systemic Toxicity (Single Exposure)
May cause respiratory irritation.
Route of Exposure: Inhalation
Specific Target Organ Systemic Toxicity (Repeated Exposure)
Tissue injury in the upper respiratory tract and lungs has been observed in laboratory animals after
repeated excessive exposures to MDI/polymeric MDI aerosols.
Carcinogenicity
Lung tumors have been observed in laboratory animals exposed to respirable aerosol droplets of
MDI/Polymeric MDI (6 mg/m3) for their lifetime. Tumors occurred concurrently with respiratory
irritation and lung injury. Current exposure guidelines are expected to protect against these effects
reported for MDI.
Teratogenicity
In laboratory animals, MDI/polymeric MDI did not cause birth defects; other fetal effects occurred only
at high doses which were toxic to the mother.
Reproductive toxicity
Based on information for component(s): May cause harm to breastfed babies.
