Section 11  TOXICOLOGICAL INFORMATION 
Inhalation:  Vapors or mists may cause mucous membrane and respiratory irritation, 
coughing, headache, dizziness, dullness, nausea, shortness of breath and 
vomiting. High concentrations may cause central nervous system depression, 
narcosis and unconsciousness. May cause kidney, liver and lung damage. 
Skin:  May cause irritation with redness, itching and pain. Methyl ethyl ketone may 
be absorbed through the skin causing effects similar to those listed under 
inhalation. 
Eye:  Vapors may cause irritation. Direct contact may cause irritation with 
redness, stinging and tearing of the eyes. May cause eye damage. 
Ingestion:  Swallowing may cause abdominal pain, nausea, vomiting and diarrhea. 
Aspiration during swallowing or vomiting can cause chemical pneumonia and 
lung damage. May cause kidney and liver damage. 
Chronic 
Toxicity: 
Prolonged or repeated overexposure cause dermatitis and damage to the 
kidney, liver, lungs and central nervous system. 
Toxicity Data:  Acetone:  Oral rat LD50: 5,800 mg/kg 
  Inhalation rat LC50: 50,100 mg/m3/8 hours 
Methyl Ethyl Ketone:  Oral rat LD50: 2,737 mg/kg 
  Inhalation rat LC50: 23,500 mg/m3/8 hours 
  Skin rabbit LD50: 6,480 mg/kg 
Sensitization:  None of the components are known to cause sensitization. 
Carcinogenicity: None of the components are listed as a carcinogen or suspect carcinogen by 
NTP, IARC or OSHA. 
Mutagenicity:  Acetone, methyl ethyl ketone are generally thought not to be mutagenic. 
Reproductive 
Toxicity: 
Methyl ethyl ketone has been shown to cause embryofetal toxicity and birth 
defects in laboratory animals. Acetone has been found to cause adverse 
developmental effects only when exposure levels cause other toxic effects to 
the mother. 
Medical 
Conditions 
Aggravated By 
Exposure: 
Persons with pre-existing skin, lung, kidney or liver disorders may be at 
increased risk from exposure to this product. 
Section 12  ECOLOGICAL INFORMATION
