Hazardous Decomposition Products: Under fire conditions may produce gases such as hydrogen
chloride and oxides of carbon and nitrogen.
Hazardous Reactions: Hazardous polymerization will not occur.
11. TOXICOLOGICAL INFORMATION
Toxicological Data:
Data from laboratory studies conducted on a similar, but not identical, formulation:
Oral: Rat LD
50
: 1,030 mg/kg (female) (estimated based on mortalities for doses tested)
Dermal: Rabbit LD
50
: >5,000 mg/kg
Inhalation: Rat 4-hr LC
50
: >2.06 mg/L
Eye Irritation: Rabbit: Corrosive/severely irritating
Skin Irritation: Rabbit: Slightly irritating
Skin Sensitization: Not a contact sensitizer in guinea pigs following repeated skin exposure.
Subchronic (Target Organ) Effects: Repeated overexposure to phenoxy herbicides may cause effects
to liver, kidneys, blood chemistry, and gross motor function. Rare cases of peripheral nerve damage have
been reported, but extensive animal studies have failed to substantiate these observations, even at high
doses for prolonged periods.
Carcinogenicity / Chronic Health Effects: Prolonged overexposure to phenoxy herbicides can cause
liver, kidney and muscle damage. The International Agency for Research on Cancer (IARC) lists exposure
to chlorophenoxy herbicides as a class 2B carcinogen, the category for limited evidence for
carcinogenicity in humans. However, more current 2,4-D lifetime feeding studies in rats and mice did not
show carcinogenic potential. The U.S. EPA has given 2,4-D a Class D classification (not classifiable as to
human carcinogenicity).
Reproductive Toxicity: No impairment of reproductive function attributable to 2,4-D has been noted in
laboratory animal studies.
Developmental Toxicity: Studies in laboratory animals with 2,4-D have shown decreased fetal body
weights and delayed development in the offspring at doses toxic to mother animals.
Genotoxicity: There have been some positive and some negative studies, but the weight of evidence is
that 2,4-D is not mutagenic.
