SECTION 11. TOXICOLOGICAL INFORMATION
Acute toxicity studies have been bridged from a similar formulation containing a higher percentage of the
active ingredient, triclopyr. The non-acute information pertains to the technical-grade active ingredient,
triclopyr.
Acute Oral Toxicity
male rat: LD50: 3,743 mg/kg
female rat: LD50: 4,444 mg/kg
Acute Dermal Toxicity
rabbit: LD50: > 2,000 mg/kg
Acute Inhalation Toxicity
rat: LC50: > 5.2 mg/l
Exposure time: 4 h
Determined in the form of liquid aerosol.
(actual)
rat: LC50: > 20.8 mg/l
Exposure time: 1 h
Determined in the form of liquid aerosol.
Extrapolated from the 4 hr LC50.
(actual)
Skin Irritation
No skin irritation
Eye Irritation
May cause moderate irritation with temporary corneal injury.
Sensitization
guinea pig: Non-sensitizing
Chronic Toxicity
Long-term dietary exposure to triclopyr caused liver, kidney, adrenal and
mammary gland effects when tested in rats, mice and/or dogs.
Assessment Carcinogenicity
EPA classified triclopyr as a Group D chemical (not classifiable as to human carcinogenicity) based on
what was considered only marginal responses in the mammary and adrenal glands of rodents, and the
absence of additional support from structural analogs or genotoxicity.
ACGIH
None.
NTP
None.
