Routes of EntryAbsorbed through skin. Inhalation. Ingestion.
Toxicity to AnimalsAcute oral toxicity (LD50): 60 mg/kg [Mouse].
Chronic Effects on Humans May cause damage to the following organs: cardiovascular system, central nervous system (CNS).
Other Toxic Effects onHazardous in case of ingestion, of inhalation.
HumansSlightly hazardous in case of skin contact (irritant, sensitizer, permeator).
Special Remarks onNot available.
Toxicity to Animals
Special Remarks onMay cause cancer based on animal test data.
Chronic Effects on Humans
May affect genetic material (mutagenic)
Special Remarks on otherAcute Potential Health Effects:
Toxic Effects on HumansSkin: May cause skin irritation. It may be absorbed through broken skin.
Eyes: May cause eye irritation.
Inhalation: May cause respiratory tract irritation and cause sneezing, coughing, hypersensitivity and other
symptoms similar to ingestion.
Ingestion: Harmful if swallowed. It is a narcotic. It may cause nausea, stomach pain, dry mouth, and vomiting. It
may affect behavior/central nervous system, cardiovascular system, urinary system, brain, liver, blood. Other
adverse health effects may include: fast heartbeat, heart palpitations, increased blood pressure, irregular heart
beat, bruising, skin rash, fever, sweating, loss of appetite, uncontrolled movements, joint pain, nervousness,
dizziness, sleepiness, agitiation, insomnia, confusion, tremors, muscle twitching, delirium, hallucinations, sense of
well-being, convulsions possibly followed by coma.
Chronic Potential Health Effects:
Skin: Repeated or prolonged skin contact may cause hypersensitivity.
Ingestion: Repeated or prolonged ingestion may cause habituation or addiction. Prolonged or repeated ingestion
may also cause sensitization (hypersensitivity) and develop skin rashes, coughs, stuffy nose, asthma, and other
allergic reactions. Hypersensitivity may develop immediately after contact or after years of exposure. Prolonged
ingestion may also cause weight loss.
Medical conditions aggravated by exposure: severe anxiety, tension or agitation, severe depression, glaucoma,
motor tics, Tourette's Syndrome, and high blood pressure.
