WARNING!
MAY BE HARMFUL IF SWALLOWED.
CAUSES EYE IRRITATION
MAY CAUSE SKIN AND RESPIRATORY TRACT IRRITATION
MAY CAUSE ALLERGIC SKIN REACTION.
ATTENTION!
POSSIBLE CANCER HAZARD
CONTAINS CHLORENDIC ACID WHICH MAY CAUSE CANCER BASED ON ANIMAL
DATA
Risks of cancer depends on duration and level of exposure.
OSHA Regulatory Status Not regulated.
Potential Health Effects Inhalation and skin contact are expected to be the primary routes of occupational exposure to
Chlorendic Anhydride. This material is irritating to the eyes, skin and respiratory tract.
Allergic skin reaction may occur in susceptible individuals. Chlorendic anhydride is
considered, on the basis of single exposure (acute) animal tests, to be slightly toxic after
ingestion (swallowing), practically non-toxic after inhalation and skin contact, severely
irritating to eyes and practically non-irritating to skin.
Chlorendic anhydride will slowly degrade to Chlorendic acid in the presence of water and/or
sunlight. The National Toxicology Program (NTP) has concluded that there is clear evidence
of carcinogenicity (cancer) in a feeding study of rats and mice using Chlorendic acid.
International Agency for Research on Cancer (IARC) has given chlorendic acid an overall
evaluation of 2B (possibly carcinogenic).

Section 4. First Aid Measures
Eye Contact Immediately flush with plenty of water for at least 15 minutes. Get medical attention immediately.
Skin Contact Immediately wash skin with soap and plenty of water. Remove contaminated clothing and shoes. Get
medical attention if symptoms occur. Wash clothing before reuse. Destroy contaminated shoes.
Inhalation If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention.
Ingestion If swallowed, induce vomiting as directed by medical personnel. Get medical attention. NEVER GIVE
ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.

Section 11. Toxicological Information
Toxicity to Animals Acute oral toxicity (LD50): 1138-3130 mg/kg, Slightly toxic (Rat)
Acute dermal toxicity (LD50): > 10000 < 20000 mg/kg (Rabbit), practically non-toxic.
Acute inhalation toxicity (LC50): > 203 mg/l 1-hour exposure, > 65 mg/l 4-hour exposure (Rat),
practically non-toxic.
Eye Irritation: Severely irritating (Rabbit)
Skin Irritation: Practically non-irritating 0.8/8.0 (Rabbit)
Allergic skin reaction was reported in guinea pigs after repeated skin application. Repeated
skin contact produced skin irritation, stomach lesions, diarrhea, nasal and eye discharge,
decreased activity, anorexia and dehydration in rats. Decreased body weights, decreased food
consumption and changes in heart, liver, kidney and spleen weights were reported after
repeated dietary administration to rats. Repeated inhalation of dust produced nasal and eye
irritation, salivation, hair loss, decreased body weight gain, liver and thyroid changes, lesions in
the lung and stomach and cellular changes in the respiratory tract and stomach. No birth
defects were reported in the offspring of rats given Chlorendic anhydride orally during fetal
development. No genetic changes were reported in standard tests using animals and animal
and bacterial cells. Genetic changes were reported in a standard test using human cells.
Section 12. Ecological Information
Ecotoxicology 48-hour LC50: 110.7 ppm Daphnia magna, practically non-toxic
96-hour LC50: 422.7 ppm Bluegill sunfish, practically non-toxic
96-hour LC50: 422.7 ppm Rainbow trout, practically non-toxic
