General Description
PHYSICAL DESCRIPTION: Odorless white crystals or powder with a very bitter taste. A 1% solution in water is slightly alkaline to litmus. (NTP, 1992)


The Hazard fields include special hazard alerts, air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
Air & Water Reactions
Hygroscopic. May be sensitive to prolonged exposure to air. Water soluble.
Fire Hazard
Flash point data for this chemical are not available. It is probably combustible. (NTP, 1992)
Health Hazard
SYMPTOMS: Symptoms of exposure to this compound may include vomiting, collapse, convulsions and coma. Other symptoms may include corrosion or injury to the mucous membranes. It may cause nausea, esophageal damage and necrosis, hypotension and death. It may also cause dyspnea, cyanosis, paralysis of respiratory muscles possibly leading to asphyxia, and central nervous system depression (possibly with convulsions or preceded by excitement). It has depolarizing muscle relaxant properties. It can cause irritation to the skin, eyes, mucous membranes and upper respiratory tract. Intravenous or intrauterine administration may cause hemolysis.

ACUTE/CHRONIC HAZARDS: This compound is highly toxic by ingestion. It is also harmful by inhalation or skin absorption. It is an irritant of the skin, eyes, mucous membranes, and upper respiratory tract. When heated to decomposition this chemical emits very toxic fumes of carbon monoxide, carbon dioxide, nitrogen oxides and hydrogen chloride gas. (NTP, 1992)
Reactivity Profile
BENZETHONIUM CHLORIDE is incompatible with strong oxidizing agents. Incompatible with soap and anionic detergents. Can react with nitrates. Sensitive to light. Acids cause it to precipitate from aqueous solutions of >2% concentration. Stable for two weeks at temperatures up to 140 F, (NTP, 1992).
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Response Recommendations

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
No information available.
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Non-Fire Response
SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

STORAGE PRECAUTIONS: You should protect this chemical from exposure to light. Keep the container tightly closed under an inert atmosphere, and store under refrigerated temperatures. (NTP, 1992)
Protective Clothing
MINIMUM PROTECTIVE CLOTHING: If Tyvek-type disposable protective clothing is not worn during handling of this chemical, wear disposable Tyvek-type sleeves taped to your gloves.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. Splash proof safety goggles should be worn while handling this chemical. Alternatively, a full face respirator, equipped as above, may be used to provide simultaneous eye and respiratory protection.

RECOMMENDED GLOVE MATERIALS: Permeation test results for handling the neat (undiluted) chemical. If this chemical makes direct contact with your gloves, or if a tear, puncture or hole develops, replace them at once.

Butyl rubber North B-174 0.64 mm 480 min. Latex Ackwell 0.18 mm 480 min. Neoprene Edmont 29-870 0.48 mm 480 min. Polyvinyl Edmont 34-100 0.20 mm 480 min.

Permeation Test Results of Diluted Chemical in 95% ethanol: The breakthrough times of the diluted chemical at three different concentrations are given for each glove type. If a solution of this chemical makes direct contact with your gloves, or if a tear, puncture or hole develops, replace them at once

First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.

INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and, in addition, have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. Transport the victim IMMEDIATELY to a hospital. (NTP, 1992)
