Physical and Chemical Properties

Appearance

White or yellowish-white, amorphous powder or gelatinous pieces. Aromatic odor.

Solubility in water

very soluble

Density

0.98 g/cm3

Bactericide, fungicide.

First Aid Measures

Ingestion

Do not induce emesis - dilution: following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child). The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation.

Inhalation

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.

Skin

Remove contaminated clothing, wash exposed area with copious amounts of water. A physician should examine the area if irritation or pain persists.

Eyes

Eye exposure results in mild discomfort (0.1 Percent solution) to very serious corneal damage (1 to 10 percent solution) depending on the concentration. Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

Handling and Storage

Storage

Solutions should be stored in distinctive bottles (never in soft drink bottles) in safe place.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation

Respiratory muscle paralysis, pulmonary edema, occupational asthma, and hypoxemia have been reported.

Skin

Dermal necrosis has resulted from exposure to cetrimonium bromide in concentrations ranging from 2 to 17.5 Percent. A number of these agents have caused irritant or allergic contact dermatitis.

Ingestion

Vomiting, diarrhea and abdominal pain may occur. Ingestion of concentrated solutions may produce burns of the mouth, pharynx, and esophagus. Hemorrhagic gi tract necrosis and peritonitis have been reported.

Exposure Controls/Personal Protection

Personal Protection

Wear skin protection. If fire or intense heat prevail, wear self-contained breathing apparatus.

Respirators

Use NIOSH/MSHA approved respirator appropriate for exposure of concern.

Exposure Effects

CNS depression progressing to coma, seizures, shock, and respiratory muscle paralysis has been reported.

Poison Class

3

Fire Fighting Measures

Fire Fighting

Alcohol foam, carbon dioxide, dry chemical, water fog.

Fire Potential

Slightly flammable.

Accidental Release Measures

Small spills/leaks

Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.

Stability and Reactivity

Stability

Water solutions foam strongly when shaken.
