Non-Redox-Active Inorganic Compounds

BENZYLTRIMETHYLAMMONIUM CHLORIDE can react with oxidizing materials (NTP, 1992). Toxic oxides of nitrogen and hydrochloric acid fumes may form in fire (USCG, 1999). Quaternary ammonium salts often serve as catalysts in reactions. They are incompatible with many strong oxidizers and reducing agents, such as metal hydrides, alkali/active metals, and organometallics. Unlike the ammonium ion, [NH4]+, and the primary, secondary, or tertiary ammonium cations, the quaternary ammonium cations are permanently charged, independent of the pH of their solution.

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 strong 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 store this chemical under refrigerated temperatures, and protect it from moisture. (NTP, 1992)

Goggles and rubber gloves (USCG, 1999)

Wear goggles and self-contained breathing apparatus. Extinguish with dry chemical, foam or carbon dioxide. Water may be ineffective on fire.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Trimethylbenzylammonium chloride's production and use as a solvent for cellulose, a gelling inhibitor in polyester resins and as an intermediate(1) and as a phase-transfer catalyst(2) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 900(SRC), determined from a log Kow of -2.17(2) and a regression-derived equation(3), indicates that trimethylbenzylammonium chloride is expected to have low mobility in soil(SRC). Volatilization of trimethylbenzylammonium chloride from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.4X10-14 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Trimethylbenzylammonium chloride is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.2X10-7 mm Hg(SRC), determined from a fragment constant method(5). Studies on the influence of chemical structure on quaternary ammonium compound (QACs) biodegradability suggest that alkyltrimethylammonium QACs will be most rapidly degraded followed by alkyldimethylbenzylammonium and alkylpyridinium QACs, although at high concentrations it may be toxic to the microbial population(6).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 900(SRC), determined from a log Kow of -2.17(2) and a regression-derived equation(3), indicates that trimethylbenzylammonium chloride is expected to adsorb to suspended solids and sediment in water(SRC). By analogy to other alkyldimethylbenzyl quaternary ammonium compounds, trimethylbenzylammonium chloride is expected to strongly adsorb to sediment and suspended organic matter(8). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 3.4X10-14 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Trimethylbenzylammonium chloride will not volatilize from water to the atmosphere(9,SRC) because it completely dissociates. According to a classification scheme(5), a BCF of <0.2(7), and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low. If released to water, trimethylbenzylammonium chloride will completely dissociate(SRC) since it is an ionic compound. By analogy to other alkyldimethylbenzyl quaternary ammonium compounds, trimethylbenzylammonium chloride may biodegrade in aquatic systems at low concentrations(8).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), trimethylbenzylammonium chloride, which has an estimated vapor pressure of 2.2X10-7 mm Hg at 25 °C(SRC), using a fragment onstant estimation method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase trimethylbenzylammonium chloride is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 1 day(SRC), calculated from its rate constant of 1.7X10-13 cu cm/molecule-sec at 25 °C(3) determined using a structure estimation method(3). Particulate-phase trimethylbenzylammonium chloride may be removed from the air by wet and dry deposition(SRC).

The rate constant for the vapor-phase reaction of trimethylbenzylammonium chloride with photochemically-produced hydroxyl radicals has been estimated as 1.7X10-13 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 1 day at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1).

A BCF of <0.2 was measured for trimethylbenzylammonium(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low.

The Koc of trimethylbenzylammonium chloride is estimated as 900(SRC), using a log Kow of -2.17(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that trimethylbenzylammonium chloride is expected to have low mobility in soil. Quaternary ammonium compounds (QACs) are strongly adsorbed by a wide variety of materials, and alkyldimethylbenzylammonium QACs are known to adsorb strongly to sewage sludge(4).

The Henry's Law constant for trimethylbenzylammonium chloride is estimated as 3.4X10-14 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that trimethylbenzylammonium chloride is expected to be essentially nonvolatile from water surfaces(2). Trimethylbenzylammonium chloride's Henry's Law constant(1) indicates that volatilization from moist soil surfaces will not occur(SRC). Trimethylbenzylammonium chloride is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.2X10-7 mm Hg(SRC), determined from a fragment constant method(3).

NIOSH (NOES Survey 1981-1983) has statistically estimated that 3,635 workers (2,606 of these are female) are potentially exposed to trimethylbenzylammonium chloride in the US(1). Occupational exposure to trimethylbenzylammonium chloride may occur through dermal contact with this compound at workplaces where trimethylbenzylammonium chloride is produced or used(SRC).

Ingestion causes gastrointestinal disturbances. Contact with liquid irritates eyes and may irritate skin. (USCG, 1999)

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. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. 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. 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. Be prepared to transport the victim to a hospital if advised by a physician. 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. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
