Hazard Note: Harmful

Skin, Eye, and Respiratory Irritations
Dust irritating to nose and throat if inhaled; solid irritating to skin and eyes. At elevated temp, fumes may cause irritation of eyes, resp system, and skin.
Mildly irritating to mucous membranes
Cleanup Methods
Cover with soda ash or sodium bicarbonate. Mix and add water.
Environmental considerations: Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be contained with a flexible impermeable membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.
Environmental considerations: Water spill: If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
UN 9094
Fire Fighting Procedures
If material on fire or involved in fire: Use water in flooding quantities as fog. Solid streams of water may spread fire. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide.
Fire Potential
Slight, when exposed to heat or flame; can react with oxidizing materials.
Benzoic acid is burned in oxygen as primary thermochemical standard to calibrate oxygen bomb calorimeters used in... determination of calorific value of liquid hydrocarbon fuels. If the benzoic acid is powdered (rather than pelleted...), very rapid combustion occurs and flame front may burn through the non-metallic... seals on valve seats and the bomb may be destroyed.
GRADES: Technical, CP, USP, FCC.
Industrial grade, 97.5%; Technical grade, 99.0%; United States Pharmacopeia/Food Chemicals Codex , 99.5-100.5%. /From table/
Industrial and technical grades of benzoic acid are available in molten as well as solid forms (called flakes or chips). USP/FCC grade is available in solid form either as crystals or powder.
Exposure Standards and Regulations
Drug products containing certain active ingredients offered over-the-counter (OTC) for certain uses. A number of active ingredients have been present in OTC drug products for various uses, as described below. However, based on evidence currently available, there are inadequate data to establish general recognition of the safety and effectiveness of these ingredients for the specified uses: Benzoic acid is included in topical antifungal drug products.
Reactivities and Incompatibilities
The powder burns rapidly in oxygen.
Can react with oxidizing materials.
Other Preventative Measures
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary.
Personnel protection: Avoid breathing vapors or dusts. ... Do not handle broken packages without protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Protective Equipment and Clothing
Bureau of mines dust respirator; when melted material present, use eye protection and organic respirator for fumes.
Wear rubber gloves, a mask, coveralls, a body shield and self-contained respirator.
Personnel protection: ... Wear appropriate chemical protective gloves, boots and goggles.

Octanol/Water Partition Coefficient
log Kow = 1.87
Disposal Methods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

12.2 Persistence and degradability

AEROBIC: Benzoic acid is biodegradable under aerobic conditions by bacteria present in crude municipal wastewater at less than or equal to 200 g/cu m.

12.3 Bioaccumulative potential

Measured BCF values of <10, 14, and 21 were reported for Golden ide (Leuciscus idus melanotus)(1), trout(2), and mosquito fish (Gambusia affinis)(3), respectively. According to a classification scheme(4), this BCF range suggests the potential for bioconcentration in aquatic organisms is low(SRC). Bioconcentration factors of <10(1), 100, 138, 1800, 2800(3) and 10(4) have been reported in algae (Chorella fusca)(1), algae (Oedogonium cardiacum), mosquito larvae (Culex quinquifasciatus), daphnia (Daphnia magna) and snail (Physa), respectively(3).

12.4 Mobility in soil

Koc of benzoic acid is estimated as 15(SRC), using a log Kow of 1.87(1) and a regression-derived equation(2). An experimental log Koc of 1.50 (Koc = 31) has been reported, test details not available(3). According to a classification scheme(4), these Koc values suggest that benzoic acid is expected to have very high mobility in soil. The pKa of benzoic acid is 4.20(5), indicating that this compound will exist in anion form in the environment and anions generally do not adsorb more strongly to organic carbon and clay than their neutral counterparts(6). Freundlich adsorption constants of 0.23, 0 and 0 were reported using Ersum sandy till (pH 4.7; 0.25% OC), Tirstrup melt water sand (pH 6.1; 0.09% OC) and Djursland clayey till (pH 7.6; 0.22% OC), respectively, at 6\u00b0C. Soils were collected in North Sealand and Djursland, Jutland(7). Benzoic acid displayed negligible adsorption when using a montmorillonite (Volclay bentonite, Upton WY) clay(8).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods


The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
