The GRAS report cited studies in which ingestion of sodium benzoate reduced the glycine-dependent formation of creatine, glutamine, urea, and uric acid and increased the effects of procaine, lidocaine, cocaine, tetracaine, and dibucaine. Under conditions of severely restricted fluid and salt intake, benzoates increased and prolonged the concentration of serum penicillin.

The interaction between sodium benzoate (SB) and calf thymus DNA in simulated physiological buffer (pH 7.4) using acridine orange (AO) dye as a fluorescence probe, was investigated by UV-Vis absorption, fluorescence and circular dichroism (CD) spectroscopy along with DNA melting studies and viscosity measurements. An expanded UV-Vis spectral data matrix was resolved by multivariate curve resolution-alternating least squares (MCR-ALS) approach. The equilibrium concentration profiles and the pure spectra for SB, DNA and DNA-SB complex from the high overlapping composite response were simultaneously obtained. The results indicated that SB could bind to DNA, and hydrophobic interactions and hydrogen bonds played a vital role in the binding process. Moreover, SB was able to quench the fluorescence of DNA-AO complex through a static procedure. The quenching observed was indicative of an intercalative mode of interaction between SB and DNA, which was supported by melting studies, viscosity measurements and CD analysis.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of17(SRC), determined from a structure estimation method(2), indicates that sodium benzoate is expected to have very high mobility in soil(SRC). Volatilization of sodium benzoate from moist soil surfaces is not expected to be an important fate process(SRC) given sodium benzoate is expected to immediately dissociate and form the anion of benzoic acid in an aqueous environment(3), and ions do not volatilize(SRC). Sodium benzoate is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.9X10-12 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). A variety of biodegradation screening tests have found sodium benzoate to be readily biodegradable(4,5). For example, CO2 evolution rates of 85-94% were reached after 28 days using an activated sludge inoculum(4).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 17(SRC), determined from a structure estimation method(2), indicates that sodium benzoate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(SRC) given sodium benzoate is expected to immediately dissociate and form the anion of benzoic acid in an aqueous environment(3), and ions do not volatilize(SRC). According to a classification scheme(4), an estimated BCF of 3(SRC), from an estimated log Kow of -2.27(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A variety of biodegradation screening tests have found sodium benzoate to be readily biodegradable(5,6). For example, CO2 evolution rates of 85-94% were reached after 28 days using an activated sludge inoculum(5). Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions(7).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), sodium benzoate, which has an estimated vapor pressure of 2.9X10-12 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase sodium benzoate that is adsorbed to atmospheric aerosol 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 4.3 days(SRC), calculated from its rate constant of 3.7X10-12 cu cm/molecule-sec at 25 °C(3). Particulate-phase sodium benzoate may be removed from the air by wet and dry deposition(SRC).

Sodium benzoate is added directly to human food(1). It is used as a preservative in such foods as sauces, pickles, cider, fruit juices, wine coolers, syrups and concentrates, mincemeat and other acidic pie fillings, margarine, egg powder, fish (as a brine dip component), bottled carbonated beverages, and fruit preserves, jams, and jellies(1). The popularity of diet soft drinks has led to an increased demand(1).

IDENTIFICATION AND USE: Sodium benzoate is a colorless crystalline powder. It is used as food preservative, antiseptic, medicine, in tobacco, in pharmaceutical preparations, as an intermediate for manufacture of dyes, and as a rust and mildew inhibitor. HUMAN EXPOSURE AND TOXICITY: In a study with 2045 patients of dermatological clinics, only 5 persons (approximately 0.2%) showed a positive reaction in patch tests, while 34 of 5202 patients (approximately 0.7%) with contact urticaria reacted positively. Cases of urticaria, asthma, rhinitis, or anaphylactic shock have been reported following oral, dermal, or inhalation exposure to sodium benzoate. The symptoms appear shortly after exposure and disappear within a few hours. Chromosome aberration test was carried out on sodium benzoate using human embryonic lung culture cells. Sodium benzoate produced no significant increase in the aberration frequency in the anaphase chromosomes when tested at the dosage levels 0, 2.0 ug/mL, 20 ug/mL and 200 g/mL. In human embryonic lung cells (WI-38) treated with sodium benzoate both chromosome abnormalities and mitotic indices were within normal values. Sodium benzoate was mutagenic and cytotoxic in lymphocytes, where it caused micronucleus formation and chromosome break. ANIMAL STUDIES: An acute dermal irritation/corrosion study gave no indication for skin irritating effect in rabbits. Sodium benzoate was only slightly irritating to the eye. In a 90-day study with rats dosed with 0, 1, 2, 4, or 8% sodium benzoate via diet, the mortality in the highest dose group (approx. 6290 mg/kg body weight per day) was about 50%. Other effects in this group included a reduced weight gain, increased relative weights of liver and kidneys, and pathological changes in these organs. Sodium benzoate was given in drinking water to 50 female and 50 male mice from weeks 5 on for lifespan. The average daily intake of sodium benzoate was 119.2 mg for a female and 124.0 mg for a male (approx. 5.95 - 6.2 g/kg bw/d). There was no effect on the survival of the treated mice when compared with the untreated control. There were no significant differences between the tumor distribution in sodium benzoate-treated and untreated control mice. In a developmental study rats were injected intraperitoneally with 100, 315, or 1000 mg/kg sodium benzoate on gestation days 9 to 11 or 12 to 14. Reduced fetal body weight, increased in utero deaths (by 12%), and gross anomalies were noted at the highest dose. No evidence of teratogenicity was noted in rats administered 510 mg/kg of sodium benzoate by gavage on gestation days 9 to 11. Sodium benzoate (up to 3.0 mg/plate) was tested in the Salmonella/microsome test using S. typhimurium TA 92, TA 94, TA 98, TA 100, TA 1535 and TA 1537. No significant increases in the numbers of revertant colonies were detected in any S. typhimurium strains at the maximum dose. Sodium benzoate tested negative in a cytogenetic assay (bone marrow) in rats after single or multiple oral application of doses up to 5000 mg/kg body weight. In a study with mice, there was also no indication of mutagenic activity in a host-mediated assay.

EPA has released the Interactive Chemical Safety for Sustainability (iCSS) Dashboard. The iCSS Dashboard provides an interactive tool to explore rapid, automated (or in vitro high-throughput) chemical screening data generated by the Toxicity Forecaster (ToxCast) project and the federal Toxicity Testing in the 21st century (Tox21) collaboration. /The title compound was tested by ToxCast and/or Tox21 assays/[USEPA; ICSS Dashboard Application; Available from, as of July 7, 2016: http://actor.epa.gov/dashboard/]

Using a structure estimation method based on molecular connectivity indices(1), the Koc of sodium benzoate can be estimated to be 17(SRC). According to a classification scheme(2), this estimated Koc value suggests that sodium benzoate is expected to have very high mobility in soil.

/HUMAN EXPOSURE STUDIES/ The information concerning skin reactions caused by benzoic acid or sodium benzoate in the general population is limited. In a study with 2045 patients of dermatological clinics, only 5 persons (approximately 0.2%) showed a positive reaction in patch tests, while 34 of 5202 patients (approximately 0.7%) with contact urticaria reacted positively. From these data, it can be concluded that skin reactions caused by benzoic acid or sodium benzoate in the healthy general population are rare.

/HUMAN EXPOSURE STUDIES/ In Europe amoxicillin plus clavulanic acid is the most commonly prescribed antibiotic and sodium benzoate is contained in the suspension formulation as a preservative. We studied the relevance of sodium benzoate as the culprit agent in a group of children with a history of adverse reactions to amoxicillin plus clavulanic acid suspension. A total of 89 children were enrolled over a period of 3 years (2006-2009). Single blind oral provocation tests (OPTs) with amoxicillin plus clavulanic acid, sodium benzoate and placebo were performed. 20 children with recurrent idiopathic urticaria were investigated as a control group. According to personal history: 70% of reactions were late in developing while 23% of reactions were immediate and for 5% of the cases it was not possible to define the timing. 8 children (8/89=9%) resulted positive to the provocation tests with amoxicillin plus clavulanic acid; ten children (10/89=11%) had positive results with sodium benzoate; 3% had a double positivity (i.e. excipient and active drug). The timing of reactions significantly differs between the Amoxicillin plus clavulanic acid and sodium benzoate groups (p=0.002). Sodium benzoate probably acts through a non-immunologic mechanism and care should be given to children allergic to sodium benzoate containing pharmaceutical formulations.

/SIGNS AND SYMPTOMS/ Cases of urticaria, asthma, rhinitis, or anaphylactic shock have been reported following oral, dermal, or inhalation exposure to benzoic acid and sodium benzoate. The symptoms appear shortly after exposure and disappear within a few hours, even at low doses.

/GENOTOXICITY/ Chromosome aberration test was carried out on sodium benzoate using human embryonic lung culture cells. Sodium benzoate produced no significant increase in the aberration frequency in the anaphase chromosomes when tested at the dosage levels 0, 2.0 ug/mL, 20 ug/mL and 200 g/mL.

Sodium benzoate's production and use as antimicrobial and preservative in foods, soft drinks, pharmaceuticals, tobacco and cosmetics and its use as a corrosion inhibitor and chemical intermediate(1-3) may result in its release to the environment through various waste streams(SRC).

AEROBIC: Sodium benzoate, present at 100 mg/L, reached >60% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(1). Using adapted activated sludge and 10, 20, and 50 mg/L test compound, sodium benzoate had CO2 evolution rates of 85-94% after 28 days classifying the compound as readily biodegradable(2). Sodium benzoate was readily biodegradable under aerobic conditions in several standard test systems including a Modified MIT test (84% degradation, 100 mg/L, 10 days), Modified Sturm test (80-90% degrdation, 50 mg/L, 7 days) and a Closed Bottle test (75-111% degradation, 5 mg/L, 30 days)(3). Using OECD Guideline 301B and seawater as test medium or inoculum, sodium benzoate (at 10 mg/L) had degradation of 85-97% over 28 days based on CO2 measurement(4). Sodium benzoate at 3000 mg/L was readily biodegraded in a Zahn-Wellens test using activated sludge with degradation rates of 80-100% over 2-7 days(5). Results of a 20-day BOD study found sodium benzoate to have a biooxidation rate of 78-100% after 5-20 days(6); results of an OECD 301D test found biooxidation rates of 76-85% 5-28 days(6). Sodium benzoate, used as reference material in a die-away using seawater from the Bay of Cadiz (Iberian Peninsula), degraded from an initial 20 mg/L to <1 mg/L after 12 days(7).

ANAEROBIC: Anaerobic mineralization of sodium benzoate by domestic sewage sludge varied from 50% to 96.5% (measurement of carbon dioxide and methane over 28-61 days) at initial concentrations of 50-90 mg/L(1). In a study using anaerobic sludge from sewage works receiving a mixture of domestic and industrial wastewaters, 93% mineralization of sodium benzoate was observed after 1 week of incubation (measurement of carbon dioxide and methane; initial concentration 50 mg carbon/L)(2).
