The bactericidal activity of a quaternary ammonium salt, didecyldimethylammonium chloride (DDAC), was depressed by the presence of soap, sodium laurate (NaLA): the minimum lethal concentration (MLC) of DDAC against Staphylococcus aureus was 63 and 250 ug/mL in the absence and presence of 0.01% NaLA, respectively. The neutralizing effect was studied in relation with the mode of action of DDAC. The apparent uptake of DDAC by the cell was not repressed by NaLA's presence when compared to that in its absence. The solution of NaLA showed alkaline pH, but the biocidal activity of DDAC was higher at pH 11 than at pH 7. Although the presence of NaLA had no significant effect on DDAC's action on increasing the turbidity of the cell suspension, the mixture of these reagents alone without cells exhibited some turbidity. From these findings it is deduced that NaLA can form a less active complex with DDAC by both ionic and hydrophobic interactions...

TERRESTRIAL FATE: Based on a classification scheme(1), measured Koc values ranging from 677 to 9.1X10+5 in a variety soils (most >1.0X10+4)(2,3), indicate that didecyl dimethyl ammonium chloride is expected to have low to no immobility in soil(SRC). Didecyl dimethyl ammounium chloride is a cationic surfactant(2) that will exist in cation form in the environment(SRC), and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Volatilization of didecyl dimethyl ammonium chloride from moist soil surfaces is not expected to be an important fate process because cations do not volatilze(SRC). Didecyl dimethyl ammonium chloride is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of <4.3X10-5 mm Hg at 25 °C(3). Biodegradation rates of 67% or higher in 28 days using standardized biodegradation tests(3) suggest that biodegradation is expected to be an important fate process in soil(SRC).

AQUATIC FATE: Based on a classification scheme(1), measured Koc values ranging from 677 to 9.1X10+5 in a variety soils (most >1.0X10+4)(2,3), indicate that didecyl dimethyl ammonium chloride is expected to adsorb to suspended solids and sediment(SRC). Didecyl dimethyl ammonium chloride exists in the cation form at pH values of 5 to 9(2) and, therefore, volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(4), a BCF of 81, measured in bluegill sunfish (Lepomis macrochirus)(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Results of a river die-away test having 97% degradation over 30 days(4) indicate that biodegradation may be an important environmental fate process in water(SRC). In addition, results of various biodegradation screening tests have found didecyl dimethyl ammonium chloride to be readily biodegradable (OECD Guidelines 301D, 301B) or inherently biodegradable (Zahns-Wellens test) with degradation rates of 67% or higher(3). Results of aqueous hydrolysis tests found didecyl dimethyl ammonium chloride to be hydrolytically stable with half-lives of >= 1 year at pH 4, pH 7 and pH 9 at 20 °C(3). Didecyl dimethyl ammonium chloride is reported to be photolytically stable(2), and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), didecyl dimethyl ammonium chloride, which has a vapor pressure of <4.3X10-5 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase didecyl dimethyl ammonium 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 8 hours(SRC), calculated from its rate constant of 4.6X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase didecyl dimethyl ammonium chloride may be removed from the air by wet or dry deposition(SRC). Didecyl dimethyl ammonium chloride is photolytically stable(4), and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

IDENTIFICATION AND USE: Didecyl dimethylammonium chloride is a clear yellow liquid with an ethanolic odor. It is used as an algaecide, bacteriocide, fungicide, fungistat, microbiocide, microbiostat disinfectant, viricide, tuberculocide, molluscide, sanitizer, wood preservative, deodorant, and insecticide. It has been tested for treatment of impetiginized eczema patients in combination with prednicarbate. HUMAN EXPOSURE AND TOXICITY: Nausea, headache, and sore throat are the primary systemic effects that have been reported. The primary dermal effects that have been reported are rash, burning sensation, numbness, and itching. A case report of dermatitis from detergent/disinfectant was described. A 24 year old woman, who had worked in a hospital for 2 years, presented with a 2 month history of dermatitis of the dorsum of the hands and wrists. Patch testing showed she was positive for didecyldimethylammonium chloride and bis-(aminopropyl)-laurylamine which was present in detergents/disinfectants. According to the EPA classification didecyl dimethylammonium chloride is not likely to be carcinogenic to humans. ANIMAL STUDIES: In animals it is a severe eye irritant, severe dermal irritant, but not a sensitizer. It was of moderate acute oral toxicity in rodents, with possible effects on the liver and central nervous system being seen. In rats no adverse oncogenic effects were observed, however, there were treatment-related changes in both sexes in the mesenteric lymph node (blood filled sinuses, hemosiderosis and hystiocytosis) and bile duct hyperplasia at 1500 ppm. There were no developmental effects in rats. In developmental study in rabbits an increased number of dead fetuses/litter and decreased fetal body weight at 10.0 mg/kg was observed. In the Ames test, with or without the microsomal activation (S-9 fraction), didecyl dimethylammonium chloride was not mutagenic to Salmonella typhimurium tester strains. It was not mutagenic in vivo in rats, in Chinese hamster ovary cells, and did not produce unscheduled DNA synthesis. ECOTOXICITY STUDIES: Swimming performance decreased significantly in juvenile rainbow trout. Significant decreases in larval growth and survival were noted at all tested concentrations and in all sturgeon age groups. The larval stage was usually more sensitive than the fry stage. Acute toxicity tests with fertilized eggs were unsuccessful. Developmental stage altered the sensitivity of coho salmon to Bardac 2280, with alevins being approximately twice as sensitive as smolts.

/AQUATIC SPECIES/ The acute lethal and sublethal toxicity of didecyldimethylammonium chloride (DDAC) to juvenile rainbow trout (Oncorhynchus mykiss) was investigated. The nominal 96-hr LC50 value in a flow-through exposure system was 0.409 mg/L. Investigation of the effects of acute sublethal exposures on blood chemistry, swimming performance, disease resistance, and gill morphology revealed no adverse effects after a 24-hr exposure to 0.1 mg DDAC/L. Primary and secondary biochemical indicators of stress, i.e., plasma cortisol, glucose, and lactate levels, were only significantly elevated after a 24-hr exposure to DDAC at 0.4 mg/L. However, swimming performance decreased significantly after 12- and 24-hr exposures to both 0.2 and 0.4 mg/L. Scanning electron microscopic analysis revealed no gross disruptions to gill epithelial surfaces as a result of toxicant exposure. A disease challenge test revealed that exposure to sublethal concentrations of DDAC for 24 hr had no significant effect.

/AQUATIC SPECIES/ This study was conducted to describe the acute lethality and latent toxicity of didecyldimethylammonium chloride (DDAC) on early life stages of white sturgeon (Acipenser transmontanus). Fish responses to 0, 10, 50, 100, 250, 500 ug/L concentrations of DDAC were determined using a 96-hr standard static renewal method for acute toxicity testing, with three replicates per concentration. Twenty fish per replicate were tested for 3, 11, and 42-day-old larvae, and 7 fish per replicate were tested for 78-day-old juveniles. Following exposure, survival and growth were evaluated in exposed fish raised in clean water for 2 weeks. The 96-hr median lethal concentration (LC50) values for DDAC were 10.0 to 50.0, 58.5, and 99.7 ug/L for 3, 11, and 42-day-old larvae and 100 to 250 ug/L for 78-day-old juveniles. Significant decreases in larval growth and survival were noted at all tested concentrations and in all sturgeon age groups. Results of this study reveal age- and concentration-dependent responses to DDAC. Among the age groups tested, the 3-day-old larvae were the most sensitive group. Results also revealed that 96-hr lethality testing alone is not adequate for determining the toxicity of DDAC to white sturgeon.

/AQUATIC SPECIES/ The primary goal of this study was to investigate the possibility of using early life stages of white sturgeon (Acipenser transmontanus) (eggs, larvae and fly) as a species relevant to the Fraser River, B.C., for the acute and sublethal toxicological testing of forest industry effluents. Here reported the first successful acute toxicity tests for 8-day-old larvae and 42-day-old fry exposed to several chemicals known to be released into the Fraser River (i.e., 6 monochlorovanillin (6 MVAN), 4,5 dichloroguaiacol (4,5 DCG), 4,5 dichlorocatechol (4,5 DCAT), pentachlorophenol (PCP), and didecyldimethylammonium chloride (DDAC)). In most cases, white sturgeon fry were at the lower end of the range for acute toxicity values for chlorinated phenolic compounds, when compared with other juvenile fish species, and they were extremely sensitive to DDAC. The larval stage was usually more sensitive than the fry stage. Acute toxicity tests with fertilized eggs were unsuccessful.

EPA has released the first beta version (version 0.5) of the Interactive Chemical Safety for Sustainability (iCSS) Dashboard. The beta version of 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; Click on the "Chemical Explorer" button on the tool bar to see the data./[USEPA; ICSS Dashboard Application; Available from, as of November 4, 2014: http://actor.epa.gov/dashboard/]

Levels of didecyl dimethyl ammonium chloride from treated packages of lumber following rainfall events were reported as 73.2 and 65.8 mg/L after 2 events, averaging 15.9 mg/L over 15 events(1). The discharge measured into the Fraser River (British Columbia, Canada)was 1.06 mg/L(1).

The log Koc for didecyl dimethyl ammonium chloride has been reported as 5.64 (sand), 5.96 (sandy loam), 6.20 (silty clay loam), 6.17 (silt loam)(1), corresponding to Koc values of 4.4X10+5, 9.1X10+5, 1.6X10+6, and 1.5X10+6 respectively(SRC). In batch equilibrium studies using five different soil types and OECD Guideline 106 (Adsorption - Desorption Using a Batch Equilibrium Method), didecyl dimethyl ammonium chloride had Koc values of 667, 1140, 10456, 14072 and 24433(2). According to a classification scheme(2), these Koc values suggest that didecyl dimethyl ammonium chloride is expected to have low to no mobility in soil with most Koc values suggesting the compound is immobile in soil. Didecyl dimethyl ammounium chloride is a cationic surfactant(1) that may exist in cation form in the environment(SRC), and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Didecyl dimethyl ammounium chloride binds rapidly to suspended solids and sediments(1). Reported Kd values at 25 °C are 3.03 (sand), 3.91 (sandy loam), 4.52 (silty clay loam), and 4.49 (silt loam)(1).

/SIGNS AND SYMPTOMS/ There are 1,105 incidences that have been reported in the California Pesticide Surveillance Program Database (1982-2003) as definitely, probably, or possibly related to quats. ...Nausea, headache, and sore throat are the primary systemic effects that have been reported. The primary dermal effects that have been reported are rash, burning sensation, numbness, and itching. ...Although there are some people who were unable to work after exposure for a certain period of time, no one was hospitalized. /Quaternary ammonium compounds/

/SIGNS AND SYMPTOMS/ There have been nearly 2700 incidents reported to the OPP Incident Data System (IDS) and the California Department of Pesticide Regulation (1982-2004) associated with exposure to end-use products containing quaternary ammonium compounds (Quats). Most of the incidents are related to dermal, ocular and inhalation irritation. Allergic type reaction /has/ also been reported in some incidents. ...Inhalation incident symptoms: respiratory irritation/burning, irritation to mouth/throat/nose, coughing/choking, chest pain, disorientation, dizziness, shortness of breath. Dermal incident symptoms: irritation/burning, rash, itching, and blistering. Allergic symptoms: hives and allergic contact dermatitis. Oral incident symptoms: irritation to mouth/throat/nose, vomiting/nausea/abdominal pain, dizziness, and headache. Ocular incident symptoms: irritation/burning, eye pain, conjunctivitis, swelling eye and swelling of eyelid. /Quaternary ammonium compounds/

/CASE REPORTS/ A case report of dermatitis from detergent/disinfectant was described. A 24 year old woman, who had worked in a hospital for 2 years, presented with a 2 month history of dermatitis of the dorsum of the hands and wrists. The cause of her dermatitis was linked to the use of a particular detergent/disinfectant at work. Seven months later after she had changed jobs to a work location where she had no obvious contact with detergents or disinfectants she presented again with dermatitis. This time she had involvement of the eyelids, face, and arms. Her office had been cleaned with a different detergent the day before. Each time the room was cleaned she had to wait until the floor dried or she would get a new episode of dermatitis. Symptoms were so severe that the patient required systemic treatment with corticosteroids. Patch testing showed she was positive for didecyldimethylammonium chloride (DC, Bardac 22) and bis-(aminopropyl)-laurylamine which was present in both detergents/disinfectants. DC is also used on wood to protect it from termites and as a fungicide and as an algicide in swimming pools. The /study concludes/ that dermatitis caused by exposure to quaternary ammonium compounds may occur in other susceptible individuals.

/OTHER TOXICITY INFORMATION/ Cancer Classification: Not Likely to be Carcinogenic to Humans

/OTHER TOXICITY INFORMATION/ The relative toxicity of Aliquat 203 (didecyl-dimethyl-ammonium-chloride) was experimentally investigated in mice, rats, guinea-pigs, rabbits, and humans. These studies produced no evidence of an unusual degree or kind of toxicity. No data were found which indicated potential toxicologic hazard from wearing of uniforms impregnated with 0.5 percent Aliquat 203. An infrared spectrum of the technical-grade compound was evaluated also.

Didecyl dimethyl ammonium chloride's production and use as a disinfectant and microbiocide in various applications(1,2) may result in its release to the environment through various waste streams; its use as a general purpose disinfectant and pesticide, in water treatment of cooling towers and as a wood preservative(1,2) will result in its direct release to the environment(SRC).

AEROBIC: Didecyl dimethyl ammonium chloride biodegradation test results(1).[Table#7301]

AEROBIC: Didecyl dimethyl ammonium chloride, present at 5.51 mg/L, reached 72% degradation in 28 days using an activated sludge inoculum acclimated for 25 days in the Closed Bottle test(1). The compound was 96% biodegraded when 5 ppm was incubated for 42 days in synthetic sewage in the OECD Confirmatory test(2). Submitting didecyl dimethyl ammonium chloride at a concentration of 20 ppm to biodegradation using activated sludge in the OCED Coupled Units test resulted in 0-38% biodegradation as DOC in three days(3). OECD Confirmatory testing showed a 94.8% removal, with 23-29% being lost in the sterile control through 21 days of operation(4). Using a continuous flow activated sludge (OECD Confirmatory Test) with acclimated sludge, 95% removal was observed at a test chemical concentration of 5 ppm; a 15 ppm test chemical concentration resulted in 0.3% DOC removal(5). Results of a river die-away test were 97% degradation over 30 days using water from the Guadalquivar River, Seville, Spain and a test chemical concentration of 5 ppm(2).

AEROBIC: Quarternary ammonium compounds have been shown to biodegrade, exhibiting lag times of less than one to several days at a concentration of 5 mg/L(1). The half-life of analogous 12 carbon alkyl chain didodecyl dimethyl ammonium chloride has been reported at 21 days(1).

Residues of the following chemical substances are exempted from the requirement of a tolerance when used in accordance with good manufacturing practice as ingredients in an antimicrobial pesticide formulation, provided that the substance is applied on a semi-permanent or permanent food-contact surface (other than being applied on food packaging) with adequate draining before contact with food. ... (c) The following chemical substances when used as ingredients in an antimicrobial pesticide formulation may be applied to: Food-processing equipment and utensils. 1-Decanaminium, N-decyl-N,N-dimethyl-, chloride is included on this list. Limit: When ready for use, the end-use concentration is not to exceed 200 ppm of active quaternary compound.

The Agency has completed its assessment of the dietary, residential, occupational, drinking water, and ecological risks associated with the use of pesticide products containing the active ingredient DDAC. Based on a review of these data and on public comments on the Agency's assessments for the active ingredient DDAC, the Agency has sufficient information on the human health and ecological effects of DDAC to make decisions as part of the tolerance reassessment process under FFDCA and reregistration process under FIFRA, as amended by FQPA. The Agency has determined that DDAC-containing products are eligible for reregistration provided that: (i) current data gaps and confirmatory data needs are addressed; the risk mitigation measures outlined in this document are adopted; and (iii) label amendments are made to reflect these measures. ... Based on its evaluation of DDAC, the Agency has determined that DDAC products, unless labeled and used as specified in this document, would present risks inconsistent with FIFRA. Accordingly, should a registrant fail to implement the risk mitigation measure identifie in this document, the Agency may take regulatory action to address the risk concerns from the use of DDAC. If all changes outlined in this document are incorporated into the product labels, then all current risks for DDAC will be substantially mitigated for the purposes of this determination. Once an Endangered Species assessment is completed, further changes to these registrations may be necessary as explained in Section III of this document.

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer saftey standards, such as those described in the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA '88 were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern than those on List C, and with List C containing pesticides of greater concern than those on List D. Didecyl dimethyl ammonium chloride is found on List C. Case No: 3003; Pesticide type: fungicide, herbicide, antimicrobial; Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the RED document.; Active ingredient (AI): didecyl dimethyl ammonium chloride; Data Call-in (DCI) Date(s): 10/13/95; AI Status: The producers of the pesticide have made commitments to conduct the studies and pay the fees required for reregistration, and are meeting those commitments in a timely manner.
