- Environmental Bioconcentration: An estimated BCF of 71 was calculated for dimethyldioctadecylammonium chloride(SRC), using a log Kow of 3.80(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low. Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1X10+10(SRC), determined from a log Kow of 3.80(2) and a regression-derived equation(3), indicates that dimethyldioctadecylammonium chloride is expected to be immobile in soil(SRC). Volatilization of dimethyldioctadecylammonium chloride from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 6.4X10-8 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Dimethyldioctadecylammonium chloride is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.6X10-17 mm Hg(SRC), determined from a fragment constant method(5). In an OECD screening test, at a 2.5 mg/l concentration, dimethyldioctadecylammonium chloride degradation reaches over 90% in 2-4 days and at 10 mg/l concentration, a Zahn-Wellen test found degradation is nearly complete in 10 days(2).

- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1X10+10(SRC), determined from a log Kow of 3.80(2) and a regression-derived equation(3), indicates that dimethyldioctadecylammonium chloride is expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 6.4X10-8 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 71(SRC), from a log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is moderate. Dimethyldioctadecylammonium chloride biodegradation in river water is found to take place in 4.9-13.8 days(7,8), and an OECD and Zahn-Wellens screening test found degradation takes place in 2-10 days(2).

- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), dimethyldioctadecylammonium chloride, which has an estimated vapor pressure of 2.6X10-17 mm Hg at 25 °C(SRC), using a fragment constant estimation method(2), is expected to exist solely in the particulate phase. Particulate-phase dimethyldioctadecylammonium chloride may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
