  • Environmental Bioconcentration: An estimated BCF of 71 was calculated for trimethylhexadecylammonium chloride(SRC), using an estimated log Kow of 3.23(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate. Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2.2X10+5(SRC), determined from a structure estimation method(2), indicates that trimethylhexadecylammonium chloride is expected to be immobile in soil(SRC). Volatilization of trimethylhexadecylammonium chloride from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.9X10-10 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Trimethylhexadecylammonium chloride is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.8X10-10 mm Hg(SRC), determined from a fragment constant method(4). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2.2X10+5(SRC), determined from an estimation method(2), indicates that trimethylhexadecylammonium 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 2.9X10-10 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 its log Kow of 3.23(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is moderate. The MITI, closed bottle, and Sturm tests revealed no degradation after 10 days, microbial growth after 17 days, and 84% degradation after 13 days, respectively(8). 10-20 ppm trimethylhexadecylammonium chloride was degraded with a half-life of 3.1 days in freshwater collected from the Ohio river 1 mile below discharge from a municipal treatment plant at 20 °C and pH 6.9(9).

  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), trimethylhexadecylammonium chloride, which has an estimated vapor pressure of 2.8X10-10 mm Hg at 25 °C(SRC), using a fragment constant estimation method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase trimethylhexadecylammonium chloride may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
