IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.; SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.; INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital.

- Cosmetic Ingredient Review Finding(s): Safe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.org Source: Cosmetic Ingredient Review (CIR)
- Environmental Bioconcentration: An estimated BCF of 71 was calculated for benzyldimethylstearylammonium chloride(SRC), using a 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 3X10+7(SRC), determined from a structure estimation method(2), indicates that benzyldimethylstearylammonium chloride is expected to be immobile in soil(SRC). Volatilization of benzyldimethylstearylammonium chloride from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 4.2X10-11 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Benzyldimethylstearylammonium chloride is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.2X10-13 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 3X10+7(SRC), determined from an estimation method(2), indicates that benzyldimethylstearylammonium 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 4.2X10-11 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(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is moderate. Using the SCAS method and the OECD Confirmatory test, 94 and 95% benzyldimethylstearylammonium chloride was degraded, respectively(8), suggesting that biodegradability in water is likely to be important(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), benzyldimethylstearylammonium chloride, which has an estimated vapor pressure of 1.2X10-13 mm Hg at 25 °C(SRC), using a fragment constant estimation method(2), is expected to exist in the particulate phase in the ambient atmosphere. Particulate-phase benzyldimethylstearylammonium chloride may be removed from the air by wet and dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
