Fires involving this compound can be controlled with dry chemical, carbon dioxide or Halon extinguishers. (NTP, 1992)

Use water spray, powder, foam, carbon dioxide.

Fresh air, rest.

Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Give one or two glasses of water to drink.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then dampen the solid spill material with toluene, then transfer the dampened material to a suitable container. Use absorbent paper dampened with toluene to pick up any remaining material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent-wash all contaminated surfaces with toluene followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered sealable containers. Carefully collect remainder. Then store and dispose of according to local regulations.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated log Koc value of 5.5(SRC), determined from an estimated log Kow of 7.7(2,SRC) and a regression-derived equation(3), indicates that octadecylamine is expected to be immobile in soil(SRC). A pKa value of 10.65(4) indicates that the protonated form will be the dominant species in moist soil surfaces and cationic molecules generally adsorb strongly to soils(SRC). Volatilization of octadecylamine from moist soil surfaces is not expected to be an important fate process since the protonated form is expected to be the dominant species based on the pKa value(4). Volatilization of octadecylamine from dry soil surfaces is not expected(SRC) based upon the estimated vapor pressure of 4.4X10-5 mm Hg at 25 °C(5). A 32% of theoretical BOD in an activated sludge inoculum was observed over a 15-day incubation period(6), suggesting that biodegradation may be rapid in the environment(SRC).

AQUATIC FATE: Based on a classification scheme(1), an estimated log Koc value of 5.5(SRC), determined from an estimated log Kow of 7.7(2,SRC) and a regression-derived equation(3), indicates that octadecylamine is expected to adsorb to suspended solids and sediment in water(SRC). A pKa value of 10.65(4) indicates that the protonated form will be the dominant species in water and volatilization from water surfaces is not expected to be an important fate process(SRC). According to a classification scheme(5), an estimated log BCF of 5.6(3,SRC), from its estimated log Kow(2,SRC), suggests the potential for bioconcentration in aquatic organisms is very high(SRC). A 32% of theoretical BOD in an activated sludge inoculum was observed over a 15-day incubation period(6), suggesting that biodegradation may be rapid in the environment(SRC).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), octadecylamine, which has an estimated vapor pressure of 4.4X10-5 mm Hg at 25 °C(2), is expected to exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase octadecylamine 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 10 hours(SRC) from its estimated rate constant of 3.4X10-11 cu cm/molecule-sec at 25 °C(SRC), determined from a structure estimation method(3). Particulate-phase octadecylamine will be removed from the atmosphere by wet and dry depostion(SRC).

The safety of Lauramine and Stearamine has not been documented and substantiated. The CIR Expert Panel cannot conclude whether these ingredients are safe for use in cosmetic products until the appropriate safety data have been obtained and evaluated.

The available data are insufficient to support safety

The Koc of octadecylamine is estimated as approximately 3.198X10+5(SRC), using an estimated log Kow of 7.7(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that octadecylamine is expected to be immobile in soil(SRC).

The effects of non-drug-containing liposomes of different compositions and sizes on the proliferation of nine cancer-derived and one normal cultured human cell lines were determined. Stearylamine- and cardiolipin-containing liposomes were toxic (ID50) at 200 uM liposomal lipid concentrations or less ...

An estimated log BCF of 5.6 was calculated for octadecylamine(SRC), using an estimated log Kow of 7.7(1,SRC) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

The Henry's Law constant for octadecylamine is estimated as 9.4X10-4 atm-cu m/mole(SRC), using a fragment constant estimation method(1). This Henry's Law constant indicates that the neutral form of octadecylamine is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as approximately 6 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as approximately 167 hours(SRC). A pKa of 10.65(3) indicates octadecylamine will exist predominately in the protonated form at environmental pHs and therefore volatilization from water and moist soil surfaces is not expected to be an important fate process(SRC). Octadecylamine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 4.4X10-5 mm Hg at 25 °C(4).
