Oleic Acid

Oleic acid is an octadec-9-enoic acid in which the double bond at C-9 has Z (cis) stereochemistry. It has a role as an antioxidant, a solvent, a mouse metabolite, a plant metabolite, an Escherichia coli metabolite, an EC 3.1.1.1 (carboxylesterase) inhibitor and a Daphnia galeata metabolite. It is a conjugate acid of an oleate. It derives from a hydride of a cis-octadec-9-ene. ChEBI

  • First Aid: 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.; 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. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) shou Source: CAMEO Chemicals

  • Cosmetic Ingredient Review Finding(s): Safe for use in cosmetics, with qualifications Source: Cosmetic Ingredient Review (CIR)
  • Environmental Bioconcentration: An estimated BCF of 10 was calculated in fish for oleic acid(SRC), using a log Kow of 7.64(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(SRC). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 340,000 for the free acid(SRC), determined from a log Kow of 7.64(2) and a regression-derived equation(3), indicates that undissociated oleic acid is expected to be immobile in soil(SRC). The pKa of oleic acid is 5.02(4), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of oleic acid from moist soil is not expected to be an important fate process because the acid is in the anion form and anions do not volatilize(SRC). Oleic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.46X10-7 mm Hg(6). Biodegradation is expected to be an important fate process in soil based on half-lives of 0.2 and 0.66 days in screening tests(7,8). Source: Hazardous Substances Data Bank (HSDB)
  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 340,000 for the free acid(SRC), determined from a log Kow of 7.64(2) and a regression-derived equation(3), indicates that undissociated oleic acid is expected to adsorb to suspended solids and sediment(SRC). A pKa of 5.02(4) indicates oleic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 10(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 47 and 52 theoretical %BOD for oleic acid measured over a period of 5 days using sewage inoculum(8) and a biodegradation half-life of 0.66 days using activated sludge inocula(9) suggest that biodegradation may be an important environmental fate process in aquatic ecosystems(SRC).

  • Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), oleic acid, which has a vapor pressure of 5.46X10-7 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase oleic acid is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for cis-oleic acid and trans-oleic acid reactions in air are estimated to be 5.1 and 4.6 hours(SRC), calculated from rate constants of 7.6X10-11 and 8.3X10-11cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). Vapor-phase oleic acid is also degraded in the atmosphere by reaction with ozone(SRC); the half-life for cis-oleic acid and trans-oleic acid reactions in air are estimated to be 2.1 and 1.4 hours(SRC), respectively, calculated from rate constants of 1.3X10-16 and 2.0X10-16 cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). Particulate-phase oleic acid may be removed from the air by wet or dry deposition(SRC). Oleic acid does not contain chromophores that absorb at wavelengths >290 nm and therefore i Source: Hazardous Substances Data Bank (HSDB)
