  • 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. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.; 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. Whene Source: CAMEO Chemicals

  • Health Effects: Octanoic (OA) and decanoic (DA) acids are the predominant metabolites accumulating in medium-chain acyl-CoA dehydrogenase (MCAD; E.C. 1.3.99.3) deficiency (MCADD), the most common inherited defect of fatty acid oxidation. Glycine and l-carnitine bind to these fatty acids giving rise to derivatives that also accumulate in this disorder. The clinical presentation typically occurs in early childhood but can occasionally be delayed until adulthood. The major features of the disease include hypoglycemia, vomiting, lethargy and encephalopathy after fasting, infection or other metabolic stressors.

Source: Cosmetic Ingredient Review (CIR)
  • Cosmetic Ingredient Review Finding(s): Safe for use in cosmetics, with qualifications Source: Cosmetic Ingredient Review (CIR)
  • Toxicity Summary: The existing information was reviewed by the independent Expert Panel for Fragrance Safety and supports the use of Octanoic acid as described in this fragrance ingredient safety assessment. Data show that it is not genotoxic and provide a calculated Margin of Exposure (MOE) greater than 100 for the repeated dose toxicity and reproductive toxicity endpoints. Data show that there are no safety concerns for skin sensitization under the current declared levels of use. Octanoic acid is not expected to be photoirritating/photoallergenic based on evaluation of the ultraviolet/visible (UV/Vis) spectra. The local respiratory toxicity endpoint was evaluated using the TTC for a Cramer Class I material and the exposure is below the TTC (1.4 mg/day).

  • Toxicity Summary: It has been demonstrated that octanoic (OA) and decanoic (DA) acids compromise the glycolytic pathway and citric acid cycle functioning, increase oxygen consumption in the liver and inhibit some activities of the respiratory chain complexes and creatine kinase in rat brain (A15454, A15455). These fatty acids were also shown to induce oxidative stress in the brain (A15456). Experiments suggest that OA and DA impair brain mitochondrial energy homeostasis that could underlie at least in part the neuropathology of MCADD.

  • Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for octanoic acid(SRC), using a log Kow of 3.05(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 1,100 for the free acid(SRC), determined from a log Kow of 3.05(2) and a regression-derived equation(3), indicates that undissociated octanoic acid is expected to have low mobility in soil(SRC). The pKa of octanoic acid is 4.89(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 octanoic 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). Octanoic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 3.71X10-3 mm Hg(6). In Warburg respirometer tests using an activated sludge seed, octanoic acid reached 9.8, 20.4, and 32.8% of its theoretical oxygen demand after 6, 12, and 24 hours incubation, respectively(7), suggesting that biodegradation may be an important environmental fate process in soil(SRC).

  • Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1,100 for the free acid(SRC), determined from a log Kow of 3.05(2) and a regression-derived equation(3), indicates that undissociated octanoic acid is expected to adsorb to suspended solids and sediment(SRC). A pKa of 4.89(4) indicates octanoic 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 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). In Warburg respirometer tests using an activated sludge seed, octanoic acid reached 9.8, 20.4, and 32.8% of its theoretical oxygen demand after 6, 12, and 24 hours incubation, respectively(8), suggesting that biodegradation may be an important environmental fate process in water(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), octanoic acid, which has a vapor pressure of 3.71X10-3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase octanoic acid 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 1.9 days(SRC), calculated from its rate constant of 8.3X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Octanoic acid does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).

  • Uses: Caprylic acid is found naturally in the milk of various mammals, and as a minor constituent of coconut oil and palm kernel oil. It is also an endogenously produced metabolite found in the human body. Caprylic acid is used commercially in the production of esters used in perfumery and also in the manufacture of dyes. Caprylic acid is an antimicrobial pesticide used as a food contact surface sanitizer in commercial food handling establishments on dairy equipment, food processing equipment, breweries, wineries, and beverage processing plants. It is also used as disinfectant in health care facilities, schools/colleges, animal care/veterinary facilities, industrial facilities, office buildings, recreational facilities, retail and wholesale establishments, livestock premises, restaurants, and hotels/motels. In addition, caprylic acid is used as an algaecide, bactericide, and fungicide in nurseries, greenhouses, garden centers, and interiorscapes on ornamentals. Products containing caprylic acid are formulated as soluble concentrate/liquids and ready-to-use liquids. The acid chloride of caprylic acid is used in the synthesis of perfluorooctanoic acid.
