- Toxicity Summary: Oral LD50 value of docosanoic acid for rats is greater than 2,000 mg/kg. There are no available data for irritation and sensitization. In an oral study using the OECD combined repeated dose and reproductive/developmental toxicity test [OECD TG 422], docosanoic acid was administered to rats at doses of 0, 100, 300, 1,000 mg/kg/day for at least 42 days . No deaths occurred and also no substance related toxic effects were observed in any parameters. Therefore, the NOAEL is considered to be 1,000 mg/kg/day for both repeated dose toxicity and reproductive/developmental toxicity. The chemical was negative in both a bacterial mutation test [OECD TG 471, 472] and a chromosomal aberration test in vitro [OECD TG 473]. ... Acute toxicity values of docosanoic acid on alga (Selenastrum capricornutum), aquatic invertebrate (Daphnia magna) or fish (Oryzias latipes) are greater than its water solubility (0.016 mg/L). The NOEC in a 21-day reproduction test with Daphnia magna is also greater than its water solubility. No significant effects are observed in any tests conducted at extremely high concentrations by using dispersant under OECD test guidelines [TG201, 202, 203, 204, or 211].

- Environmental Bioconcentration: An estimated BCF of 3 was calculated in fish for docosanoic acid(SRC), using an estimated log Kow of 9.91(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 1.4X10+5(SRC), determined from a structure estimation method(2), indicates that undissociated docosanoic acid is expected to be immobile in soil(SRC). The estimated pKa of docosanoic acid is 4.7(3), 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(4). Volatilization from moist soil is not expected because the acid exists as an anion and anions do not volatilize(SRC). Docosanoic is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 7.1X10-8 mm Hg(SRC), determined from a fragment constant method(5). Biodegradation of 69% of the theoretical BOD using a modified closed bottle Blok test employing a sewage inoculum incubated 28 days(6) suggests that biodegadation 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 1.4X10+5 for the free acid(SRC), determined from a structure estimation method(2), indicates that undissociated docosanoic acid is expected to adsorb to suspended solids and sediment(SRC). An estimated pKa of 4.7(3) indicates docosanoic 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(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from an estimated log Kow of 9.91(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A half life of 1.7 days in freshwater after a 29 days(8) suggests 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), docosanoic acid, which has an estimated vapor pressure of 7.1X10-8 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase docosanoic 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 14 hours(SRC), calculated from its rate constant of 2.8X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase docosanoic acid may be removed from the air by wet or dry deposition(SRC). Docosanoic acid does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
