Cosmetic Ingredient Review Conclusion: The Expert Panel concludes that Sodium Borate and Boric Acid, in concentrations less than or equal to 5 percent, are safe as cosmetic ingredients when used as currently recommended; however, cosmetic formulations containing free Sodium Borate or Boric Acid at this concentration should not be used on infant skin or injured skin. Note: In 2003, the CIR Expert Panel considered available new data on these ingredients and reaffirmed the above conclusion. Source: Cosmetic Ingredient Review (CIR)
Cosmetic Ingredient Review Finding(s): Safe for use in cosmetics, with qualifications Source: Cosmetic Ingredient Review (CIR)

Environmental Bioconcentration: Highly water soluble materials are unlikely to bioaccumulate to any significant degree, and borate species are all present essentially as undissociated boric acid at neutral pH(1). The octanol/water partition coefficient for boric acid has been measured as 0.175(1), indicating low bioaccumulation potential(1). Boron did not bioaccumulate in 47-day and 21-day exposure tests using oysters and sockeye salmon respectively(1). Source: Hazardous Substances Data Bank (HSDB)

Environmental Fate: TERRESTRIAL FATE: The pKa of boric acid is 9.24 at 25 °C(1), indicating that this compound will exist primarily in the undissociated form at an environmental pH range between pH 5 and pH 9, although the anion form will partially exist in alkaline soils(SRC). Adsorption of boron in soils depends on pH, organic content and types of clay and minerals in the soil(1). At acidic pH, boron exists in solutions in the form of undissociated boric acid; at alkaline pH, presence of borate ion occurs, which reaches maximum adsorption at pH 8.5-9(2). Field studies have observed boron to leach readily in soil(1); undissociated boric acid is transported in soil with little adsorption(2). Volatilization of boric acid from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.6X10-12 atm-cu m/mole(SRC), based upon its vapor pressure, 1.6X10-6 mm Hg(3), and water solubility, 5X10+4 mg/L(4). Boric acid is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure. No biotransformation processes have been reported for boron compounds, including boric acid(2). Source: Hazardous Substances Data Bank (HSDB)
Environmental Fate: AQUATIC FATE: The pKa of boric acid is 9.24 at 25 °C(1), indicating that this compound will exist primarily in the undissociated form at an environmental pH range between 5 and 9, although the anion form will partially exist in alkaline waters(SRC). Boric acid leaches readily in soils(2) which indicates adsorption to suspended solids and sediment in water will not be an important fate process(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 2.6X10-12 atm-cu m/mole(SRC), derived from its vapor pressure, 1.6X10-6 mm Hg(4), and water solubility, 5X10+4 mg/L(5). However, evaporation of seawater itself is reported to be the biggest environmental contribution of boric acid to air(2). No biotransformation processes have been reported for boron compounds, including boric acid(2). 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), boric acid, which has a vapor pressure of 1.6X10-6 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. One monitoring study found that approximately 90% of boric acid in the atmosphere is in gaseous form and 10% in particulate form(3). Vapor-phase boric 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 about 38 days(SRC), calculated from its rate constant of 4.2X10-13 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(4). Particulate-phase boric acid may be removed from the air by wet or dry deposition(SRC). Source: Hazardous Substances Data Bank (HSDB)
