An estimated pKa of 4.7(1) indicates stearic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces and moist soil is not expected to be an important fate process(2). Stearic acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 4.3X10-8 mm Hg at 25 deg C(3).

The Koc of undissociated stearic acid is estimated as 710,000(SRC), using a log Kow of 8.23(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that undissociated stearic acid is expected to be immobile in soil. The estimated pKa of stearic acid is 4.75(4), indicating that this compound will exist almost entirely in the 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). However, the adsorption of stearate, the anion of stearic acid, was determined using relatively nonpolar marine sediment sand surfaces: anoxic clastic mud from Cape Lookout Bight, NC (3.5 g/g organic carbon, clay), fine carbonate beach sand from Kahana Stream, Oahu, HI (1.3 g/g organic carbon, fine sand and silty clay), and a fine carbonate sand from Waimanalo Beach, Oahu, HI (0.17 g/g organic carbon, fine-very fein sand)(6) Stearate exhibited Kds of 210, 140 and 36, respectively; overall averaging 99% adsorption(6).
