The Henry's Law constant for methylparaben is estimated as 2.2X10-9 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that methylparaben is expected to be essentially nonvolatile from water and moist soil surfaces(2). Methylparaben is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 2.4X10-4 mm Hg(SRC), determined from a fragment constant method(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of methylparaben can be estimated to be 87(SRC). According to a classification scheme(2), this estimated Koc value suggests that methylparaben is expected to have high mobility in soil. The estimated pKa of methylparaben is 8.5(3), indicating that this compound will exist partially 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(4).
