The Henry's Law constant for p-cymene is estimated as 0.011 atm-cu m/mole(SRC), derived from its vapor pressure, 1.5 mm Hg(1), and water solubility, 23.4 mg/L(2). This Henry's Law constant indicates that p-cymene is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 3.5 hours if adsorption is neglected(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 4.6 days if adsorption is neglected(SRC). The volatilization half-life from a model pond is about 30 days if adsorption is considered(4). p-Cymene's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). p-Cymene is expected to volatilize from dry soil surfaces based upon its vapor pressure(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of p-cymene can be estimated to be 1120(SRC). According to a classification scheme(2), this estimated Koc value suggests that p-cymene is expected to have low mobility in soil.
