The adsorption coefficient (Koc) for dipropylene glycol methyl ether acetate was estimated using the OECD Draft Document ‘Estimation of the Adsorption Coefficient (KOC) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)’, August 1999.

The adsorption coefficient (Log Koc) for the test material, obtained by interpolation of the appropriate plot, was estimated to be 2.27 ± 0.01.

The environmental distribution and transport of dipropylene glycol methyl ether acetate (DPMA) between environmental compartments (air, water, soil, and sediments) was predicted using a Level III fugacity model. This substance has high water solubility, a very low vapor pressure, and low log Kow. The substance therefore has a low potential for adsorption to soil or sediments, and a low potential to volatilize from water or soil to the atmosphere. If released to air, the substance will react with hydroxyl radicals. If released directly to water, the most probable emission route based on physical properties and use patterns, most of the substance will remain in the water compartment and is expected to be biodegraded. If released to soil, the substance is expected to be biodegraded.
