Monopropylene glycol undergoes reactions with hydroxyl radicals in water. The half life of monopropylene glycol due to this reaction, based on an OH radical concentration of 10E-17 mol/litre is 2.3 years. The overall rate constant is 0.94x10E9 litre/molecule.sec.
The calculated half life of monopropylene glycol in water is 2.3 years
with an OH radical concentration of 10-17 mol/litre (Anbar,
1967). The indirect photolysis of monopropylene glycol by
photochemically-produced hydroxy radicals is slow in water.
