Diethylene glycol monoethyl ether ( ) and diethylene glycol butylether ( ) are not specific listed RTAPs, however, are HAPs and are therefore considered to be toxic air pollutants. The deminimus level for 2-butoxyethanol ( ) is used for the deminimus levels for both glycol ethers. The proportion emitted for the specific compounds of Cryscoat 749 was taken conservatively at 10%; each, however, since the specific ingredients are dissolved in water and the cleaning machine is covered, actual emissions of these compounds to the surrounding area is likely much less.
