yeah in my experience, the eth+DMI+polysorbate80+DMSO stays very moist throughout the night... i think that is mostly the Polysorbate 80.. so i am guessing the fact that it never dries out must help with absorption, in addition to the other absorptive actions of DMI and DMSO... its worth noting perhaps, when i mix seti with minoxidil and a bit of DMI, it takes almost twice as long to dry, but still dries a lot faster than the eth+DMI+polysorbate80+DMSO vehicle...the so i know the DMI also contributes to the vehicle staying wetter/oilier longer but probably not neary as much as the polysorbate80... so for me, the eth+DMI+polysorbate80+DMSO mix is a bedtime thing vesus a morning thing, but i guess it depends on your situation... the minoxidil+DMI+seti dries out in enough time your hair doesn't look super oily at work... i bet you could do eth+DMI+seti to get a formula that would mix the seti but still dry in a reasonable time if you are doing seti twice a day like i am but didn't want the minoxidil
