Why does “pure” alcohol feel so strange to the touch?

1.21K views

I had to clean out some PC junk recently and I used a tupperware container filled to the brim with 99% isopropyl alcohol to get the gunk out.

I dipped my hands in to get the parts out and I noticed that the alcohol felt very weird in my hands. I don’t know quite how to describe it, but it felt very strange compared to water. Not as much resistance, and it felt very weird on my skin. Almost as if there was no friction against my skin.

What’s the cause of this? Is it surface tension? Maybe a weird chemical reaction with my skin that makes it feel that way?

I googled this and only got results about treating open wounds with alcohol.

99% alcohol really wants to form an azeotrope with water, so will actually pull water from the cells in your skin in order to dilute to a 91% concentration
