    That depends.  How damp is the skin? (How much water is present)?  How soaked was the cotton ball with propanediol?

    I’d guess anywhere from 1:1  to 1:100  (water:propanediol)

    I think the correct answer is:  2.47359 parts Water / 97.52641 Propanediol

    I was inspired to ask this question after having seen a bottle of glycerin at the store that said to put some on a cotton ball and wipe across a moist face. Now I would think the ratio of glycerin to water would be much too high, thus it would be very sticky. But I wasn’t sure. Maybe it’s already diluted even though there wasn’t any other ingredients labeled.
