Given the current conditions, your capacitance to conduct an assessment of
one's potential is grounds for your induction into anyone's ohm.

Never known Dewey to impede progress.
In fact there is a virtually no resistance between thought and keyboard when
there is the possibility of a Deweyism.

Well Karen, it took quite awhile for you to succumb to my (our) level of
depravity, but welcome to the club.

I'm inclined to think Polly-Ester or another string of starlets.
I guessed Tocopheryl acetate was an ester and not as bad as glycerol, but
here it is:
Tocopheryl acetate, also known as vitamin E acetate, is a common vitamin
supplement with the molecular formula C31H52O3 (for 'á' form). It is the
ester of acetic acid and tocopherol (vitamin E). It is often used in
dermatological products such as skin creams. (wikipedia)
Carbomer, a thickening agent and polymer of acrylic acid, is probably more
hydrophilic than glycerine, but there likely isn't much of it in Purell.
Good for cosmetics, not fot PWB's.

Probably Williams since we're talking about water.

Plus, I haven't a clue what Tocopheryl Acetate is, but it sounds as if
it might have an ionic bond somewhere in the molecule (it could also be
an ester).
