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).
