tfjim- maybe I'm not a airline soap afficionado

, but they all seem the same to me. It may be the TWA soap is the same as the Alaska soap.
Lisa, I guess my bottom line would be if I was that sensitive, I would carry my own toiletries everywhere, including my own favorite handsoap to lessen the chances of reaction.
I like kissmyface oliveoil hand soap, its really gentle and not antibacterial.
You might want to check out l'occitane products- some of their stuff is pretty gentle and they are very nice about giving away freebies for travel.
As for the washing of one's face with the hand soap, sometimes you gotta do what you gotta do, but as the olay ad says:
"a facial at 30,000 feet" - those washtowels are my favorites for travel.
