How do you prefer to clean yourself while /out/?

Normally I'm alone and don't bother with soap as long as water or clean snow is plentiful. Or I'm covered in swamp mud and simply have stopped giving a damn. However, traveling in a group for more than five or so days is different and I'm having trouble finding something that doesn't murder my skin/hair.
Dr. Bronner’s is fantastic for cleaning, but too harsh to use on myself no matter how much I dilute it. I haven't had much success with dry shampoos or cornstarch either. Right now I'm testing pic related, scentless baby shampoo, and various types of hippy shit.
