Safe for anal?

This may be a dumb question, but can anyone advise if the ID Juicy Lube line is safe to use anally? As part of a Christmas gift, a friend of mine literally got me an entire small box full of them, all different flavors. I understand that they are water-based, which is all that I use, but I have never used flavored lube before and some of the ingredients make me hesitant to try them without some review.
