personally? I'll stick with water or jojoba oil. Here are some links to the last 4 ingredients. Go down to toxicity for each one. Even if only in minimal amounts I would not want to put anything "foreign" on my cham (or any of my other critters). As for the Aloe Vera, which is great stuff, I am sure it is so small an amount to have little effect (is a skin emollient, healer, etc.)
Water is the main ingredient (listed first) so why mess with the rest. I don't mean to bash their product, I'm not, but you asked what I thought
I know people are varied on chemical/synthetic/natural issues, but my approach is that we (any living organisms on earth) take in so many foreign substances beyond our control so why take in more when we DO have some control? Again, just my personal take
