Hello! A lot of tans claim to be vegan friendly, though it is worth double checking on this and getting it in writing from the manufacturer, as many like to make all sorts of claims on their websites without any backing whatsoever. Ask for their promise that the glycerine is 100% plant derived.
As for organic, what exactly do you mean by this? What is your own definition of organic? You'll never get a 100% organic tanning solution, it's not possible, but some do contain natural and/or organic ingredients, as well as avoiding certain chemical 'nasties.'
