Yeah I would not use it for that either... Their ingredients are aloe vera, Vitamins B1 and B3, Emollient, and water. They do not specifically list what the emollient is in the product. Which I do not like. The vitamins on their own would not really be an issue since they are water soluble. So no risk of build up and toxicity if the cham licks them. But the aloe could create a coating to your plants and anything it is sprayed on. So really the main thing I do not like is not knowing what the emollient is. Which is something that is used to trap moisture into the skin by creating a film. I know it products this can be anything from oil based to cream based. So yeah sorry that was long winded lol.
