Some of those are toxic to fish and insects. The soap will still mess up the ecosystem in the lake if it doesn't have a good flow of water in and out of the lake. Jojoba oil is roughly 12% Eugenol, which is used to euthanize fish (other cheaper Eugenol oils are typically used though). Peppermint Oil is a pesticide (specifically the Menthol). Those were the only 2 I looked up, I suspect several of the others would imbalance the ecosystem too. Just because a product contains only natural ingredients that are safe for humans, doesn't mean its safe for use in small bodies of water.
