Is perfume, soap, or other products considered ritually impure (najis) if they are plant-based products grown with organic fertilizer from animal manure, and it is unknown whether these animals are permissible to eat or not? And is it permissible to use soap and deodorant containing glycerin based on the company's denial that its products contain animal derivatives, or must the details of each product be investigated?

If a plant is irrigated with impure water, its fruit is pure, because when a tree or vegetable is irrigated with impure water, the fruit and vegetable are pure. The impure water has become purified by its transformation into good nourishment that the tree fed upon. It is permissible to eat and sell the fruits. As for the question about produce, there is no need to investigate it, as the general rule for things is permissibility.
