Hi, I am trying to create an at home face mask that I would be able to preserve and eventually sell. One of the ingredients I would like to include is banana. I want to include the fruit itself and the peel. I wanted to know if this was possible with the use of certain preservatives or if the banana is something that would just expire to easily. I am not a chemist but I am doing test runs of this mask and it definitely works at clearing the skin I just wanted to know if this was possible. Any information would help thank you.
