I am so glad the gel worked out for you; it really is amazing! If you check around on this site you will find several threads where people list their recipes, some of which include ingredients intended as preservatives. There is one thread in particular where a woman tested various preservatives in the FSG to see which ones were the most effective. The preservatives ranged from things you can easily get at a health food store (essential oils, citric acid etc.) to commercial grade preservatives. HTH:-)
