    I think most of us view preservation as a system, and not a drop in component. A system of hurdles, with the preservative being the star of the show, but not carrying the whole show.

    As you know it starts with the chelate, followed by the pH, followed by the glycols, followed by the preservative, followed by the packaging, followed by the testing. As, well as not adding bug food like aloe, plant extracts etc.

    Good luck. Oh…and for good measure… PE 9010 is one of the most widely used globally but is a tic weak on gram + and more than a tic weak on YMF….so you need to bolster those up, some of which can be accomplished via the hurdles.

    Aloha.

        The reason people start with PE 9010…. it is one of the few….socially acceptable preservatives that does a good job on the dreaded gram- bacteria. The other loose ends….are easy to address with a little bolstering. I can’t think of a better….more socially acceptable start point to get Gram -.
