Welcome to the Natural Preservative Cheat Sheet. An instant downloadable table that makes it really easy to see which type of preservative will work and won't work in your formulas. This includes over 20 different preservatives available here in the USA. We make it super simple for you to see if it covers gram negative/gram positive bacteria and yeast/mold/fungi. Also included is whether its cationic, nonionic, or anionic, the ph requirements, the brand names its sold under, whether its water/oil soluble and some issues that we can run into with that specific preservative.  This is helpful if you aren't sure which to try for your formulation. We do not include advice, or any other deep diving into each preservative. We also do not include stronger preservatives that are well studied like formaldehyde donors, or parabens etc. 

Each preservative functions differently, and you will have to do your own stability testing to ensure which ever one you choose to use will work in your formula. This is strictly a downloadable pdf table that you can download and print. We developed this through much research and some of our own hands-on testing with these preservatives. This information isn't always easy to come by when trying to understand if a preservative will work in your formulas. 

Once purchase is complete you will receive an email with a downloadable link to the PDF. Please email us at hello@grasslandbeauty.com if you have trouble opening or didn't receive your download link.
