Hi @Tasha – I don’t believe that an all-natural, broad-spectrum preservative exists. We either don’t use water, or we refrigerate. If your formula needs to be shelf stable, and has water in it, you need a proven broad-spectrum preservative (which will not be all-natural in the true sense of the word) along with challenge-testing on the product itself. Hope that helps:)

So, what all-natural broad-spectrum preservative do you recommend for use in DIY aqueous blends?
