    Parabens. Found in fruit… such as blueberries.

    The type of preservative will depend on the final pH of your formulation.  Some will only be effective up to pH 6.0, others up to pH 8.0 or so.  But, they may be ineffective if you do not use hurdle technology and preservative boosters.

    I am personally always skeptical of “natural” preservatives in the vein of Lucidal Liquid, Grapefruit Seed Extract and such things … they’re generally junk.

    Go with a proven preservative from a reputable preservative manufacturer such as Linatural Ultra-1 or Ultra-2 for Lincoln Fine Ingredients.

    How are you defining “natural” here? Is it a material(s) derived from a natural source or one that occurs in nature but which is a synthetic version? It could make a difference of many 10’s of currency units ($, £, €, whatever) whether you choose natural or nature identical.
