I think if you are planning to sell a lotion with a 'natural preservative' it would be in your best interest to have a lab perform a challenge test on your preservative system.

Interesting, but even the supplier has concerns

In addition, challenge testing has shown that, in cosmetic formulations, of varying degrees of complexity, Willow Bark Extract , when present in concentrations of 2.5 - 5%, contributes to the preservative efficacy of formulas even when no other synthetic chemical preservatives are used. It has proven efficacy against gram positive, gram negative bacteria, yeast, and mold.

The choice of preservatives for personal care formulations should be carefully considered. This is especially true when using natural antimicrobials and or other “mild” antimicrobials. We recommend that every formula undergo stability and microbial testing to ensure adequate preservation.

How much do you intend to use? And what will the pH of your lotion be? Do you know if there are any limitations to its use (such as pH, temperature sensitivity, reactivity, oil phase, etc.)? Does it have an odor? Or discolor products do you know? How stable is the stuff? Very interesting indeed.

It's kinda expensive, unless you are using it as an "active" as well as a preservative.

I agree, and plan to do so. Does anyone know how/where to go for something like that? How much does it cost usually? Thanks!

The amount I use will be determined after lab tests. I imagine that is the only way to find out the correct amount needed to preserve.(?)
As for your other questions, I haven't made it yet so I don't know. A question about pH though-how do you determine it? I know they sell test strip kits but I read those are pretty much useless and not accurate. Thank you!

-I meant to post this in Bath & Body, sorry!
