i've had good results with leucidal liquid, and now tinosan, in serums containing water. also eager to try aspen bark extract.
are any of you familiar with any paraben-free natural preservatives suitable for anhydrous products like scrubs? eden?
it's a topic of lively discussion on another forum, and so far it's looking like the only really effective options for anhydrous products do contain parabens.
i'm not making serums to sell, so not too worried, but very curious as to whether you know of any new or emerging alternatives to parabens...
