Preservative: When, Why & Which One?
Hi Everyone. :) I'm new to the site and just started making lotion and want to try a few other goodies that I've read about here. I have a few Q's about preservatives, particularly pertaining to lotions, lotion bars and scrubs.
1) As I understand it, a preservative is necessary for any product that either contains water or will be exposed to water, incl. steam from the shower. Is this the only "rule" or is it safer to use a preservative in other products as well (e.g., lotion bars)?
2) I used Phenonip in my first lotion recipe at +1%, but have seen others that suggest Gerbamen II, Germal and one or two more. Can anyone explain when you should use which one and why?
Thanks So Much!
