I'm thinking about making whipped soap. Not the bars of soap that have been whipped, but the creamy whipped soap in jars. Do you need a preservative for that? Or is it like regular soap and does not need a preservative? What if I added other things into the soap (like something watery?), would it need a preservative then? I'm asking because I want to use a preservative that does not do well above 6pH. So I'd have to buy another type of preservative.
Thanks!
