If you want to make a preservative-less product or want to use alcohol as a preservative or want to store things in your fridge, do it. If you've read all that I've written about preservatives (like why we use preservatives and what kind of contamination can wreak havoc on your products) and read what others have written about them in great forums like the Dish or great blogs like the Soap Queen and you aren't yet convinced that preservatives are necessary and far better for your skin than the inevitable contamination that you'll see in unpreserved products, then make your products without preservatives.
I've done what I can to educate on the value of preservatives and I'm exhausted in fighting what seems to be a losing battle. If you don't want to use preservatives, then don't. But please stop asking me how to do it because I can't be a party to something I consider a dangerous practice.
I'm not sure how to end this rant...so I'll just stop writing.
