Using Fruits/Veggies in Soap--Preservative Questions
by Elizabeth

I really want to make some soap using fruits and vegetables and I'm thinking that means I need to use a preservative of some sort (right?).
I keep reading contradictory statements about preservatives (which ones to use, if they're necessary at all, etc).
Are LiquaPar Optima, Optiphen, and Phenonip for use in bar soaps or just lotion/liquid soap products?
If you could shed any light on these questions I'd greatly appreciate it--thanks for your time!
Answer:Many preservatives are for water based lotion type products and cannot be used in handmade soaps. This is due to the high temperatures during in the process and the alkaline nature of soap.
Optiphen, Phenonip and LiquaPar Optima are not for use in preserving handmade soaps.
If you want to use fruits and vegetables in your soaps, you will have to blend them into a watery puree and add them in place of the water.
I have made soap using finely ground orange/lemon rinds and dehydrated carrot peelings that have been finely ground and had no problem with spoilage. These were all added as a powder at a thin trace.
I've never made soap using the puree method so I'm unable to advise you on that....sorry. From what I understand, it's fine as long as you do not use chunks of fruit/veggies. I'm not sure what the shelf life is like though.
Good luck,
