vitamin c

Since vitamin C is a weak acid, would I be correct in assuming that any potential 'vitamin C benefits' usually associated with the unprocessed forms of coriander or papaya leaves are entirely wasted in lye soap? ... and best used as powders, oil or glycerite extracts in syndet ormulations?

Hi, I would like to make my own shower gel recipe that has specific ingredients without all of the other nasty chemicals found in stor bought soaps. I specifically want to make shower gel/liquid soap and not bar soap since I don't like the thought of bacteria/mold growing on my soap overtime...

I recently purchase luxurious goat milk soap from a farmers market and listed as an ingredient is ascorbic acid. I have never heard of vitamin c being used in cp and was wondering what value it has being added. Thank you.
