In order to avoid hg and all the other chemicals that are in soap (you put this on your body every day), I started using soap from the health food store. It is more expensive (@$1.00 per oz. in USA), but as with everything, you can't compare quality to just a bunch of chemical substitutes. Also, because you aren't drying out your skin with chemicals, you don't need lotions as much and a bonus for me with my MCS, you can get ones sented with only essential oils. Watch out for ingredients that say "fragrance oils" as I found out that some companies (ie. Burt's Bees) use this phrase when they use some essential oils but it also contains synthetic fragrances.
