for soap on tap (at bathroom sink) we use SUKIN (no parabens, no SLS, no chemical nasties, and made in Australia). We use a tiny amount each time.

for bar soap in shower, we use very basic goat's milk soap (no colours, no shapes, no perfumes), bought in bulk from Honey And Soap Shoppe in my city. i get 10 bars for $12.

Avado bodywash. (haven't used it yet, been happy with their sunscreens).

to wash clothes, we use either Aware Sensitive by Planet Ark, or Ecostore - whichever is on special. Only a tablespoon per wash.

to wash dishes, we use Ecostore dishwashing detergent

all of these affect our skin, so i include clothes and dish stuff too. (the amount of perfume in Omo Sensitive had our whole family itchy).

the "best" soap depends on what you need it to do.

what you personally react to. Some people react to herbs, i knew someone who reacted to lavendar in some organic lavendar soaps. Not every product, suits every person.

do you want to avoid unnecessary chemicals? do you have skin that really reacts to chemicals?
does your skin react to perfumes? have you got itchy skin? most cheap soaps contain parabens, a very cheap preservative that causes skin irritations in many people.

Moo Goo milkwash is great, but i'm no longer buying it, for cost reasons.
