Finding the Best Natural Soap
I admit that I love a body wash (specifically, this one), but bar soap is a much more planet-friendly choice (it's almost always plastic-free!). Bar soap is also one of the easiest products to get right when it comes to clean, safe ingredients. Unlike other categories we investigate here--like laundry detergent or shampoo--you don’t need complex formulations to make an effective cleanser. The best non-toxic bar soap is really just just saponified oils with maybe some clay or essential oil for scent.
But because this category is so simple, we hold it to an even higher standard. Our guide goes further than most: to help you identify the the best non-toxic bar soap — the ones that really do everything right.
In this guide, you’ll see how we separate soaps into Best, Good, Okay, Bad, and Sneaky Stuff. Only the bars with the cleanest ingredients, responsible sourcing, and zero unnecessary additives make it into our “Best Stuff” category.
In terms of performance, bar soaps were much easier to review than something like deodorant; unless a soap really dries out my skin or smells offensive, I feel that it’s done its job! The main criteria for evaluating the best natural soap really comes down to the quality of the ingredients and manufacturing processes. Let's get into it.

Do you have any opinion on Kiss My Face Olive Oil Bar Soap?

I don’t know this brand, but will add to our list for a future investigation!

I’m not a big fan. They have sodium benzoate and cocamidopropyl betaine listed as ingredients.

Hi Maia,
Noticed you have some goat milk soaps on the Good Stuff list, what do you think of this Goatboy brand? They are local to my state, and seem reasonably priced. We love the unscented. Would you consider this Good Stuff?
http://www.goatboy.us/ – shows goats milk, sodium hydroxide, olive oil, palm oil, coconut oil and shear butter.
Thanks!

What are your thoughts on Tom’s of Maine bar soap? Specifically the Daily Moisture with Olive Oil and Vitamin E?
Thank you very much!Mary
When I was getting rashes in the shower long ago, I was not sure what was going on. I thought maybe the water was too hot. Then I figured out the shampoo and soap I was using were to blame.
I am still struggling trying to find a shampoo. I will find one, that I do not seem to react to, then I read if it lathers it is a chemical, so I quit using shampoos that lather. I hate shampoo bars. So I just gave up and using honey to shampoo with. I person just recently told me about Rhassoul Clay. His wife is severely sensitive, so she can not live in a house. She lives in a teak boat. I still have not tried the clay.When I found Dakota free soap , that fixed half my problem. It is made by someone who was also having multiple sensitivities. The other bar soaps she has on her site, came out fairly recently.

Looks fine to me, although no ingredients are organic.Â
