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.

In my previous comment, I should of said that I was using the Kirks Original Coco Castile Soap. It has been around for years.

Please women, be cautious when using the Castile soaps. My sister recommended Castile soap for stripping the oils, etc., out of my hair. It was great for this but I ended up using it when I showered as my husband liked it as well. I ended up with a horrible vaginal problem because the Castile bar was stripping all of the oils out of my vagina area, and the miserable problem lasted for months. Thinking it was a yeast infection, I kept seeing my doctor who told me I did not have this problem. I finally figure out on my own what was happening as I had experienced a similar problem years before with my then very young daughters who were bathing with a then popular liquid bath soap for kids. We used to shave off pieces of a bar of Castile Soap to put in our laundry. That is how strong it is.

This has been so helpful! I’m so disappointed about Ivory soap.

Thanks for clearing up these mysteries! What are your thoughts on Iron Lion Soap?

Don’t use the soap, just threw mine all out. Just read today that it carries ingredients that are cancer causing.

This doesn’t appear to have any of those? https://gimmethegoodstuff.com/store/acure-organics-lemongrass-argan-stem-cell-shampoo-for-all-hair-types/
And neither does this soap: https://gimmethegoodstuff.com/store/paleo-skincare-tallow-and-herb-soap-for-babies/

I am extremely frustrated looking for a nontoxic with NO tea tree, lavender, hemp or grapefruit essential oils due to medications I am taking. Are there any soaps, shampoos or conditioners like this?

I am also curious about Kirk’s Original Coco Castile soap, as it is readily available at stores like Walmart and Smith’s/Kroger. The label says, “Natural, Hypoallergenic Skin Care with No Animal By-Products or Synthetic Detergents.” The ingredients are listed as: Coconut Soap, Water, Vegetable Glycerin, Coconut Oil, and Natural Fragrance.

Yes, unfortunately Ivory contains synthetic fragrance.
