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.

My family has been using Aspen Kay , we really seem to like the goat milk with oatmeal. Just wondering what you though of the Aspen Kay brand bar soap? Thanks

Hi Mary,
I seem to be having the same problem. We get a bad rash when we use Kirks or Dr Bonner’s. Have you ever heard of anyone else having this problem? Castile soaps are recommended for people with skin issues so it’s odd that I’d develop a skin issue when using one. I can use any other soap, including Dial, and have no problems.Did you ever try the Kirks with aloe?

I love your website!
Regarding Ivory – the sneaky stuff you list is fragrance. Clearly unnecessary and not ‘good stuff’ but here is my question – how bad is it? I am on a tight budget and can’t spend much. I need the fewest/safest ingredients for the cheapest price. Ivory seems to be a balance of cheap with ‘almost’ pure ingredients. The tallow part doesn’t bother me with regard to animal products. I tried Dr Bonners and Kirks and we seem to have a reaction to those both, though I am not sure why but we get rashes – similar to the poster above “Mary”. I’ve seen a few websites mention some people can’t tolerate coconut oil soap – all I know is we have rashes that come with the soap and oddly….go away wen we use Dial. My goal is to reduce our chemical exposure, it’s not imperative for us as it would be for those with skin issues, but for obvious reasons I’d rather not lather up with chemicals, or at least not very many chemicals – even though those chemical soaps seem to make the rash go away. We’ve used Ivory in the past when on sale and have no reaction to it (again, we don’t have sensitive skin…I used to just buy whatever soap was on sale, usually Dial). Any thoughts on the best balance of the fewest chemicals and the lowest price? I was thinking Ivory until I found your website, now I’m not sure but I can’t afford more than 45 cents per ounce on a bar soap.Tiff .S

I LOVE Alaffia’s Good Soap!!!!! Just took advantage of Whole Foods ! a bar on Alaffia"s Good Soap. I purchased a few varieties though and now I am left wondering what the best way to store them is. Thoughts?
