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.

I am trying to get the chemicals out of my family’s daily use. We only use kirks I add it to my laundry as well as make my own dish soap, hand soap and bathe with it. It is used in everything possible. I was under the impression that it was a safe soap, what is your opinion on this. Please help with this as much as we use it, I need to change this if it is not good.

Hand made soap made with coconut oil or castor and many other healthy oils will generate a wonderful full lather. So what you read is wrong. Using Kirk’s or Dr Bonners, they are factory produced chemical soaps. Also not 100% olive oil. Olive oil does not lather in bubbles, more so then a slimy like lather. If you want real information talk to a authentic hand made soaper. Talk to several. Never take info at the only truth by reading one thing. Read everything, then pick the real out of that. Also the ingredients must be listed in full on everything, even small time crafter’s soaps. SLS, Phthalates, Parabens, are all bad. Citric acid is not needed in soap at all, and unscented is the way to go if your unsure whether it’s really an essential oil or fragrant oil.
Oh and for the record. I have been tested for allergies and am allergic to pretty much everything. I live in a real house with real pets and real kids and real dirt, that must be cleaned. I make all of our soaps, shampoos, deodorants, cleaners etc. So I know the difference between good and bad chemicals.

No reputable soap crafter would use a fragrance oil with phthalate or ingredients such with Parabens. And no, not all fragrance oils have Phthalates. This article is riddled with misinformation and basically an advertisement.
Also, you would have to be a complate idiot to believe there is an essential oil called Cotton candy. It’s a fragrance oil, and if phthalate free it should be safe. Essential oils come from plants and natural materials, not Cotton or Cotton candy or Creamsicle. Lol. Come on people, you can’t be that naive.
Also ANY store soap is basically harmful chemicals. SLS, Parabens, Phthalates are a few ingredients they may contain.
Also Citric acid and borax are used to lower the PH. Levels of liquid soap by many soapers. The wrong amounts can do more as much harm as leaving the PH. High.
Just my professional two cents.

Real Castile Soap is 100% pure olive oil and has a 0 cleansing factor. Therefore there is no way what you were using was all natural Castile Soap. I have been making it for years and there is a zero chance it caused your problem if it was pure. Castile is also not a laundry soap, laundry soap (bars) are made with borax, which is not Castile Soap. Either what you were using is not 100% Castile Soap properly made. Or it had chemicals in it that caused your issue. Heavy lye soap (also laundry soap) will do what you described as well. The popular kids liquid soap would have been nothing more then SLS, and chemicals too.

I’m looking for a reasonable natural soap but as I was reading through the comments I saw more than one person talk about Castile in Dr Bronner’s soap causing skin irritations and I was actually considering trying that one out. What should I do? Should I still try it or try something else?

I’ve been wanting to by soap from luminance skincare. Can you check these out?

Hi Maia! I have sensitive skin and have noticed that products like Neutrogena irritate my skin immensely. What would you suggest for someone like me to use on my sensitive skin? I was looking into Tom’s of Maine but was unsure. Thanks!
