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.

Maia I did not know where to post this on your page since it’s regarding hand soaps, but I noticed Better Life hand soap has PEG in the ingredient list. I was shocked, and deflated! I’ve always trusted their entire brand and never noticed nasty ingredients in their dish soap or cleaning sprays. Has anyone else noticed this?

Very informative website! We
used Miracle 11 soap for twenty years buying two gallons at a which usually lasted several years for bath, shower, shampoo. This last gallon has changed from its green (coloring has been the one questionable item in their recipe). we recently hanged to pascalite bar soap and do like it as well as other skin care products. But open to economical gallon size products. Thought EO Products was the new line for us but they seemed not to list a lot of organics as they last year when was scouting around for new options.

I am sorry to say Castelbel contains fragrance not reco’d by EWG they lie about the ingredients and production methods. I was given their “goat’s milk triple -milled french lavender fragranced” soap — no goat’s milk (obviously no real lavender with the use of “fragranced”). Using it to freshen the basement.

First, I’d like to thank you for all the research you’ve done on our behalf!
My question is regarding, ‘Makes 3 Organics’ soap. What are your thoughts in this brand? Thank you!Simplà Soaper
Thank you, A REAL ARTISAN SOAP CRAFTER. I am also a professional soaper and the term “fragrance” is not necessarily a bad thing and depends upon the supplier. MOST soap-safe fragrance oils are now phthalate free—particularly from legit vendors. Generally speaking, handmade (from scratch), artisan soaps do not contain SLS, parabens, synthetic detergents and foaming agents, etc and should have clearly marked ingredients…important for those with allergy/sensitivities, also. Additionally, a reputable soaper will typically disclose on their website and marketing materials that their ingredients are responsibly sourced, phthalate- and paraben-free, organic (when applicable), Non GMO….if that is part of their branding.

Update on Nature’s Plus Beauty Bar, the ingredients list customer service gave me is far longer, but still looks relatively ok from my point of view, here it is:
tapioca starch, vegetable glycerin and oils (olive and sunflower), potassium sulfate (EWG score 1), water, bentonite (EWG score 2), betaine (EWG score 1), essential oil (lemon), iron oxide (EWG score 2, used as colorant), non milk lactic acid, citric acid, allantoin, vitamin E, phosphate (no EWG score).

Hi Maia, I absolutely love your page. I’m curious what your thoughts are on Dr. Woods soap? http://www.drwoods.com/product/bar-soap-lavender/
Appreciate your help.

Hi Maia, I’ve used this for over a decade to wash my body, hair and face and also my toddler’s. https://naturesplus.com/products/productdetail.php?productNumber=5990. They say it’s made only with Allantoin and 500 IU of vitamin E. What do you think?

You should not use any soap or washes in the vulva or vaginal area, period. Even if they claim to be pure, or gentle, or pH balanced washes. Water and friction are all that is needed. Or a bath with epsom salt. Washes/soaps can change the pH balance, even if they claim to be pH balanced themselves, frequently making the vulva and vagina more alkaline instead of acidic, and leading to irritation, yeast overgrowth, or bacterial vaginosis.
