Switching to an all natural liquid body soap should feel like a relief, not a chemistry lesson. You want something that cleans without mystery ingredients, leaves your skin happy, and doesn’t require a degree to read the label.

We’ve looked at the crowd favorites and the hidden gems to find the best all natural liquid body soap for your skin type, your routine, and your values.
Our Picks at a Glance
How To Choose The Best All Natural Liquid Body Soap
Finding a truly all natural liquid body soap means looking past the fancy bottle and checking what is actually inside. Many brands use words like “natural” or “gentle,” but the real test is in the ingredients list and the certifications behind them. Here is what to keep an eye on.
Understand the Base: Castile vs. Body Wash
Most all natural liquid body soaps fall into two camps. Castile soap is the traditional, plant-oil based soap (usually olive, coconut, or hemp) with no synthetic detergents. A body wash can be all natural too, but it often relies on a blend of plant-derived cleansers. If you want the simplest, most transparent formula, castile is your go-to. If you prefer a thicker gel that feels more like a conventional shower gel, a natural body wash might suit you better.
Check the Certifications
A bottle that says “natural” doesn’t mean much on its own. Look for seals like USDA Organic, Oregon Tilth Certified Organic, or EWG Verified. These third-party certifications mean the ingredients and processes have been checked by an independent body. Fair Trade certification matters too — it ensures the people growing the ingredients were paid and treated fairly.
Know What to Avoid
The whole point of all natural is skipping the stuff you don’t want. That means no synthetic fragrances, no parabens, no sulfates like SLS (sodium lauryl sulfate) or SLES (sodium laureth sulfate), and no artificial dyes. If you see a long list of chemical names you cannot pronounce, put it back. Also, some “natural” soaps still contain palm oil, which has environmental concerns — look for a “palm oil free” label if that matters to you.

In‑Depth Reviews
1. Dr. Bronner’s Pure-Castile Magic Liquid Soap – Peppermint, 32 oz
Our pick — over 4.5★ from 70,500+ verified ratings; the strongest balance of quality and price.
The legendary bottle that practically runs your whole household with one ingredient list.
This is the soap that started the modern natural-cleaning movement for a reason. Dr. Bronner’s is made with over 70% certified organic and fair trade ingredients, and it is 3x more concentrated than most liquid soaps. That means one 32-ounce bottle stretches further — you can use it as a body wash, face cleanser, shampoo, laundry soap, pet wash, and even vegetable cleaner. The peppermint version is the most popular, and the scent is described as “really invigorating” by owners who also note it doesn’t bother sensitive skin. The lather is rich and thick, and it rinses clean without leaving any film behind.
It weighs only 1 pound, making it 2.3 pounds lighter than the BAMBOO AND BIRCH 32-ounce castile, which is a nice bonus if you are moving bottles around your shower and laundry room. The thing everyone raves about is the quality — it is the most praised aspect by a wide margin, followed closely by the fragrance. Owners consistently call out how a small amount goes a long way, so the higher upfront cost pays off over time.
What Wins People Over
- 18-in-1 versatility replaces multiple bottles
- Concentrated formula — a little goes a long way
- Certified organic and fair trade ingredients
- Rich lather that rinses clean with no film
The Honest Trade-Offs
- Peppermint tingling may be too strong for very sensitive skin
- Liquid consistency is thinner than a typical body wash gel
Your go-to if: you want one soap that can do it all — body, hair, laundry, dishes — with a trusted organic label.
Think twice if: you strongly prefer a thick shower gel texture or dislike a cooling sensation on your skin.
2. BAMBOO AND BIRCH Pure Castile Soap Liquid, Citrus Grapefruit, 32 oz
A palm-oil-free castile that punches above its price tag with a bright citrus personality.
You get more soap per dollar with this 32-ounce bottle than with Dr. Bronner’s 1-pound bottle — it weighs 2.34 pounds, so you buy less often. One owner who has “tried several Castile soaps in the past” calls it their favorite for the price. It is certified palm oil free and made from 100% natural ingredients, so it works as a multi-purpose cleaner for body, face, hair, dishes, and laundry. The citrus grapefruit scent smells refreshing at first, but a few buyers report the fragrance fades after the first couple of pumps — the rest of the 32 ounces is essentially unscented.
Cleaning performance is the top praised aspect, with fragrance close behind. Owners love that the large bottle lasts for months, even with frequent use. It is versatile enough for hand soap in the bathrooms, body wash in the shower, and as a gentle dish cleaner. Just note that some found it didn’t work well as a shampoo, so keep it as a body and home cleaner for best results.
Why It Stands Out
- Palm oil free with all natural ingredients
- Large 32 oz bottle at a budget-friendly price point
- Multi-purpose for body, home, and laundry
A Note on the Scent
- Grapefruit fragrance fades quickly after the first few uses
- Not recommended as a shampoo by some users
Reach for this if: you want a palm-oil-free castile with a big bottle and a bright start, and you don’t mind if the scent settles into neutral.
Look elsewhere if: you need a strong, lasting fragrance throughout the entire bottle.
3. WHOLENATURALS Pure Castile Soap Liquid, Unscented, 64 Fl Oz
The EWG-verified powerhouse for anyone who wants zero fragrance and maximum certifications.
This is the only soap on the list that is EWG Verified and certified palm oil free on Amazon, making it a top choice for the label-conscious buyer. It is also certified organic, non-GMO, and vegan. The 64-ounce bottle is the largest in our lineup, and because the formula is 2-3x more concentrated than regular soaps, a single fill lasts an impressively long time. The unscented formula contains no essential oils, so it is truly neutral — perfect for blending your own scents or for those who react to any fragrance at all. The ingredient list includes organic prickly pear, argan, jojoba, almond, and hemp oils, so it is designed to be hydrating without clogging pores.
Quality is the most mentioned positive by a massive margin, and owners frequently note how gentle and effective it is for sensitive skin, eczema, and baby care. One owner said it leaves skin feeling “squeaky clean” without dryness. The bottle is heavy at 8 pounds for the full package, but that is the trade-off for getting a gallon-sized supply. A few owners note that the consistency is slightly thinner than some other castiles, but the lather is still generous.
The Certifications That Count
- EWG Verified for ingredient safety
- Certified palm oil free and organic
- 64 oz of concentrated soap — lasts many months
- Blend of luxury oils for hydration
What to Expect
- Unscented — no natural essential oil aroma at all
- Large, heavy bottle may be hard to pour from
Ideal for the purist: you want the most certified, concentrated, unscented castile soap available, and you have the cabinet space for a bulk refill.
Not for you if: you prefer a scented shower experience or dislike thin liquid textures.
4. Dr. Woods Raw African Liquid Coconut Papaya Black Soap, 32 Fl Oz
A West African-inspired black soap that gently exfoliates while shea butter keeps skin soft.
Dr. Woods takes a different approach than the castile soaps on this list. It is a traditional African black soap formula made with natural ingredients indigenous to West Africa, including Fair Trade shea butter that is sustainably harvested from Ghana. It naturally exfoliates as it cleans, so you get a gentle scrub without harsh microbeads or synthetic granules. The coconut and papaya fragrance is the most talked-about aspect, and owners say it leaves a lasting, pleasant scent that isn’t overpowering. One owner called it “clean, refreshing, and smells nice,” and many appreciate how it rinses clean without any film residue.
The fragrance and cleansing performance are the top two praised aspects, and owners with skin flaking issues report it helps smooth and soften the skin. The 32-ounce bottle weighs 2 pounds. One owner found it left a slight film, but this isn’t the common experience — most say it rinses cleanly. The lather is mixed: some say it foams well, others say it is low-suds.
What Makes It Different
- Natural exfoliation from black soap ingredients
- Fair Trade shea butter for moisture
- Pleasant coconut papaya scent that lingers
- 32 oz bottle at a fair value
Things to Know
- Lather can be inconsistent — some find it low-suds
- A minority report a slight film residue
Best for: anyone who wants a naturally exfoliating body wash with a warm, tropical scent and Fair Trade ingredients.
skip it if: you need a high-lather soap or dislike any hint of residue on your skin.
5. WEBE Naturals Pure Unscented Castile Soap Refill, 64 Oz
The unscented refill cylinder that keeps your soap pumps full and your wallet happy.
The scent is a mixed point — because it is truly unscented, it has a faint natural smell that some find slightly different from a fragranced soap. The consistency is also noted as slightly runnier than some other castiles, but the lather is described as good. It is a cost-effective choice if you go through soap quickly, and the large format reduces plastic waste compared to buying multiple smaller bottles.
The Refill Advantage
- 64 oz refill — great value for frequent users
- Organic olive oil base is gentle and moisturizing
- Vegan, non-GMO, gluten-free certified
- Multi-use for body, home, and laundry
Before You Buy
- Unscented — if you want a fragrance, this isn’t it
- Consistency is thinner than some castiles
Reach for this if: you want a massive unscented refill to cut down on packaging and cost per ounce.
Think twice if: you enjoy a scented shower or prefer a thicker, gel-like body wash.
6. Natural Body Wash for Women, Men & Kids – Organic Lemon Rosemary, 12oz (Pack of 2)
A pH-balanced body wash that smells like a lemon grove and treats sensitive skin gently.
Most natural soaps are naturally alkaline, but this body wash is formulated to a pH of 5.5, which is close to your skin’s natural level. That means it is less likely to disrupt your skin barrier or cause that tight, dry feeling after washing. The lemon rosemary scent is the most talked-about positive, described as refreshing and evocative of a classic lemon-up aroma. The formula is sulfate-free, paraben-free, and packed with soothing aloe vera juice, making it suitable for anyone with eczema or general sensitivity. The pack of two 12-ounce bottles is convenient for splitting between shower and sink, or for sharing.
Buyers praise the fragrance and how well it cleans, but the consistency gets the most mixed feedback. Several owners say it is “rather thin and runny” even after shaking — a surprise if you are used to a thick gel. On the upside, owners mention it leaves skin feeling soft and not dried out, and some use it successfully as a shampoo. If you can accept the thin texture, the ingredients and pH balance are tough to top at this price.
The Smart Feature
- pH 5.5 formula supports healthy skin barrier
- Sulfate-free and packed with aloe vera
- Refreshing lemon rosemary scent
- Pack of 2 offers good value
The Common Complaint
- Very thin, runny consistency — not a gel
- Some find it less moisturizing than conventional soaps
Ideal for: anyone with sensitive or eczema-prone skin who wants a pH-correct body wash with a pleasant natural scent.
Not for: anyone who prefers a thick, lather-rich shower gel and dislikes watery textures.
7. Certified Organic Lemongrass Body Wash – Paraben & Sulfate Free – All Natural – 8 oz
It carries Oregon Tilth Certified Organic certification, verifying every plant-derived ingredient. Organic lemongrass oil, coconut oil, aloe vera, and shea butter make it gentle yet effective for all skin types. One owner found exactly what they were looking for: “I was looking for a more natural and safe ingredient body wash. I really like the smell and feel of this body wash.” It works for daily use on face, body, feet, and nails for men, women, and kids.
The lemongrass scent is the top praised feature, described as refreshing and cooling after outdoor activity. Cleansing performance also earns high marks. Trade-offs: the 8-ounce bottle is smaller than most, and the lather is low-suds due to no SLS. Some are surprised by the low lather at first, but owners quickly adjust and love the clean, soft feel.
The Certifications
- Oregon Tilth Certified Organic
- Safe for acne, eczema, and psoriasis
- Organic lemongrass and coconut oil
- Great cooling sensation after outdoor activity
The Small Print
- 8 oz bottle is smaller than competitors
- Low suds — no foaming agents, so it won’t bubble like you’re used to
Your pick if: you want a certified organic body wash that directly targets skin conditions like eczema and you don’t mind a low-lather rinse.
pass on it if: you need a large bottle size or prefer a rich, foamy lather in the shower.
Understanding the Specs
Castile vs. Body Wash
Castile soap is the traditional, all-natural soap made from plant oils like olive, coconut, or hemp. It does not use synthetic detergents or foaming agents. A body wash, even an all-natural one, may use a blend of plant-derived cleansers for a thicker gel feel. If you want the most transparent, single-ingredient-list formula, go castile. If you prefer a consistency closer to a conventional shower gel, look for a natural body wash.
pH Balance
Your skin has a natural pH around 5.5. Many traditional soaps are alkaline (higher pH), which can disrupt your skin’s protective barrier and lead to dryness or irritation. A pH-balanced body wash is formulated to match your skin’s natural level, making it a better choice for sensitive, eczema-prone, or dry skin types.
Concentration & Dilution
A “concentrated” or “3x concentrated” castile soap means you are supposed to dilute it with water before use. For body washing, usually a few drops on a loofah is enough. For household cleaning, you mix it with water. A non-concentrated body wash is used straight from the bottle. Understanding concentration helps you compare value across different bottle sizes.
Third-Party Certifications
An organic or natural claim on the front label is not enough. Look for seals like USDA Organic, Oregon Tilth, or EWG Verified — these mean an independent organization checked the ingredients and manufacturing process. “Palm oil free” is a separate claim that matters if you are concerned about deforestation. Fair Trade certification ensures the raw ingredients were sourced ethically.
