For a liquid format, the [Necessaire The Body Wash, Fragrance-Free](https://nontoxicnook.com/products/necessaire-the-body-wash-fragrance-free) is the most thoroughly tested option, with EWG Verified status and a dermatologist-backed surfactant system that avoids ethoxylation entirely. ## Our picks at a glance | Pick | Best for | Key certifications | Price | Details | | ------------------------------------------------------------------------------------------------- | ------------------------------------ | -------------------------------------------------------- | ----- | --------------------------------------------------------------------------------------------------- | | [Dr. Bronner's Bar Soap](/products/dr-bronners-pure-castile-bar-soap-baby-unscented) | Best overall | EWG Verified, Regenerative Organic Certified, Fair Trade | $ | [Full review](#1-dr-bronners-pure-castile-bar-soap-baby-unscented-best-overall) | | [Earth Mama Simply Non-Scents](/products/earth-mama-simply-non-scents-castile-baby-wash) | Babies and sensitive skin | EWG Verified, NSF/ANSI 305, Leaping Bunny | $ | [Full review](#2-earth-mama-simply-non-scents-castile-baby-wash-best-for-babies-and-sensitive-skin) | | [Plaine Products Unscented Body Wash](/products/plaine-products-unscented-body-wash) | Refillable packaging | EWG Verified, Leaping Bunny | $$$ | [Full review](#3-plaine-products-unscented-body-wash-best-refillable) | | [ATTITUDE Sensitive Skin Body Wash](/products/attitude-sensitive-skin-body-wash-unscented) | Budget EWG pick | EWG Verified, B Corp | $ | [Full review](#4-attitude-sensitive-skin-body-wash-unscented-best-budget) | | [Everyone 3-in-1 Soap](/products/everyone-3-in-1-soap-unscented) | Most versatile | EWG Verified, B Corp | $ | [Full review](#5-everyone-3-in-1-soap-unscented-most-versatile) | | [Avalon Organics Lavender Shower Gel](/products/avalon-organics-revitalizing-lavender-shower-gel) | Light scent from named essential oil | USDA Organic, NSF/ANSI 305 | $$ | [Full review](#6-avalon-organics-revitalizing-lavender-bath--shower-gel-best-lightly-scented) | | [Necessaire The Body Wash](/products/necessaire-the-body-wash-fragrance-free) | Premium liquid wash | EWG Verified, Leaping Bunny | $$$ | [Full review](#7-necessaire-the-body-wash-fragrance-free-best-premium) | The 1,4-dioxane problem is the defining challenge in this category. Sodium laureth sulfate (SLES) and many PEG-derived ingredients are produced through ethoxylation, which generates 1,4-dioxane as a manufacturing contaminant. It is classified as a probable human carcinogen by the EPA, it does not appear on ingredient labels, and most brands do not publish residual testing. Every product here avoids ethoxylated surfactants entirely or uses non-ethoxylated alternatives with the same cleansing function. ## What we look for **1,4-dioxane from ethoxylated surfactants.** EWG found 1,4-dioxane in roughly 45% of tested liquid soaps. The source: SLES, polysorbates, PEG compounds, and any ingredient with "-eth-" in its name. All picks here use non-ethoxylated surfactants instead: coco glucoside, sodium coco sulfate, castile soap. **Undisclosed fragrance.** "Fragrance," "parfum," and "natural fragrance" can mask phthalate carriers and synthetic musks. Every product here is fragrance-free or uses essential oils listed by INCI name. "Lavandula angustifolia extract" passes; "natural fragrance (lavender)" does not. **Parabens and problematic preservatives.** Methylparaben, propylparaben, MIT, and CMIT are excluded across all picks. MIT is EU-banned in leave-on products and implicated in contact sensitization in rinse-off formats. **Bar soap's formulation edge.** Castile bar soap uses no ethoxylated surfactants and needs no preservatives (high pH and low water activity prevent microbial growth). It removes 1,4-dioxane risk at the formulation level rather than through testing. > **Last verified August 2026** > > All picks are EWG Verified or NSF/ANSI 305 certified by Oregon Tilth. Both standards require full INCI disclosure, prohibit "fragrance" as a catch-all, and mandate independent testing. Certifications were verified in the issuer's public registry; surfactant systems were confirmed free of "-eth-" and PEG-derived ingredients. ## Our picks ### 1. [Dr. Bronner's Pure-Castile Bar Soap, Baby Unscented](/products/dr-bronners-pure-castile-bar-soap-baby-unscented): Best overall > **Best overall** > > Three certifications that resolve in their issuers' registries, a formula of six ingredients, and a bar format that eliminates the 1,4-dioxane question entirely. The clearest non-toxic pick in this category. The [Dr. Bronner's Pure-Castile Bar Soap, Baby Unscented](https://nontoxicnook.com/products/dr-bronners-pure-castile-bar-soap-baby-unscented) is as close to a formula with nothing to question as this category offers. The complete ingredient list: saponified organic coconut oil, saponified organic palm oil, water, saponified organic olive oil, saponified organic hemp seed oil, saponified organic jojoba oil, sea salt. That is seven ingredients and all of them are exactly what they appear to be. EWG Verified at Skin Deep score 1 (their highest rating), Regenerative Organic Certified, and Fair Trade from sourcing chains Dr. Bronner's controls directly. Made in Vista, California. At under $5 per bar, it is also the lowest cost per wash of anything on this list. **Lather note.** Castile soap lathers less in hard water because calcium and magnesium ions interact with soap differently than with synthetic surfactants. An acidic rinse (diluted apple cider vinegar) or a whole-house water softener restores full lather. In soft water, no adjustment is needed. **Who it's for.** Anyone who wants to remove the 1,4-dioxane and preservative questions from their body cleansing routine in a single move. Also useful for travel: TSA-compliant, no liquids bag, no bottle. ### 2. [Earth Mama Simply Non-Scents Castile Baby Wash](/products/earth-mama-simply-non-scents-castile-baby-wash): Best for babies and sensitive skin The [Earth Mama Simply Non-Scents Castile Baby Wash](https://nontoxicnook.com/products/earth-mama-simply-non-scents-castile-baby-wash) carries two of the more demanding certifications in personal care. NSF/ANSI 305 from Oregon Tilth is the organic standard for personal care products; it requires full ingredient disclosure, prohibits synthetic fragrance, prohibits synthetic preservatives, and prohibits agricultural chemicals on the restricted list. EWG Verified at Skin Deep score 1. Leaping Bunny certified cruelty-free. The formula is castile-based: organic coconut castile as the primary surfactant, with organic shea butter, organic calendula, and organic aloe vera. No sulfate surfactants, no ethoxylated ingredients, no phthalates, no synthetic fragrance. Full INCI list is published on the brand's product page. NSF/ANSI 305 is the same certifying body (Oregon Tilth) that issues USDA Organic certification for food, applying the same third-party auditing standard to personal care product formulation. **Who it's for.** Newborns through toddlers and adults with eczema, contact dermatitis, or fragrance sensitivity. Used in hospital NICUs for newborn skin. Accepted by the National Eczema Association. The 34 fl oz pump bottle has a lower cost per ounce than most competitors at a similar certification level. ### 3. [Plaine Products Unscented Body Wash](/products/plaine-products-unscented-body-wash): Best refillable The [Plaine Products Unscented Body Wash](https://nontoxicnook.com/products/plaine-products-unscented-body-wash) is the only product in this lineup sold in a refillable aluminum bottle. The model: you keep the pump, return the empty bottle in a prepaid envelope, and receive a full replacement. No plastic enters the waste stream at any point. EWG Verified and Leaping Bunny certified. Surfactant is coco glucoside, a coconut-derived non-ionic surfactant that is not ethoxylated and carries no 1,4-dioxane risk. Preserved with leuconostoc/radish root ferment filtrate, a natural preservative with no paraben or isothiazolinone concern profile. No synthetic fragrance, no sulfates. **Who it's for.** Households committed to zero-waste who are willing to pay a premium for a refill model. The per-ounce cost decreases with each refill cycle because the pump hardware is reused. ### 4. [ATTITUDE Sensitive Skin Body Wash, Unscented](/products/attitude-sensitive-skin-body-wash-unscented): Best budget The [ATTITUDE Sensitive Skin Body Wash, Unscented](https://nontoxicnook.com/products/attitude-sensitive-skin-body-wash-unscented) is EWG Verified at the lowest price point in this guide. Produced by a B Corp headquartered in Montreal with Leaping Bunny certification. The surfactant base is coco glucoside and cocamidopropyl betaine. Cocamidopropyl betaine is an amphoteric surfactant derived from coconut oil; it is produced without ethoxylation and carries no 1,4-dioxane risk. No synthetic fragrance, no parabens, no MIT or CMIT. **Who it's for.** Budget-conscious households who want EWG Verified status in a 32 fl oz bottle at wide retail availability. ### 5. [Everyone 3-in-1 Soap, Unscented](/products/everyone-3-in-1-soap-unscented): Most versatile The [Everyone 3-in-1 Soap, Unscented](https://nontoxicnook.com/products/everyone-3-in-1-soap-unscented) functions as body wash, shampoo, and bubble bath in one bottle. EWG Verified. Made by EO Products, a certified B Corp. Surfactant is sodium lauroyl methyl isethionate, a mild synthetic surfactant that is not produced via ethoxylation and carries no 1,4-dioxane risk. **Ingredient note.** The formula includes lavandin extract at a functional quantity. Lavandin is a plant-derived botanical listed under its INCI name (lavandin extract), not masked under "fragrance." It is not a disqualifier under the site's undisclosed-fragrance criterion, which targets catch-all "fragrance" and "parfum" entries. Households with severe fragrance sensitivity may prefer a formula with no botanical extracts at all. **Who it's for.** Families with children who want a single product for all three uses. Also useful for travel minimalists. ### 6. [Avalon Organics Revitalizing Lavender Bath & Shower Gel](/products/avalon-organics-revitalizing-lavender-shower-gel): Best lightly scented The [Avalon Organics Revitalizing Lavender Bath & Shower Gel](https://nontoxicnook.com/products/avalon-organics-revitalizing-lavender-shower-gel) is the only lightly scented option in this guide. Certified to NSF/ANSI 305 by Oregon Tilth and carrying USDA Organic certification for its botanical content. The surfactant is sodium coco sulfate, which is derived from coconut oil but is not the same compound as sodium lauryl sulfate; it is not ethoxylated. The scent is lavender essential oil, disclosed on the ingredient list as lavandula angustifolia extract, not as "fragrance" or "natural fragrance." **Who it's for.** Households that want light scent from a disclosed essential oil rather than a "fragrance" masking entry. One of the most affordable NSF/ANSI 305 certified body washes available. ### 7. [Necessaire The Body Wash, Fragrance-Free](/products/necessaire-the-body-wash-fragrance-free): Best premium The [Necessaire The Body Wash, Fragrance-Free](https://nontoxicnook.com/products/necessaire-the-body-wash-fragrance-free) is the most dermatologically focused formula on this list. EWG Verified at Skin Deep score 1. Leaping Bunny certified. Formulated with niacinamide (three molecular weights), mandelic acid (AHA), and ceramides alongside the cleansing system. The surfactant is sodium lauroyl methyl isethionate, not ethoxylated, no 1,4-dioxane risk. No synthetic fragrance, no parabens, no MIT or CMIT. The formulation goes beyond cleansing into skin barrier support, which is a real distinction and not marketing copy: niacinamide is well-supported by dermatology literature for barrier function, and ceramides replenish what water and surfactants deplete. **Who it's for.** Adults who want body wash to function as skincare, not just a cleanser. More expensive per ounce than the others here; the premium is for formulation complexity, not packaging. ## What we passed on **Meliora Unscented Bar Soap** passes the disqualifier screen and is EWG Verified. During research, the unscented variant showed out-of-stock on the brand's own site and no active Amazon listing. Worth reconsidering when inventory is confirmed stable. **ATTITUDE Bar Soap:** Amazon search for ATTITUDE bar soap returns only scented variants (Watercress, Coconut and Jojoba). Because an unscented SKU with full INCI disclosure could not be confirmed, and because the fragrance criterion requires verification of the specific SKU in question, we did not include it. A clearly fragrance-free ATTITUDE bar soap with full ingredient disclosure would be a strong addition to this list. **Acure Brightening Body Wash:** Frequently recommended in non-toxic communities but holds no EWG Verified status or NSF/ANSI 305 certification. No published residual 1,4-dioxane testing. Removed from consideration until certification or independent testing is added. ## FAQ ### Is bar soap more non-toxic than liquid body wash? Not automatically, but castile bar soap has a structural advantage: it requires no preservatives and is made without ethoxylated surfactants, which eliminates the 1,4-dioxane risk at the formulation level. Liquid body wash can meet the same standard if it uses non-ethoxylated surfactants and discloses full INCI ingredients, as all seven picks here do. The bar format is the simpler path to zero 1,4-dioxane risk; the liquid format requires more attention to the specific surfactant used. ### What is 1,4-dioxane and why does it matter in soap? 1,4-dioxane is a manufacturing byproduct that forms during ethoxylation, the industrial process used to produce sodium laureth sulfate (SLES) and many PEG-derived ingredients. It is classified as a probable human carcinogen by the EPA. It is not an intentional ingredient, so it does not appear on the label. Brands can remove it through vacuum stripping during production, but most do not publish residual testing results. Products here use surfactants produced without ethoxylation, which avoids the issue at the source rather than requiring ongoing testing to manage a byproduct. ### Does "fragrance-free" mean unscented? The terms are not interchangeable. "Unscented" can legally mean that masking fragrance was added to cover a natural product odor. "Fragrance-free" is more specific but still does not prevent listing "fragrance" as an ingredient under US labeling rules. The EWG Verified standard and NSF/ANSI 305 both require full INCI disclosure and prohibit the generic "fragrance" entry, which is why this guide uses those certifications as a minimum floor. When a body wash is EWG Verified and lists no "fragrance" or "parfum," that means fragrance was actually not added. ### Can castile bar soap be used as shampoo? Some people use it, but it typically requires an acidic rinse (diluted apple cider vinegar) to rebalance scalp pH. Pure castile soap has a pH between 8.9 and 9.5; the scalp's natural pH is 4.5 to 5.5. Without the acidic rinse, particularly in hard water, hair often feels waxy or rough. A pH-balanced shampoo formulated for hair works better for most people. ### Are all sulfate-free body washes safer? Sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) are often grouped together as "sulfates," but they have different concern profiles. SLS is not produced by ethoxylation and carries no 1,4-dioxane risk; it is a known skin irritant at high concentrations but is not classified as a carcinogen concern. SLES is ethoxylated and carries 1,4-dioxane byproduct risk. Avoiding all sulfates conflates a real concern (SLES and 1,4-dioxane) with one that is less clear-cut (SLS and irritation). This guide focuses on the ethoxylation problem, not sulfate avoidance as a general rule. **Sources:** 1.
