10 Safe Non-Toxic Dish Soap Brands (2025 Review) (2025)

You want an effective and truly safe non-toxic dish soap. One that cleans your dishes without coating them (or your hands) in questionable chemicals. But with brands tossing around terms like “natural,” “green,” and “chemical-free,” how do you know which ones actually live up to the hype? That’s exactly why I bought, tested, and ranked the best non-toxic dishwashing soaps in 2025 to find out which ones are natural, effective, and worth your money.

For this research-backed, hands-on review, I cross-checked every formula against EWG ratings, and read through all the ingredient lists, making sure they’re free from sulfates, phthalates, synthetic fragrances, and other harsh chemicals. I also verified all certifications and contacted brands for clarifications when needed. Lastly, each chemical-free dish soap went through real-life testing for cleaning power, grease removal, and skin sensitivity. Check out the complete testing process>

These 10 safest dishwashing liquid, solid, and pod options made the cut. Spoiler alert: You’ll be surprised by the “safest dish soaps“ that didn’t!

You wouldn’t drink dish soap straight from the bottle (we hope!). But every time you eat off a plate or sip from a glass, some residues might still be there. A study published in Environmental Chemistry Letters examined the retention of detergent residues on various tableware materials after handwashing.

The researchers found that residues of the surfactant sodium dodecyl sulfate and the biocide 1,2-benzisothiazol-3(2H)-one remained on dishes post-washing, with higher amounts detected on materials with greater surface roughness, such as wood, compared to smoother surfaces like glass.

So, to put it simply, if you’re using a dish soap with SLS, phthalates, or artificial fragrances, you could be ingesting trace amounts with every meal. Over time, even small exposures to these chemicals can add up.

Ever washed dishes and noticed your hands feeling dry or irritated? That’s because many dishwashing liquid brands contain harsh detergents that strip away natural oils, leaving your skin vulnerable.

According to the American Contact Dermatitis Society, ingredients like SLS, Methylisothiazolinone, and artificial fragrances are among the most common skin irritants. Even worse, frequent exposure can lead to dermatitis, allergic reactions, and, in some cases, even long-term skin sensitivity. The fix? A chemical-free dish soap that cleans without nasty side effects.

You’ve probably heard the term “non-toxic dish soap brands,” but what does that really mean? Before we jump to my review of the best natural dishwashing liquid and solid soap options, let’s go over some of the basics.

What Is Non-Toxic Dish Soap?

Non-toxic dish soap is a safer and healthier alternative to conventional dishwashing liquids. It is free from harsh chemicals that can harm your health or the environment.

Traditional dish soaps often contain synthetic detergents, artificial fragrances, and petroleum-based ingredients. In contrast, a truly safe, non-toxic dish soap uses plant-based cleansers and biodegradable ingredients. It features gentle, skin-friendly formulas that are safer for daily use.

Non-toxic dish soap effectively removes grease and grime without leaving harmful residues. This means you won’t unknowingly ingest toxic chemicals with your next meal.

Chemical-free dish soaps also break down safely in water systems, reducing environmental harm. Choosing these products helps protect both your family and the planet.

If you’ve ever wondered what non-toxic dish soap is, the answer is simple. It’s a dish soap that cleans well without compromising your health or the environment.

To find the best natural dishwashing liquid in 2025, start by knowing what to look for. More importantly, understand what ingredients to avoid.

What Makes Conventional Dish Soap Toxic?

SLS & SLES

Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) are the reason your dish soap foams so nicely. That thick, satisfying lather might make you feel like your dishes are getting an extra-deep clean, but in reality, these harsh detergents are known skin irritants. According to the Journal of the American College of Toxicology, SLS can strip your skin’s natural oils, leading to dryness, irritation, and even allergic reactions over time. If you’ve ever washed a sink full of dishes and ended up with red, cracked hands, you can probably thank SLS for that.

The worst part is that SLES is often contaminated with 1,4-dioxane, a chemical classified as a probable human carcinogen by the EPA and the National Toxicology Program. A report by the FDA found 1,4-dioxane in nearly half of the personal care products tested, meaning if your dish soap isn’t labeled non-toxic or chemical-free, there’s a good chance you’re exposing yourself to it daily. And since this stuff doesn’t easily biodegrade, it’s also a major water pollutant, harming fish and aquatic life long after it goes down your drain.

Fragrance & Phthalates

If your dish soap smells like a tropical vacation, there’s a high chance it’s hiding phthalates—a group of chemicals used to make fragrances last longer. As we’ve previously mentioned, Phthalates are known endocrine disruptors, meaning they mess with your hormones. Studies from the Endocrine Society have linked phthalate exposure to infertility, developmental issues in children, and even increased risks of certain cancers.

Worse yet, companies are not required to list phthalates on product labels. Instead, they often hide phthalates under the vague term “fragrance” or “parfum.” This creates a loophole that allows hundreds of unregulated chemicals to go unnoticed.

The CDC has found that over 90% of Americans have detectable levels of phthalates in their bodies. Long-term exposure to phthalates has been linked to lower sperm counts, thyroid dysfunction, and metabolic disorders.

If you want a safe, non-toxic dish soap, choose brands that use essential oils for scent. Better yet, opt for fragrance-free dish soaps to avoid any hidden chemicals.

Triclosan

For years, brands marketed “antibacterial” dish soap as a superior way to kill germs.

In reality, one of their main active ingredients has been banned in hand soaps by the FDA. This is due to serious health risks associated with the ingredient.

Unfortunately, it’s still allowed in some dish soap brands. Research shows that it disrupts thyroid function and contributes to antibiotic resistance.

The World Health Organization has even flagged triclosan as a contributor to superbugs. These superbugs could make infections harder to treat in the future.

Beyond the human health risks, triclosan is also an environmental nightmare. A study published in Environmental Pollution found that triclosan disrupts aquatic ecosystems by harming algae. That’s the foundation of the food chain. Once it enters waterways, it lingers, building up in fish and marine life. So, if you see “antibacterial” on a dish soap label, that’s your cue to put it back on the shelf and reach for a safe, non-toxic dishwashing liquid instead.

Chlorine & Ammonia

Ever felt lightheaded or had trouble breathing while scrubbing your dishes? Your dish soap might be releasing chlorine or ammonia vapors into your kitchen air. These chemicals are used in heavy-duty degreasers. But when they are mixed (even accidentally), they create chloramine gas. That is a highly toxic substance that can cause severe respiratory issues.

According to the American Lung Association, repeated exposure to chlorine fumes can trigger asthma, chronic bronchitis, and long-term lung damage. A study in JAMA Network Open even found that regular exposure to chlorine-based cleaning products caused lung function decline equivalent to smoking a pack of cigarettes a day. I wouldn’t risk it when there are so many chlorine-free and 100% non-toxic dishwashing soap brands available on the market.

Dyes & Artificial Colors

Ever wonder why some dish soaps are bright blue, neon green, or deep orange? Spoiler alert: That’s not natural. Many dishwashing liquid brands use synthetic dyes made from petroleum byproducts that serve absolutely no purpose. Other than making soap look more appealing, of course.

Beyond being unnecessary, artificial colors have been linked to health concerns. The California Office of Environmental Health Hazard Assessment found that synthetic dyes can contribute to hyperactivity in children. Some studies suggest they may trigger allergic reactions. Worse, certain food dyes contain trace amounts of lead, arsenic, and mercury, which can accumulate in the body over time. Since soap is something you use every day, it’s best to opt for a chemical-free dish soap without any artificial colors.

Methylisothiazolinone & Benzisothiazolinone

These two preservatives sound are common in dish soaps because they prevent bacteria growth, but they come with serious risks. The European Commission’s Scientific Committee on Consumer Safety has flagged MIT as a known skin allergen. Multiple studies show it can cause severe contact dermatitis, especially for people with sensitive skin.

Even more concerning, animal studies suggest that MIT might have neurotoxic effects, potentially harming brain function with repeated exposure. Many of the best non-toxic dish soap brands in 2025 have already removed these preservatives in favor of safer alternatives. If your dish soap isn’t labeled MIT-free, it’s probably best to switch to one that is.

The Safest Non-toxic Dishwashing Soap Ingredients You Can Trust

If you’ve made it this far, you already know that many dish soap brands sneak in some pretty nasty chemicals. But just because a label says “natural” or “green” doesn’t automatically mean it’s a safe dish soap. Greenwashing—when companies use misleading marketing to make products seem eco-friendly or non-toxic—is rampant in the cleaning industry. So, how do you separate the truly non-toxic dishwashing liquid from the ones just pretending? Let’s break it down.

Plant-Based Surfactants

Surfactants (the ingredients that break down grease and grime) are essential in dish soap, but not all surfactants are created equal. Many conventional brands rely on harsh detergents like SLS and SLES, which strip oils from your skin and may be contaminated with harmful byproducts. Instead, look for plant-based Chemical dish soap alternatives like:

• Coco-glucoside – Derived from coconut and sugar, this mild surfactant is effective yet gentle on the skin.
• Decyl glucoside – A plant-derived cleanser that’s biodegradable, hypoallergenic, and safe for sensitive skin.
• Sodium coco sulfate – A milder cousin of SLS that offers a good lather without the harsh side effects.

These surfactants clean just as well as synthetic chemicals but without skin irritation or environmental damage.

Natural Essential Oils for Fragrance

If you love a fresh-smelling dish soap but want to avoid the hidden dangers of synthetic fragrances, look for brands that use 100% natural essential oils instead. Citrus oils like lemon, orange, and grapefruit cut through grease naturally, while lavender and eucalyptus offer antibacterial benefits. Not only do they smell amazing, but they also provide a safer alternative to phthalate-laden artificial scents.

Keep in mind that even natural fragrances can trigger allergies in some people, so if you have ultra-sensitive skin, opting for an unscented, non-toxic dish soap is your best bet.

Organic, Biodegradable Preservatives

Preservatives are necessary to keep dish soap from growing mold or bacteria, but many conventional brands use methylisothiazolinone (MIT) and benzisothiazolinone (BIT)—which have been linked to skin allergies and even neurotoxicity. Instead, look for organic, plant-based preservatives like:

• Radish root ferment – A natural antimicrobial derived from fermented radish roots.
• Rosemary extract – Acts as both a natural preservative and an antioxidant.
• Potassium sorbate & sodium benzoate – Food-grade preservatives that are much safer than synthetic alternatives.

If your best non-toxic dish soap choice contains preservatives, they should be biodegradable and naturally derived—not a hidden chemical cocktail.

Non-GMO, Sulfate-Free, Phthalate-Free Formulations

The best chemical-free dish soap brands will proudly display their commitment to non-GMO ingredients, sulfate-free cleansing agents, and zero phthalates. Non-GMO ingredients ensure that synthetic pesticides and genetic modifications aren’t lurking in your soap, while sulfate-free formulas reduce the risk of skin irritation. Phthalates—often hidden in synthetic fragrances—should also be avoided due to their hormone-disrupting effects.

Want to be extra safe? A certified safe dish soap labeled “fragrance-free, sulfate-free, and non-GMO” is a great place to start.

Eco-Friendly Certifications & Labels to Trust

1. USDA Organic: If a dish soap carries the USDA Organic seal, it means at least 95% of its ingredients are certified organic—meaning no synthetic pesticides, GMOs, or toxic additives. While this certification is more common in food products, some organic, chemical-free dish soaps have met the standards.

2. EWG Verified: The Environmental Working Group (EWG) rates thousands of household products for safety. If dish soap is EWG Verified, it means it has zero concerning chemicals, full ingredient transparency, and meets strict health and environmental safety standards. The EWG’s database is a great place to check if a product is truly safe.

3. EPA Safer Choice: The EPA Safer Choice label ensures that a product meets high safety and environmental standards, meaning it contains no toxic ingredients that could harm human health or aquatic life. This certification is especially important for dish soap since it eventually rinses down the drain and into waterways.

4. Leaping Bunny (Cruelty-Free): Even if a dish soap is labeled “natural” or “eco-friendly,” it might still be tested on animals. The Leaping Bunny certification guarantees that no animal testing is conducted at any stage of production. Since dish soap doesn’t need to be tested on animals to be effective, choosing a cruelty-free dishwashing liquid is an easy, ethical switch.

5. Made Safely Certified: One of the most rigorous certifications, Made Safe Certified, means a product has been screened for over 6,500 toxic chemicals and is 100% free from harmful substances like parabens, phthalates, and petroleum-based ingredients. If a safe, non-toxic dish soap brand has this seal, you can trust it’s one of the safest options available.

Dish Soap Brands I Don’t Recommend

In my opinion, if you are looking for the best dish soap without harmful chemicals, these brands aren’t it. I am sad to report that there are some of my previously favorite chemical-free dish soap brands in this list after their recent reformulations.

• Dawn is awful. While their ingredient list isn’t fully transparent (red flag!), their safety data sheets reveal a mix of SLES, artificial fragrances (likely hiding phthalates), synthetic dyes, and preservatives like methylisothiazolinone. Not exactly the ‘gentle on hands’ formula, they claim.
• Palmolive loves to slap words like “eco” and “pure” on their bottles, but don’t be fooled. Their formulas still contain sodium laureth sulfate, synthetic dyes, and fragrance. Their so-called “Pure + Clear” line? Just another marketing trick with the same old questionable ingredients. Hard pass.
• Fairy dish soap is toxic and far from safe or chemical-free. The ingredient list contains Sodium laureth sulphate, Alcohol denat, Lauramine oxide, C9-11 pareth-8, Sodium chloride, and many more chemicals that are considered toxic. There is a full study you can check for more information.
• Vel Pure & clear is also on my “no” list. The Danish Consumer Council THINK Chemicals analyzed it and rated it with a “C “ because it contains allergenic preservatives benzisothiazolinone and methylisothiazolinone.
• Target’s Up & Up dish soap is easy on your wallet but loaded with SLES, synthetic fragrance, and preservatives such as methylchloroisothiazolinone and methylisothiazolinone. Your dishes deserve better.
• 365 Dish Soaps recently added sodium laureth sulfate, cocamidopropyl betaine, and benzisothiazolinone to their formulas, so they are far from non-toxic dish soap brands.
• Aunt Fannie’s “safest dishwashing liquid” contains cocamidopropyl betaine, which is a mild irritant. While the rest of their cleaning line is non-toxic and fantastic to use, this one doesn’t make the cut for the safest dish soap.
• Biokleen is a disappointment. Back in the day, around 10 years ago, they claimed to have chemical-free dish soaps backed by MSDS. However, Biokleen, after their most recent reformulation, the current ingredient list contains cocamidopropyl betaine, lauramine oxide, and C10-16 alkyl glucoside.
• Caldrea dish soaps contain methylisothiazolinone, benzisothiazolinone, and synthetic fragrance. So, sadly, they are not a chemical-free dish soap brand.
• Dapple dish soap sounds promising with its use of alkyl polyglucoside, a safe and biodegradable surfactant. However, it takes a turn for the worse with the addition of tetrasodium iminodisuccinate (rated a C by the EWG), synthetic fragrance, and benzisothiazolinone, a known skin irritant and potential allergen.
• Despite the name, Eco-Max dish soap contains sodium laureth sulfate (SLES), a surfactant that’s often contaminated with 1,4-dioxane, a possible carcinogen. They also use cocamidopropyl betaine. The bottom line? There are better, truly non-toxic dishwashing soap options out there.
• I used to be a huge fan ofEarth Friendly Products because the ECOS clean formula contained just water, salt, organic grapefruit oil, and a coconut-based surfactant. Unfortunately, their updated ingredient list now includes cocamidopropyl betaine, sodium coco-sulfate, cocamidopropylamine oxide, phenoxyethanol, and methylisothiazolinone.
• Why I like many products from Sky Organics, but their dish soap isn’t one of them, as it contains Phenoxyethanol. While it might not be the worst preservative out there, it can cause an array of side effects.
• Grab Green’s newly reformulated dish liquid includes sodium laureth sulfate (SLES) and cocamidopropyl betaine—both of which are known skin irritants and potential environmental pollutants.
• Honest Company uses sodium benzoate, cocamidopropylamine oxide, phenoxyethanol, sodium coco-sulfate, and cocamidopropyl betaine—ingredients that range from mild irritants to synthetic preservatives with potential health concerns. While it’s a step up from its earlier versions, it’s still not making the cut for the safest dish soaps.
• J.R. Watkins foaming dish soap is packed with synthetic fragrances, artificial dyes, and other standard toxic culprits that you don’t want on your dishes—or your hands.
• Method dish soap includes synthetic fragrances, artificial colorants (though phthalate-free), synthetic preservatives, and methylisothiazolinone—an ingredient linked to skin irritation and potential neurotoxicity.
• Sapadilla Lovely Liquid Dish Soap has cocamidopropyl betaine, a surfactant that can trigger skin irritation and is often contaminated with unwanted byproducts. For a brand that markets itself as natural, this ingredient earns it a spot on the “avoid” list.
• Shaklee is relatively known for their “safe” dish soaps, but unfortunately, their formula doesn’t hold up under scrutiny. Their dishwashing liquid contains Poly(oxy-1,2-ethanediyl), .alpha.-sulfo-.omega.-hydroxy-, C10-16-alkyl ethers, which may be contaminated with 1,4-dioxane—a possible carcinogen. Additionally, the formula includes tetrasodium EDTA and C10-16-alkyl glycosides, both of which receive a concerning “C” rating from the EWG.
• Trader Joe’s may be a go-to for organic snacks, but their dish soap remains a bit of an enigma. They don’t disclose their full ingredient list, which is a major red flag when it comes to transparency. What do we know? The formula contains artificial colors. Without full disclosure, there’s no way to know what else might be lurking in the bottle.
• Other dishwashing soap brands I wouldn’t recommend are Ajax, Ivory, and Joy. Even their “Free & Clear” versions are guilty of greenwashing, still packing in SLES and artificial fragrances.

Types of Chemical-Free Dish Soap to Choose

Non-Toxic Dishwashing Liquid

Liquid dish soap is the go-to choice for most households, and for good reason. It’s easy to use, works on everything from greasy pans to delicate glassware, and is widely available. I mostly find myself using this type of soap because of its convenience and how easy it is to refill. The best non-toxic dishwashing liquids are made with plant-based surfactants, essential oils, and biodegradable ingredients, making them a safer alternative to conventional soaps filled with sulfates and artificial fragrances.

When shopping for safe dish soap, look for brands that are sulfate-free, phthalate-free, and EWG-verified to ensure you’re not coating your dishes in questionable chemicals. Bonus points if it comes in a recyclable or refillable bottle because sustainability matters, too!

Natural Solid Dish Soap Bars

If you’re looking to ditch plastic and make your dishwashing routine more sustainable, a solid dish soap bar is a fantastic alternative. These concentrated bars last two to three times longer than liquid soap and often come in zero-waste packaging. Plus, they’re usually free from water, which means no need for preservatives—just simple, effective cleaning power.

Most of the best natural dish soaps in bar form are made with coconut oil, olive oil, or castile soap, making them gentle on your hands while still tough on grease. To use, just rub a sponge, brush, or dishcloth directly onto the bar, and you’re ready to go. If you’re serious about reducing waste, a solid dish soap is the way to go!

Dishwashing Pods & Tablets

If you rely on a dishwasher to handle the dirty work, you’ll want to be extra picky about your dishwasher soap. Many conventional dishwashing pods and tablets contain harsh detergents, phosphates, and artificial fragrances, which can leave behind a toxic residue on your dishes and release chemicals into the water supply.

The best non-toxic dishwasher soap options are free from chlorine, phosphates, and synthetic fragrances, using plant-based enzymes and minerals instead. Some brands offer biodegradable pods wrapped in water-soluble film, while others come as loose powder or tablets. If you go this route, check for certifications like EPA Safer Choice or EWG Verified to ensure you’re getting a chemical-free dish soap that’s truly safe for you and the planet.

DIY Homemade Dish Soap

If you love a good DIY project and want complete control over your dish soap ingredients, making your own natural chemical-free dish soap is easier than you think. A basic recipe includes castile soap, baking soda, and essential oils, giving you an effective, non-toxic dishwashing liquid without any mystery ingredients.

Homemade soap won’t foam as much as commercial brands (because it’s free of sulfates), but don’t let that fool you—it still gets the job done. Plus, it’s cost-effective, waste-free, and can be customized to your scent preferences. Want a lemon-fresh clean? Add some lemon essential oil. Need an extra degreaser? A splash of vinegar can work wonders.

How We Tested & Rated These Nontoxic Dish Soaps

So, to separate the truly safe, non-toxic dishwashing liquids from the imposters, I conducted a detailed hands-on review. Each dish soap went through a rigorous evaluation process, testing ingredient safety, cleaning power, skin sensitivity, and environmental impact. Here’s how I did it:

Ingredient Safety Analysis

First things first—what’s inside the bottle? I cross-checked each soap against the Environmental Working Group (EWG) database, which ranks household products on a scale from A (safest) to F (most toxic).

I specifically flagged and eliminated any dish soap containing Sodium Lauryl Sulfate (SLS) & Sodium Laureth Sulfate (SLES), Phthalates & Synthetic Fragrances, Triclosan & Other Antibacterial Agents, Methylisothiazolinone & Benzisothiazolinone, Artificial Dyes & Colors Only chemical-free dish soaps with safe, biodegradable, plant-based ingredients made the cut.

Cleaning Power & Grease Removal

To test effectiveness, I put each soap through a real-life stress test:

• Oily pans & greasy dishes – I tested how well the soap cut through cooking oils, butter, and baked-on messes.
• Glassware & delicate dishes – I checked for streaking, cloudiness, or any residue left behind.
• Low vs. high lather soaps – Since most of the best natural dish soaps don’t foam as much as conventional ones (because they lack sulfates), I focused on actual cleaning power rather than just bubbles.

Some non-toxic dish soaps needed extra scrubbing, while others tackled grease effortlessly. Only those that performed consistently well across different dish types earned top ratings.

Skin Sensitivity & Residue Testing

Since dish soap directly touches your skin (unless you rock gloves every time), I tested how gentle each formula was on your hands. I hand-washed dishes with each soap for several days, noting any signs of:

• Dryness or irritation – Harsh soaps can strip skin’s natural oils, leading to dryness or redness.
• Sticky or filmy residue – Some soaps leave a thin, greasy film on dishes (yuck!), which can transfer to your food.
• Scent strength – I evaluated whether the scent was pleasant, overpowering, or too artificial.

The safest dishwashing liquid should clean well without irritating skin or leaving any residue behind.

Environmental Impact & Biodegradability

A natural chemical-free dish soap should be as kind to the planet as it is to your skin. I assessed each soap’s eco-friendliness by looking at:

• Biodegradability – Does the formula break down quickly and safely in water systems?
• Plastic waste – Does it come in recyclable, compostable, or refillable packaging?
• Certifications – Is it EPA Safer Choice, Leaping Bunny (cruelty-free), or Made Safe Certified?

Some soaps checked all the right boxes, while others—despite claiming to be “green”—contained hidden synthetic preservatives or came in excessive plastic packaging.

After testing each dish soap across ingredient safety, cleaning power, skin sensitivity, and sustainability, I assigned a final rating based on effectiveness and overall safety. Only the best non-toxic dish soaps made the top tier, while others fell short due to questionable ingredients, weak cleaning performance, or poor eco-credentials.

Final Thoughts on Non-Toxic Dishwashing Soaps in 2025

There you have it, my favorite dish soap without harmful chemicals in 2025 – all tested in my kitchen. While many brands market their products as “chemical-free” or “eco-friendly,” not all so-called non-toxic dish soaps are truly safe. A closer examination of ingredient lists often reveals hidden synthetic chemicals, including harsh surfactants, artificial fragrances, and preservatives that may contribute to skin irritation, environmental pollution, or even long-term health risks.

To ensure you are choosing a genuinely non-toxic dishwashing soap, it’s essential to go beyond marketing claims and carefully review ingredient labels. Look for plant-based surfactants, naturally derived fragrances, and biodegradable preservatives that are both effective and gentle on your skin and the environment. Avoid common irritants such as sodium lauryl sulfate (SLS), methylisothiazolinone (MIT), and artificial dyes, which have been linked to skin sensitivities and potential toxic effects.

Additionally, relying on third-party certifications from trusted organizations—such as ECOCERT, USDA Organic, or EWG Verified—can provide an extra layer of assurance regarding a product’s safety, sustainability, and ethical sourcing. These independent verifications help confirm that the chemical-free dish soap brands meet strict health and environmental standards, reinforcing their credibility.
