11 Best Non-Toxic Dish Soaps for 2026 (Liquid, Powder & Bars)

Raise your hand if you love washing dishes. Anyone? At least with non-toxic dish soap, the dreaded task of cleaning last night’s stir-fry isn’t also causing damage to marine life, waterways, and your health.

Why this matters? Conventional dish soaps often contain undisclosed toxic chemicals like phosphates, synthetic fragrances, and hormone disruptors that can harm your health and contaminate waterways. At the federal level in the US, manufacturers aren’t required to list these ingredients, making it difficult to know what you’re bringing into your home.

What is non-toxic dish soap? Non-toxic dish soaps use biodegradable, plant-based formulas free from harmful compounds like synthetic fragrances, preservatives, phosphates, triclosan, and synthetic surfactants. We’ve included a range of safer dish soap options in liquid, powder, and bar formats that are just as effective as conventional brands (we’ve tested and rated many of them ourselves).

For this list, we’ve prioritized safe ingredients (with certifications from EWG, MADE SAFE, EPA Safer Choice, and Leaping Bunny), sustainable packaging (plastic-free and refillable options), and proven effectiveness.

How We Test Dish Soaps

We test dish soaps in our own homes over several months of regular use. Our team evaluates each product on:

• Performance: Does it cut through grease and clean effectively?
• Longevity: How long does one bar, bottle, or refill last with daily use?
• Convenience: Is it easy to use and store?
• Sustainability: Does the brand’s sustainability performance match their claims (e.g., is the packaging actually plastic-free when it arrives)?

Products we’ve personally tested are noted in the reviews below with specific details about our experience.

Note: We now conduct comprehensive sustainability assessments for brands using 22 different criteria including chemical use, customer safety, product performance, and transparency. Rated brands have been through one of these assessments (look for the rating badge on the list below). Find other rated brands in our sustainable brand directory.

Unfortunately, the array of colorful, fragrant kitchen supplies we’ve become accustomed to can contain toxic ingredients that can significantly impact your health and the environment.

Where dish soaps are concerned, this means grease-destroying enzymes, bleaching agents, surfactants, preservatives, and other harsh chemicals. These compounds enter our waterways and affect human health, with some linked to allergic reactions, skin irritation, or even cancer.

And regulation is not quite there in terms of keeping folks safe. At the federal level in the US, dishwashing detergents and other household cleaning products regulated by the Federal Trade Commission are still not required by law to list their ingredients. However, California and New York now mandate ingredient disclosure, and many manufacturers have adopted voluntary ingredient transparency practices. Despite these improvements, consumers in most states still have no federal guarantee of full ingredient disclosure on cleaning products.

So even though we think we’re getting our dirty dishes clean with dish soap, non-toxic ingredients are the only way to ensure they actually are.

If most conventional dish soaps contain harmful ingredients that aren’t listed on the label, how do you know what’s actually safe? Here’s what to look for when choosing non-toxic dish soap:

Look for third-party certifications
Independent certifications verify that products meet strict safety standards. Key certifications to look for include:

• EWG Verified – Ingredients screened for health concerns
• MADE SAFE – Comprehensive non-toxic certification
• EPA Safer Choice – Meets EPA’s strict ingredient safety standards
• Leaping Bunny – Cruelty-free verification
• USDA BioPreferred or Certified Biobased – Contains renewable plant-based ingredients
• B Corp – Meets high social and environmental standards

Check the ingredient list

Non-toxic dish soaps use plant-based, biodegradable formulas. Avoid these common harmful ingredients:

• Phosphates: Phosphates get into waterways, leading to mineral poisoning and harming aquatic ecosystems and marine life.
• Polyacrylates: This chemical is toxic to marine animals and can cause critical burns and eye damage to humans.
• Benzisothiazolinone: This is a pollutant to marine life and can cause lung, skin, and eye irritation and bronchitis in individuals.
• Methylisothiazolinone: Many individuals are allergic to this compound, causing allergic reactions and, in some cases, neurotoxicity.
• Synthetic Fragrances: The nice scents of traditional dish soaps have countless undisclosed compounds, leading to allergic reactions, rashes, and harm to the environment.
• Dyes: Dyes don’t serve a purpose and may cause rashes and allergic reactions. Many dyes used in dish liquid have been linked as endocrine disruptors and carcinogens.
• Bleach: Bleach damages the eyes and skin. It can also lead to gastric issues, throat damage, and fluid build-up in the lungs.
• Surfactants: Surfactants are typically sourced from palm oil, petroleum, or animals in regular liquid soap.

Instead, look for natural dish soap formulas made with coconut-derived surfactants, essential oils for scent, and organic plant-based ingredients.

Use comprehensive brand ratings
We conduct in-depth sustainability assessments for brands using 22 criteria across four categories: Nature & Animals, Communities & Wellbeing, Values & Governance, and Product Performance. Brands that score in the top 10% earn a “Disrupting” rating. Look for rated brands throughout this guide (they’ll have a rating badge) – these brands have been thoroughly vetted beyond just their marketing claims. Learn more about our ratings.

Consider packaging and refill options

The best dish soaps come with limited exposure to plastic:

• Refillable containers – Glass or aluminum bottles with refill pouches or take-back programs
• Plastic-free bars – Ultra-concentrated solid soap that lasts months
• Powder formats – Waterless options that reduce shipping emissions
• Compostable packaging – Like beeswax pods or paper wrapping

At minimum, recyclable packaging made from post-consumer recycled materials

Choose the right format for your needs

• Liquid concentrate – Traditional feel, works in dish water, often refillable
• Powder – Waterless, long-lasting, minimal packaging, travel-friendly
• Bar soap – Longest lasting (replaces 3+ bottles), zero packaging, budget-friendly

Verify cruelty-free and vegan claims
We reject products tested on animals at any stage. Look for Leaping Bunny certification for verified cruelty-free products. For vegan options, avoid animal-derived surfactants and ingredients (some brands use beeswax for packaging, which may be acceptable depending on your preferences).

Prioritize palm oil-free or RSPO-certified
Palm oil production drives deforestation. Choose brands that are palm oil-free or, at minimum, use Roundtable on Sustainable Palm Oil (RSPO) certified palm oil.

Support ethical sourcing and transparency
The best brands disclose their full ingredient lists, publish sustainability reports, and source ingredients ethically with fair labor practices throughout their supply chain.

Non-Toxic vs. Natural Dish Soap: What’s the Difference?

The terms “non-toxic” and “natural” are often used interchangeably, but they’re not necessarily the same thing.

Natural dish soap means the product is made from naturally derived ingredients like plant oils, minerals, or botanical extracts. However, “natural” isn’t regulated, so brands can use this term even if their formula contains some synthetic ingredients or hasn’t been tested for safety.

Non-toxic dish soap means the product has been verified to be free from ingredients known or suspected to harm human health or the environment. Non-toxic products are evaluated based on scientific safety data, not just ingredient origin.

This means dish soap can be natural but not entirely non-toxic (if it contains natural allergens or irritants), and a product can be non-toxic but not 100% natural (if it uses safe synthetic ingredients).

What to look for: The safest dish soaps are both natural and non-toxic. Look for plant-based formulas with third-party certifications like EWG Verified, MADE SAFE, or EPA Safer Choice – these verify that ingredients are both naturally derived and scientifically proven safe.

Is non-toxic dish soap as effective as regular dish soap?

Yes, non-toxic dish soap is just as effective at cutting grease and cleaning dishes as conventional brands. Plant-based surfactants (like those derived from coconut oil) work the same way as synthetic surfactants to break down grease and food residue. Many non-toxic options are actually concentrated formulas, meaning you use less product per wash. In our testing, brands like Blueland, No Tox Life, and Meliora performed just as well as conventional dish soaps without the harmful ingredients.

What ingredients should I avoid in dish soap?

Avoid phosphates (toxic to aquatic ecosystems), synthetic fragrances (undisclosed chemicals, allergens), sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), triclosan (antimicrobial that contaminates waterways), parabens and phthalates (hormone disruptors), synthetic dyes (unnecessary irritants), formaldehyde and formaldehyde-releasing preservatives, chlorine bleach and ammonia.

Look for plant-based, biodegradable formulas with full ingredient disclosure instead.

How long does a dish soap bar last?

A dish soap bar typically lasts 3-5 months with regular use, replacing 3 or more bottles of liquid dish soap. The exact lifespan depends on how frequently you wash dishes and how you store the bar. To maximize longevity, keep the bar in a well-drained soap dish between uses to prevent it from becoming soggy. In our testing, No Tox Life’s dish block lasted nearly 5 months with daily dishwashing.

Can I make my own non-toxic dish soap?

Yes, you can make homemade dish soap using simple ingredients like castile soap (Dr. Bronner’s works well), water, and optional additions like washing soda or essential oils. However, DIY dish soap can be less effective than commercial formulas and may require experimenting with ratios. For most people, buying concentrated or refillable non-toxic dish soap from verified brands is more convenient and ensures consistent performance. If you do make your own, avoid recipes that use only baking soda or vinegar, as these don’t effectively cut grease.

Is Dawn dish soap non-toxic?

No, most Dawn dish soaps are not non-toxic. According to EWG’s ratings, only 3 out of 17 Dawn products scored above a B grade, with over 50% receiving a D rating. Many Dawn formulas contain methylisothiazolinone (a known allergen), synthetic fragrances, harmful dyes, and surfactants like SLS or SLES. These ingredients can damage the nervous system, respiratory system, and organs, cause skin irritation and allergies, and harm aquatic ecosystems. The non-toxic dish soaps on our list offer safer alternatives without these harmful compounds.

Are non-toxic dish soaps safe for septic systems?

Yes, non-toxic dish soaps are generally safe for septic systems because they use biodegradable, plant-based ingredients that break down naturally. Unlike conventional dish soaps that contain phosphates and synthetic chemicals that can disrupt septic bacteria, non-toxic formulas won’t harm the beneficial bacteria needed for proper septic function. Though, you should always look for products specifically labeled as septic-safe or biodegradable if you have a septic system.

What’s the difference between dish soap and dishwasher detergent?

Dish soap (for handwashing) creates suds and is designed for manual scrubbing with a sponge or brush. Dishwasher detergent is formulated specifically for automatic dishwashers and is low-sudsing to prevent overflow and damage to the machine. Never use regular dish soap in a dishwasher, as the excessive suds can cause leaks and malfunctions. For non-toxic dishwasher detergent options, check out our guide to eco-friendly dishwasher detergent or our DIY guide to dishwasher detergent.

Do non-toxic dish soaps work in hard water?

Non-toxic dish soaps can work in hard water, though some formulas perform better than others. Plant-based surfactants may not lather as much in hard water compared to synthetic options, but they still clean effectively. For best results in hard water, use slightly more product or choose powder or bar formulas, which tend to perform better than liquids. Brands like Blueland and Meliora have formulas that work well in various water conditions.

Are non-toxic dish soaps more expensive?

Non-toxic dish soaps have a higher upfront cost but often provide better value long-term. Concentrated formulas mean you use less per wash, bar soaps last 3-5 months (replacing multiple bottles), and powder formats eliminate water weight in shipping. When you factor in longevity and refill programs that reduce packaging costs, many non-toxic options are comparable or cheaper than buying conventional dish soap repeatedly. Entry-level options start around $8-12, while premium concentrated formulas range from $12-20.

Can non-toxic dish soap be used for other cleaning tasks?

Yes, many non-toxic dish soaps are versatile enough for multiple cleaning tasks. Castile soap-based options like Dr. Bronner’s can be diluted for cleaning counters, floors, and bathrooms. However, dish-specific formulas are optimized for grease-cutting on dishes. For multi-purpose cleaning, choose products explicitly marketed as versatile (Dr. Bronner’s claims 18 uses) or check with the manufacturer about recommended uses beyond dishwashing.

Final Thoughts On The Best Clean Dish Soap Brands

It’s easy to forget about health and safety with a sink full of dirty dishes waiting for you after work. But the supplies we use to clean our dishes, kitchen, and hands have a greater impact on the ecosystem and personal health than you might think. Conventional dish liquids can contain harmful ingredients affecting the waterways and health, causing irritation, allergic reactions, and severe health consequences.

That’s why switching to safer dish soap or dishwashing liquid is a must. These products will help keep your home free of harmful chemicals.
