Switching to an eco-friendly dish soap is one of the simplest changes you can make for the planet. Every time you wash dishes, soapy water flows straight down the drain and into waterways.
Conventional dish soaps are loaded with petroleum-based surfactants, synthetic fragrances, and harsh chemicals that harm aquatic ecosystems. Plant-based alternatives clean just as well without the environmental toll.
We’ve tested and researched the best eco-friendly dish soaps available in 2026. Here are our top picks for keeping your kitchen spotless while protecting the environment.

What Makes a Dish Soap Eco-Friendly?
Not all dish soaps labelled “natural” or “green” are truly eco-friendly. Terms like these aren’t regulated, so brands can use them loosely.
Look for plant-based surfactants derived from coconut, corn, or palm oil instead of petroleum. Avoid synthetic fragrances, which can contain hidden phthalates and parabens.
Third-party certifications are the most reliable way to verify a product’s green claims. Look for EPA Safer Choice, EWG VERIFIED, ECOCERT, or USDA Certified Biobased labels.
Biodegradable formulas that break down quickly in waterways are essential. Packaging matters too — choose brands using recycled plastic, refill systems, or plastic-free options.
1. Puracy Natural Dish Soap — Best Overall
Puracy has earned a reputation as one of the most trusted names in plant-based cleaning. Their dish soap is 99.41% natural and uses coconut-based cleansers that cut through grease effortlessly.
The formula is concentrated, so a little goes a long way. One bottle can handle up to 160 sinks of dishes, making it excellent value for money.
It’s PETA-Certified Vegan and Cruelty-Free, and the ingredients are gentle enough for sensitive skin. The Green Tea & Lime scent comes from essential oils rather than synthetic fragrance.
2. ECOS Dish Soap — Best for Sensitive Skin
ECOS has been making plant-based cleaners since 1967, and their dish soap is one of the most eco-conscious options on the market.
Every ECOS product is made in a carbon-neutral, water-neutral, TRUE Platinum Zero Waste certified factory powered by 100% renewable energy. That’s a sustainability track record few brands can match.
The coconut-derived surfactants tackle grease and baked-on food effectively, yet the hypoallergenic, pH-balanced formula is gentle enough for washing baby bottles.
It’s EPA Safer Choice Certified and completely free from dyes, parabens, phosphates, and 1,4-dioxane.
3. Seventh Generation Free & Clear — Best Fragrance-Free Option
If you prefer a dish soap with zero added scent, Seventh Generation’s Free & Clear formula is the gold standard.
It’s USDA Certified Biobased at 95% and carries the EPA Safer Choice seal. The plant-based formula powers through stuck-on food without leaving any residue or fragrance behind.
Seventh Generation has long been a pioneer in sustainable cleaning products. Their commitment to transparency means every ingredient is clearly listed and explained on the label.
This is an especially good choice for households with allergies, eczema, or chemical sensitivities.
4. Mrs. Meyer’s Clean Day — Best Scented Option
For those who love a beautifully scented kitchen, Mrs. Meyer’s Clean Day dish soap uses essential oils to deliver garden-inspired fragrances like Lemon Verbena, Basil, and Lavender.
The biodegradable formula is made without parabens, phthalates, or animal-derived ingredients. It’s cruelty-free and ECOLOGO certified.
Mrs. Meyer’s strikes a great balance between cleaning power and pleasant aromatics. The rich, sudsy lather cuts through grease while leaving your hands and kitchen smelling wonderful.
5. Truly Free Non-Toxic Dish Soap — Best Small Business Pick
Truly Free is a small, family-owned business that takes a no-compromise approach to clean ingredients. Their dish soap uses organic, plant-based ingredients and is free from over 4,000 harmful chemicals.
The concentrated formula comes in a refillable system designed to reduce plastic waste. You get a reusable bottle and concentrated refill pouches that mix with water at home.
It cuts through grease and dried-on food surprisingly well for such a gentle formula. The Sweet Basil scent is subtle and refreshing.
Tips for Making Your Dishwashing Routine More Sustainable
Choosing a plant-based soap is a great start, but there are more ways to reduce your kitchen’s environmental impact.
Use a compostable dish brush or loofah sponge instead of synthetic sponges that shed microplastics. Natural fibre brushes made from bamboo and sisal work beautifully and last for months.
Try using less soap than you think you need. Most eco-friendly dish soaps are concentrated, so a few drops are enough for a full sink of dishes.
If you hand wash, fill a basin rather than letting the tap run continuously. This simple habit can save thousands of litres of water per year.
Consider buying refill pouches or concentrates to cut down on plastic packaging. Many of the brands listed above offer refill options that use 80-90% less plastic than buying a new bottle.
The Bottom Line
Every dish soap on this list delivers genuine cleaning power without relying on harsh, planet-damaging chemicals. Whether you prioritise fragrance-free formulas, small-business values, or sustainability certifications, there’s an option here for you.
Our top overall pick is Puracy Natural Dish Soap for its outstanding plant-based formula, concentration, and value. But you really can’t go wrong with any of these five choices.
Making the switch to eco-friendly dish soap is a small change that adds up over time. Your waterways, your skin, and the planet will thank you.
