Best Non-Toxic Dishwasher Detergents (Without Alcohol Ethoxylates)

If you want a safe dishwasher detergent without the guesswork, here is where I land. The one I use is Pure Haven Liquid Dishwasher Detergent. I also rate Branch Basics Dishwasher Tablets, Blueland Dishwasher Tablets (Fragrance-Free), MamaSuds Automatic Dishwasher Powder, and Earthley Dishwasher Detergent Best, and I base that on their full ingredient lists rather than on green marketing.

Below, you’ll see why each product earns a Best, Better, or Not A Fan rating, and which “green” pods still fall short once you read the label.

What Ingredients Should I Avoid In Dishwasher Detergent?

I’d be on the lookout for the following ingredients:

• Methylisothiazolinone: a preservative I rate Not A Fan for its allergenic and sensitizing properties.
• Benzisothiazolinone: another preservative I rate Not A Fan for the same reasons.
• Fragrance: a blend of undisclosed chemicals that can include allergens, endocrine disruptors, and carcinogens.
• Ethoxylated ingredients (like alcohol ethoxylates and polyethylene glycol): may have trace residues of carcinogenic ethylene oxide used in the production process and a 1,4 dioxane contaminant.
• Cocamidopropyl betaine: a surfactant I rate Better (Not In My Top Picks) due to its allergenic and sensitizing properties and potential trace residues of carcinogenic nitrosamides.
• Polyvinyl alcohol (PVA): film coating on pods and packs that poses environmental concern.
• Acrylate polymers: agents that stop food and minerals from redepositing on your dishes as film or scale but have limited biodegradation.
• Colorants: add no cleaning power and only introduce an extra synthetic chemical that can leave residue on your dishes and rinse into waterways, so they are pure exposure with no benefit.

Why Avoid Alcohol Ethoxylates On Dishes?

Alcohol ethoxylates are ethoxylated surfactants, and they turn up in plenty of formulas marketed as “green” or “non-toxic.”

In 2023, Swiss researchers tested rinse aid on human gut cells and found that alcohol ethoxylates damaged the gut lining and triggered inflammation. They also found rinse-aid residue still on washed, ready-to-use dishware.

Even though the study looked at rinse aid rather than detergent tablets or pods, I avoid alcohol ethoxylates in detergents as a simple precaution. When that lining leaks, gut contents reach immune cells that normally never meet them.

Doctors recognize a damaged barrier in diagnosed diseases like celiac and inflammatory bowel disease. The bigger claim, that a leaky gut drives allergies and autoimmune conditions, remains a hypothesis. A 2021 review in Nature Reviews Immunology poses it as a question rather than settled science.

On a personal note, I once had a leaky gut and Hashimoto’s thyroiditis. I got better after many lifestyle changes, and switching detergents was part of it.

How Do I Pick A Dishwasher Detergent For My Water Hardness?

Water hardness is an important factor to take into consideration. It changes how well a detergent cleans (but it does not change how I rate a formula for safety):

• 0.3 gpg (grains per gallon) is soft water
• 3.5 to 7.0 gpg is moderate water
• 7 to 10.5 gpg is hard water
• over 10.5 gpg is very hard water

If you’re not sure, you can call your water district or use water hardness test strips.

Hard water is often the real reason a detergent leaves a film. As a rule of thumb, liquids and some tablets tend to hold up better in hard water, while some powders shine in soft water. That’s a cleaning tip, not a safety rating.

For safety, avoid fragrance, dyes, methylisothiazolinone, benzisothiazolinone, alcohol ethoxylates, and PVA coating. Glucoside surfactants in the formula are a good sign.

My Best Dishwasher Detergent Picks

These are the detergents I trust most because their formulations are clear from any ingredients of concern such as fragrance, dyes, methylisothiazolinone, benzisothiazolinone, alcohol ethoxylates, and PVA.

Pure Haven Liquid Dishwasher Detergent

I rate Pure Haven Liquid Dishwasher Detergent Best. It skips fragrance, Isothiazolinone preservatives, alcohol ethoxylates, and PVA film. It works well in hard and soft water. This is the dishwasher detergent I use. I also use other Pure Haven products, and you can see the full brand breakdown in my Pure Haven review.

Branch Basics Dishwasher Tablets

I rate Branch Basics Dishwasher Tablets Best. These plastic-free, fragrance-free tablets contain no alcohol ethoxylates, and they clean well in hard water. Enzymes, like protease and amylase, should not bother your lungs as they do not come in powder form.

Blueland Dishwasher Tablets (Fragrance-Free)

I rate Blueland Dishwasher Tablets (Fragrance-Free) Best. These fragrance-free tabs use no PVA film and no fragrance. Blueland does add fragrance or dyes to some other products, so I point you to the fragrance-free version only.  

MamaSuds Automatic Dishwasher Powder

I rate MamaSuds Automatic Dishwasher Powder Best. This is about as simple as mineral powder can get, with no enzymes, no fragrance, and no alcohol ethoxylates.

Earthley Dishwasher Detergent

I rate Earthley Dishwasher Detergent Best. The powder uses no fragrance or alcohol ethoxylates.

Dirty Labs Dishwasher Detergent and Booster

I rate Dirty Labs Dishwasher Detergent and Booster Free & Clear Best. The formula looks safe, without fragrance or alcohol ethoxylates.

Pronounce Dishwasher Detergent Powder

I rate Pronounce Dishwasher Detergent Powder Unscented Best. It is made without alcohol ethoxylates and fragrance. Be careful not to inhale its dust though because it uses enzymes and comes as powder.

My Better Dishwasher Detergent Picks

The dishwasher detergents that I rate Better have a clean detergent formula, but there’re a couple of things to keep in mind. For the pods, it’s the Polyvinyl Alcohol (PVA) film. While the film dissolves in the wash, research suggests a lot of PVA can still leave wastewater treatment and end up in the environment. For Biokleen powder, it’s an acrylic polymer that helps with spotting and film on dishes. But it’s a synthetic polymer that goes down the drain with every load. And for Nellie’s, it’s Cocamidopropyl Betaine that can cause allergy flares if you are sensitized to it as well as leave behind traces of carcinogenic nitrosamides. Overall, these dishwasher detergents are solid options if the mentioned trade-offs work for you.

AspenClean Dishwasher Pods

I rate AspenClean Dishwasher Pods Better because of PVA used to coat the pods that ends up in the environment.

Simple Truth Free & Clear Dishwasher Packs

I rate Simple Truth Free & Clear Dishwasher Packs Better because the packs are enveloped in PVA, an environmental pollutant.

Grove Co. Pure Power Dishwasher Packs Free & Clear

I rate Grove Co. Pure Power Dishwasher Packs Free & Clear Better. The packs are wrapped in PVA, a plastic polymer that contributes to environmental pollution.

Biokleen Free & Clear Automatic Dish Powder

I rate Biokleen Free & Clear Automatic Dish Powder Better because it contains an acrylic polymer. This ingredient helps prevent spots and film on dishes, but it’s a synthetic polymer that gets washed down the drain with every cycle.

Nellie’s Dishwasher Powder

I rate Nellie’s Dishwasher Powder Better because the formula contains Cocamidopropyl Betaine. I’m concerned about trace residues left on the dishes that can cause systemic contact dermatitis flares in those people who are sensitized to this ingredient. Plus, there may be traces of carcinogenic nitrosamides.

My Not A Fan Dishwasher Detergent Picks

The dishwasher detergents I rate Not A Fan still get dishes clean, but they include a few ingredients I’d rather leave out. The main one is ethoxylated ingredients, like alcohol ethoxylates. They work well as surfactants, but the process used to make them can leave behind traces of 1,4-dioxane, a contaminant that is reasonably anticipated to be a human carcinogen. Some of these picks also add fragrance with undisclosed ingredients. A few use dyes which add color but no cleaning power. And with the pods, the issue is the Polyvinyl Alcohol (PVA) film. It does dissolve during the wash, but much of that PVA can slip through wastewater treatment and still reach the environment. All in all, these detergents clean well, but the trade-offs are why they are not in my top picks.

Cascade Platinum Action Pacs

I rate Cascade Platinum ActionPacs Not A Fan. The formula includes ethoxylated ingredients, fragrances, dyes, and PVA film.

Seventh Generation Dishwasher Detergent Packs Free & Clear

I rate Seventh Generation Dishwasher Detergent Packs Free & Clear Not A Fan because of alcohol ethoxylates and PVA.

Cleancult Dishwasher Tablets

I rate Cleancult Dishwasher Tablets Not A Fan because they are made with an ethoxylated ingredient, fragrance, and PVA film.

Amway Home Automatic Dish Tablets

I rate Amway Home™ Automatic Dish Tablets Not A Fan due to the presence of alcohol ethoxylates and polyethylene glycol in the formula.

Finish Quantum Hard Water Tablets

I rate Finish Quantum® Hard Water Tablets Not A Fan. The ingredients include alcohol ethoxylates, fragrance, PVA, and colorants.

Frosch Lime Dishwasher Tabs

I rate Frosch Lime Dishwasher Tabs Not a Fan. First, the formula contains fragrance. Second, the ingredients are not fully disclosed, for example “non-ionic surfactants” and “water-soluble wrapping.” Since it’s a European product, EU detergent labeling law lets brands name broad classes of surfactants instead of every compound. Preservatives must still be named individually, so the gap here is in the surfactants and the wrapper. Those terms could well cover alcohol ethoxylates and polyvinyl alcohol (PVA).

Final Takeaway: Best Non-Toxic Dishwasher Detergents

Your dishwasher routine does not have to be stressful or expensive. Plenty of detergents clean well and still pass a careful label check, so you can start with a single swap and build from there.

I use Pure Haven Liquid Dishwasher Detergent every day, and when I want tablets, I reach for Branch Basics. Here are my Best picks one more time:

• Pure Haven Liquid Dishwasher Detergent
• Branch Basics Dishwasher Tablets
• Blueland Dishwasher Tablets (Fragrance-Free)
• MamaSuds Automatic Dishwasher Powder
• Earthley Dishwasher Detergent
• Dirty Labs Dishwasher Detergent and Booster (Fragrance-Free)
• Pronounce Dishwasher Detergent Powder

If you wash dishes by hand, my Non-Toxic Dishwashing Soap Guide covers that.

Frequently Asked Questions About Non-Toxic Dishwasher Detergents

What Is The Best Non-Toxic Dishwasher Detergent?

Pure Haven Liquid Dishwasher Detergent is my number one pick. Branch Basics Dishwasher Tablets and Blueland Fragrance-Free tablets are the tablet picks I trust.

Are Dishwasher Pods Non-Toxic?

Most pods use a Polyvinyl Alcohol (PVA) film I avoid. The inner formula can also hold synthetic fragrance or alcohol ethoxylates.

Do Non-Toxic Dishwasher Detergents Work In Hard Water?

Yes, non-toxic dishwasher detergents can work in hard water. In my experience, Pure Haven liquid, Branch Basics tablets, and Blueland Fragrance-Free tablets work in hard water.

Why Avoid Fragrance In Dishwasher Detergents?

Fragrance is an undisclosed blend of ingredients that I rate Not A Fan. Pure Haven uses lemongrass essential oil for scent, while Branch Basics and Blueland Fragrance-Free tabs use no scent at all.

What Should I Use Instead Of Conventional Dishwasher Detergent?

Look for a label with no fragrance, no Isothiazolinone preservatives, no alcohol ethoxylates, no dyes, and no PVA-coated pods. Treat glucoside surfactants as a good sign. Options like Pure Haven or Branch Basics fit those criteria once you read the full label.

Should I Avoid Rinse Aid?

If your rinse aid lists alcohol ethoxylates, and many do, it’s worth avoiding. The 2023 study points to rinse-aid residue as the main concern.
