Best Non-Toxic Dish Soap (and Is Dawn Toxic?)

“Non-toxic” on a dish soap is the maker's own word. What you can check is the maker's ingredient list and EPA's Safer Choice product list, so on October 18, 2026, we read both for Amazon's top dish soaps, Dawn included. Our pick, Seventh Generation Free & Clear, is on EPA's list by name, though it still uses isothiazolinone preservatives.

For the dishwasher, look elsewhere: Seventh Generation says “NOT FOR USE IN AUTOMATIC DISHWASHERS.” Our non-toxic dishwasher detergent guide covers machine detergents.

Is Dawn Dish Soap Toxic?

If you mean poisoning, Poison Control says “Drinking dish soap water or dish soap alone will usually result in minor effects.” It adds that dish soap “can cause nausea, vomiting, or diarrhea” if swallowed and “can cause eye irritation” if splashed in the eyes (Poison Control).

If you mean ingredients, read the lists. A Dawn Ultra Original refill jug was #1 in Amazon's Dish Soap best-sellers on October 18, 2026. Its Amazon ingredient list includes “COLORANTS”, “FRAGRANCES” and the preservative “METHYLISOTHIAZOLINONE”, and it ends with “Contains fragrance allergen(s).” Dawn Free & Clear drops the scent and color: Dawn says it is “crafted with 0% fragrance, dyes, phthalates, or chlorine added”. P&G's ingredient label for it still lists methylisothiazolinone and phenoxyethanol (P&G SmartLabel). No Dawn product was on EPA's Safer Choice list when we searched it on October 18, 2026.

Dawn's position: “The safety of the perfume, along with all other materials in our liquid dish soap, has been thoroughly assessed to ensure safe use as instructed.” On using Dawn as a hand soap, Dawn says it “is formulated to wash dishes, so if you suffer from dry or cracked skin or any redness, avoid using the product” (Dawn FAQ).

Are Dawn's Ingredients “Safer Choice Approved”?

You may see this in search answers. EPA's Safer Chemical Ingredients List does give a green circle to sodium lauryl sulfate, the first cleaner on Dawn Free & Clear's label. But that list rates single chemicals. EPA says it “includes many of the chemicals evaluated through the Safer Choice Program”. The Safer Choice label is for whole products, and for those “EPA reviews all chemical ingredients, regardless of their percentage in the product.” A green ingredient does not certify the bottle.

Who Certifies What: Safer Choice, EWG Verified, MADE SAFE

EPA Safer Choice is the U.S. government's label. “Every ingredient must meet strict safety criteria for both human health and the environment”. EPA also runs a fragrance-free label “to help consumers who prefer products without fragrance.” EPA adds: “Participation in the Safer Choice program is voluntary” (EPA). A bottle without the label may never have applied.

On October 18, 2026, EPA's product list held 54 home dish soaps. From our picks, only Seventh Generation's Free & Clear bottle and its refill were on it, both flagged fragrance-free. Dawn, Dapple, ATTITUDE, Dr. Bronner's and Meliora were not. Fragrance-free dish soaps on the list that we did not pick include Ultra Palmolive Pure + Clear Fragrance Free, ECOS Free & Clear and Biokleen Free & Clear (EPA Safer Choice products).

EWG Verified and MADE SAFE are private programs, not government ones. We report them as the maker's claim.

What Is in the Bottle: Each Maker's Own List

From each maker's own documents, for the exact bottle we link (Dawn Ultra Original, not a pick, is from its Amazon list). Swipe sideways on a phone.

One Brand, Four Ingredient Lists

Seventh Generation's product page and the 6-pack's Amazon listing both name benzisothiazolinone and methylisothiazolinone. Its safety data sheet (issued February 17, 2026) lists methylisothiazolinone and octylisothiazolinone instead, each at “<0.01%”, and no benzisothiazolinone (Seventh Generation SDS). The 6-pack's Amazon list also adds tetrasodium glutamate diacetate and sodium citrate. The data sheet adds propylene glycol (0.1% to 1%). The refill's Amazon list names caprylyl/myristyl glucoside where the bottle lists decyl glucoside. Formulas change, so read the label on the bottle you receive.

The Preservatives EPA Flags Yellow

Methylisothiazolinone (MIT), benzisothiazolinone (BIT) and octylisothiazolinone are allowed in Safer Choice products, but EPA codes all three with a yellow triangle: “The chemical has met Safer Choice Criteria for its functional ingredient-class, but has some hazard profile issues.” (EPA ingredient list). Among our picks, Seventh Generation uses two, Dawn Free & Clear uses MIT and Dapple uses BIT. ATTITUDE, Sal Suds and the Meliora bar list none.

What About 1,4-Dioxane?

EPA says “1,4-Dioxane may be found as a contaminant in consumer products such as soaps and detergents.” New York's limit for household cleansing products, dish soap included, has been 1 ppm since December 31, 2023, and the law allows waivers (NYSDEC). 1,4-Dioxane is not added on purpose; it can be left over from making some ingredients (EPA). FDA, writing about cosmetics, says those ingredients can be spotted by names such as “PEG” or the syllable “-eth-” (FDA). On our list, that means deceth-8 and C9-11 pareth-8 on Dawn Free & Clear's label (C9-11 alketh-8 on Ultra Original), plus the PEI-14 PEG-24/PPG-16 copolymer in both. That tells you where to look, not what is in a given bottle: none of the makers we read publishes a 1,4-dioxane figure.

Best Overall: Seventh Generation Free & Clear

The scented Seventh Generation that was Amazon's top unsponsored result for “non toxic dish soap” on October 18, 2026 adds “PLANT-DERIVED FRAGRANCES”; it has its own EPA entry, without the fragrance-free flag.

Fragrance-Free Dish Soap for Sensitive Skin and Baby Bottles

Three of our picks add no fragrance: Seventh Generation Free & Clear, Dapple and Dawn Free & Clear. Seventh Generation says Free & Clear is “made for your sensitive skin”. If your hands react, ATTITUDE gives this advice for its own soap: “If you have very sensitive skin, we recommend avoiding prolonged contact or wearing gloves.” Poison Control: “Some people have also reported having allergic reactions to dish soap.”

For Greasy Pans: Dr. Bronner's Sal Suds

Sal Suds is a concentrate, and Dr. Bronner's is clear that it “is not a soap but instead is a concentrated hard-surface all-purpose cleaner.” Its Amazon listing calls it a “heavy-duty nontoxic degreaser when used as directed for tough buildup”, and for dishes the maker's line is “One small squirt washes a sinkful.” For coated pans, see how to wash a nonstick pan.

No Plastic Bottle: A Solid Dish Soap Bar

A bar skips the plastic bottle. Meliora's care tip: “We recommend storing it in a draining soap dish.” If you would rather mix your own cleaner, our non-toxic kitchen cleaning guide covers castile soap and simple mixes.

How We Chose

We started with Amazon's results and Dish Soap best-sellers on October 18, 2026, with a U.S. address. We read each maker's ingredient pages and, where published, safety data sheets and California disclosures; searched every brand on EPA's product list; looked up key ingredients on EPA's ingredient list; and checked who sells each listing. Each drawback comes from the maker's words or EPA's codes. Some popular candidates are mentions, not picks: Mrs. Meyer's is scented, No Tox Life's dish block publishes no ingredient list we could find, ECOS Free & Clear (on EPA's list) was low on stock from Amazon, and Biokleen rated below our liquid picks on Amazon. Palmolive Pure + Clear is in the FAQ; we chose Seventh Generation because its line came first in Amazon's search. We did not test these dish soaps.
