Dirty Labs
Quick verdict: Most non-toxic detergents ask you to accept a slightly worse wash. Dirty Labs doesn’t, and that’s the whole reason it’s here. It was built by a chemist around an enzyme complex rather than by swapping harsh cleansing agents for gentler ones, and on real stains it outperforms most of what’s in this directory. It’s also concentrated enough that a small bottle lasts. What it lacks is certification. Our rating: 3.9 out of 5.
Who they are
Dr. Pete He, a chemist who previously worked with The Sustainability Consortium, and David Watkins, a product designer, founded Dirty Labs in 2018. The technical premise is unusual for the category: rather than reformulating around a restricted list, they engineered an enzyme system to do the cleaning work that aggressive detergents normally handle.
It’s independent and founder-led, based in Portland.
What they get right
It cleans better than the category norm. Enzymes break down protein, starch and fat stains at low temperatures, which is precisely where plant-based detergents usually fail. If you’ve abandoned a natural detergent because of a stain it wouldn’t lift, this is the one to try.
It’s highly concentrated. A small bottle covers a lot of loads, which cuts both shipping weight and per-load cost.
Cold-water performance is a real environmental gain rather than a marketing angle. Heating water is most of a wash’s energy footprint, and an enzyme system that works cold lets you drop the temperature without dropping results.
Packaging is amber glass and aluminum rather than plastic, with refills.
Full ingredient disclosure, in a category where “fragrance” legally hides dozens of undisclosed inputs.
Where they fall short
Certification is the gap, and it’s why this sits below 4.0. Leaping Bunny covers animal testing. There’s no MADE SAFE, no EPA Safer Choice, no EWG Verification, and no B Corp. The brand’s own site doesn’t claim one. Against Blueland’s six certifications or Meliora’s MADE SAFE, you’re trusting a well-credentialed founder rather than an auditor, and our own greenwashing guide says to check exactly this.
It’s also priced above the cheap end. Per load it’s reasonable given the concentration, but the sticker is higher than Meliora or Dropps.
The glass bottle is heavy and breakable, which is a real consideration in a laundry room.
Enzymes also aren’t for everything: they’re less effective on mineral stains and rust than on organic ones.
What they sell and what it costs
Laundry detergent, dishwasher detergent, an oxygen booster and scent boosters. A bottle typically runs $20 to $30 and covers a large number of loads, so per-load cost lands mid-range.
Who it’s actually for
Anyone who tried non-toxic detergent, found the wash disappointing, and went back to conventional. It’s also the strongest pick if you wash cold and want that to actually work.
If certification is what convinces you, Meliora or Blueland. If you want the cheapest, Meliora.

Frequently asked questions
Does Dirty Labs actually clean better than other natural detergents?
In our reading of the category, yes, and the mechanism explains why. Enzymes break down the specific molecules that make up protein, starch and grease stains, which is a different approach from using stronger detergents to strip everything indiscriminately. It’s the detergent we’d point at if a natural formula has disappointed you before.
Is Dirty Labs certified?
Only Leaping Bunny, for animal testing. There’s no MADE SAFE, EPA Safer Choice, EWG Verification or B Corp, and the company doesn’t claim any. The ingredient list is fully disclosed and the founding chemist’s background is real, but that’s a track record rather than an audit, and it’s the reason this scores below the certified alternatives.
Does it work in cold water?
Yes, and that’s one of its better arguments. Enzymes are active at low temperatures, so you can wash cold without the drop in results that usually pushes people back to warm cycles. Heating water is most of a wash’s energy use, so it’s a real saving.
Is it worth the price?
Per load, it’s competitive, because the formula is concentrated enough that you use very little. The up-front bottle price is higher than the budget options. If cleaning performance is what’s been stopping you switching, it’s the one worth paying for.
