Anyone can print "non-toxic" on a label. We send our products to independent, accredited labs and publish exactly what comes back, in full.

How our testing works
Transparency should be something you can verify, not just something we say. So we send our finished products to independent labs, the kind accredited to recognized international testing standards, and we publish what they find. They are not us, and they have no stake in the result.
When a report says "none detected," it means the substance was below the level the lab's instruments can measure. That is not the same as a flat zero, and we would rather tell you what the science actually says than round it into a slogan. You will see the threshold on every result, so you know how sensitive the test was.
We test finished product, we publish the reports, and we retest as we go. This program is expanding across every product line, and each report names the lab that ran it, so this page will keep growing.
Independent and accredited
Tested by outside labs, not in-house.
Finished product
We test what ships, not just an ingredient list.
Published in full
Every report is here to download, with the lab named.
Liquid Laundry Detergent
We tested our unscented base formula, the same base every liquid laundry scent is built on. So these results cover the entire liquid laundry line.
Heavy metals
None detected
No detectable lead, arsenic, mercury, or cadmium.
Not detected above 0.001 ppm
Why we test: toxic metals build up in the body over time and can enter products as raw-material contaminants, not on purpose. They have no place in something that touches your skin and your water.
No detectable glyphosate (commonly known as the weed-killer Round-Up), or its byproduct AMPA.
Not detected above 0.01 ppm
Why we test: the most widely used herbicide in the world, and the subject of an active safety debate. Because our ingredients are plant-derived, we verify none carries through from sprayed crops.

All clear across a panel of more than 200 compounds.
200+ analytes, none detected above the lab's limits
Why we test: crop residues can carry through from the field into plant-based ingredients. We screen a broad panel so what is sprayed does not end up in your laundry.
No detectable 1,4-dioxane, the cancer-linked byproduct that can form when common surfactants are made.
Not detected above 1 ppm
Why we test: 1,4-dioxane is a manufacturing byproduct, not an ingredient, so it never appears on a label even when it is present. In 2024 the EPA determined it poses an unreasonable risk to human health, with concerns that include cancer, liver damage, and harm to the tissue involved in smell. It forms while the surfactants in many soaps and detergents are made, so a label cannot tell you whether it is there. A lab test can, so we run one.
No detectable phthalates across a panel of 9, including DEHP and DBP and the harder-to-catch DINP and DIDP.
Not detected above 10 ppm (100 ppm for DINP and DIDP)
Why we test: Phthalates are common plasticizers and fragrance carriers, and several are on California's Prop 65 list for reproductive concerns. They are rarely disclosed, so we screen the whole family.
Our bamboo paper line, screened for the contaminants that matter most in paper.
Heavy metals
None detected
No detectable lead, cadmium, or mercury.
Not detected above 0.002 mg/dm²
Why we test: paper touches your hands, your food, and your skin. Heavy metals can transfer from paper and accumulate in the body, so we confirm they are not there.
Why we test: forever chemicals that do not break down and build up in the body. They are common in grease- and water-resistant paper, so we test to confirm ours has none detectable.
We test as fast as we responsibly can. Independent lab testing is expensive and takes time, so we roll it out in waves, starting with the products you use most and the contaminants that matter most. We would rather test fewer things properly than put a badge on everything. We add results here as they come back, and every report names the lab that ran it.
Tell us what to test next
Is there an ingredient or a product you want screened? Tell us. The most-requested tests move up the list.
*None detected means below the lab's detection limit, which is not the same as a flat zero. ppm and mg per square decimeter are units of concentration. For scale, one drop of water in an Olympic pool is about 0.01 ppm.
Our commitment
We will keep testing, keep publishing, and keep adding to this page. If we test it, you will see it here, in full.
