The Toxome Chrome Extension
Check clothes for toxic chemicals, while you shop.
A free Chrome extension that reads the fiber composition on any product page, rates the garment out of 100, and tells you what those materials do to your body. You see it before you add to cart, instead of after it arrives.
One email when it launches. No spam. See our privacy policy.
What it catches
The things a brand would rather you skimmed.
Plastic fibers
Polyester, nylon, acrylic, and elastane are plastics. They trap heat and sweat against your skin, and they shed microplastics every wash. The extension names them by percentage instead of letting them hide behind the word 'blend'.
PFAS and finishes
Stain-resistant, wrinkle-free, and water-repellent finishes are the ones most likely to carry PFAS. Toxome flags the language a brand uses to describe them.
Formaldehyde and dyes
Wrinkle-resistant cotton is often treated with formaldehyde resin, and disperse dyes on synthetics are a common cause of contact dermatitis. Both get called out in the score.
The vague ones
'Viscose', 'bamboo', and 'plant-based' cover a wide range, from a closed-loop lyocell to a generic viscose with a dirty process. Toxome grades the fiber you got.

Everything worth knowing, before “add to cart.”
A rating, not a guess
The same wearer-health rubric as the Toxome app, scored out of 100 with a plain verdict: great, good, okay, or bad. How we score
The full composition
Every fiber by percentage, pulled straight from the label, even the fine print tucked inside collapsed accordions.
Why this score
Plain English, never jargon. Polyester is a plastic fiber; elastane is occlusive and disperse-dyed. You see what each material does to your body.
Save it for later
Add a piece to your Wishlist while you decide, or to your Closet once it's yours. Your closet score follows you across the web and the app.
Questions
The extension, answered.
It reads the fiber composition on any clothing product page and shows you a health rating out of 100, the full material breakdown by percentage, and a plain-English explanation of what those materials do to your body. It appears on the product page automatically, before you add anything to cart.
Start with the composition label. The fiber is most of the story. Plastic fibers like polyester, nylon, acrylic, and elastane shed microplastics and trap sweat. Performance finishes like stain-resistant, wrinkle-free, and water-repellent are the ones most likely to carry PFAS. Wrinkle-resistant cotton is often treated with formaldehyde resin. The Toxome extension does this read for you on the page, and the Toxome app does it from a photo of a physical label.
Any clothing product page on the web. It isn't a list of partner retailers, it reads the composition wherever the brand publishes it, including the fine print inside collapsed accordions and tabs.
Yes. Installing it and seeing the rating, the composition, and the reasoning costs nothing.
On the same wearer-health rubric the Toxome app uses. It scores what the garment does to the person wearing it, starting from the fiber and then applying penalties for the chemistry a fiber usually brings with it. Read the full method.
No. It looks at the clothing product page you're on to read the composition, and that's all. It isn't building a profile of where you shop.
Not yet. It's launching on Chrome first. If you want it somewhere else, get on the list and tell us where.
No, they do different jobs. The extension checks clothes you're about to buy online. The app checks clothes you already own, by scanning the physical label. They share one Closet, so a piece saved in either place shows up in both.
In the meantime
Start with what's already in your closet.
The Toxome app does the same thing for the clothes you already own. Scan a label, get the rating, and see what your wardrobe is made of.
