The only diaper in the world with no monomer residue.
Every other diaper's Super AbsorbentSuper Absorbent: the core inside every disposable diaper. It pulls wetness in and away from your baby's skin. Most brands make theirs from crude oil, and it leaves a monomer residue behind. Ours is Mono-Free™: made from polysaccharides, not fossil fuel, tested by SGS to have zero monomer residue, and the world's first and only biodegradable Super Absorbent core. How our core works starts with crude oil and leaves behind a monomer, a known skin irritant, right next to your baby's skin. Ours is Mono-Free™, made from polysaccharides, not fossil fuel. And only 100% cotton touches your baby.

The disposable arrives.
Built on fossil-fuel plastic from day one. Convenience won.

The crude-oil core.
Petroleum Super Absorbent becomes the standard. So does the monomer residue it leaves behind.
-
1990s
Rash becomes "normal."
Sealed plastic runs hot and humid once it's wet. Diaper rash gets accepted as a fact of babyhood instead of a design flaw.

The "plant-based" wave.
Bamboo and "eco" diapers arrive. Underneath, still fossil-fuel plastic, still the same crude-oil core.

The first Mono‑Free™ diaper.
Only 100% cotton touches your baby, with the world's first and only biodegradable Super Absorbent core.
Monomer is in every diaper's core. Except ours.
MonomerMonomer: the leftover chemical from making a petroleum super absorbent. It is made by linking acrylic acid into long chains, and the linking is never complete, so a little acrylic acid is always left in the finished material. The CDC lists acrylic acid as a skin irritant.Read the CDC page is a chemical left behind when a diaper's absorbent coreSuper Absorbent: the absorbent core inside every disposable diaper. It pulls wetness in and away from your baby's skin. Conventional diaper brands use a Super Absorbent Polymer made from crude oil. Ours isn't a polymer at all: it's the world's first biobased, petroleum-free, super absorbent, and it's biodegradable too.How our core works is made from petroleum. The CDC lists it as a skin irritant. That core sits very close to your baby's skin for hours, every day.
Every diaper has a little re-wetRe-wet: when your baby sits or rolls over, a little of the pee the core is holding gets pressed back up toward the skin. Every diaper does it, ours included. On the standard re-wet test, Change performs as well as any diaper on the market., so what's in the core matters. Change is the only diaper in the world with no monomer residue, tested by SGSSGS: an independent, third-party testing lab. They tested our Mono-Free™ core for residual monomer and found none.. With 100% cotton as the only thing touching your baby, it's a diaper built to help prevent diaper rash.
Soft as cotton. Tough as any diaper.
Every diaper is judged on the same two industry lab tests. Change performs as well as any diaper on the market.
- Strike-through
- How fast wetness soaks in.
- Matches the best
- Re-wet
- How much comes back out when it's pressed.

“I've been very impressed with Change diapers. The diaper is thick in a way that feels durable and high quality. They absorb well and we haven't had an issues with leaks, including during overnight use. I also appreciate that they are an environmentally friendly option. Would definitely recommend!”
Sarah D. -
“I've never seen diapers made like this. As a mom of almost 4, I've used and felt a lot of diapers. Change diapers legitimately feel like they are made of a premium fabric. I've never been so impressed with a diaper as a mom.”

“i love these diapers! the texture at first threw me off because it's different than a traditional diaper, you expect soft and fluffy and this was more stiff but i pinched it and fluffed it. my daughter liked it and the absorption was great! my daughter sleeps through the night and she doesn't leak at all by morning! they are true to size as well!”

“I have been searching for a diaper to replace our previous favorite which sadly changed, and this is it! Just got my small pack delivered and will absolutely be ordering more. Quality construction, soft, durable, and no funky smells. My baby is chunky and they fit him well. So happy with these diapers!”
Nicole -
“I've always been really picky about diapers and have switched brands based on how my kids' skin reacts. I've been using Change since their recent launch and have been so happy with them. No diaper rashes, incredibly soft, and the performance has been great!”
