Every Change diaper is made of fifteen thoughtfully chosen components. Everything that touches your baby is 100% cotton, and nestled inside is the world's first and only biodegradable Super Absorbent core. Below, you'll find every single component, what it's made from and how much of the diaper it makes up by weight.
There's no federal law that requires diaper brands to share a materials list, but we think you deserve to read ours the same way you'd read a food label, with every part listed in order alongside its share of the whole.
The short version
- Cotton: about a third of the diaper by weight. It is the top sheet against the skin, the leg cuffs, the front and back ears, and the outer cover. So the only thing touching your baby is 100% cotton.
- The absorbent core: about half of the diaper. Totally chlorine-free wood fluff pulp and the world's first and only biodegradable Super Absorbent core. Neither is made from crude oil.
- PLA: about a tenth. PLA is made from plant starch, not crude oil. We use it for the thin layers that hold the core together and for the closure.
- A bioplastic barrier film: a few percent, between the core and the cotton outer cover. It keeps wetness in and never touches your baby.
- Elastics and adhesives: about 2%. They are on the list because everything is.
Every component, top to bottom
Our table follows the diaper layer by layer, starting with the cotton that rests against your baby's skin and moving all the way out to the outer cover, then on to the little parts that fasten it and hold it all together. Each weight shows that part's share of a finished diaper, taken from our own materials list and rounded to one decimal. Two rows are still being confirmed, so we've marked them.
| Component | What it does | What it is made from | Share by weight |
|---|---|---|---|
| Top sheet | The layer against your baby's skin. Lets wetness pass through to the core. | 100% cotton, chlorine-free | 5.2% |
| Acquisition layer | Sits under the top sheet and spreads wetness across the core so it is absorbed faster. | PLA perforated film | 2.1% |
| Fluff pulp | The bulk of the core. Holds liquid and gives the diaper its softness. | Totally chlorine-free (TCF) cellulose fluff pulp | 25.2% |
| Super Absorbent core | Mixed through the pulp. It pulls wetness in and away from the skin. | The world's first and only biodegradable Super Absorbent core made from polysaccharide, not fossil fuel. | 25.2% |
| Core wrap | A thin layer above and below the core that holds the pulp and Super Absorbent in place. | PLA nonwoven | 3.8% |
| Leg cuffs | The soft barriers along each leg that stop leaks at the thigh. | 100% cotton, chlorine-free | 14.8% |
| Waistband | The band at the top that helps the diaper stay put. | PLA nonwoven | 1.8% |
| Elastics | The stretch inside the cuffs and waistband. | Spandex | 0.5% |
| Barrier film | Between the core and the outer cover. Keeps wetness inside the diaper. | MATER-BI bioplastic film | Being confirmed |
| Outer cover | The outside of the diaper, the layer you touch. | 100% cotton, chlorine-free | 14.6% |
| Wetness indicator | The stripe on the outside of the core that changes when the diaper is wet. Away from the skin. | pH-sensitive adhesive | Counted with adhesives |
| Front and back ears | The side panels the tabs fasten to. | 100% cotton | Being confirmed |
| Fastening tab and hook | The tab you pinch closed and the hook that grips the front panel. | PLA nonwoven tab, PLA film hook | 1.3% |
| Landing zone | The strip on the front panel the hook fastens to. | PLA nonwoven | 0.7% |
| Adhesives | Hold the layers together at sixteen points. | Formaldehyde-free hot-melt adhesive | 1.7% |
What touches your baby
Only four little parts ever touch your baby's skin while they're snuggled up in a Change diaper: the top sheet, the leg cuffs, the ears and the outer cover. All four are made of soft, 100% cotton, and the cotton is cleaned mechanically, not bleached.
Everything else stays tucked away inside the soft cotton: the acquisition layer, the core wrap, the barrier film and the waistband. Even the little elastic inside each leg cuff is wrapped up in cotton, so it never touches your baby.
What does the absorbing
The core is the absorbent heart of the diaper, making up about half of it by weight. Soft wood fluff pulp does most of the work, and it's Totally Chlorine Free, which means no chlorine compounds were ever used to whiten it. Mixed all through that pulp is the world's first and only biodegradable Super Absorbent core, which pulls wetness in and away from your baby's skin, and it isn't made from fossil fuels. A certified third-party lab has independently tested it to biodegrade, and we'll be sharing the lab summary right here on our site so you can see it for yourself.
Conventional disposables use a superabsorbent made from sodium polyacrylate, which is made from acrylic acid derived from petroleum. If you are reading another brand's list, that is the line to look for. Our guide to reading a diaper materials list explains what each line means.
Made with biodegradable components
Every Change Diaper is made with biodegradable components, and we love being able to show you exactly what that means. Our Super Absorbent core has been independently tested by a certified third-party lab to biodegrade, our cotton is borrowed from nature, and our PLA parts are made from plant starch. The elastics and hot-melt adhesive are the pieces we're working to improve and replace. We'll be sure to update this page as soon as that changes.
What is not in it
No fragrance. No lotion. No chlorine bleach on the cotton or the pulp. No fossil-fuel plastic against the skin. No sodium polyacrylate. No BPAs. No phthalates.
How to compare to other diapers
- Ask which layer a material claim describes. "Cotton" on the front of a box can mean a cotton top sheet over plastic. Ours is cotton on every layer that can touch your baby.
- Ask what the superabsorbent is made from. Ours is the world's first and only biodegradable Super Absorbent core. Everything else on the market uses sodium polyacrylate.
- Ask for the share by weight. A list without weights cannot tell you whether cotton is a third of the diaper or a thin liner. Ours is here, component by component.
See sizes and buying options, check the fit guide, or read the FAQ for fit and subscription questions. If you need a detail that is not on this page, ask us and we will answer with the sheet in front of us.
