Your baby’s safety is our priority. Pampers carefully selects each ingredient using trusted science and technology. Our diapers are thoughtfully designed with carefully selected materials to ensure your baby's comfort, dryness, and safety.
We back our promise with a rigorous multi-step safety process that includes thousands of tests—from ingredients to daily quality checks. We’re committed to openness—here’s a breakdown of what makes up our diapers:
Topsheet
The soft topsheet, which touches your baby's skin, uses Polypropylene and Polyethylene for absorption. These common materials have a long history of safe use in diapers and fabrics, helping to keep your baby comfortable and dry. Our diapers also include an Emollient/Balm for skin comfort, a cosmetic ingredient added to the topsheet to help maintain healthy skin.
Core
The diaper's core is designed for maximum absorption. It features Polyester, a common and safe fabric material, to help keep your baby comfortable and dry. We also use Cellulose (wood fibers) which soaks up liquid. These fibers are purified using an elemental chlorine-free process and come from FSC®-certified forests and other controlled sources. To quickly lock away wetness, the core contains Sodium polyacrylate, a superabsorbent material that keeps baby's skin comfortable and dry and is safe for use in diapers.
Cuffs
The cuffs around the legs are designed for comfort and protection. Made with Polypropylene, a common and safe material, they offer softness, durability, and protection. Elastane/Spandex provides a stretchy, latex-free material for a snug fit around the legs. For a touch of charm, Pigments are used for aesthetics, offering safe, skin-friendly colors.
Fastening System
Our fastening system securely holds the diaper in place. Both Polypropylene and Polyethylene are used here for fastening. These common and safe materials deliver comfort and breathability, ensuring the diaper stays comfortably on your baby's belly.
Outercover
The outercover is designed for breathability and protection. It uses both Polyethylene and Polypropylene, common and safe materials known for delivering softness, breathability, and overall protection. For delightful designs, Pigments are added for aesthetics, providing safe, skin-friendly colors. These pigments are used in tiny amounts and are positioned away from your baby's skin.
Wetness Indicator
A helpful water-soluble colorant acts as the urine indicator. This pH-sensitive material changes color when wet with urine, clearly signaling that it's time for a diaper change. Importantly, this wetness indicator does not come into contact with your baby's skin.
Adhesives
To keep all the diaper layers securely together, we use Polymers as adhesives. These adhesives are carefully placed underneath the diaper layers, ensuring they do not touch your baby's skin.

"Overwhelming frangrance!!!"
Catherine
“I am sad because these do work well for my baby. But my husband and I can not get past the reeking overwhelming fragrance on these overnight diapers. We co-sleep and I am not joking when I say the frangrance on the diapers is incredibly strong. It is so strong that if I even move our blanket the soapy perfumy scent overwhelms us. It actually makes it hard to sleep. And once we change her diaper in the early morning to a regular pamper swaddlers the smell lingers on her clothes. I don’t know if they just seriously messed up with this batch( just switched to size 4 from size 3) or what?! I am worried that that amount of fragrance can not be good for her little respiratory system so we have to stop using them,. And having paid for a big box, that really sucks. Pampers please lessen the fragrance or offer a frangrance free option. We love your diapers but these overnight ones are horrendous.”
Response from Pampers
We’re very sorry about your experience, Catherine, especially since Pampers Swaddlers Overnights have been fragrance-free since December 2025. It's possible your pack could be from before that change, or that it could have been stored near something highly scented, and absorbed the fragrance. We understand this is upsetting, because safety is our top priority. All Pampers products are thoroughly evaluated to be safe when used as directed and this isn’t what we would expect. Please contact us at 1 (800) 726-7377 for more help.
"Don’t waste your money"
Staci S
“Pampers zzz did not live up to the hype. Baby wakes up wet after a few hours. At first I thought it was me, maybe I was putting the diaper on too loose etc, but after a week of using and baby soaking through them I knew it was the diaper. If anyone has suggestions on a better diaper please let me know, just want my little to be comfortable!”
Response from Pampers
Staci, we know how important it is to keep your baby comfortable and dry, and are sorry they experienced nighttime leaks. While a proper fit is important, sometimes babies can outgrow the absorbency of a diaper before the size, so trying a larger size can help. We'd like to help further, so when you have a moment, please call us at (800) 726-7377.
"Mrs Lasiter"
Lisa
“We have always been pleased with the superior and superb quality of pampers products. We started our sweet little nugget out in swaddlers and have graduated to the 360 ones to accommodate our busy 20 month old. We switched to the overnights for bedtime when we noticed our son’s sleep sack was wet with pee pee a few mornings. Since we switched to the overnights we have had all dry ones in the AM starting the day off just right!!!! They do tend to be a little bit more expensive than some of the other brands but you get what you pay for with pampers!!! A good quality product is soo worth it when dealing with your precious offspring!!! They also have an amazing rewards program that helps you pay for all your pamper products in future.”
"Disappointed"
Monica
“I was hoping this would make a big difference for when my son sleeps. Every morning he still wakes up wet. I’ve had to put a pad under him to not get bedding wet.”
Response from Pampers
Monica, we know that a leaky diaper is the last thing you and your baby want to wake up to, and are sorry this has been your experience. Size and fit are a huge part of finding the right diaper for your baby. It's important to know that frequent night-time leaking can be a sign that a larger diaper size might suit your little one better for overnight. So we can help you find the right diaper for your baby, please call us at (800) 726-7377.
"Definitely good experience"
