Absorbent Materials in Nappies: Keeping Your Baby Dry

Understanding how absorbent materials in nappies work can help explain how modern nappies keep babies dry and comfortable throughout the day and night. Our Pampers nappies are designed with multiple layers that work together to quickly absorb and lock away moisture to protect delicate skin from wetness.

Our materials are carefully selected to provide absorbency, softness and flexibility, so our nappies remain comfortable and dry without feeling bulky.

In the sections below, we’ll explore how absorbent materials in our nappies function, the key components involved, and why absorbency plays an important role in your baby’s overall comfort.

How Absorbent Materials In Our Nappies Work

The super absorbent core that soaks up wee in our nappies is a smart, layered system that works together:

• Soft Upper Layer: Quickly pulls liquid away from your baby's skin

• Wetness Distribution System: Crafted from an optimized cellulose layer covered by a polyester fiber layer, efficiently captures liquid and distributes it evenly into the core.

• Super absorbent material: Traps and locks liquid right where it belongs—thanks to the innovative, super absorbent materials in the nappy core. 

Every layer in a Pampers nappy has its own job—from pulling away wetness to keeping it locked deep in the core, well away from your baby’s sensitive skin.

What Materials Help Nappies Absorb Liquid and How Do They Work Together?

Here’s a simple look at what does the heavy lifting inside a nappy. Let’s break down the Pampers' trusted nappy absorbent materials:

The clever design of Pampers nappies layers work as a team – soaking, spreading and locking away everything your little one throws at them, so you don’t need to worry about their comfort or leaks.

Soft Upper Layer

This layer sits right next to your baby’s bum and works hand-in-hand with each nappy absorbent material below the surface.

• Lets moisture pass through in no time

• Keeps the surface touchable dry 

• Soft and comfortable against baby’s skin

Wetness Distribution System

Just under the soft upper layer Pampers nappies have a wetness distribution system. It is a double layer structure made from polyester fibres at the top and a layer of soft, optimized cellulose fibres below. This fluff pulp comes from FSC® certified forests and other controlled sources.  Think of the wetness distribution system as the 'first responder', getting rid of liquid quickly so your baby's skin doesn't stay wet. Alongside other nappy absorbent materials, it helps deliver dryness fast after every gush.

•   Grabs moisture in a flash

• Spreads it out so it doesn’t pool in one spot and directs it to the super absorbent material

• Sourced from FSC® certified forests and other controlled sources.

Super Absorbent Material

What’s the super absorbent material in nappies? That’s the gel stuff you hear about, which does the all-important job of soaking up instantly and storing liquid as a core absorbent material in nappies.

• It can take in up to 30 times its own weight liquid in seconds

• It’s brilliant at absorbing liquid and turning it into a gel, which helps to stop leaks and ensures a dry surface against your baby’s skin.

• Keeps moisture locked away even under pressure, so your baby stays comfy and dry.

Imagine it like tiny magical beads, soaking up liquid and holding onto it – even when your little one is on the move.

Why Absorbency Matters for Your Baby’s Comfort

Your little one’s skin can be irritated by dampness, so choosing nappies with high-performing nappy absorbent material is essential. Keeping your baby’s skin comfy and dry is important as it can help:

• Reduce redness and chafing linked to residual wetness

• Support skin’s natural barrier

• Lower the chances of nappy rash.

So, think of a nappy as a super-sponge: unlike a soggy old towel that releases moisture when squeezed, it grabs moisture and locks it away where it can’t cause trouble, all thanks to innovative super absorbent material.

Our research has shown¹ that advances in nappy technology over the years — including improvements in absorbent materials like super-absorbent gel— have helped reduce the frequency and severity of nappy rash.

We know that a baby’s skin is affected by several factors inside the nappy, including moisture, friction, and contact with urine and stool. When skin is exposed over longer time to moisture, it can disrupt the skin’s natural barrier and make irritation more likely. 

That’s why modern Pampers nappies are designed to help manage these challenges. Our absorbent core, which includes super-absorbent gel, works to lock wetness away from your baby’s skin, while carefully designed layers help reduce friction and keeps the nappy surface dry to the touch.

Together, these features help support a more balanced skin environment — keeping your baby’s skin healthy, comfortable, and protected, day and night.

The Bottom Line

The absorbent materials in Pampers nappies are working together to keep your baby dry, comfortable and happy.

• The upper layer actively funnel liquid away from baby’s skin and distribute it evenly over the core. This way the surface stays dry to the touch and keeps your baby’s skin protected.

• The super absorbent material in the core locks away fluids so nothing comes back out, even under pressure.

When you know how all this absorbent technology works, you’ll feel even better about what’s in your baby’s nappy – and can get on with enjoying the snuggles, giggles and all the little moments together.
