The Science Behind MoliCare®’s Materials
At MoliCare®, our products are built from carefully selected raw materials that work together to efficiently absorb fluid, protect the skin, and reduce the risk of leaks. Every material choice is guided by evidence and performance testing, with a focus on high absorbency, reliable leakage protection, pH-balanced skin contact, and everyday comfort. In this guide, we explain the science behind those materials, where they sit within each product, how they function, and what happens to them after use.
At a glance: What Makes MoliCare® Materials Different
-
A multi-layer absorbent core that combines super absorbent polymers (SAP) with cellulose to manage fluid quickly and effectively
-
pH-balanced material technology developed to help maintain the skin’s natural protective barrier
-
Breathable, non-woven surface layers that allow air circulation while keeping moisture away from the skin
-
Elasticated components and leak guards are designed to support a secure fit and limit side leakage
How MoliCare® materials work together
MoliCare® disposable products are designed as integrated systems, with each layer performing a specific role at a precise stage of fluid management. When liquid reaches the product, the top layer allows fast intake, guiding fluid away from the surface and into the inner structure. From there, the distribution layer evenly distributes the liquid across the core, preventing pooling and helping the product perform consistently across its full absorbency area.
Once absorbed, liquid is securely retained within the core, where it is locked away to reduce rewetting and help keep the surface feeling dry. At the same time, materials in contact with the skin are selected to support comfort and skin protection during wear. This layered approach is used consistently across most MoliCare® disposable pads, pull-ups, and briefs, with variations in shape and absorbency level rather than in core material principles.
The raw materials we use at MoliCare®
Disposable MoliCare® products are made using a carefully balanced combination of absorbent materials, textile-like comfort layers, and structural components that support fit and performance. Each material group plays a distinct role, from managing fluid to maintaining comfort and product stability during wear. Material selection changes only when the product’s function differs; for example, reusable underwear uses washable textiles rather than disposable absorbent cores.
What’s in our products?
Most disposable MoliCare® products are constructed from a defined set of functional layers, each positioned to manage fluid, support comfort, and maintain product integrity during use. Rather than relying on a single material, these products use a layered structure that separates intake, absorption and fit into distinct components that work together as one system.

Our materials explained
Super absorbent polymers (SAP)
Super absorbent polymers are synthetic materials designed to absorb liquids and form gels. Once liquid enters the absorbent core, SAP chemically binds it, preventing it from spreading back to the surface. This material is located within the absorbent core of the product and is used across most disposable MoliCare® pads, pull-ups, and briefs. By immobilising fluid, SAP plays a key role in maintaining dryness, supporting leakage protection, and reducing odour during wear.
Cellulose (fluff pulp)
Cellulose fluff pulp is made from wood-based cellulose fibres (a complex carbohydrate which is a main part of plant cells) and forms a major part of the absorbent core. Its primary function is to take in liquid quickly and distribute it evenly throughout the core, allowing the product to use its full absorbent capacity. Cellulose is used in all main disposable MoliCare® incontinence products and works alongside SAP to support fast intake and consistent performance across the entire absorbent area.
Acquisition and distribution layer
The acquisition and distribution layer is made from specially structured fibres designed to manage the first contact with liquid. Positioned just below the top sheet, this layer draws fluid away from the surface and directs it into the absorbent core. It is used in premium disposable MoliCare® products across the range and plays an important role in keeping the surface dry while helping maintain a stable skin environment and pH balance.
Non-woven inner layer
The non-woven inner layer is a soft, textile-like synthetic material that sits against the skin. It allows liquid to pass through quickly while providing a smooth and comfortable contact surface. This layer is used in disposable MoliCare® pads, pants, and briefs. Its role is to support breathability and comfort during wear, helping to minimise friction and reduce the risk of skin irritation.
Breathable backsheet (protective film)
The breathable backsheet is a protective outer layer that prevents liquid from escaping the product while still allowing air to circulate. Located on the outside of disposable MoliCare® pads, pull-ups, and briefs, this layer acts as a barrier between the absorbent core and clothing. Its breathable design supports discretion and contributes to overall skin comfort during extended use. Made from textile like materials to minimise rustling for added discretion.
Elastic components and fastening systems
Elastic components and fastening systems include stretch panels, elastic threads, and re-fastenable tapes. These elements are positioned around leg cuffs, waistbands, and side panels, helping the product stay securely in place. Used primarily in MoliCare® briefs and pull-ups, these components support freedom of movement while reducing the risk of leakage caused by poor fit.
Did you know?
Most disposable MoliCare® products are built on the same core absorbent technology, with differences focused on shape, fit, and absorbency level rather than changes to the underlying materials.
Disposable vs. reusable – understanding the debate
The discussion around disposable and reusable incontinence products is complex, as each option involves different materials, usage, and environmental considerations. Rather than having a single “better” solution, the impact of each depends on how products are manufactured, used, cleaned, and disposed of over time. Most MoliCare® products are disposable, but both formats have advantages and limitations that are worth understanding.
Disposable products – pros and cons
Pros
Designed for single use, which supports consistent hygiene
Provide consistent absorbency and performance with every change
Do not require washing or drying between uses
Cons
Contribute to household waste after use
Rely on raw material production for each product cycle
Reusable products – pros and cons
Pros
Can reduce solid waste when used repeatedly over time
Do not require disposal after every use
Will appeal to users seeking a washable option
Much more eco-friendly than other disposable options
Cons
Suitable for lighter levels of incontinence only
Require regular laundering, increasing water and energy use
Depend on detergents and washing conditions for hygiene
Factor | Disposable | Reusable |
Hygiene | High and consistent | Wash at a hygienic 60° |
Resource use | Materials | Water and energy |
