In absorbent hygiene products, the quality of a material is assessed over time. Initial absorption is only one part of the performance. What comes next is the way the liquid is distributed, the stability of the core and retention under load during use.

For those designing diapers, feminine hygiene products, incontinence products or medical absorbent solutions, these are not secondary details. 

They affect comfort, perceived safety and consistency of performance, and become even more relevant when the product design needs to incorporate materials certified for industrial composting without compromising its application requirements.

Airgel g-grade and Spongel within the airlaid structure

Airgel g-grade was designed to work within this balance. Our airlaid is certified OK Compost INDUSTRIAL for industrial composting and was developed to provide high levels of absorption and retention without the use of fossil-based chemical SAPs. Within the product, it helps absorb the liquid, distribute it through the structure and keep it stable even when the absorbent core is under pressure.

Airgel g-grade contains Spongel, Magic’s patented superabsorbent powder. Within the airlaid structure, Spongel provides the material’s superabsorbent function: it absorbs and retains liquid, contributing to comfort, safety in use and the behaviour of the core during use.

Industrial compostability and technical function in hygiene products

In the hygiene sector, a material certified for industrial composting still has to behave as a technical material. It must absorb and retain liquid, keep the core stable and integrate into the production process. 

For Airgel g-grade, certified industrial compostability is not an added feature: it has been part of the material’s development from the outset. 

From hygiene to food packaging: how liquids behave over time 

This approach to material design can also be applied to absorbent pads for packaged fresh food. 

In this case, managing exudate responds to different needs, linked to pack quality, the visual presentation of the product and shelf-life stability. 

The way the liquid behaves over time affects very practical aspects: how it is distributed within the absorbent structure, its ability to remain inside the pad and the perception of order and quality of the packaged product. 

Across such different applications, one point remains the same: absorbent performance depends on how the liquid is managed over time.
At Index26 in Geneva, we will tell this story through Airgel g-grade: the outcome of a process that began with Spongel and evolved into an airlaid structure certified for industrial composting, designed for use in absorbent products.

From raw material to structure.
From superabsorbent capacity to liquid management over time.

We look forward to seeing you at Index26 – Stand 2449.
