It's Mechanism is simple 

​

1. Osmotic action that assists autolytic debridement

Maltodextrin exerts a gentle osmotic pull, drawing excess exudate, slough and debris toward the surface. This helps:

•Hydrate and loosen devitalised tissue

•Reduce surface bioburden

•Support natural autolysis without cytotoxicity

Clinically, this means cleaner wound beds with less mechanical trauma. 

 

2. Formation of a moist, protective gel layer

When maltodextrin interacts with wound fluid, it forms a viscous gel that:

•Maintains an optimal moist wound environment

•Protects exposed structures

•Prevents adherence to secondary dressings

•Supports granulation and epithelial migration

This gel layer is central to promoting orderly tissue repair.

​

3. Provides an energy substrate for reparative cells

Because maltodextrin is composed of short glucose chains, it can serve as a readily available energy source for:

•Fibroblasts

•Keratinocytes

•Macrophages

This is particularly relevant in chronic or stalled wounds, where cellular energy demand is high.

​

4. Helps reduce odour and surface bacteria

By drawing fluid and debris into the gel matrix, maltodextrin:

•Reduces the nutrient load available to bacteria

•Lowers surface bioburden

•Assists with odour control

It is not an antimicrobial, but it supports a cleaner wound environment.
