Hydrocolloid technology
On contact with wound exudate, the hydrocolloid matrix forms a cohesive gel which supports moist wound healing.

The hydrocolloid formulation of the DuoDERM® Dressings is unique, consisting of a cross-linked honeycomb matrix made from a proprietary mix of sodium carboxymethylcellulose, gelatin, pectin and adhesive polymers.
Key properties of the three hydrocolloids contained in the DuoDERM® Dressing formulation:
| |
|
|
1. Sodium CMC (NaCMC)
|
- Polysaccharide, rapidly absorbs fluid and gels, provides instant absorbency.
|
|
2. Pectin
|
- Polysaccharide, absorbent.
- Provides a lower pH to the formulation that more closely matches that of human skin.
- Provides medium term absorbency
|
|
3. Gelatin
|
- Protein, provides longer term absorbency.

DuoDERM® Dressings incorporate the unique ConvaTec hydrocolloid formulation that distinguishes them from other hydrocolloid dressings.
