The exchange of calcium ions within the dressing with sodium ions, which are present in the exudate, transforms the alginate into a moist gel.

Facilitates moist wound healing

by maintaining a moist environment.

Has haemostatic properties

due to calcium ion release from the alginate dressing in contact with body fluids.

Reduces risk of maceration

Only one layer of exudate is maintained at the wound surface but excess exudate is absorbed.

Helps to clean the wound

Bacteria are trapped in the gel formed by the exudate absorbed and are then removed during dressing change.
