AlginateHighly absorbent, biodegradable alginate dressings are a unique class of wound care dressings that are derived from seaweed fibres. Composed of polysaccharides derived from brown algae , alginate dressings are constructed as a mesh of alginate fibers and come in calcium alginate or calcium sodium alginate forms. Characterized by their high absorption and facilitation of ion exchange, alginate dressings can absorb 18 to 20 times their own weight making them ideal for heavy exudate wounds.

Calcium alginate dressings are specific type of alginate dressing that uses calcium ions to facilitate wound healing. Sodium ions from the wound exudate are exchanged with calcium ions from the calcium alginate dressing, resulting in the creation of a hydrophilic gel. The hydrophilic gel stimulates rapid wound healing via moisture balance, granulation, and epithelialization. Alginate fibers trapped within a wound are readily biodegraded as the alginate breaks down to monosaccharide components within the wound facilitating easy dressing removal.

The properties of alginate dressings make them ideal for heavy exudate wounds, chronic ulcers, pressure and skin ulcers, surgical wounds, and bleeding wounds. Learn more about our unique line of wound care products and the many advantages of alginate dressings.
