alginate

A gelatinous polysaccharide extract from brown algae and salt of alginic acid, which is a linear polymer of mannuronic and glucuronic acids, found in the cell walls of algae. It is widely used in processed foods and in medicinal, industrial and household products, including swabs, filters and fire retardants.

Source
Laminaria spp and Macrocystis pyrifera; a chemically different version of algin is produced by the bacterium Azobacter vinelandii.
 
Dentistry
Alginate can be formulated with gypsum into a plaster like compound to take impressions for crown and bridgework.
 
Surgery
Alginates are used as foam, clotting agents and gauze in absorbable surgical dressings and packing.
 
Wound care
Alginate dressings are derived from seaweed made of soft non-woven fibres, and are available as pads, ropes or ribbons. Alginate dressings are extremely lightweight, absorb many times their own weight, form a gel-like covering over the wound, and maintain a moist environment. They are best used for wounds with significant exudate.

Pros
Especially useful for packing exudative wounds; do not physically inhibit wound contraction as does gauze; highly absorbent.
 
Cons
Requires a secondary dressing; too drying if wound has little exudate.
