Alginate is initially extracted from the cell wall of brown seaweeds. Alginate dressings can be in the form of freeze-dried, porous (foam) sheets or flexible fibres. Flexible fibres are used to treat cavity wounds. The alginate will form a gel in contact with the exudates of the wound and give it a strong absorbent power. [2]
In modern typical usage, the solution is applied to the wound once daily for lightly to moderately exudative wounds, and twice daily for heavily exudative wounds or highly contaminated wounds. [3] The healthy skin surrounding the wound should preferably be protected with a moisture barrier ointment (e.g., petroleum jelly) or skin sealant as ...
A container with cream. Topical cream formulation is an emulsion semisolid dosage form that is used for skin external application. Most of the topical cream formulations contain more than 20 per cent of water and volatiles and/or less than 50 per cent of hydrocarbons, waxes, or polyethylene glycols as the vehicle for external skin application.

The algae is then treated with an acidic solution to help disrupt cell walls, which converts the alginate salts into insoluble alginic acid; a subsequently applied alkaline solution (pH 9-10), usually sodium carbonate, converts it back into water-soluble sodium alginate, which is then precipitated.

The 3D polymeric network of hydrogels is highly hydrated with 90-99% water w/w; it is capable of binding many times more water molecules when assembled than in the uncross-linked state. [2] [3] Hydrogel dressings can absorb up to 600 times their initial amount of water, including fluid-based wound exudates.
Wound cleansing forms an integral part of wound management and generally suggests the application of a fluid to aid the removal of surface contaminants, bacteria, and debris from the wound surface and surrounding skin. [25] Water as a cleansing agent, especially in chronic wounds has been proposed [23] and is widely used [26] especially in the ...
