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]
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.

Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture.
It protects the wound from bacterial contamination, absorbs wound discharge, and digests necrotic tissues. It is mostly use as secondary dressing. However, it is not used in wound with high discharge and neuropathic ulcers. [9] Alginate dressing: This type of dressing is made up of either sodium or calcium salt of alginic acid. This dressing ...

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. [4]
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 ...
