Description and Uses
Calcium Alginate is the calcium salt of alginic acid, a natural polyuronide constituent of certain brown algae. Calcium alginate is prepared by the neutralization of purified alginic acid with appropriate pH control agents, or from sodium alginate by metathesis with appropriate calcium salts.
Alginate, a colloidal polyuronic acid structural molecule capable of gelation, is used in the preparation of colloidal biodegradable structures such as gels, biofilms, beads, nanoparticles, and microcapsules suitable for applications that range from gel based separation technologies to drug delivery and cell preservation.
Calcium alginate has been around for years. More recently, it has been added to wound gels, hydrocolloids, and cleansers. Silver, a known antimicrobial agent, also has been added to many wound products, including calcium alginate. Unadulterated calcium alginate comes in the form of a flat square or mat (in many sizes) or a rope. The ropes can be manipulated to fit easily in wound cavities. Although one of its stated uses is to provide homeostasis, calcium alginate is more commonly thought of as the dressing that can absorb 20 times its weight in exudate, soak up loose debris from the wound bed, provide an optimal environment for healing, and provide a painless dressing change. This study is a reminder that calcium alginate is a valuable tool in our wound care arsenal.
Calcium Alginate is the calcium salt of alginic acid which functions as a stabilizer and thickener. the partial obtainment of calcium alg- inate by the reaction of the water-soluble alginate with calcium ions is used to obtain viscosity and gel formation. it is used in icings, imitation pulp, dessert gels, and fabricated fruits.
