Pharmaceutical Uses of Alginate
Since the mid-1970s, different forms of alginates such as alginate salt, alginic acids and propylene glycol alginates have been used successfully in pharmaceutical applications. Alginates are extensively used in pharmaceutical applications due to their unique properties. Some of the applications wherein alginates are used include film formers, disintegrants, for controlled release and control of gastric reflux as well as thickening and stabilization. These are but a few of the pharmaceutical applications in which alginate have been used. One of the advantages of alginate is that it hydrates quickly whether in cold or hot water. Alginates are also known to form gels that are thermally irreversible as well as clear, uniform and glossy films. In addition, when alginates are mixed along with water, it easily changes to alginic acid in a below 4 PH. Some of the other uses of alginates in the pharmaceutical field include:
Alginate Uses in Pharmaceuticals
Pharmaceutical Grade Alginate
Pharmaceutical grade sodium alginate, also called as, is a kind of white or light yellow granular or powder, which is almost odorless and tasteless
Alginates are known as natural polymers and are used widely in the food industry because of their qualities of non-toxicity, biodegradable, biocompatible and easy availability. In the pharmaceutical industry, however, it is the bioadhesive quality of alginates that makes it really useful. They can be used and formulated as matrices, gels, microspheres, membranes and more.>
The alginate can also serve as a chelator, a substance that can remove the heavy metals – toxins – in your bloodstream simply by binding them. There are heavy metals in the bloodstream because of reasons including diet, exposure to certain materials and to environment. In a study, it’s been found that specified doses of sodium alginate can effectively reduce the absorption of strontium, a heavy metal known to cause problems such as bone cancer, Hodgkin’s disease, leukemia and more.
Compared to placebo, alginate has shown greater weight loss that can be attributed mainly to the effective reduction of body fat’s percentage. On the other hand, in the ITT analysis, there is not any difference between the treatment groups in terms of the plasma concentrations of insulin, ghrelin, glucose, C-reactive protein, lipid metabolism and HOMA-IR.
One common use for alginate is in cosmetics wherein it is used for its functionality as a moisture retainer and thickener. With these qualities, alginates have been used in several applications such as in retaining a lipstick’s color on the lip surface. It works so by the alginates forming a gel-like network that works on retaining the color of the lipstick.

Some of the more common pharmaceutical uses of alginates in drugs, supplements and cosmetics.
Kelp seaweed is the raw material that alginate is extracted from. Unlike land-based vegtable material, that is made up of cellulose, kelp structure is wholly alginate based.
