Powder shape, white to light yellow indefinite, odorless tasteless, insoluble in water. The molecular chain of sodium alginate contains a large number of hydroxyl and carboxyl groups. Calcium chloride solution (CaCl2) is used as a crosslinking agent to form a crosslinked calcium alginate polymer with high water content and good biodegradability and biocompatibility, which can be used in food processing and pharmaceuticals.

<h3>Overview</h3>
<p><strong>Calcium alginate</strong> (CAS: 9005-35-0) is a natural polysaccharide derived from brown algae via acid extraction and calcium salt formation. Its molecular formula is typically represented as (C6H7O6Ca)n. This hydrophilic polymer features high biocompatibility and rapid gelation upon contact with aqueous fluids.</p>
<h3>Application</h3>
<ul>
<li><strong>Wound Care:</strong> Primary dressing for exuding chronic wounds to maintain a moist environment.</li>
<li><strong>Dental Impression:</strong> High-accuracy material for capturing dental arches in prosthodontics.</li>
<li><strong>Food Industry:</strong> Gelling agent and stabilizer in dairy products and processed foods.</li>
</ul>
<h3>Precautions</h3>
<p>Store in a cool, dry place below 25°C to prevent moisture absorption and microbial growth. Avoid inhalation of dust; wear appropriate respiratory protection during handling. Not intended for intravenous administration or use on deep puncture wounds without medical supervision.</p>
