Calcium alginate(CAS: 9005-35-0)

Calcium alginate (CAS: 9005-35-0) is a water-insoluble polymer that forms a gel-like structure when hydrated. It has a high molecular weight, typically ranging from 100,000 to 500,000 Da. The compound has limited solubility in aqueous solutions but can be dissolved in strong acids. It is relatively inert chemically but can react with acids to form monosodium alginate.

Calcium alginate (CAS: 9005-35-0) is synthesized by neutralizing sodium alginate with calcium ions in an aqueous solution. Common methods include using calcium chloride or calcium hydroxide as the neutralizing agent. The reaction typically has a high yield and involves simple mixing and pH adjustment steps.

Calcium alginate (CAS: 9005-35-0) is widely used in the pharmaceutical industry for drug delivery systems, as a matrix for controlled-release formulations, and in wound healing applications. It is also utilized in the food industry for gelling and stabilizing properties, in the textile industry for fabric softening, and in the cosmetic industry for skincare products.

When handling calcium alginate (CAS: 9005-35-0), it is important to wear appropriate personal protective equipment (PPE), such as gloves and goggles, to protect against skin and eye exposure. Store the material in a cool, dry place away from strong acids and bases. In case of spillage, use appropriate cleaning agents and ensure proper disposal. Always refer to the safety data sheet (SDS) for detailed handling instructions and emergency procedures.
