Used extensively as a desiccant to control humidity and prevent moisture damage in packaging, particularly for electronics, pharmaceuticals, and food products. Its self-indicating property, which changes color when saturated, makes it easy to monitor its effectiveness. Commonly employed in storage containers, shipping packages, and museum display cases to protect sensitive items from humidity. Also utilized in laboratories to dry air or gases and as a moisture absorber in industrial processes. Its non-toxic and inert nature ensures safe use across various applications.
