Sorbitol is a white, water-soluble polyol compound that naturally occurs in fruits and berries and can also be industrially synthesized via the catalytic hydrogenation of sucrose. It has a mild sweetness and hygroscopic properties, serving as a sugar substitute (E420) and humectant in the food industry, as well as being used in the synthesis of vitamin C and resin raw materials. In the pharmaceutical field, it is commonly employed in the preparation of injectable solutions, oral liquids, and other formulations. Derivatives such as dibenzylidene sorbitol are utilized in industrial applications like nucleating agents for polyolefin resins.
