Overview
Diglycerin (also known as diglycerol) is a polyol produced by the controlled condensation of two glycerol molecules, forming an ether bond with the elimination of one water molecule. The product is typically a mixture of isomeric compounds (e.g., 1,2- and 1,3-diglycerin) with variations in the position of the ether linkage. This structure provides excellent water solubility, humectant properties, and mildness, making diglycerin a valuable ingredient in food, cosmetic, and pharmaceutical formulations.

Applications

• Food industry: Used as a humectant, emulsifier, and texture stabilizer in confectionery, dairy products, margarines, and baked goods to improve consistency, extend shelf life, and maintain emulsion stability.

• Cosmetics and personal care: Acts as a moisturizer and skin conditioner in creams, lotions, hair conditioners, and other products; enhances texture, spreadability, and emulsion stability.

• Pharmaceuticals: Employed as a humectant, stabilizer, and solubilizer in topical formulations, ointments, and drug delivery systems.

• Industrial: Used as a solvent, plasticizer, and humectant in polymer production and specialty chemical formulations.
