This compound, D-(-)-trehalose 6,6'-dibehenate, is a specialized lipid derivative primarily used in the pharmaceutical and cosmetic industries. In pharmaceuticals, it serves as an excipient and lipid component in advanced drug delivery systems, such as lipid nanoparticles and liposomes, particularly for mRNA and nucleic acid therapeutics. It enhances the stability, solubility, and cellular uptake of active ingredients, while also aiding in the formulation of lyophilized (freeze-dried) products to maintain the integrity of proteins and sensitive molecules during storage.

In cosmetics, it is valued for its moisturizing, emollient, and skin-conditioning properties, helping to retain moisture and form protective barriers against environmental damage. It is commonly incorporated into creams, lotions, and serums, with its stabilizing effects ensuring long shelf life. Its biocompatibility and non-toxic nature make it ideal for these topical applications.
