  • Applications

    Galactitol (dulcitol) is primarily used as a chemical building block and processing aid across several industries. It serves as an intermediate in the synthesis of galactose-derived glycosides and related pharmaceutical/biotech compounds. In cosmetics and personal care, it functions as a humectant and stabilizer, helping to retain moisture in formulations. It can act as a plasticizer or processing aid in certain polymers and coatings, improving flexibility and handling. It is also used as a bulking agent or functional additive in pharmaceutical formulations and can be evaluated for moisture-retaining applications in coatings and inks, with exact use governed by formulation and local regulations.
