  • Applications

    4'-Galactosyllactose, CAS 6587-31-1, is an oligosaccharide isomer within the galactooligosaccharide (GOS) family and is commonly used as a prebiotic ingredient in foods and dietary supplements; it is frequently evaluated for inclusion in infant formula and other fortified foods; as a soluble dietary fiber, it can support gut microbiota and contribute to dietary fiber intake; it is also used in animal nutrition as a prebiotic additive in feed formulations; in some product development contexts it is explored for cosmetics/personal care as a humectant or texture modifier; and in pharmaceutical contexts it is sometimes considered as an excipient or stabilizer in certain formulations.
