Sodium lactobionate is widely used in the pharmaceutical industry as an excipient in injectable formulations. It serves as a stabilizer and bulking agent in lyophilized (freeze-dried) drugs, helping to maintain the integrity and efficacy of the product during storage. Its ability to form stable complexes with metal ions makes it useful in chelation therapy, where it helps in the removal of excess metals from the body. Additionally, it is employed in organ preservation solutions, particularly for transplant organs, due to its osmotic properties and ability to protect cells from damage. In cosmetics, it acts as a humectant, retaining moisture in skin care products. Its non-toxic and biocompatible nature makes it suitable for various medical and cosmetic applications.
