Description

Sodium Lactobionate is the sodium salt of lactobionic acid, a polyhydroxy acid derived from lactose. This high-purity compound is valued for its excellent chelating, moisturizing, and stabilizing properties in sensitive formulations. It serves as a critical excipient and active ingredient for manufacturers in the pharmaceutical, cosmetic, and biotechnology sectors seeking reliable, consistent quality.

Application

• Pharmaceutical Excipient: Used as a stabilizer, cryoprotectant, and bulking agent in lyophilized (freeze-dried) injectable formulations, including vaccines and biologics.
• Chelating Agent: Effectively binds metal ions (e.g., calcium, iron) in ophthalmic solutions, dialysis solutions, and topical preparations to enhance stability.
• Cosmetic & Personal Care: Functions as a powerful humectant and moisturizer in high-end skincare products, serums, and creams due to its hygroscopic nature.
• Cell Culture & Biotechnology: Employed in certain cell culture media and as a component in organ preservation solutions.
• Food Additive (where approved): Potential use as a sequestrant and stabilizer in specialized food products.
• Chemical Synthesis: Serves as a chiral building block or intermediate in organic synthesis and pharmaceutical research.

Quality Control

Our Sodium Lactobionate is manufactured under a quality management system and undergoes rigorous analytical testing to ensure it meets stringent specifications for purity and consistency. We can supply material suitable for pharmaceutical development and other high-purity applications. A comprehensive Certificate of Analysis (COA) documenting identity, assay, impurity profile, and other critical parameters is provided with each batch.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
