Calcium lactobionate

Calcium lactobionate (CAS 5001-51-4 ), also identified by E-number E399 , is the calcium salt of lactobionic acid used across food, cosmetic, and pharmaceutical manufacturing.

It functions primarily as a chelating agent, humectant, and stabilizer, helping formulators manage mineral interactions, moisture retention, and oxidative stability in finished products.

In food and beverage manufacturing, it acts as a firming agent and sequestrant, protecting product texture and color by binding trace metals that would otherwise accelerate spoilage.

Pharmaceutical manufacturers use it as a calcium supplement source and as a stabilizing excipient in oral and parenteral formulations where controlled mineral delivery is required.

In cosmetic and skincare formulations, its moisture-binding capacity supports hydration claims in serums, creams, and leave-on treatments for various skin types.

It also serves as a processing aid in dairy applications, where calcium fortification and texture stabilization are required simultaneously to maintain high product quality.

Calcium lactobionate is supplied as a white crystalline powder, available in both anhydrous and monohydrate forms. Standard grades include food-grade and pharmaceutical-grade material.

Our inventory meets USP or Ph. Eur. specifications. Packaging is typically offered in multi-kilogram bags or drums suited to industrial procurement volumes.
