Galactaric acid

Galactaric acid (CAS 526-99-8 ), also known commercially as mucic acid, is a naturally derived dicarboxylic acid obtained primarily from the oxidation of galactose or lactose. It functions as a chelating agent, pH buffer, and humectant across pharmaceutical, food, cosmetic, and water treatment applications.

In pharmaceutical manufacturing, it acts as a sequestrant and acidulant in tablet formulations, helping to stabilize active ingredients sensitive to metal ion interference. Water treatment formulators incorporate it to chelate calcium and magnesium ions, reducing scale formation in process systems.

In personal care products, its moisture-binding capacity supports humectant functionality in creams, serums, and leave-on treatments where sustained hydration is a formulation target. Food-grade applications include use as a buffering acid and mild chelating agent in processed food systems.

These food-grade systems often require controlled pH and metal sequestration to maintain product stability. Galactaric acid is supplied as a white crystalline powder and is available in technical and pharmaceutical-grade specifications for various industrial needs.

Purity levels typically range from 98% upward depending on the intended use and specific industry requirements. Buyers sourcing for regulated applications should confirm compliance documentation against relevant pharmacopeial or food-safety standards prior to procurement.

This includes verifying adherence to USP , BP , or EP standards where applicable for medicinal or high-purity uses. Ensuring these quality benchmarks are met is essential for maintaining consistency and safety in complex chemical formulations.
