Glucosamine sulfate

Glucosamine sulfate (CAS 29031-19-4) is an amino sugar salt sourced primarily from shellfish chitin or produced via fermentation for non-animal supply chains. Glucosamine sulphate is the preferred spelling in several European markets.

This makes it a distinct commercial search term for importers and formulators. It is used across pharmaceutical and personal care manufacturing as a bioactive ingredient and humectant for various industrial applications.

In pharmaceutical manufacturing, it is the active ingredient in oral dosage forms such as tablets, capsules, and sachets targeting joint health. Personal care formulators incorporate it into moisturizing creams and serums.

Its humectant properties support skin hydration and barrier function in cosmetic products. It also appears in topical formulations where pH buffering is required to maintain product stability across a defined range.

Nutraceutical producers use it in combination products alongside chondroitin or collagen for joint-support supplement lines. Glucosamine sulfate is supplied as a white to off-white crystalline powder for easy processing.

It is available in pharmaceutical-grade specifications including USP and Ph.Eur. compliance. Food-grade and cosmetic-grade variants are also available depending on the intended application and regulatory needs.

Stabilized forms, typically combined with sodium chloride or potassium chloride, are standard in the market. These should be specified at the time of inquiry to ensure the correct chemical profile for your formulation.
