Stachyose tetrahydrate

Stachyose tetrahydrate (CAS 10094-58-3, EC 207-427-3) is a naturally occurring tetrasaccharide composed of two galactose units, one glucose unit, and one fructose unit. Also known as lupeose hydrate or manneotetrose hydrate, it carries no assigned E-code and is classified under HS code 29400090.

In personal care formulations, stachyose tetrahydrate functions as a humectant and skin conditioner by attracting and retaining moisture within the stratum corneum, reducing transepidermal water loss. In food and nutrition applications, it acts as a prebiotic additive and chelating agent, sequestering metal ions that would otherwise accelerate oxidative degradation of sensitive ingredients.

Stachyose tetrahydrate is available as a white crystalline powder in food-grade and cosmetic-grade specifications. It is subject to REACH registration requirements for EU supply and should comply with applicable FCC standards for food-use applications. Packaging is typically offered in sealed moisture-barrier containers to preserve stability.
