Magnesium Sulphate X-Hydrate (Dried)
Concentrated magnesium and sulfate delivery for RO remineralization, food, and pharmaceutical use.
Chemical Formula
MgSO₄ ⋅ xH₂O
Density
2.66 g/mL
Apperance (Form)
White Fine Crystalline Powder
Particle Size
0.5 – 1.5 mm
Magnesium Sulphate X-Hydrate (Dried) is a food-grade, high-purity mineral salt with a lower water content than standard heptahydrate, giving it a higher magnesium concentration by weight. It's used to restore magnesium and sulfate levels in RO-treated water, balance mineral profiles, and support food, beverage, and pharmaceutical formulations.
Formulated for efficient, high-concentration magnesium delivery:
Certified food grade (FCC, E518) for use in food, beverage, and pharmaceutical applications
High purity (99–100.5% assay) with a concentrated 15% magnesium content by weight
Fine crystalline powder for consistent, efficient dosing
Stable for up to 5 years when stored in a dry, well-ventilated environment
