Opinions

Is oral magnesium sulphate hydrate still worth buying as a supplement, or should buyers switch to other magnesium forms?

Don't write off the oral channel entirely. In pharma, magnesium sulphate injection remains a core anticonvulsant and tocolytic raw material, and that demand is steady and specification-driven. The distinction matters: supplement-grade oral use is shrinking, but pharmaceutical-grade injectable demand is a separate, more defensible market with tighter quality requirements.

How do industrial-grade and agricultural-grade magnesium sulphate hydrate specifications differ for buyers?

For buyers, the practical split is storage and handling. The heptahydrate is the workhorse but can cake in humid conditions, which is why some downstream users move to monohydrate, made by drying the hydrate at high temperature to leave only one water molecule. That version resists caking and travels better, though it costs more to produce.

Overview

Magnesium Sulphate Hydrate (CAS 22189-08-8) is a white crystalline solid, soluble in water, alcohol, and glycerin but insoluble in acetone, with a density of 2.57 g/mL at 25°C and a melting point of 150°C (dec.). It serves as a versatile magnesium and sulphur source across agricultural, industrial, and pharmaceutical applications.

Agricultural: used as a magnesium supplement in fertilisers and animal feed.
Pharmaceutical: acts as a laxative and in blood-pressure management.
Industrial: applied in papermaking, ceramics, explosives, and as a drying agent.
Personal care: used in bath salts and topical treatments for skin conditions.

China is a major producer of magnesium sulphate, with abundant raw materials from magnesite deposits in Liaoning and salt-lake brines in Qinghai. Domestic production covers heptahydrate, monohydrate, and anhydrous grades, with output exceeding domestic demand and supporting steady exports. Manufacturing routes include sulphuric acid digestion of magnesite and seawater bittern processing.

Key domestic producers:
Shandong Jiuzhong Chemical – high-purity industrial and agricultural grades with export capability.
Shandong Haihua – large-scale industrial-grade production.
Jiangsu Kelunduo Food Ingredients – food and pharmaceutical grades.
Hebei Meishen Technology – specialty and high-purity products.
Weifang Hai Zhiyuan Chemical – industrial-grade supply.
