Pharmaceutical Chemistry
Magnesium Sulfate Heptahydrate
Formula:
MgSO₄·7H₂O
GOST/CAS:
CAS 10034-99-8
Magnesium sulfate heptahydrate (a highly purified pharmaceutical substance, also widely known as Epsom salt or bitter salt) consists of colorless crystalline granules or a white crystalline powder that is excellently soluble in water. Thanks to strict quality control regarding purity levels and the total absence of toxic impurities, this product serves as an indispensable base component in the production of pharmaceuticals, IV and infusion solutions, dietary supplements, as well as premium cosmetics and spa products.
Applications
Pharmaceuticals & Medicine: Used as an Active Pharmaceutical Ingredient (API) for manufacturing injectable and infusion solutions, oral suspensions, laxatives, and choleretic medications. It is widely utilized in formulations for rehydration and body detoxification.
Dietary Supplements & Sports Nutrition: Included in vitamin and mineral complexes to treat magnesium deficiency, support nervous and cardiovascular system functions, and aid in rapid muscle recovery after intensive workouts.
Cosmetics & SPA (Epsom Salt): The core component for therapeutic flotation and Epsom salt baths. It effectively relieves muscle tension, draws out toxins through the skin, improves microcirculation, and serves as a premium base for body scrubs and anti-cellulite wraps.
Laboratory Practice & Biotechnology: Applied as a nutrient medium component for microorganisms and cell cultivation, as well as a high-purity reagent for various analytical laboratory tests.
Key Advantages
Pharmaceutical Grade Purity (High Purity): Fully complies with the rigid standards of major international pharmacopoeias (USP, EP, BP). Minimal presence of heavy metals, arsenic, and secondary salts guarantees maximum safety.
Stable Granulometric Composition: The crystals feature excellent free-flowing properties, resist caking or clumping when stored properly, allow precise dosing, and dissolve instantly in water without leaving any residue.
High Bioavailability: When dissolved, magnesium and sulfate ions are quickly and efficiently absorbed by the body, whether administered orally, intravenously, or transdermally.
Versatility & Safety: A physiologically friendly and non-hazardous ingredient. It does not cause allergic reactions under proper topical use, contains no volatile organic compounds (VOCs), and is completely environmentally safe.
Storage & Transportation
- Store in dry, clean, well-ventilated warehouses in the original, tightly sealed packaging of the manufacturer.
- Magnesium sulfate heptahydrate is prone to efflorescence (losing water molecules) in dry, warm air. Thus, maintaining a stable temperature range (+5°C to +25°C) and relative air humidity below 70% is critical.
- Avoid exposure to direct sunlight, humidity, and keep away from heat sources.
- Transportation is permitted by all modes of covered transport in accordance with cargo carriage regulations. The product is not classified as a dangerous good (non-hazardous, exempt from ADR regulations).
- Shelf Life: 3 years from the date of production (provided the original packaging remains hermetically sealed).
