Calcium Sulfate Dihydrate (CAS 10101-41-4), commonly known as gypsum, is a chemical compound with a remarkable range of applications, thanks to its availability in various grades tailored to specific industry requirements. For procurement professionals and R&D scientists, understanding these differences is crucial for selecting the appropriate material and ensuring the success of their end products. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-quality calcium sulfate dihydrate in multiple grades, ensuring our clients can buy exactly what they need.

Industrial Grade Calcium Sulfate Dihydrate: This is the most broadly used grade, characterized by its versatility and cost-effectiveness. Industrial applications span across construction materials such as cement, plaster, and drywall, where it acts as a retarder, binder, and filler. It is also utilized in the paint and paper industries as a filler to improve opacity and brightness. In agriculture, it serves as a vital soil conditioner to improve structure and provide essential nutrients. While purity standards are important, they may not be as stringent as for food or pharmaceutical grades. When purchasing industrial grade, consider bulk quantities for applications like cement manufacturing or large-scale agricultural use.

Food Grade Calcium Sulfate Dihydrate: This grade adheres to strict purity standards mandated by food safety regulations globally. It is recognized as a safe food additive (E516) and is used extensively for its nutritional benefits (calcium fortification) and functional properties in food processing. Applications include acting as a coagulant in tofu production, a firming agent in canned fruits and vegetables, a dough conditioner in baking, and a yeast nutrient. Food manufacturers must buy food-grade calcium sulfate dihydrate from suppliers who can guarantee compliance with relevant food safety certifications and purity requirements.

Pharmaceutical Grade Calcium Sulfate Dihydrate: This is the highest purity grade, manufactured under stringent Good Manufacturing Practices (cGMP). It is primarily used as an excipient in the pharmaceutical industry, serving as a filler and diluent in tablet and capsule formulations. Its inertness, compressibility, and controlled particle size are critical for producing stable and effective dosage forms. Pharmaceutical companies looking to buy this grade require suppliers who can provide comprehensive documentation, including Certificates of Analysis (CoA) that verify purity, absence of contaminants, and compliance with pharmacopoeial standards (USP, EP, BP, etc.).
