Magnesium Stearate (CAS 557-04-0) is a versatile chemical compound with applications spanning pharmaceuticals, food, cosmetics, and various industrial sectors. However, not all Magnesium Stearate is created equal. The specific requirements for each application necessitate different grades of purity, manufacturing standards, and regulatory compliance. As a leading manufacturer of Magnesium Stearate, we offer various grades to meet diverse client needs. Understanding these distinctions is crucial for procurement professionals seeking to buy Magnesium Stearate with the correct specifications.

Pharmaceutical Grade Magnesium Stearate is subject to the most stringent quality controls. It must comply with pharmacopoeial standards such as USP (United States Pharmacopeia), BP (British Pharmacopoeia), and EP (European Pharmacopoeia). This grade requires extremely high purity, with strict limits on heavy metals, microbial contamination, and specific impurities. Its primary function is as an excipient, particularly as a lubricant and flow aid in tablet and capsule manufacturing. When you seek pharmaceutical grade Magnesium Stearate, ensure your supplier can provide detailed Certificates of Analysis (CoA) confirming compliance with these standards.

Food Grade Magnesium Stearate also adheres to high standards, complying with regulations set by bodies like the FDA and EFSA. It is used as an anti-caking agent, emulsifier, and release agent in various food products. While purity is critical, the specific impurity limits might differ slightly from pharmaceutical grades. However, safety for human consumption is the paramount concern. Many food-grade Magnesium Stearate products are also sourced from plant-based materials, catering to allergen-conscious consumers and clean-label trends. As a reliable supplier, we ensure our food-grade Magnesium Stearate meets all necessary safety certifications.

Industrial Grade Magnesium Stearate is produced for applications where the highest levels of purity or specific pharmacopoeial certifications are not required. These grades are commonly used as mold-release agents in plastics and rubber manufacturing, as anti-caking agents in industrial powders, or as components in coatings and lubricants. While still manufactured to consistent specifications, the regulatory oversight is generally less rigorous than for pharmaceutical or food grades. Industrial grades often offer a more cost-effective solution for applications where these specific certifications are not a prerequisite. We offer competitive Magnesium Stearate prices for industrial applications, making it an accessible choice for bulk procurement.

Choosing the correct grade of Magnesium Stearate is essential for product performance, safety, and regulatory compliance.
