What is Magnesium Stearate Powder?

Magnesium Stearate is a finely textured, white powder that serves as a crucial functional excipient in industrial manufacturing. Its chemical formula is C₃₆H₇₀MgO₄, and it is the magnesium salt of stearic acid. This compound is renowned for its excellent lubricating properties.

In production processes, it is primarily used to prevent ingredients from sticking to manufacturing equipment during compression and encapsulation. This makes Magnesium Stearate for tablets and capsules an indispensable ingredient, ensuring high production efficiency and consistent product quality for B2B clients.

The Efficacy of Magnesium Stearate

As a key manufacturing aid, Magnesium Stearate Powder offers several critical functions:

Superior Lubrication: It significantly reduces friction between the powder blend and the metal surfaces of tablet punches and dies, preventing sticking and ensuring smooth, continuous production runs with minimal downtime.
Effective Anti-Adhesion: This property prevents powdered formulations from clinging to machinery and other particles, which is vital for maintaining the uniformity and structural integrity of the final product, such as supplements or pharmaceutical tablets.
Enhanced Flowability: By reducing inter-particle friction, the powder blend flows more freely and consistently into tablet presses or capsule filling machines, leading to more accurate dosing and uniform weight control.
Promoting Tablet Disintegration: While it acts as a lubricant, when used at optimal concentrations, it still allows the finished tablet to break apart effectively upon ingestion, ensuring the bioavailability of the active ingredients.

How We Ensure Premium Quality

At Oclean Nutra, our commitment to quality is paramount. Our high purity Magnesium Stearate Powder is produced and handled under strict quality control protocols. Every batch is rigorously tested to meet stringent specifications.

FAQs

What is the primary function of Magnesium Stearate in supplement manufacturing?

The primary function of Magnesium Stearate in supplement manufacturing is to act as a lubricant and anti-adherent. It ensures that powder blends flow smoothly and do not stick to the tablet presses and capsule filling machines during high-speed production. This is critical for achieving consistent tablet weight, shape, and structural integrity, while also minimizing equipment wear and production downtime.

Can you supply a Certificate of Analysis (COA) for each batch?

Yes, we provide a comprehensive, batch-specific Certificate of Analysis (COA) for all our B2B clients. This is a standard part of our quality assurance process. The COA provides detailed analytical results for all key parameters, ensuring full transparency and traceability. You can request a sample COA here.

What is your typical lead time for bulk orders?

Our typical lead time for bulk orders is 5 to 10 working days after order confirmation. We maintain strategic stock levels and efficient logistics to meet this commitment. For custom requirements or exceptionally large volumes, we will provide a specific and confirmed timeline during the order process.

Is your Magnesium Stearate suitable for vegan and halal products?

Absolutely. Our vegetable-based Magnesium Stearate is derived solely from plant sources and is not of animal origin. This makes it entirely suitable for vegan, vegetarian, and halal-certified product formulations, which is a key requirement for many of our global B2B partners.

Do you offer technical support for product formulation?

Yes, we provide technical data and support to assist our B2B clients with their formulation challenges. Our team can share insights on the optimal usage levels of Magnesium Stearate for tablets and capsules to achieve the best balance between lubrication and product disintegration.
