Magnesium stearate is a fine white powder. Its main purpose is providing a lubricant for capsules and tablets. It increases flowability, which ensures efficiency through the manufacturing process.

Magnesium stearate is one of the most popular flowing agents in the industry. It is popular due to how effective it is as a dry lubricant. It is inert and can make your formulation process much easier.

Magnesium stearate is a magnesium salt that also has stearic acid. Stearic acid is an 18 carbon long saturated fat that is often found in food. Stearates represent a natural part of every single kind of fat from animal to vegetable. It is a common fatty acid that can be found in fish, grains, eggs, butter, poultry, meat and dairy products. In meat, it is one-third of the saturated fat. This is important for consumer familiarity. It also portrays the safety of this ingredient. It is not something that is new to the human body. It adds an element of safety to your product.

Lubricants are crucial in tableting. This is why magnesium stearate is so commonly used. The purpose of a lubricant is to improve specific processing benefits. There are three important roles of a lubricant.

  • To lessen friction at the junction between a tablets surface and the die wall during ejection. This will reduce wear on the tablets.
  • To prevent the solution from sticking to the parts of a machine that it is currently running through.
  • To increase flow by reducing friction amongst the particles themselves.

An excellent lubricant will form a strong layer over the surface. Another positive factor is that it is adverse to a change in process variables. Process variables are a dynamic part of the process that can change in a given way. This will generally be flow, pressure and temperature. If any of these changes occur, it shouldn't affect the manufacturing process.

Magnesium is an important part of health. As an essential mineral it is often missing from the human diet despite the many places it is found. It helps to keep blood sugar and blood pressure at the right levels. It helps form DNA and protein, and keeps muscles and nerves functioning correctly. Women need 320 milligrams daily whilst men need 420 milligrams daily for excellent health.

Magnesium stearate is:-

  • "GRAS" (Generally Recognized As Safe) listed
  • Designated as a food additive in Europe
  • Manufactured from vegetables oils, most commonly palm oil and cottonseed oil.

Stearates can be manufactured through hydrogenation (treatment with hydrogen). The result of this process is a product that should be handled properly.

Magnesium stearate cannot be mixed with air as dust explosion can occur. It should be kept away from flames at all costs. If it is dry, it can be charged electrostatically by swirling and pouring among other actions. If inhaled it can cause coughing and if ingested, vomiting may occur. Use protective gloves, safety goggles and a mask while handling this product.

The chemical formula of magnesium stearate is Mg(C18H35O2). Other names for magnesium stearate are octadecanoic acid and magnesium salt.

This product is generally the top choice as a dry lubricant. Additionally, as a mineral comfortable in the human body it can be consumed safely on a regular basis. It might be the perfect excipient for your product.
