What Is Magnesium Stearate?
Magnesium stearate is created from the reaction of sodium stearate with magnesium sulfate. The ingredient is a solid substance that comes in powder and granule form. It's white and has a slight fatty acid odor.
Uses & Applications of Magnesium Stearate
The range of magnesium stearate uses and potential applications is broad. Magnesium stearate can act as an:
- Anti-adherent: Magnesium stearate prevents the product from having adhesion properties during production.
- Excipient: Magnesium stearate functions as an excipient and is paired with active pharmaceutical ingredients to act as a carrier, making the product easier to manufacture.
- Mold-release agent: This ingredient provides the barrier between the mold's surface and the substrate, so the product comes out of the mold easily.
- ABS/SAN internal and external lubricant: The lubricant quality of magnesium stearate helps to reduce friction and adhesion.
- De-dusting agent: Magnesium stearate helps remove dust and other fine impurities from products.
- Flow enhancer: It makes products flow easier, becoming smooth and even.
- Binder: Magnesium stearate works with other compounds so that together, they are cohesive and stable.
- Anti-caking agent: Magnesium stearate prevents lumps from forming in the product.
These qualities make magnesium stearate perfect for use in the manufacture of:
- Pharmaceutical tablets: Magnesium stearate acts as a mold release agent and excipient in tableting.
- Nutritional supplements: It is an excipient and mold release agent in the tableting process.
- Nutraceuticals: Again, the fact that the ingredient is an excipient and mold release agent in tableting helps in the manufacturing process.
- Food and beverage: Magnesium stearate brings flow enhancing, binding and anti-caking qualities to many foods and beverages.
- Rubber: It acts as a de-dusting agent as well as a lubricant in rubber production.
- Plastics: Magnesium stearate is a lubricant and de-dusting agent in plastic production.
- Personal care and cosmetics: Magnesium stearate may act as a lubricant, increase thickness or prevent emulsions from separating in cosmetic products.
Packaging & Shelf Life of Magnesium Stearate
When it's packaged in the best conditions, your supply of magnesium stearate should last its entire shelf life, which is two years from the date of manufacture.
Magnesium stearate should be kept away from sources of heat, such as sparks, open flames, hot surfaces and direct sunlight. It needs to be stored in a dry, cool and well-ventilated location. When you're not using the product, keep the container closed.
Make sure it seals well to prevent moisture from getting inside.
How to Dispose of Magnesium Stearate
