Magnesium stearate

Types

Magnesium stearate has several types. They include:

• Pharmaceutical-grade magnesium stearate

  The pharmaceutical industry prefers this grade due to its quality and purity when making medicines and supplements. Thus, it is critical in ensuring consistency and safety in drug formulation. Usually, it is synthesized through reagent-precipitation in a controlled environment. This helps in achieving the highest level of purity.

• Food-grade magnesium stearate

  The food industry uses this grade in dietary supplements and food products. Normally, this is because of its low toxicity and high quality. Usually, it acts as a lubricant and anti-adherent among other roles. For instance, Food-grade varieties must meet standards for consumption safety and are often sourced from vegetable fatty acids as opposed to animal fat.

• Industrial-grade magnesium stearate

  This grade is commonly used in non-pharmaceutical products such as cosmetics and plastics. Normally, it does not have the strict purity requirements of pharmaceutical or food grades. However, it still offers effective anti-sticking and lubricating properties in various applications. Ideally, it is often produced through the reaction of magnesium salts with stearic acid in industrial settings. This process may not always be as refined as in pharmaceutical-grade production.

• Vegetable-based magnesium stearate

  This form is made from plant-derived sources such as palm or soy oil. It is often used as an alternative to animal-based stearates. This is especially in vegetarian or vegan formulations. In addition, it provides the same functionalities with the added benefit of being suitable for vegan products.

• Micronized magnesium stearate

  This stearate is produced by micronization processes. They include milling or high-energy planetary ball milling. This process reduces the particle size to the micrometer range. Normally, the small particle size enhances lubrication properties due to increased surface area. Thus, it is particularly useful in high-potency formulations where uniformity of mixture is critical.
