Magnesium stearate Descrption

Magnesium stearate is a white substance that has two equivalents of stearate and one magnesium cation. It is safe for human consumption. It is often used as a filling agent in the manufacture of supplement capsules. This substance has lubricating properties and prevents ingredients from sticking to manufacturing equipment during the compression of chemical powders into capsules or tablets. Most pharmaceutical formulations include a certain amount of lubricant to improve their flowability and prevent their adhesion to the surfaces of processing equipment.

Magnesium stearate Application

Magnesium Stearate is a popular lubricant because it also acts as a glidant and anti-adherent.Magnesium stearate is often used as an anti-adherent in the manufacture of medical tablets, capsules and powders.In this regard, the substance is also useful, because it has lubricating properties, preventing ingredients from sticking to manufacturing equipment during the compression of chemical powders into solid tablets; magnesium stearate is the most commonly used lubricant for tablets.Magnesium stearate can also be used efficiently in dry coating processes.

Magnesium stearate is used in the pharmaceutical drugs in order to bind tablets and make them smooth as well as shinier. Magnesium stearate has been graded to be a safe chemical compound, with no side effects known. Several foods use magnesium stearate as an additive or preservative.

How to Use Magnesium stearate

Magnesium stearate is typically used in a concentration range of 0.25%-2%. Higher values can result in decreased absorption of the product. We consequently limit magnesium stearate concentrations in our formulations to 1% or less. Whenever possible, we encourage our manufacturers instead to utilize silica and magnesium trisilicate at slightly higher levels in order to obtain the necessary lubricating/glidant effects. In most capsule formulations this works well. However, in tablet manufacture it is generally necessary to use magnesium stearate at the 1% concentration in order to enable tablet release from molds. In a few cases where an encapsulated product is greatly hydroscopic (i.e., water-absorbing) (such as l-carnosine and acetyl-l-carnitine), it is necessary to utilize up to 1% magnesium stearate in order to block excess moisture uptake leading to poor or uneven capsule filling.
