Specification: Pharmacopoeia grade
Its chemical formula is (C18H35O2)2Mg. It is a white soapy powder
with an alkaline pH. Magnesium stearate is obtained from stearic
acid, which is mostly derived from plant sources.
Its major use is in the industry as a lubricant, dusting powder,
emulsifier, binder and paint and varnish drier. Magnesium stearate
is used in the pharmaceutical drugs in order to bind tablets and
make them smooth. It is also a common additive in several foods as
it is cheaply available.
When used as an industrial binder, magnesium stearate is always
taken in lower concentrations. It is an effective binder and even
concentrations as low as 5 to 15%. Higher concentrations can cause
compaction problems. As a lubricant, it is added in the powder
blend. This is done so that the powder blend does not adhere to the
capsule or mould when it becomes compact.
Magnesium stearate is a hydrophobic substance, i.e. it has negative
affinity with water. Hence, it can be used in designing
firefighting equipment. However, it cannot be used in large
proportion as its particles may form an explosive mixture in air.
An overdose of magnesium stearate can also give off toxic fumes
resulting in asphyxia.
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. Magnesium stearate is an effective
emulsifier used in syrups, ketchups, sauces, etc. It is also used
as an anti-caking agent in preparing certain foods. Confectionaries
use magnesium stearate for binding candies, etc. Baby cosmetic
powder contains magnesium stearate as it provides a softer texture
than talcum powder.
