UNIPURE MS (MAGNESIUM STEARATE)
GENERAL INFORMATION
UNIPURE MS is a fine, white, odorless, and tasteless powder derived from the reaction of magnesium with stearic acid. It is insoluble in water but slightly soluble in alcohol. It is commonly used to enhance powder flowability, reduce friction during tablet manufacturing, and improve surface characteristics in various formulations.
PRODUCT DESCRIPTION
Magnesium stearate (Mg(C18H35O2)₂) is a magnesium salt of stearic acid, widely used as a lubricant and binder in pharmaceutical tablet and capsule production. It is non-hygroscopic and ensures smooth tablet compression with uniform release properties.
