Magnesium Stearate is the magnesium salt of stearic acid supplied as a fine, white hydrophobic powder. C36H70MgO4 is best known as a pharmaceutical excipient lubricant, used to prevent tablets and capsules from sticking to particles and machinery during compression & it supports consistent dosing and tablet disintegration. Magnesium distearate's hydrophobic properties also improve powder flow and enhance product uniformity. Beyond pharma, it is used in plastics and rubber as a release agent and lubricant and in cosmetics as a stabiliser and texture enhancer. Also referred to as stearic acid, octadecanoic acid magnesium salt by Magnesium Stearate supplier and manufacturer. We are the leading, trusted magnesium stearate supplier worldwide and in the United States, with reliable lead times and global supply capability.
