Magnesium myristate

Magnesium myristate (CAS 4086-70-8), also known as magnesium tetradecanoate, is a magnesium salt of myristic acid used across pharmaceuticals, personal care, and polymer processing.

It functions primarily as a lubricant, flow modifier, and plasticizer in solid and semi-solid systems. In pharmaceutical tablet manufacturing, it acts as a die-wall lubricant that reduces ejection force.

This material prevents sticking without significantly retarding dissolution. Personal care formulators incorporate it into pressed powders, foundations, and loose cosmetic powders to improve slip and adhesion.

It enhances texture on skin and provides a smooth application. In polymer compounding, it serves as an internal lubricant and processing aid that reduces melt viscosity during manufacturing.

The additive improves surface finish in extruded or molded parts. It is also used in specialty coatings and wax-based systems where controlled rheology and softening behavior are required.

Magnesium myristate is supplied as a fine white powder, the standard form for both pharmaceutical and cosmetic applications. It is available in pharmaceutical-grade and cosmetic-grade specifications.

The pharmaceutical supply typically aligns to excipient standards relevant to tablet formulation. Bulk quantities are offered in fiber drums or multi-wall bags suited to industrial procurement.
