Stearates

Mallinckrodt Pharmaceuticals (SpecGx LLC) is the world leader in the production of high-quality, reliably performing stearates for the pharmaceutical, nutraceutical, and food industries. Their stearates have been manufactured at their cGMP plant in St. Louis, MO for over a century using a unique water-based precipitation process to yield a consistent, “platelet-like” particle that is considered a true monohydrate. High purity pharmaceutical grade stearates are offered with the DMF to support your formulation work and food grade stearates are available with kosher, halal, and RSPO mass balance certifications. Mallinckrodt goes above and beyond global compendia requirements to ensure consistent performance by controlling additional physical parameters such as surface area, particle size, and bulk density. The result is measurably better stearates that provide better powder flowability and blend uniformity while avoiding capping, lamination, pitting, and sticking in tablets.

Product highlight: Stear-O-Wet™

Stear-O-Wet™ is a spray-dried mixture of magnesium stearate and sodium lauryl sulfate. The addition of the sodium lauryl sulfate surfactant makes this product a hydrophilic magnesium stearate, reducing the uncertainty of attempting to dry blend the two in a consistent, homogeneous manner. Wettable formulations improve disintegration and dissolution of drug substances in tablets and are particularly useful in formulations with solubility issues. As such, Stear-O-Wet™ streamlines the supply chain in that manufacturers only need to source and stock one co-processed excipient instead of two separate ingredients.  Stear-O-Wet™ is uniform, avoiding the potential issue of over-blending if added separately, which can slow the rate of active ingredient dissolution due to the hydrophobic nature of magnesium stearate.
