In pharmaceutical dosage forms, stearic acid is used as an emulsifying agent, solubilizing agent, tablet and capsule lubricant. It is also commonly found in lotions, detergents, soaps, and shampoos, and is a natural component of cocoa butter and shea butter. Stearic acid use as an inactive ingredient must be approved by the FDA. Magnesium stearate is the chemical compound with the formula Mg(C 18 H 35 O 2) 2.It is a soap, consisting of salt containing two equivalents of stearate (the anion of stearic acid) and one magnesium cation (Mg 2+).Magnesium stearate is a white, water-insoluble powder. Its applications exploit its softness, insolubility in many solvents, and low toxicity. Magnesium stearate is a white powder that combines the essential mineral magnesium and the saturated fat stearic acid. Manufacturers use magnesium stearate in some supplements and medications as an inactive ingredient to help keep the active ingredients flowing smoothly through the machinery used to produce the supplements3.
But shape is only one of the properties that stearic acid adds to cleansers such as bar soaps and body washes.

(5) The term “stearate” is used when stearic acid is part of a salt (as when stearic acid combines with magnesium to form magnesium stearate). The terms stearic acid and stearate can be used interchangeably. The presence of stearic acid improves the floating behavior for more than 8 hours. The hydration volume, the tablet hardness and the ejection pressure decrease as the stearic acid content increases and the polymer content decreases. Drug dissolution increases with increasing proportions of stearic acid and decreasing proportions of the polymer ...

Magnesium stearate is a synthetic chemical not found in nature. Each molecule is made of the mineral magnesium, along with two chains of stearate attached. Stearate is the negatively charged ion (anion) of stearic acid, a type of saturated fat. The magnesium may come from mining while the stearic acid may be from fatty vegetables, meat, or dairy.

These fatty acids are absorbed, digested, and transported in
Stearic acid is ideal because of its natural source. It doesn't interfere with the proper utilization or absorption of the active ingredients in the tablet. There’s no evidence that stearic acid, in the amounts used in tablets, interferes with the absorption or utilization of nutrients. The use information is displayed per substance life cycle stage (consumer use, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites or in manufacturing). The information is aggregated from the data coming from REACH substance registrations provided by industry.
Magnesium stearate, which is a salt that contains magnesium and stearic acid, is used as a flow agent in supplements. Studies suggest that stearic acid suppresses immune cells called T cells. This NutriNeat write-up provides more information on the uses and side effects of stearic acid.
