Metallic stearates are one of the great hidden cross-industry chemistries, and Peter Greven sits across the whole span. The same family of metal soaps it makes serves: magnesium stearate as a tablet lubricant in pharmaceuticals AND as the binder that holds pressed-powder cosmetics together (eyeshadow, blush, compact powder); calcium and zinc stearates as heat stabilizers and lubricants in PVC pipe and window profiles and as acid scavengers in polyolefin plastics; calcium stearate as a water-repellent in gypsum wallboard and concrete; and lithium stearate as the thickener that turns base oil into lithium grease — the most common grease in the world, used in the very bearings other parts of this radar track. One oleochemical maker therefore sits beneath medicine, makeup, plastics, building materials and lubricating grease simultaneously.

If microcrystalline cellulose gives a tablet its body, magnesium stearate is what lets the tablet exist at all: it is the lubricant that keeps compressed powder from sticking to the press tooling, present in the overwhelming majority of tablets and capsules. Peter Greven is one of the leading global makers of this metallic stearate. So the inert backbone of most pills comes down to two ubiquitous excipients from a short list of specialists — MCC (JRS, DuPont/IFF) and magnesium stearate (Peter Greven and peers). The active drug is the headline; the pill only physically exists because of a cellulose fiber and a metal soap from a handful of European chemical houses.
