Let’s face it—sourcing stearates isn’t glamorous. But getting the wrong material, or getting it too late, causes real headaches.

All stearates are not created equal. If you’re using them in plastics, rubber, coatings, food, or pharmaceuticals, the type you choose can make or break your process.

Global supply chains are still unpredictable. Freight prices bounce. Raw material shortages flare up. And when it comes to chemical ingredients, any delay in sourcing the right one—like a stearate—can grind production to a halt.
