Stearic Acid is a fatty acid found primarily in animal derivatives, but in vegetable fats as well. It is used in a variety of cosmetics and personal care products, as a fragrance ingredient, surfactant and emulsifier. It is also used as the base for the manufacture of other fatty acid ingredients which are used as emulsifers, emollients and lubricants, It is also used as an ingredient in candles, plastics, dietary supplements, oil pastels, and for softening rubber; it is a frequent ingredient in soaps made from vegetable oil, and is used to harden the product (Wikipedia).

Why use Stearic Acid?

Stearic acid is a waxy oil fraction that acts as a lubricant to fill capsules when a dry powdered ingredient (or ingredient mix) is uncooperative, based on issues involving density, stickiness, flowability under pressure, etc. It is also used as an ingredient that helps tablets hold together and break apart properly.
