Origin
Stearic acid is obtained by the hydrolysis of common vegetable and animal oils and fats. The resulting fatty acids then undergo crystallization or distillation. There are certain pressing methods that are used to separate the solid saturated fatty acids from the liquid unsaturated fatty acids. Cosmetic-grade Stearic acids are generally pressed two or three times to obtain different concentrations.

Lotions and Face Creams
When added to lotion formulations, Stearic Acid functions as a thickening agent that contributes a richness to the texture of the final product. Recommended Usage for Lotions and Creams: 2-5%.
Candles
When added to recipes for paraffin candles, Stearic Acid functions as a hardener. The harder the wax, the longer it will take the flame to melt it, thus resulting in a longer-lasting candle. Because Stearic Acid causes wax to shrink as it cools down, it also enables the easy release of the final product from a mold. Furthermore, its opacifying properties help to boost the colors of added dyes. Being a fragrance ingredient, Stearic Acid’s fat cells attach to the scent of an added aroma and prevents it from seeping out of the candle, which allows the fragrance to last longer. Recommended Usage for Candles: 3-5%
