What is stearic acid used for?

It gives hardness and strength to soap and candles. Despite the fact that the hardness of stearin exceeds the hardness of paraffin, it is a mandatory additive in those candles that burn for a long time. Most often it is added to paraffin in a ratio of one to ten. Candles to which stearin is added are easily removed from molds during manufacture.

If you add stearic acid to soap, it becomes hard, foams well and has a pleasant matte surface. Stearic acid is a popular thickener and emulsifier in the production of various cosmetics.

Most often, the amount of stearic acid in creams is no more than five percent, and in soap - no more than twenty-five percent.
