Stearic acid

Stearic acid is useful as an ingredient in making candles, soaps, plastics, oil pastel, cosmetics and for softening rubber.

Stearic acid

Stearic acid emulsifies by breaking the surface tension of the items to be emulsified. The ability of stearic acid to combine water and oil with dirt make it especially useful in cleansers where the oils and water can remove dirt and build up from the skin.

Characteristics
