General description:
Stearic acid chemicals known as octadecanoic acid is one of the most common and useful type of saturated fatty acids found in combined form in natural animal and vegetable fats. Esters and salts of stearic acid are known as stearate. Stearic Acid found commercially is a mixture of approximately equal amounts of stearic and palmitic acids and small amounts of oleic acid. Naturally stearic acid occurs as a mixed triglyceride, or fat, with other long-chain acids and as an ester of a fatty alcohol. It is found abundantly in animal fat than in vegetable fat.
Application & Usage:
Stearic acid is a very effective wax modifier used in candle making. Stearic acid acts as a thickener or hardener to help the soap to retain its shape. It is a powerful cleanser and also acts as an emulsifying agent to bind oil and water.
