Tristearin

Tristearin is a triglyceride derived from three units of stearic acid. Most commonly found in animal and vegetable fats, tristearin is a solid substance at room temperature and is considered a saturated fat.

Chemical Structure

Tristearin, also known as glyceryl tristearate, is a glycerol ester of stearic acid. Its chemical formula is C57H110O6. The molecule is formed by the esterification of three stearic acid molecules with one glycerol molecule.

Properties

Tristearin is a white, waxy solid at room temperature. It is insoluble in water but soluble in organic solvents such as ethanol and chloroform. It has a high melting point, typically around 72-75 degrees Celsius.

Uses

Tristearin is used in a variety of applications. In the food industry, it is used as a stabilizer and thickener. In cosmetics, it is used as an emollient and to give products a creamy texture. It is also used in the production of soaps and detergents due to its ability to harden soaps and increase their melting point.

Health Effects

As a saturated fat, tristearin can contribute to increased levels of cholesterol in the blood if consumed in large amounts. However, it is generally considered safe for use in food and cosmetics.
