Product Description

What is Stearic Acid?

The acid is a white waxy substance. Salts and other derivatives of stearic acid are called stearates. This acid has a pungent oily smell. Stearic acid can be obtained by saponification of fats and oils. Triglycerides in oils undergo saponification under the action of hot water. The resulting mixture of compounds should be distilled to obtain the pure acid. However, stearic acid in the market is actually a mixture of stearic acid and palmitic acid. When it comes to the use of stearic acid, it is important as a surfactant and emollient due to the presence of polar head groups that can attach to metal cations. It also has non-polar chains, making it soluble in organic solvents.

Stearic acid is one of the main long-chain fatty acids that make up oils and fats. It exists in animal fats, oils and some vegetable oils in the form of glycerides. Stearic acid is obtained by hydrolysis of these oils. Stearic acid is a kind of fatty acid widely existing in nature. It has the chemical properties of general carboxylic acid. Almost all oils contain stearic acid with different content. The content of stearic acid in animal fat is higher, such as 24% in butter, less in vegetable oil, 0.8% in tea oil and 6% in palm oil, but the content in cocoa butter is higher. Up to 34%.
