Audited Supplier Stearic acid is one of several 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 that exists widely in nature. It has the chemical properties of general carboxylic acid. Almost all fats and oils contain stearic acid with varying content. The content of stearic acid is higher in animal fat, such as tallow. Up to 24%, the content of vegetable oil is less, tea oil is 0.8%, palm oil is 6%, but the content of cocoa butter is as high as 34%.
