They are fatty acids that make up stearin. Store in a cool, dry, and ventilated place. Sources of ignition and oxidizers. Stearic acid is a kind of fatty acid that exists widely in nature. Almost all oils have stearic acid with varying content. The content in animal fat is relatively high. For example, the content in tallow can reach 24%, medium content is less, tea oil is 0.8%, and 6%, but the content of medium is as high as 34%. The production methods of industrial stearic acid mainly include fractionation and pressing. Add a decomposing agent in the medium, then hydrolyze to get crude fatty acid, and then wash, decolorize and get the finished product, and at the same time, the by-product, stearic acid will produce harmful gas when it is produced again.
