Stearates

A saturated fatty acid with an 18-carbon chain is stearic acid. Octadecanoic acid is known by its IUPAC name. Its chemical composition is C17H35CO2H, and it is a waxy solid. Its name is a translation of a Greek word that signifies tallow. Stearates are the names for stearic acid salts and esters. Stearic acid, which serves as its ester, is the second most prevalent saturated fatty acid found in nature after palmitic acid. Stearin is the triglyceride formed from three molecules of stearic acid.

Stearates are stearic acid salts or esters. Stearate are typically created during the saponification processes, in which soaps are made by processing fats with strong bases. Stearate feature both hydrophilic and hydrophobic areas, allowing them to function as surfactants. Animal fat contains more stearic acid than vegetable fat, which typically contains less than five percent. The foods cocoa butter and shea butter, which contain stearic acid, are the significant exceptions.

In terms of its biosynthesis, acetyl-CoA gives two-carbon building blocks to the fatty acid production mechanism, which converts carbs into stearic acid. The triglycerides in fats and oils are saponified using hot water to produce stearic acid. After that, the resultant mixture is distilled. Although pure stearic acid is accessible, commercial stearic acid is frequently a blend of stearic and palmitic acids. Commercially, oleic acid can be transformed into stearic acid by hydrogenating oleic acid-rich fats like palm and soy.

The most efficient stabilizer for polymers, particularly for PVC and its associated products to generate good initial color and clarity as well as to retard the degradation against heat and UV, is cadmium organic salts, commercially known as Cadmium Stearate or Cadmium Laurate. These stabilizers enable processing at high temperatures. Applications involving food packaging are prohibited for these substances. However, they are not substituted with an equivalently effective alternative stabilizer for exterior applications including profiles, pipes, hoses, and electrical insulation.
