stannous stearate

Description:
Stannous stearate, with the CAS number 6994-59-8, is a chemical compound that consists of tin (Sn) in its +2 oxidation state, complexed with stearic acid, a long-chain fatty acid. This compound typically appears as a white to off-white powder and is known for its role as a stabilizer and lubricant in various applications, particularly in plastics and rubber manufacturing. Stannous stearate exhibits good thermal stability and is soluble in organic solvents, making it useful in formulations requiring enhanced processing characteristics. Additionally, it can act as a catalyst in certain polymerization reactions. The compound is generally considered to have low toxicity, but like many organotin compounds, it should be handled with care due to potential environmental and health concerns associated with tin compounds. Its applications extend to the food industry, where it may be used in food packaging materials, although regulatory guidelines must be followed to ensure safety. Overall, stannous stearate is valued for its multifunctional properties in industrial applications.
