FAQ

What is Lead Stearate (CAS: 1072-35-1)?

Lead Stearate (CAS: 1072-35-1) is a white, waxy solid composed of lead and stearic acid. Its chemical formula is Pb(C₁₈H₃₅O₂)₂, making it a lead(II) salt with a molecular weight of approximately 720.55 g/mol. It is insoluble in water, has a high melting point, and is commonly used as a stabilizer and lubricant in industrial applications. As a heavy metal compound, it requires careful handling due to potential toxicity.

What are the main uses of Lead Stearate (CAS: 1072-35-1)?

Lead Stearate (CAS: 1072-35-1) is primarily used as a stabilizer in polyvinyl chloride (PVC) products, enhancing heat and light resistance. It also serves as a lubricant in pharmaceutical tablet coatings and industrial manufacturing. Additionally, it is employed in the production of rubber, plastics, and as a pigment in some applications. However, its use in food or pharmaceuticals is restricted due to health risks associated with lead exposure.

Is Lead Stearate (CAS: 1072-35-1) safe?

Lead Stearate (CAS: 1072-35-1) is not considered safe for direct human contact due to its lead content. It is classified as a toxic substance and can pose risks through inhalation, ingestion, or skin absorption. Safety standards require proper protective measures, such as gloves and ventilation, during handling. Its use in food or pharmaceuticals is generally prohibited, but it may be used in industrial settings with strict safety protocols.

How should Lead Stearate (CAS: 1072-35-1) be stored?

Lead Stearate (CAS: 1072-35-1) should be stored in a cool, dry place, away from moisture and light. Keep it in a tightly sealed container to prevent exposure to air. It is stable under normal storage conditions but must be stored separately from incompatible materials. Always ensure proper labeling and follow safety guidelines to avoid contamination or degradation.
