FAQ

What is Sorbitan Monostearate (CAS: 1338-41-6)?

Sorbitan Monostearate (CAS: 1338-41-6) is a synthetic emulsifier and surfactant derived from sorbitol and stearic acid. It appears as a white, waxy powder and is insoluble in water. Commonly used in pharmaceuticals, food, and industrial applications, it stabilizes mixtures and reduces surface tension. Its chemical formula is C20H42O6, and it is classified as a non-ionic surfactant with hydrophilic-lipophilic balance (HLB) properties.

What are the main uses of Sorbitan Monostearate (CAS: 1338-41-6)?

Sorbitan Monostearate (CAS: 1338-41-6) is widely used as an emulsifier in pharmaceuticals to blend oil and water-based ingredients. In the food industry, it acts as a stabilizer in dairy products, confections, and baked goods. It also serves as a lubricant in cosmetics and industrial applications. Additionally, it is employed in research for developing emulsified formulations and as a wetting agent in various chemical processes.

Is Sorbitan Monostearate (CAS: 1338-41-6) safe?

Sorbitan Monostearate (CAS: 1338-41-6) is generally recognized as safe (GRAS) by regulatory bodies when used in approved concentrations. It has low toxicity and is non-hazardous under normal handling conditions. However, direct ingestion should be avoided, and proper protective equipment is recommended during handling. Safety standards ensure its use in food, pharmaceutical, and industrial contexts adheres to strict guidelines.

How should Sorbitan Monostearate (CAS: 1338-41-6) be stored?

Sorbitan Monostearate (CAS: 1338-41-6) should be stored in a cool, dry place away from direct light and moisture. Keep in a sealed, airtight container to prevent contamination and maintain stability. It is chemically stable under these conditions but should be protected from high temperatures and humidity to avoid degradation or clumping.
