CAS Number9004-99-3

CategorySurfactants & Emulsifiers

Description Polyoxyl 40 Stearate, Type II, is a nonionic surfactant commonly used as a pharmaceutical excipient due to its emulsifying, solubilizing, and dispersing properties. It functions by reducing the surface tension between ingredients, which facilitates the uniform distribution of active pharmaceutical ingredients (APIs) within a formulation. This makes it particularly valuable in the development of oral, topical, and parenteral dosage forms. As an emulsifier, it aids in the stabilization of oil-in-water emulsions, ensuring that lipid-based drugs are adequately solubilized. Additionally, Polyoxyl 40 Stearate, Type II, enhances the bioavailability of poorly water-soluble drugs by improving their dissolution profile, thereby enabling more efficient drug delivery and absorption. Its versatile utility in improving the consistency and effectiveness of pharmaceutical products makes it an essential component in various drug formulation processes.
