Description

41-Hydroxy-3,6,9,12,15,18,21,24,27,30,33,36,39-Tridecaoxahentetracontyl Stearate is a high-purity, non-ionic surfactant and emulsifier derived from stearic acid and a long-chain polyethylene glycol (PEG) derivative. This compound is valued for its excellent surface-active properties, offering a unique balance of lipophilic and hydrophilic character for stabilizing complex formulations. It is primarily utilized in the pharmaceutical, cosmetic, and specialty chemical industries where precise performance and material compatibility are critical.

Application

• Pharmaceutical Excipient: Acts as a solubilizer, emulsifier, or stabilizer in topical creams, ointments, and transdermal drug delivery systems.
• Cosmetic Formulations: Used in creams, lotions, and makeup as an effective emulsifier and texture enhancer, providing a smooth, non-greasy feel.
• Polymer Additive: Serves as an internal or external lubricant, processing aid, or anti-static agent in plastics and polymer processing.
• Industrial Lubricants & Release Agents: Functions as a component in synthetic lubricants, mold release agents, and anti-foaming formulations.
• Chemical Intermediate: Used in the synthesis of more complex specialty surfactants and functional polymers.
• Agricultural Adjuvants: Enhances the spreading and penetration of agrochemicals as a component in adjuvant blends.
