Description

2-[2-[2-[2-[2-[2-[2-[2-(2-Hydroxyethoxy)ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethyl (Z)-octadec-9-enoate is a high-purity, non-ionic surfactant and emulsifying agent characterized by its long, hydrophilic polyethylene glycol (PEG) chain esterified with oleic acid. This unique structure provides excellent solubility, stability, and surface-active properties, making it a critical component in formulations requiring controlled hydrophilicity and mildness. It is essential for manufacturers in the personal care, pharmaceutical, and specialty chemical industries seeking reliable, high-performance ingredients for advanced delivery systems and stable emulsions.

Application

• Pharmaceutical Excipient: Used as a solubilizer, emulsifier, and penetration enhancer in topical creams, ointments, and transdermal drug delivery systems.
• Personal Care & Cosmetics: Serves as a primary emulsifier and stabilizer in high-end skincare products, lotions, and sunscreens due to its mildness and skin compatibility.
• Chemical Synthesis Intermediate: Acts as a versatile building block for synthesizing more complex PEGylated compounds and specialty surfactants.
• Agricultural Adjuvants: Employed in pesticide and herbicide formulations to improve wetting, spreading, and absorption on plant surfaces.
• Industrial Lubricants & Additives: Functions as a friction modifier and emulsifier in synthetic lubricants and metalworking fluids.
• Laboratory Research: Utilized in biochemical and biophysical research for membrane studies and as a non-denaturing detergent.
