Description

Hexanoic Acid, 2-Ethyl-, 41-Hydroxy-3,6,9,12,15,18,21,24,27,30,33,36,39-Tridecaoxahentetracont-1-Yl Ester is a specialized polyethylene glycol (PEG) ester derivative of 2-ethylhexanoic acid, designed to impart unique surfactant and solubilizing properties. This compound matters for its ability to act as a non-ionic surfactant, emulsifier, and coupling agent in complex formulations, enhancing compatibility between hydrophobic and hydrophilic components. It is primarily needed by manufacturers in the personal care, pharmaceutical, and specialty chemical industries for advanced product development.

Application

• Personal Care & Cosmetics: Used as an emulsifier, solubilizer, and skin-conditioning agent in creams, lotions, and sunscreens.
• Pharmaceutical Formulations: Serves as a solubilizing excipient for poorly soluble active pharmaceutical ingredients (APIs) and in topical drug delivery systems.
• Industrial Surfactants: Functions as a wetting agent, dispersant, and coupling agent in coatings, inks, and agrochemical formulations.
• Polymer & Resin Modification: Acts as a plasticizer, lubricant, or processing aid in polymer production and modification.
• Cleaning & Detergent Formulations: Employed as a non-ionic surfactant in industrial and institutional cleaning products.
• Chemical Synthesis: Utilized as an intermediate or building block for synthesizing more complex PEGylated compounds.
