Description

Hexanoic Acid, 2-Ethyl-, 44-Hydroxy-3,6,9,12,15,18,21,24,27,30,33,36,39,42-Tetradecaoxatetratetracont-1-Yl Ester is a specialized polyethylene glycol (PEG) ester derivative of 2-ethylhexanoic acid, designed to impart amphiphilic properties and enhanced solubility. This compound is valued for its role as a versatile non-ionic surfactant, solubilizer, and coupling agent in advanced formulations. It is primarily needed by manufacturers in the pharmaceutical, personal care, and specialty chemical industries for creating stable emulsions and improving the bioavailability of active ingredients.

Application

• Pharmaceutical Excipient: Used as a solubilizer and bioavailability enhancer for poorly water-soluble active pharmaceutical ingredients (APIs) in oral and topical formulations.
• Personal Care & Cosmetics: Functions as a non-ionic surfactant and emulsifier in creams, lotions, and serums, providing stable texture and improved skin feel.
• Polymer & Resin Modification: Acts as a plasticizer, lubricant, or compatibilizer in polymer processing and specialty resin systems.
• Agrochemical Formulations: Employed as an adjuvant and emulsifier in pesticide and herbicide concentrates to enhance spreading and penetration.
• Industrial & Institutional Cleaners: Serves as a surfactant and coupling agent in concentrated cleaning solutions and degreasers.
• Chemical Synthesis Intermediate: Utilized as a building block for synthesizing more complex PEGylated compounds and specialty esters.

Quality Control

Our Hexanoic Acid, 2-Ethyl-, PEG Ester is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with relevant pharmaceutical and industrial standards. Key parameters such as ester content, hydroxyl value, acid value, and polyethylene glycol (PEG) distribution are monitored. Certificates of Analysis (COA) documenting purity, identity, and key physical properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture.
