Description

3,6,9,12,15,18,21,24,27-Nonaoxahentetracontan-1-Ol is a high-purity, long-chain polyethylene glycol (PEG) derivative, specifically a PEG-9 monomethyl ether, valued for its excellent surfactant properties, solubility enhancement, and low toxicity profile. This compound is essential for formulators requiring a non-ionic, water-soluble polymer to modify viscosity, act as a solubilizer, or provide lubrication and stabilization. It is a critical raw material for industries focused on advanced chemical synthesis, pharmaceutical excipients, and high-performance personal care products.

Application

• Pharmaceutical Excipient: Used as a solubilizing agent, co-solvent, and viscosity modifier in topical formulations, ointments, and controlled-release drug delivery systems.
• Chemical Synthesis Intermediate: Serves as a versatile starting material or spacer arm for synthesizing more complex PEGylated compounds, surfactants, and specialty polymers.
• Personal Care & Cosmetics: Functions as an effective humectant, emulsifier, and skin-conditioning agent in creams, lotions, and hair care products due to its mild and non-irritating nature.
• Industrial Surfactant & Lubricant: Applied in specialty lubricants, metalworking fluids, and textile processing aids where water solubility and surface activity are required.
• Bioconjugation & Life Sciences: Utilized in the PEGylation of proteins, peptides, and other biomolecules to improve solubility, stability, and circulation time.
• Agrochemical Formulations: Acts as a wetting agent, dispersant, or adjuvant in pesticide and herbicide formulations to enhance efficacy and delivery.
