Description

3,6,9,12-Tetraoxaheptadecan-1-Ol is a high-purity polyether glycol derivative, specifically a tetraethylene glycol monoalkyl ether. This compound is valued for its excellent solvency properties and its role as a versatile chemical intermediate and formulation component. It is primarily sought by manufacturers in the polymer, specialty chemical, and pharmaceutical industries for applications requiring a hydrophilic, non-ionic surfactant or a reactive polyol.

Application

• Polymer & Resin Modification: Acts as a chain extender or flexibilizer in polyurethane and polyester synthesis.
• Chemical Intermediate: Serves as a key building block for synthesizing more complex surfactants, plasticizers, and specialty esters.
• Pharmaceutical Excipient: Used as a co-solvent, solubilizer, or vehicle in topical and transdermal drug delivery formulations.
• Industrial & Institutional Cleaners: Functions as a non-ionic surfactant and coupling agent in concentrated detergent systems.
• Personal Care Formulations: Employed as a humectant and viscosity modifier in creams, lotions, and cosmetic products.
• Lubricant & Metalworking Fluids: Used as an additive for its lubricity and cooling properties in synthetic and semi-synthetic fluids.
• Ink & Coating Additive: Improves flow, leveling, and pigment wetting in water-based and solvent-based systems.
