Description

6,9-Bis(Hexadecyloxymethyl)-4,7-Dioxanonane-1,2,9-Triol is a high-purity, non-ionic surfactant and specialty chemical intermediate characterized by its unique polyether-triol structure with long alkyl chains. This compound is valued for its ability to act as a versatile emulsifier, solubilizer, and viscosity modifier in complex formulations. It is primarily utilized by R&D and production teams in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel delivery systems and functional polymers.

Application

• Pharmaceutical Excipient: Used as a non-ionic surfactant in the formulation of lipid-based drug delivery systems, including self-emulsifying drug delivery systems (SEDDS) and nanoemulsions to enhance bioavailability of poorly soluble APIs.
• Agrochemical Adjuvant: Functions as an emulsifier and penetrant in pesticide and herbicide formulations, improving the spreading, adhesion, and absorption of active ingredients on plant surfaces.
• Polymer & Resin Modification: Serves as a polyol intermediate in the synthesis of specialty polyurethanes, epoxy resins, and alkyd resins, imparting flexibility, hydrophobicity, and improved compatibility.
• Lubricant & Grease Additive: Employed as a performance additive to modify viscosity, enhance thermal stability, and improve the lubricity of synthetic oils and greases.
• Cosmetic & Personal Care: Acts as an emollient and conditioning agent in high-end skincare and haircare products, providing a smooth texture and moisture retention properties.
• Industrial Cleaning: Utilized as a key surfactant in heavy-duty degreasers and industrial cleaners for its excellent emulsification power against oils and greases.
