Description

29-[2,4-Bis(1,1-Dimethylethyl)Phenoxy]-3,6,9,12,15,18,21,24,27-Nonaoxanonacosan-1-Ol is a high-purity, non-ionic surfactant and specialty chemical intermediate designed for advanced formulation chemistry. This compound matters because its unique structure, featuring a bulky hindered phenol group linked to a long polyethylene glycol (PEG) chain, provides excellent steric stabilization and compatibility in complex systems. It is primarily needed by manufacturers in the polymer, coatings, and specialty chemical industries seeking to enhance product performance and stability.

Application

• Polymer Additive: Acts as a steric stabilizer and antioxidant in polymerization processes, particularly for vinyl and acrylic monomers.
• Coatings & Inks: Used as a dispersing agent and flow modifier to improve pigment wetting and prevent settling in high-performance coatings and printing inks.
• Lubricant & Grease Formulation: Serves as a key component in synthetic lubricants and high-temperature greases, offering thermal stability and anti-wear properties.
• Pharmaceutical & Cosmetic Excipient: Functions as a non-ionic solubilizer and emulsifier for active ingredients in topical formulations and drug delivery systems.
• Adhesive & Sealant Production: Enhances the compatibility and rheological properties of epoxy, polyurethane, and silicone-based adhesives.
• Chemical Intermediate: Utilized in the synthesis of more complex surfactants and functional polymers due to its reactive terminal hydroxyl group.
