Description

26-(Octylphenoxy)-3,6,9,12,15,18,21,24-Octaoxahexacosanoic Acid is a high-purity, non-ionic surfactant and specialty chemical intermediate characterized by its unique polyether chain and terminal carboxylic acid group. This molecular structure provides excellent surface-active properties, making it a critical component for formulating stable emulsions and dispersions. It is primarily utilized in advanced industrial applications such as polymer synthesis, agrochemical formulations, and specialty coatings where precise performance modifiers are required.

Application

• As a non-ionic surfactant and emulsifier in agrochemical formulations (herbicides, pesticides, fungicides).
• As a functional monomer or macromonomer in the synthesis of specialty polymers and resins.
• As a dispersing agent and stabilizer in pigment pastes, inks, and advanced coating systems.
• As a intermediate for further chemical modification, leveraging its reactive carboxylic acid group.
• As an additive in lubricants and metalworking fluids to enhance surface wetting and stability.
• In the research and development of novel amphiphilic compounds for pharmaceutical and cosmetic applications.
