Description

Oxirane, Methyl-, Polymer With Oxirane, Didodecylbenzenesulfonate is a high-performance, nonionic surfactant and emulsifier derived from a block copolymer of ethylene oxide and propylene oxide, terminated with a didodecylbenzenesulfonate group. This unique structure provides exceptional wetting, dispersing, and stabilizing properties in demanding formulations. It is a critical additive for industries requiring robust surface activity and compatibility with various chemical systems, particularly where controlled rheology and stability are paramount.

Application

• Industrial & Institutional Cleaners: Acts as a powerful surfactant and wetting agent in heavy-duty degreasers, metal cleaners, and floor care products.
• Coatings & Inks: Functions as a dispersant and flow control agent in pigment preparations, water-based paints, and printing inks to prevent settling and improve gloss.
• Agrochemical Formulations: Used as an emulsifier and stabilizer in pesticide and herbicide concentrates to ensure stable emulsions upon dilution.
• Textile Processing: Serves as a leveling agent, lubricant, and antistatic agent in fiber production and fabric finishing.
• Polymer & Resin Production: Employed as an internal or external lubricant and processing aid to improve mold release and surface finish.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals as a demulsifier and viscosity modifier.
