Description

Disodium 1-[23-(Isotridecyloxy)-3,6,9,12,15,18,21-Heptaoxatricos-1-Yl] 2-Sulphonatosuccinate is a high-performance, non-ionic/anionic hybrid surfactant engineered for demanding industrial and formulation applications. Its unique molecular structure, featuring a long polyether chain and a sulfosuccinate head group, provides exceptional wetting, emulsifying, and dispersing properties in complex aqueous systems. This compound is particularly valuable for manufacturers in the agrochemical, coatings, and textile industries who require stable, low-foaming surfactants that perform effectively under a wide range of conditions. The CAS number for this compound is 85168-80-5.

Application

• Agrochemical Formulations: Acts as a superior wetting agent and dispersant for pesticides, herbicides, and fungicides, enhancing spray coverage and system stability.
• Industrial & Institutional Cleaners: Provides effective emulsification and soil suspension in heavy-duty degreasers and alkaline cleaning formulations.
• Coatings & Inks: Used as a pigment dispersant and grinding aid in water-based paints, inks, and coatings to improve color development and prevent settling.
• Textile Processing: Facilitates dye leveling and acts as a scouring agent in pretreatment baths for fibers and fabrics.
• Polymerization: Serves as an emulsifier in the production of latex polymers, such as acrylics and styrene-butadiene rubber (SBR).
• Oilfield Chemicals: Employed in drilling muds and completion fluids for its emulsifying and anti-static properties.
