    Sodium Di(2-ethylhexyl) Sulfosuccinate OT-75 CAS 577-11-7

    Sodium Di(2-ethylhexyl) Sulfosuccinate (OT-75) is an anionic sulfosuccinate surfactant used as an industrial ingredient in chemical formulation systems. Identified by CAS No. 577-11-7, this material functions through sulfonate-driven surface activity, enabling rapid wetting, interfacial tension reduction, and dispersion within liquid-based systems. It is commonly applied in surfactant formulations where controlled wetting and emulsification behavior are required in industrial processing. Supply is provided with competitive factory pricing, supports customized specifications, and includes MSDS, TDS, COA documentation for bulk supply.

    Product Description

    Product Overview

    Sodium Di(2-ethylhexyl) Sulfosuccinate OT-75 is best positioned as a functional additive / specialty chemical rather than a terminal consumer product. Based on its product identity and application profile, this material is supplied as a high-efficiency anionic surfactant for systems requiring rapid wetting, penetration and interfacial tension reduction.

    It is commonly applied in textile processing, agrochemical formulations, paper chemicals and related industrial liquid systems where strong surface activity and dispersion support are required. OT-75 generally indicates a formulated supply grade rather than a pure solid substance, so appearance and handling properties should be confirmed against the supplied specification.

    For product evaluation, concentration, appearance, packaging and compatibility with the intended system should be checked according to the supplied grade.
