Kemsurf OT70-KE

Product Category: Anionics

Sodium Dioctyl Sulphosuccinate - Hydrocarbon Fluid

INCI Name: Sodium Dioctyl Sulphosuccinate

Quick Links

Kemsurf OT70-KE is an anionic surfactant based on sodium dioctyl sulphosuccinate, supplied as a solution in hydrocarbon fluid.


The hydrocarbon solvent carrier provides direct compatibility with oil-phase and solvent-based systems, eliminating the need for additional co-solvents when formulating in non-aqueous media. This makes Kemsurf OT70-KE particularly suitable for applications where water or glycol-based carriers are undesirable.


Kemsurf OT70-KE retains the excellent wetting, emulsification and dispersing properties characteristic of sodium dioctyl sulphosuccinate, while offering enhanced ease of incorporation into hydrocarbon-based formulations. It is widely used in solvent-based coatings, agrochemical formulations, oil-phase systems and industrial applications where effective wetting and emulsification are required in non-aqueous environments.

​

Key Features

 

  • Direct Compatibility with Oil-Phase Systems - Supplied in a hydrocarbon fluid carrier, Kemsurf OT70-KE can be incorporated directly into solvent-based and oil-phase formulations without the need for additional co-solvents or coupling agents.

  • Excellent Wetting & Emulsification Performance - As a high-active anionic surfactant (~70% surface active matter), Kemsurf OT70-KE delivers rapid wetting, effective emulsification and strong dispersing performance in non-aqueous systems.

  • Versatile Industrial Applicability - Kemsurf OT70-KE is suitable for use across a wide range of applications including solvent-based coatings, agrochemical formulations, metalworking fluids and industrial cleaning systems where water-based carriers are undesirable..
