Sodium dioctyl sulfosuccinate

Sodium dioctyl sulfosuccinate (CAS 1639-66-3 ), also known as sodium diethylhexyl sulfosuccinate, is an anionic surfactant used across industrial and specialty formulations.

It functions primarily as a wetting agent, emulsifier, and dispersant, enabling uniform mixing of oil and water phases in systems where conventional surfactants underperform.

In agricultural formulations, it improves the spreading and penetration of pesticide and herbicide concentrates, ensuring even coverage on treated surfaces during application.

Personal care and cosmetic manufacturers incorporate it into cleansing products and emulsions where controlled foam and stable dispersion are required for high-quality results.

Textile and leather processing operations use it to enhance dye penetration and improve wetting of fiber substrates during treatment baths to ensure consistent color and finish.

In printing and packaging, it acts as a dispersant and wetting agent in ink and coating formulations to promote substrate adhesion and pigment uniformity across various materials.

Sodium dioctyl sulfosuccinate is supplied as a liquid solution, typically at concentrations of 70–75% active content, though solid forms are available for specific industrial applications.

Technical and food-grade specifications are the most commonly sourced, with food-grade material meeting FCC standards for use in regulated applications and sensitive formulations.
