Description

Calcium dodecylbenzenesulfonate (CAS 26264-06-2 ) is an anionic calcium surfactant used across industrial formulation. It delivers emulsification, wetting, and dispersion performance in various applications. This chemical is particularly effective where sodium-based sulfonates are unsuitable due to electrolyte sensitivity or oil-phase compatibility requirements. It is sold under trade names such as Sinnozon NCX 70 and Soprofor S 70. In agrochemical formulations, it functions as an emulsifier and wetting agent in emulsifiable concentrate pesticides. This improves active ingredient dispersion in water for better agricultural performance. Coatings and adhesive manufacturers use it to stabilize pigment dispersions and improve substrate wetting on low-energy surfaces. It ensures a more uniform application and better adhesion for industrial coatings. In metalworking and lubricant formulations, it acts as an emulsifier in soluble cutting oils and corrosion-inhibiting fluids. This helps maintain the stability of the oil-in-water emulsions during heavy machining. Textile and leather processors apply it as a wetting and penetration agent in dyebath and finishing operations. It assists in the even distribution of dyes and treatments throughout the material fibers. The product is typically supplied as a viscous liquid or paste with active content commonly ranging around 70 percent. This concentration is reflected in the designation of several common trade-name products. Technical grade is the standard commercial offering with specifications aligned to agrochemical and industrial surfactant requirements. Drum and IBC packaging are the norm for bulk industrial supply chains. Contact us for supply of Calcium dodecylbenzenesulfonate Request Quote
