Calcium dodecylbenzene sulfonate Application
-
Agrochemical & Pesticide Emulsifier: Functions as the primary lipophilic anionic surfactant (widely known as Emulsifier 500#) blended with nonionic surfactants to formulate Emulsifiable Concentrates (EC), Microemulsions (ME), and Emulsions in Water (EW) for herbicides, insecticides, and fungicides.
-
Oilfield Drilling & Demulsification Chemicals: Utilized in oil-based drilling muds, enhanced oil recovery (EOR) formulations, and crude oil demulsifiers due to its superior interfacial tension reduction and oil-solubility.
-
Industrial Cleaners & Degreasers: Acts as a strong oil-soluble detergent and wetting agent in solvent-based metal cleaners, engine degreasers, and dry-cleaning formulations.
-
Coatings, Paints & Polymer Emulsion Processing: Employed as an emulsifying and dispersing agent in alkyd resin coatings, pigment dispersions, and specialty rubber/plastic polymerization processes.
Standard Packaging: 200 kg/drum; 20kg/bag
