Abstract:
A method for producing an emulsion of ASA in an aqueous solution of a cationic amylaceous substance, without having to use a loop for recirculating the product at the emulsification unit. The produced emulsion is characterized by both a fine and monodisperse particle size, and no overheating is involved that could lead to negative phenomena of hydrolyzing the ASA. The corresponding production device is also described.
