Therefore, the roles generally need components that supply the deficiencies resulting from the raw material used, better represented by the cationic starches based on maize and / or cassava based starch and / or modified starches, which are often not enough to reach the minimum required level. Hence the need to use imported chemical agents identified as Cationic Polymers in aqueous solution or modified Polyamides and / or Polyamines.
