Abstract

The precipitation of an anionic surfactant due to hard water can cause problems in foam forming process. Addition of a nonionic or a zwitterionic surfactant as a cosurfactant with the anionic surfactant inhibits the precipitation of the anionic surfactant. 20-25 mol-% addition of the co-surfactant is recommended to prevent the precipitation of the anionic surfactant. Addition of Tween 20 with sodium dodecyl sulphate (SDS) was found to decrease the SDS residue in foam-formed paper sheets. The paper sheets produced with the surfactant mixture also exhibited higher tensile index compared to sheets made with only SDS or Tween 20.
