Abstract

The invention relates to a papermaking process in which the static potential of the fibres/paper product can be controlled and reduced while enhancing the softness of the 5 produced paper product. The papermaking process comprises adding to a suspension of cellulosic fibres: (i) a smectite clay (ii) at least one anionic compound selected from anionic microparticles and anionic surfactants 10 (iii) at least one polymer which is cationic, non-ionic or amphoteric (iv) at least one non-ionic surfactant; and/or an oil, wax or fat.
