Abstract
The present application relates to a process for treating a lignocellulosic material with at least one polyorganosiloxane compound, the polyorganosiloxane compound comprising a polyorganosiloxane backbone and at least one ammonium group residue of formula (I): wherein R2, R3, R4 independently from each other signify linear, cyclic or branched, saturated or unsaturated, substituted or unsubstituted C1 to C45 hydrocarbon residues optionally including one or more hetero atoms of O, S, N, signifies the binding site linking to the polyorganosiloxane backbone.
