Abstract

The present invention relates to a method for producing a cellulose-based product having lipophobic resistance, said method comprising- providing an aqueous mixture comprising cellulose pulp, said mixture having a solid content between 0.1- 2%;- adding a saccharide fatty acid ester (SFAE) to the mixture in an amount between 0.5 - 10 wt% based on the total mixture fiber content;- adding a retention aid chemical to said mixture arranged to improve retention of said SFAE to the cellulose fibers, and - producing a cellulose-based product from said mixture, wherein the electrostatic charge balance of the mixture is adjusted to be on the anionic side.
