Abstract

Official abstract text for this publication.

The invention provides methods and compositions for softening paper. An inventive composition and method of its use softens paper products (like tissue paper) by de-bonding its cellulose fibers and by improving the smoothness of the resulting paper. The invention forms a surfactant-polymer complex that attaches de-bonding non-ionic surfactants to cellulose fibers that would otherwise not be retained by the cellulose fibers. This complex prevents the fibers from bonding with each other and makes the paper product smoother. Best of all, the composition is environmentally superior and is a non-toxic.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of softening a paper product, the method comprising: adding a composition to a mass containing cellulose fibers, the composition comprising a combination of at least one non-ionic surfactant and at least one cationic polyelectrolyte polymer coagulant, the cationic polyelectrolyte polymer coagulant selected from ethylene dichloride/ammonia polymers, ethyleneimine polymers, acrylamidopropyltrimethyl ammonium chloride polymers, polyamidoamines,…
