The present invention relates a process and a system for the point-of-use dilution of microfibrillated cellulose (MFC) from a higher solids content to a lower solids content, for example from a solids content in the range of 5% weight by weight (w/w)-50% w/w, preferably 5% w/w-30% w/w, further preferably 5% w/w-15% w/w, down to a solids content of below 7% w/w, preferably below 5% w/w, preferably to a solids content of 0.01% w/w-5% w/w, further preferably to a solids content of 0.1% w/w-3% w/w. The process at least comprises the following steps: (i) providing microfibrillated cellulose in a solvent, wherein the solids content is in the range of 5% weight by weight (w/w)-50% w/w, preferably 5% w/w-30% w/w, further preferably 5 w/w-15% w/w; (ii) subjecting said microfibrillated cellulose from step (i) to a dilution step in a rotor-stator mixer; (iii) simultaneously to step (ii): injecting solvent into the rotor-stator mixer, or into a volume segment upstream of the rotor-stator mixer, in order to lower the solids content of the microfibrillated cellulose in the rotor-stator mixer.

A soft through-air dried tissue having a soothing feel and method of making the same is disclosed which contains an aqueous softening composition comprising from about 10 to about 20 weight percent of a cationic softening compound, such as quaternary ammonium compounds and imidazolinium compounds; from about 10 to about 20 weight percent of a polyhydroxy compound having a molecular weight of at least about 1,000 g/mol, and optionally a silicone or glycerin. Examples of the cationic softening compound include tallow- and ester-substituted quaternary ammonium compounds having chloride or methyl sulfate as the anion, and examples of the polyhydroxy compound include polyethylene glycols (PEG) or polypropylene glycols (PPG) having a molecular weight of at least about 1,000 g/mol, such as PEG-1000 and PEG-8000.

A pulp mixture includes a lignocellulosic material, water, lignin, an inorganic salt, and a copolymer including two or more structural units chosen from ethylene oxide units, propylene oxide units, (meth)acrylic acid units, ethyl acrylate units, and combinations thereof. The copolymer is free of silicone-containing structural units and the lignin is present in an amount of greater than about 150 ppm, based on a total weight of the pulp mixture.
