A manufacturing method of a paper, board or the like having a grammage in a range of 125-600 g/m.sup.2, preferably 150-210 g/m.sup.2, including adding a paper sizing agent including maleated vegetable oil and an alkenyl succinic anhydride (ASA) to a fibre stock including at least 80 weight-% of recycled fibre material and having calcium concentration of at least 500 mg/l, expressed as CaO.

An emulsion is provided for defoaming water used in processing of various products such as cellulose or wood-based products or in food processing which is formed by reacting a fatty acid with a compound selected from the group consisting of ammonia, sodium, potassium and combinations thereof so as to form a water soluble soap, dispersing the water soluble soap in water and homogenizing the dispersed water soluble soap with hydrophobic oil or hydrocarbon oil to produce the emulsion. Methods for preparing the emulsion and using the emulsion are also provided. The emulsion is advantageous in that it can improve water resistance and/or reduce the use of water resistant additives during processing of cellulose or wood-based products or food-grade products.

The invention relates to plant-derived cellulose-containing particles useful as strengthening agents in water based systems and to a process for preparing cellulose-containing particles from plant material, which process involves treating said plant material with a peroxide reagent. The process can be controlled to produce cellulose-containing particle having a viscosity up to about 2500 cps.
