Abstract: The present invention relates to a process for producing a paper or a board product having increased dimension stability including providing a fibre slurry including never-dried fibres, treating the fibre slurry with a strength composition, and forming a paper or a board product from the treated fibre slurry, where the strength composition includes a permanent wet strength resin component and a sizing agent. The present invention further relates to a use of a strength composition for increasing dimensional stability of a paper and a board, and to a paper or a board product having improved dimensional stability.

Abstract: The invention relates to a use of a strength composition for increasing wet dimensional stability of a moulded pulp article. The moulded pulp article is produced by a method which comprises obtaining a fibre slurry and feeding it to a forming tank of a moulding apparatus, forming a moulded pulp article from the fibre slurry, and drying the moulded pulp article. The strength composition comprises at least one permanent wet strength resin and the strength composition is added to the fibre slurry before the forming of the moulded pulp article.

Abstract: A polyester soil-release polymer (a) and a cosurfactant (b) are used in a laundry composition to improve primary detergency, secondary detergency, and/or soil anti-redeposition and/or to allow a reduction of the amount of surfactant(s) and/or builder(s). Also disclosed is a performance additive comprising at least 20% by weight as actives, of a mixture of (a), (b) and optionally water or other products, in an amount by weight if present of lower than 80%, and the performance additive is mixed with other ingredients to make a laundry composition.
