  • Publication number: 20120157369
    Abstract: The present invention comprises polymers having optionally substituted aromatic residues in the polymer backbone and/or side chains, useful for the removal and/or dispersion of hydrophilic soils from textiles. The present invention also comprises a method for the removal of hydrophilic soils from textiles comprising the step of contacting the soil with a polymer that comprises optionally substituted aromatic residues in the backbone and/or side chains. The present inventive polymers and method are particularly useful in the context of washing or pretreatment agents that effectively remove red wine, fruit, vegetable, food product, or beverage stains from textiles.

  • Publication number: 20120077726
    Abstract: The aim of the invention is to reduce the damage to cellulosic material during the bleaching treatment of cellulosic material by using catalysts with bleaching activity, without significantly impacting the bleaching performance in the process. This was achieved largely by way of a method for bleaching cellulosic material in the presence of a peroxygen-containing bleaching agent and a bleach-boosting transition metal complex, which is carried out in the presence of spherical polyelectrolyte brushes. The spherical polyelectrolyte brushes preferably contain the transition metal complex in a colloidally bound manner.
