  • Patent number: 6787512
    Abstract: Generally speaking, the present invention is a water-soluble copolymer film comprising a hydrolyzed copolymer of vinyl acetate and a second monomer, the resultant polyvinyl alcohol copolymer having a degree of hydrolysis, expressed as a percentage of vinyl acetate units converted to vinyl alcohol units, of from about 90% to 100%. The second monomer is preferably selected from the group of monomers having carboxylate functionality or sulfonate functionality. The resulting water-soluble copolymer film is disclosed for use in making pouches to contain a unit dose of liquid detergent, such as a liquid laundry detergent. However, it is an aspect of the copolymer film that film solubility is not significantly affected adversely by the detergent. Such film produces pouches having a greater storage shelf-life over prior art water-soluble film.

  • Patent number: 6329335
    Abstract: A process for the production of detergent tablets containing surfactants, builders and optionally other detergent ingredients. To produce the tablets, particulate detergent compositions containing 5 to 20% by weight of an overdried amorphous silicate, 0.5 to 10% by weight of polyethylene glycol and 1 to 15% by weight of water or aqueous solutions, based on the weight of the tablet formed, are tabletted under pressure. Despite low tabletting pressures, the process according to the invention gives tablets combining high fracture resistance and stability in storage with excellent dissolving behavior.
