  • Patent number: 6818608
    Abstract: A cured resin dissolving composition comprising an alkyl ammonium fluoride dissolved in a wide variety of solvents and co-solvents with a soluble amine and surfactant. The composition is ionized to release fluoride which penetrates and reacts with the cured resin causing bond cleavage, breakdown, and dissolution of polymeric structure. The solvent system may be composed of hydrophilic solvents such as amides, ketones, alcohols, esters, and ethers, as well as hydrophobic families such as alkanes, alkenes, halogenated hydrocarbons, and aromatic hydrocarbons of varying carbon chain length and molecular weight. The rate of reactivity of polymer breakdown is concentration dependent upon ionized fluoride, stimulated by solution polarity and upon the amine triggered release from the organo-fluoirde. This rate is determined to be optimum in hydrophilic solvent systems with an amine. The product may be used in manufacturing to remove unwanted cured resins and their residues.

  • Patent number: 6323014
    Abstract: There is provided a process for enhancing the activity of a phenol oxidizing enzyme, comprising adding to the enzyme, as an enhancer for the activity of the enzyme, one or more compounds having the formula: wherein: A is an optionally substituted electron-withdrawing group, chosen from the group consisting of nitrile, carboxyl, and esters and salts thereof, amides, aldehydes, ketones, sulfoxides, sulfones, or sulphonates, and B is an optionally substituted electron-donating group, chosen from the group consisting of the oxide anion, sulfide anion, oxides, amines, imines, hydroxides, sulfides, ethers, carboxylic acids, and halogen substituents, and R1-R5 may each independently represent hydrogen, hydroxy, halogen, nitroso, formyl, carboxyl, and esters and salts thereof, carbamoyl, sulfo, and esters and salts hereof, sulfamoyl, nitro, amino, phenyl, C1-C20 alkyl, C1-C8 alkoxy, carbonyl-C1-C6-alkoxy, aryl-C1-C6-alkyl, and R2 and R5 together may form an alkylene group or an alkenylene group.

  • Publication number: 20010036908
    Abstract: A laundry treatment composition comprising peroxygen bleach and a water-soluble or water dispersible rebuild agent for redeposition onto a fabric during the laundry process, wherein the fabric rebuild agent undergoes during the laundry process, a chemical change by which change the affinity of the material for the fabric is increased. The peroxygen bleach was found to increase the deposition of the fabric rebuild agent.

  • Patent number: 6277153
    Abstract: A chemical cleaning system for a multi-tank or a single-tank laundry washing machine, having at least two separate components for aqueousdissolution or dilution to respective use concentrations, a first component comprising a proteolytic enzyme, and a second component comprising an imidoperoxycarboxylic acid, particularly phthaloylaminoperoxycaprbic acid (PAP), wherein the first component is introduced into a prewash zone or step, and the second component is introduced into a main wash zone or step. When using this system, it was found that effective cleaning could be obtained even at relatively low main wash temperatures of 45-55° C. As a result, much less energy was needed and a considerable reduction of textile damage was observed as compared with cleaning systems of the prior art.
