  • Publication number: 20020061826
    Abstract: A new solvent formulation is invented for removing cured adhesive and coating. It solves the problem that crosslink polymers only can be swelled, and a mechanical force has to be applied to remove the adhesive. The new solvent can dissolve the UV cured crosslink polymers very fast and clean the substrate meanwhile.

  • Patent number: 6391837
    Abstract: An improved composition and method for cleaning shower stall floors and bathtub floors. Applicant's composition is formed by combining a first solvent having a dielectric constant of at least about 15.0, a second solvent having a dielectric constant of less than about 3.0, a third solvent comprising one or more carboxylic ester compounds, a first surfactant, and a second surfactant. Applicant's method comprises depolymerizing to form lower molecular weight compounds oligomeric/polymeric residues formed over a period of time from soap oils, bath oils, and body oils. This depolymerization is effected primarily by the polar first solvent. The lower molecular weight compounds formed by the depolymerization of the oligomeric/polymeric residues are then dissolved in the second solvent/third solvent components. That resulting mixture is then emulsified in water using the first surfactant and/or second surfactant. This water emulsion is then rinsed away.

  • Publication number: 20020055450
    Abstract: An isotropic liquid detergent composition comprising at least one surfactant and from about 0.1 to about 75 weight percent, based on the total weight of the liquid detergent composition, of a water-soluble or water-dispersible polymer having pendant acid functionality and a terminal fragment of a chain transfer agent, wherein the polymer is the polymerization product of a ethylenically unsaturated acid monomer and a C1 to C24 chain transfer agent. Unexpectedly, these polymers are compatible in isotropic liquid detergent formulations. When these polymers are used in a laundering process, they remove soil from textiles, inhibit soil redeposition onto textiles, and function as cobuilders by complexing metal ions present in hard water such as calcium and magnesium which otherwise may complex with the surfactants of a liquid detergent rendering the surfactants water-insoluble.

  • Patent number: 6319885
    Abstract: A composition for removing resists and etching residue from substrates containing at least one nucleophilic amine compound having oxidation and reduction potentials, at least one organic solvent, water and, optionally, a chelating agent is described. The chelating agent is preferred to be included since it provides added stability and activity to the cleaning composition so that the composition has long term effectiveness. If a chelating agent is not present, the composition, while providing for adequate stripping and cleaning upon initial use of the composition following mixing, has only short term stability. In this latter instance, the nucleophilic amine compound and organic solvent components of the composition preferably are maintained separate from each other until it is desired to use the composition. Thereafter, the components are combined. Following use of the composition, the non-used portion of the composition can be disposed of or be reactivated by the addition of a chelating agent.

  • Patent number: 6159915
    Abstract: A composition useful as a paint remover. The composition may include a carbonate, a dibasic ester and a mono-ester. The composition may also contain an organic sulfur-containing compound such as dimethyl sulfoxide (DMSO), a glycol ether, a ketone, or combination thereof. The composition may be used in a process for removing paint by applying it to a painted surface. The compositions have several important attributes, including low toxicity and high efficacy in removing paint and coatings.

  • Patent number: 6150320
    Abstract: Concentrated cleaning compositions are described which exhibit an increase in viscosity simply upon dilution with water. The concentrated and diluted ("ready-to-use") versions are useful in removing food and petroleum grease from hard surfaces (particularly non-horizontal surfaces), and may be formulated as petroleum degreasers, hand soaps and bathroom cleaners. The inventive compositions include an aggregate-forming organic compound, for example an amine oxide, and a nonaggregating or mildly aggregating organic compound, such as an organic alkyl alcohol having from about 4 to about 20 carbon atoms.

  • Patent number: 6136775
    Abstract: An absorbent wipe is provided impregnated with a non-toxic, oil-based cleaning solvent comprising the polar oil d-limonene, a non-polar mineral oil, and a hydrophilic surfactant. The resulting article provides an effective wipe for removing oil-based soils such as oil, grease, tar, ink, and similar contaminants. The article provides a non-toxic wipe which is safe for use on skin, has low volatility, and provides a solvent which self-emulsifies in water. Accordingly, the solvent residue may be easily rinsed and removed from cleaned surfaces. Further, the solvent carrying the removed contaminant may be separated from the wiper to facilitate hazardous waste separation.
