  • Patent number: 7531049
    Abstract: A composition for removing urethane products from a wide variety of substrates without the need for scraping, scrubbing, sanding, sandblasting and the like is provided. The composition is formed by combining water, a polar organic solvent, a mixture of organic esters, a hydrocarbon, and a polyether. The composition may optionally be formed by combining the components recited above along with an anionic surfactant. The composition may optionally be formed by combining the components recited above along with a thickener.
    Type: Grant

  • 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.
