Patent number: 6391837Abstract: 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.Type: GrantFiled: September 8, 2000Date of Patent: May 21, 2002Inventor: Kenneth C. Coleman
