  • Publication number: 20100160487
    Abstract: Treated articles with improved water sheeting and soap scum repellency result from forming hydroscopic films on the surfaces of hydrophobic polymeric substrates treated with compositions, kits and methods that employ water-soluble or water-dispersible copolymers having: (i) a first monomer that is capable of forming a cationic charge on protonation; (ii) a second monomer that is acidic and that is capable of forming an anionic charge in the compositions; (iii) optionally, a third monomer having an uncharged hydrophilic group; and (iv) optionally, a fourth monomer that is hydrophobic. Treated articles exhibit a Water Sheeting Index of greater than 6. Treated articles may further exhibit improved soap scum repellency behavior compared to untreated articles.

  • Patent number: 7700540
    Abstract: Cleaning compositions which enhance hard surfaces to exhibit excellent water-spreading and oil-repellency and therefore provide a “next time easier cleaning” consumer benefit contain selected copolymers capable of forming invisible, extremely thin hydrophilic films on treated surfaces. The cleaning compositions feature a water-soluble or water-dispersible copolymer having a first monomer capable of forming a cationic charge on protonation and a second monomer that is acidic and that is capable of forming an anionic charge in the compositions, and may contain an optional third monomer having an uncharged hydrophilic group and/or an optional fourth monomer that is hydrophobic. The cleaning compositions may further contain functional ingredients including surfactants, organic solvents and/or other optional adjuvants to enhance the cleaning performance and aid in preparation of the surface for effective delivery of the copolymer during a cleaning operation.

  • Patent number: 7470290
    Abstract: Hydroscopic polymer gels can be formed by applying a polymer to a surface and allowing water to be sequestered from the atmosphere into the polymer. The polymer gels are formed using methods and compositions employing water soluble or water dispersible copolymers having: (i) a first monomer that is acidic and is capable of forming an anionic charge in the composition; (ii) a second monomer that is amphipathic; (iii) optionally, a third monomer that is hydrophobic; and (iv) optionally, a fourth monomer that that has a permanent cationic charge or that is capable of forming a cationic charge on protonation. The polymer gels are particularly substantive and effective at modifying surfaces such as glass and hydrophobic polymeric substrates to provide soap scum and soil resistance, and easier next time cleaning benefits.

  • Publication number: 20080128003
    Abstract: Incorporating dirt-attracting polycationic polymers, such as polyethyleneimines, into cleaning wipes, mop pads, and similar substrates, improves dirt pick-up and retards redeposition of the dirt back onto the cleaned surface. The polymers can be incorporated directly into the non-woven substrates or they can be formulated with a cleaning composition for use with the substrate. The substrate containing the dirt-attracting polycationic polymers can be employed to clean hard and soft surfaces. The presence of the dirt-attracting polycationic polymers also facilitates biocide release from the substrates.

  • Publication number: 20070256252
    Abstract: A fabric treatment composition that includes at least one zeta potential modifier and a hydrophobic agent with a melting point or glass transition temperature below 100° C. that imparts fabric protection benefits, including improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better handfeel to treated fabrics. Particularly preferred compositions include at least one zeta potential modifier in an amount sufficient to adjust the zeta potential of the composition to be positive and greater than zero millivolts. Particularly preferred compositions also include a fluoropolymer. The composition can be used as a pretreatment prior to washing, through soaking or direct spray application, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, or used prior to or during the drying cycle of an automatic drying machine or refresher machine, or used prior to or in conjunction with an ironing device.
