  • Publication number: 20080044644
    Abstract: An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.

  • Publication number: 20080008865
    Abstract: A disposable anti-microbial paper towel and dispensing method includes disposing paper towel in an automatic touchless dispenser which is adapted to generate a touchless proximity signal upon nearness of a consumer, and dispensing the paper towel in response to the proximity signal. A typical invention towel has: (i) a cellulosic web characterized in that the web is substantially without crepe bars and has an unlotioned MD bending length of at least 3.5 cm; and (ii) a transferable lotion composition comprising an emollient and anti-microbial agent, the lotion composition being immobilized on the cellulosic web in a semi-solid or solid form. The transferable lotion composition is selected from lotion compositions which are transferable upon contact with water or lotion compositions which are transferable upon application of body heat.

  • Publication number: 20070237807
    Abstract: A disposable paper towel with an anti-microbial lotion and is provided with a chromatic transfer indicator which undergoes a delayed, visually perceptible color change at a predetermined time after the towel is wetted. An anti-microbial lotion on the towel increases water absorbency times (WAR) to further promote lotion transfer to the skin and increase lotion transfer effectiveness.

  • Publication number: 20070087041
    Abstract: A lotion includes a micro-emulsion composition, which is liquid at room temperature and undergoes a phase change to a semi-solid or solid upon contact with a substrate. The micro-emulsion composition can include a polar emollient, a non-polar emollient, a non-ionic surfactant, and a co-surfactant. The invention also includes a substrate treated with the lotion.

  • Publication number: 20060135384
    Abstract: An antimicrobial liquid hand soap composition includes: (a) water; (b) a primary hand soap composition; (c) a biocide; and (d) a glutinous surfactant having a relative contact angle value with water of at least about +10° with respect to the primary hand soap composition. The glutinous surfactant is present in an amount effective to alter the tactile properties of the primary soap composition to promote longer and more thorough hand washing by eliciting a response to the soap's feel on the skin.

  • Publication number: 20060110432
    Abstract: A paper towel includes: (a) a cellulosic towel web; and (b) a lotion emulsion disposed on the towel web. The lotion emulsion is substantially liquid at room temperature and includes a polar emollient and a non-polar emollient as well as a surfactant composition comprising a nonionic surfactant; wherein the emollients and surfactant composition are selected such that the lotion emulsion is immobilized on the towel web in a semi-solid or solid state and the lotion emulsion is capable of forming an aqueous gel upon contact with water. Preferably, the lotion emulsion is a waterless micro-emulsion which is also capable of forming an aqueous micro-emulsion with water.
