  • Patent number: 8894814
    Abstract: Wiping products, such as facial tissues, contain an interior temperature change composition and an exterior hydrophilic lotion composition that can provide a cooling sensation when contacted with the skin of a user. The temperature change composition, for instance, can contain one or more phase change agents that undergo a phase change at slightly elevated temperatures. The phase change agents, in one embodiment, can have a relatively high heat of fusion. When undergoing a phase change, the phase change agents absorb heat and thereby provide a cooling feeling to the skin of a user. The hydrophilic lotion composition may contain a carrier and a thermo-reversible gelling agent. The hydrophilic lotion composition maintains the temperature change composition within the tissue and helps to prevent skin irritation.

  • Patent number: 7008507
    Abstract: A method is disclosed for application of compositions onto non-woven webs, such as paper webs. The present invention is also directed to products made from the process. In general, the method includes applying a composition to a non-woven web using a non-impact printer, such as an ink jet printer. The composition is applied, in one embodiment, as droplets that remain as discrete shapes on the substrate. In this manner, treated areas and untreated areas are formed on the web. Through this process, the water absorption and control properties of the web can be adjusted as desired while simultaneously treating the web with a composition that improves the physical and/or chemical properties of the web.

  • Patent number: 6872820
    Abstract: Finely divided polysacharide derivatives are described. The finely divided polysacharide derivatives are prepared by a process comprising: a) forming an aqueous composition comprising a polysaccharide derivative and water, in which the polysaccharide derivative is soaked or dissolved; b) converting the polysaccharide derivative of the aqueous composition into finely divided solid particles by, (i) contacting the aqueous composition with superheated water vapor in a dryer-pulverizer; or (ii) causing the polysaccharide derivative of the aqueous composition to flocculate; and c) optionally drying the finely divided solid particles of step b). The primary structures of the polysaccharide starting material are largely removed, and the product has a shape factor of less than 5 and greater than or equal to 1.

  • Patent number: 6860967
    Abstract: A tissue paper penetrated with a lotion composition being a liquid, viscous W/O emulsion includes (A) 20 to 75 weight % of at least one oil, (B) 3 to 40 weight % of at least one non-ionic W/O emulsifier, (C) optionally 0.5 to 10 weight % of at least one wax, (D) 1 to 15 weight % of at least one humectant, (E) 6 to 25 weight % of water. The lotioned tissue paper of the invention shows an excellent surface softness and in particular bulk softness. Simultaneously it is capable of efficiently transferring lotion to the skin of the user.

  • Publication number: 20040250969
    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.
