Patent number: 8123905Abstract: 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.Type: GrantFiled: March 23, 2010Date of Patent: February 28, 2012Assignee: Georgia-Pacific Consumer Products LPInventors: Phuong V. Luu, Steven L. Edwards, David W. White, Brigitte K. Schauer, Martin A. Hynnek

Patent number: 8012495Abstract: 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.Type: GrantFiled: December 8, 2005Date of Patent: September 6, 2011Assignee: Georgia-Pacific Consumer Products LPInventors: Phuong V.

Patent number: 6352700Abstract: A substrate treated with a lotion including a skin pH balancing compound and a base lotion. The pH balancing compound is preferably an organic acid, such as an alpha-hydroxy acid, an alpha-dihydroxy acid, or a beta-hydroxyacid, a combination of an organic acid and a salt of an organic acid, or a buffer combination, such as combinations of citric acid and disodium phosphate, or disodium citrate and sodium hydroxide. The preferred lotion has the effect of maintaining the skin acid mantle while making the treated substrate, preferably tissue, towel or napkin, optionally wet-strengthened, wipe or nonwoven material, feel smooth, lubricious and nongreasy. The skin care benefits of the lotionized substrate are expressed whether the product is used dry or prewetted with water.Type: GrantFiled: May 3, 1999Date of Patent: March 5, 2002Assignee: Fort James CorporationInventors: Phuong V.
