  • Patent number: 5525345
    Abstract: A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 5 to about 15% by weight. The lotion composition comprises plastic or fluid emollient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, an agent such as sorbitan stearates or N-cocoyl, N-methyl glucamide to immobilize the emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided.

  • Patent number: 5213588
    Abstract: Disclosed are abrasive wiping articles, e.g., nonwoven, preferably paper towels, which comprise an absorbant nonwoven substrate having printed thereon a cured scrubbing bead mixture which comprises a) certain carboxylated, ionically-charged polymeric abrasive particles, b) a carboxyl group-containing polymeric adhesive material, and c) an amino-epichlorohydrin, e.g., Kymene.RTM., cross-linking agent. The polymeric abrasive particles range in size from about 20 to 400 microns and have a Knoop hardness of from about 4 to 25. The polymeric adhesive material, upon curing, has a Knoop hardness of from about 0.5 to 17.Preferred wiping articles of the foregoing type have a pattern of the scrubbing bead mixture printed onto from about 20% to 70% of the surface area of a paper substrate with the abrasive particles affixed to the substrate in such a manner that their exposed portion extends for a distance of from about 40 to 300 microns above the surface of the paper substrate.

  • Patent number: 4818598
    Abstract: The present invention relates to absorbent structures in which hydrogel has improved ability to absorb salt-containing fluids due to inclusion within the absorbent structures of fibrous anion exchange materials. The absorbent structures of the present invention comprise hydrogel and fibrous anion exchange material (e.g., DEAE cellulose), and, optionally, fibrous cation exchange materials and/or conventional absorbent materials; said absorbent structures having an equilibrium pH of from about 5 to about 11. The present invention further relates to disposable absorbent products (e.g., diapers, incontinent pads, sanitary napkins) which comprise absorbent structures of the present invention.
