Abstract

Abstract A lotion composition for killing such viruses as rhinovirus and influenza in addition to imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 2 to about 20% by weight, and tissue paper treated with such lotion compositions are disclosed. The anti-viral action of the lotion is due to the addition of an organic acid such as citric acid or a mixture of adipic acid, glutaric acid, and succinic acids. The solubilization of the organic acids within the lotion matrix and with the infected mucus is aided by the addition of such hydrophilic solvents as propylene glycol and polyethylene glycols. The lubricious lotions also contain a plastic or fluid emollient such as petrolatum, an immobilizing agent such as a fatty alcohol or fatty acid to immobilize the emollient on the surface of the tissue paper web and optionally a non-ionic 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. The anhydrous nature of the lotions also aids in the maintenance of such physical properties as tensile and caliper.

Claim 2
Dependent Claim 341 words
A lotioned tissue paper having applied to at least one surface thereof, in an amount of from about 2 to about 30% by weight of the dried tissue paper, an anti-viral lotion composition which is semisolid or solid at 20° C. and which comprises: (A) from about 1 to about 25% of an organic acid capable of killing such viruses as rhinovirus and influenza which come into contact with the anti-viral lotion, wherein said anti-viral organic acid is a solid at room temperature and comprises a member selected from the group consisting of citric acid, adipic acid, glutaric acid, succinic acid, and mixtures thereof; (B) from about 5 to about 25% of a hydrophilic solvent capable of aiding in the dissolution of the organic acid, said solvent may either be liquid or solid at room temperature and comprises a member selected from the group consisting of glycerin, propylene glycol, hexylene glycol, and polyethylene glycols ranging in molecular weight from about 200 to about 900, and mixtures thereof; (C) from about 5 to about 60% of a substantially water free skin emollient having a plastic or fluid consistency at 20° C. and comprises a member selected from the group consisting of petroleum-based emollients, fatty acid ester emollients, fatty alcohol emollients, and mixtures thereof; (D) from about 5 to about 50% of an agent capable of immobilizing said emollient on the surface of the tissue paper, said immobilizing agent having a melting point of at least about 35° C. and comprising a member selected from the group consisting of C 12 -C 22 fatty alcohols, C 12 -C 22 fatty acids, sorbitan stearates, waxes, and mixtures thereof; (E) from 1% to about 50% of a non-ionic surfactant with said surfactant having an HLB value of at least about 4; and (F) optionally contains from about 0.1% to about 20% of a natural oil, vitamin, or other additive comprising a member selected from the group consisting of aloe, vitamin E, panthenol, camphor, thymol, menthol, eucalyptol, geraniol, lemon oil, methyl salicylate, clove and mixtures thereof.
