Abstract

Official abstract text for this publication.

Wiping products, such as facial tissues, contain a temperature change 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. In one embodiment, the phase change agent comprises a straight chain hydrocarbon. Hydrocarbons useful as phase change agents include an octadecane, a nonadecane, a heptonoate, or mixtures thereof.

First claim

Opening claim text (preview).

What is claimed: 1. A dry tissue product comprising: a first tissue web comprised of fibers, the tissue web including a first side and a second and opposite side, the tissue web having a bulk of at least about 2 cc/g; a temperature change composition comprising a phase change agent that undergoes a phase change at a temperature of from about 20° C. to about 35° C., the phase change agent having a heat of fusion of at least about 35 cal/g and being present in the tissue web such that the tissue web has a heat absorption factor of at least about 120 cal/m 2 ; and wherein the temperature change composition is contained in an interior of the tissue product so as to not reside on an exterior surface of the tissue product in order to inhibit transfer of the temperature change composition to the skin of the user, wherein the phase change agent comprises octadecane, stearyl heptanoate, nonadecane, stearyl dimethicone and mixtures thereof. 2. A dry tissue product as defined in claim 1 , wherein the tissue product includes a second tissue web and wherein the temperature change composition is located in between the first tissue web and the second tissue web. 3. A dry tissue product as defined in claim 1 , wherein the phase change agent is oil soluble and hydrophobic. 4. A dry tissue product as defined in claim 1 , wherein the phase change agent comprises, octadecane, stearyl heptanoate, stearyl dimethicone and mixtures thereof. 5. A dry tissue product as defined in claim 1 , wherein the phase change agent comprises octadecane. 6. A dry tissue product as defined in claim 1 , wherein the phase change agent comprises stearyl heptonoate or nonadecane. 7. A dry tissue product as defined in claim 1 , wherein the phase change agent has a heat of fusion of at least about 35 cal/g. 8. A dry tissue product as defined in claim 1 , wherein the phase change agent has a heat of fusion of at least about 45 cal/g. 9. A dry tissue product as defined in claim 1 , wherein the temperature change composition includes a carrier, the phase change agent being insoluble in the carrier. 10. A dry tissue product as defined in claim 9 , wherein the carrier is hydrophilic. 11. A dry tissue product as defined in claim 9 , wherein the carrier comprises a glycerin. 12. A dry tissue product as defined in claim 1 , further comprising a lotion composition, the lotion composition being located on an exterior surface of the tissue product. 13. A dry tissue product as defined in claim 1 , wherein the temperature change composition is present on the tissue web in an amount of from about 5 gsm to about 25 gsm. 14. A dry tissue product as defined in claim 2 , wherein the tissue product includes three tissue webs. 15. A dry tissue product as defined in claim 1 , wherein the temperature change composition contains a plurality of phase change agents. 16. A dry tissue product as defined in claim 2 , wherein the tissue product comprises a facial tissue. 17. A dry tissue product as defined in claim 1 , wherein the tissue product comprises a bath tissue containing spirally wound tissue sheets, the temperature change composition being present on an interior surface of the tissue sheets. 18. A dry tissue product as defined in claim 17 , wherein the temperature change composition further comprises a moisturizer. 19. A dry tissue product as defined in claim 17 , wherein the moisturizer comprises a dimethicone. 20. A method for soothing the skin comprising: contacting an exterior surface of a tissue sheet with the skin of a user at a particular location, the tissue sheet containing a temperature change composition comprising a phase change agent that undergoes a phase change at a temperature of from about 23° C. to about 32° C., the phase change agent having a heat of fusion of at least about 35 cal/g and being present in the tissue sheet in an amount such that the tissue web has a heat absorption factor of at least about 120 cal/m 2 , the phase change agent comprising octadecane, stearyl heptanoate, nonadecane, stearyl dimethicone and mixtures thereof, wherein the temperature change composition is contained in an interior of the tissue sheet so as to not reside on the exterior surface in order to inhibit transfer of the temperature change composition to the skin of the user; and holding the tissue sheet in contact with the skin an amount of time sufficient for heat transfer to take place from the user to the tissue sheet so as to cause the phase change agent to undergo a phase change thereby causing a cooling sensation on the skin. 21. A method as defined in claim 20 , wherein the tissue sheet comprises a plurality of tissue webs, the temperature change composition being located in between two opposing webs. 22. A method as defined in claim 20 , wherein the phase change agent comprises octadecane, stearyl heptanoate, stearyl dimethicone or mixtures thereof. 23. A method as defined in claim 20 , wherein the tissue sheet is contacted with a nose of the user. 24. A method as defined in claim 20 , wherein the temperature change composition is contained in the tissue sheet in an amount from about 5 gsm to about 25 gsm. 25. A dry bath tissue product comprising: a plurality of tissue sheets separated by perforation lines, the tissue sheets being spirally wound to form a roll, the tissue sheets including a first exterior surface and a second exterior surface; and a temperature change composition contained in an interior of the tissue product so as to not reside on the exterior surfaces of the tissue product in order to inhibit transfer of the temperature change composition to the skin of the user, the temperature change composition comprising a phase change agent that undergoes a phase change at a temperature of from about 20° C. to about 35° C., the phase change agent having a heat of fusion of at least about 35 cal/g and being present on the tissue sheets such that the tissue sheets have a heat absorption factor of at least about 120 cal/m 2 , the phase change agent comprising octadecane, stearyl heptanoate, nonadecane, stearyl dimethicone and mixtures thereof. 26. A dry bath tissue product as defined in claim 25 , wherein the temperature change composition further comprises a moisturizer. 27. A dry bath tissue product as defined in claim 26 , wherein the phase change agent comprises octadecane, stearyl heptanoate, or mixtures thereof combined with stearyl dimethicone. 28. A method for creating the perception of moisture in a dry bath tissue product comprising contacting an exterior surface of a dry bath tissue with a perineal skin, the dry tissue containing a temperature change composition contained in an interior of the tissue product so as to not reside on an exterior surface of the tissue product in order to inhibit transfer of the temperature change composition to the skin of the user, the tissue product comprising a phase change agent that undergoes a phase change at a temperature of from about 23° C. to about 32° C., the phase change agent having a heat of fusion of at least about 35 cal/g and being present in the dry bath tissue in an amount such that the bath tissue has a heat absorption factor of at least about 120 cal/m 2 , the phase change agent comprising octadecane, stearyl heptanoate, nonadecane, stearyl dimethicone and mixtures thereof.
