Delivery Product for Topical Compositions

Abstract

A delivery product is used to deliver a skin composition to the skin of a user. The delivery product includes a thermo-responsive polymer film. The polymer film is solid at room temperature but, once contacted with the skin, increases in temperature and degrades. A skin composition is associated with the polymer film. The skin composition can be applied to a surface of the film or can be incorporated into the film. The skin composition is released by the polymer film for treating the skin of the user.

1 . A delivery product for topical skin compositions comprising:
 a thermo-responsive polymer film, the thermo-responsive polymer film being solid at a temperature of 23° C.;   a topical skin composition in association with the thermo-responsive polymer film, the topical skin composition containing a skin care active, a medicament or mixtures thereof; and   wherein the thermo-responsive polymer film changes properties at a temperature greater than 23° C. but less than about 37° C. so as to cause the solid film to degrade such that when the delivery product is placed in contact with a person's skin, the thermo-responsive polymer film increases in temperature and the film degrades.   
     
     
         2 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film changes properties at a temperature of from about 30° C. to about 34° C. 
     
     
         3 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film comprises a chitosan. 
     
     
         4 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film comprises a polyacrylic acid or derivatives thereof. 
     
     
         5 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film comprises a N,N-dialkylacrylamide copolymer. 
     
     
         6 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film comprises an encapsulated paraffin wax. 
     
     
         7 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film is substantially water insoluble. 
     
     
         8 . A delivery product as defined in  claim 1 , wherein the skin care active or the medicament comprises an antibacterial agent, a deodorant, a skin moisturizer, a cleanser, an anti-itch agent, a cooling agent, a diaper rash agent, or mixtures thereof. 
     
     
         9 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film is laminated to a releasable backing layer that is configured to be separated from the thermo-responsive polymer film when the thermo-responsive polymer film is applied to a person's skin. 
     
     
         10 . A delivery product as defined in  claim 1 , wherein, once the thermo-responsive polymer film is placed on a surface at a temperature of 34° C. in an ambient environment, the thermo-responsive polymer film takes at least 30 minutes to completely degrade. 
     
     
         11 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film does not contain a skin adhesive on any surface thereof. 
     
     
         12 . A delivery product as defined in  claim 1 , wherein the thermo-responsive polymer film is comprised of an interpenetrating polymer network. 
     
     
         13 . A system for delivering a topical skin composition comprising:
 an absorbent article configured to be placed adjacent to the skin of a wearer, the absorbent article including an interior surface configured to be placed adjacent to the skin and an opposite exterior surface; and   an insert that is manually positioned on the interior surface of the absorbent article for contact with the wearer's skin, the insert comprising a delivery product defined in  claim 1 .   
     
     
         14 . A system as defined in  claim 13 , wherein the absorbent article comprises a diaper or a pant. 
     
     
         15 . A system as defined in  claim 13 , wherein the absorbent article comprises a feminine hygiene pad. 
     
     
         16 . A system as defined in  claim 13 , wherein the absorbent article comprises an adult incontinence garment. 
     
     
         17 . A system as defined in  claim 13 , wherein the absorbent article comprises a wound dressing. 
     
     
         18 . A system as defined in  claim 14 , wherein the skin care active or medicament contained in the topical skin composition comprises a diaper rash agent. 
     
     
         19 . A system as defined in  claim 13 , wherein the thermo-responsive polymer film comprises a polyacrylic acid or derivative thereof, or a N,N-dialkylacrylamide copolymer. 
     
     
         20 . A system as defined in  claim 13 , wherein the thermo-responsive polymer film comprises an encapsulated paraffin wax. 
     
     
         21 . A system as defined in  claim 13 , wherein the thermo-responsive polymer film is substantially water insoluble. 
     
     
         22 . A system as defined in  claim 13 , wherein the skin care active or the medicament comprises an antibacterial agent, a deodorant, a skin moisturizer, a cleanser, an anti-itch agent, a cooling agent, a diaper rash agent, or mixtures thereof. 
     
     
         23 . A system as defined in  claim 13 , wherein the thermo-responsive polymer film is laminated to a releasable backing layer, the releasable backing layer being removed from the thermo-responsive polymer film when the insert is manually positioned on the interior surface of the absorbent article. 
     
     
         24 . A delivery product as defined in  claim 1 , wherein the topical skin composition is incorporated into the thermo-responsive polymer film.
