Disposable absorbent articles with controlled skin hydration effect

Abstract

A disposable absorbent article covering certain parts of the body of the wearer and comprising a loading area, a storage area as well as chassis area, whereby the absorbent article has a specific Skin Hydration Value, calculated from the individual Skin Hydration values of the respective areas.

What is clamed is:  
     
         1 . An absorbent article capable of covering certain parts of the body and comprising distinct areas including a loading area, a storage area having multiple zones and a chassis area, wherein said article has a Skin Hydration Value of less than about 1300, calculated based on a summation of individual Skin Hydration Value of said loading area, said storage area, and said chassis area, wherein said Skin Hydration Value of each area is determined by a fluid transfer method using hydratable collagen film materials and can be expressed in terms of (mg of moisture pick up/area of hydratable collagen film material)×(total area of individual loading area, storage area or chassis area).  
     
     
         2 . An absorbent article according to  claim 1 , wherein said storage area comprises varying caliper zones.  
     
     
         3 . An absorbent article according to  claim 1 , wherein said storage area comprises a first zone having a first average density and a second zone having a second average density, said first average density being lower than said second average density.  
     
     
         4 . An absorbent article according to  claim 1 , wherein said storage area comprises a first zone having a first average basis weight and a second zone having a second average basis weight, said first average basis weight being lower than said second average basis weight.  
     
     
         5 . An absorbent article according to  claim 1 , wherein said loading area has multiple zones.  
     
     
         6 . An absorbent article according to  claim 1 , wherein said chassis area has multiple zones.  
     
     
         7 . An absorbent article according to  claim 1 , wherein said Skin Hydration Value of said absorbent article is less than about 600.  
     
     
         8 . An absorbent article according to  claim 1 , wherein said Skin Hydration Value of said absorbent article is less than about 300.  
     
     
         9 . An absorbent article according to  claim 1 , wherein said loading area has a Skin Hydration Value of less than about 150, calculated based on (mg of moisture pick up/area of hydratable collagen film material)×(total area of the loading area).  
     
     
         10 . An absorbent article according to  claim 1 , wherein said storage area has a Skin Hydration Value of less than about 20, calculated based on (mg of moisture pick up/area of hydratable collagen film material)×(total area of the storage area).  
     
     
         11 . An absorbent article according to  claim 1 , wherein said chassis area has a Skin Hydration Value of less than about 1250, calculated based on (mg of moisture pick up/area of hydratable collagen film material)×(total area of the chassis area).  
     
     
         12 . An absorbent article according to  claim 11  wherein said chassis area has a Skin Hydration value of less than about 500.  
     
     
         13 . An absorbent article capable of covering certain parts of the body and comprising distinct areas including a loading area, a storage area and a chassis area, wherein each area comprises a large number of zones which form a substantially continuous mapping of each area, and wherein said article has a Skin Hydration Value of less than about 1300, calculated based on a summation of individual Skin Hydration Value of said loading area, said storage area, and said chassis area, wherein said Skin Hydration Value of each area is determined by a fluid transfer method using hydratable collagen film materials and can be expressed in terms of (mg of moisture pick up/area of hydratable collagen film material)×(total area of individual loading area, storage area or chassis area).  
     
     
         14 . An absorbent article according to  claim 13 , wherein said Skin Hydration Value of said absorbent article is less than about 600.  
     
     
         15 . An absorbent article according to  claim 14 , wherein said Skin Hydration Value of said absorbent article is less than about 300.  
     
     
         16 . An absorbent article according to  claim 13 , wherein said loading area has a Skin Hydration Value of less than about 150, calculated based on (mg of moisture pick up/area of hydratable collagen film material)×(total area of the loading area).  
     
     
         17 . An absorbent article according to  claim 13 , wherein said storage area has a Skin Hydration Value of less than about 20, calculated based on (mg of moisture pick up/area of hydratable collagen film material)×(total area of the storage area).  
     
     
         18 . An absorbent article according to  claim 13 , wherein said chassis area has a Skin Hydration Value of less than about 1250, calculated based on (mg of moisture pick up/area of hydratable collagen film material)×(total area of the chassis area).  
     
     
         19 . An absorbent article according to  claim 18 , wherein said chassis area has a Skin Hydration Value of less than about 500.
