Adhesive composition adapted for attachment to skin

Abstract

An adhesive composition is provided that is adapted for attachment to skin. The adhesive composition includes styrene-ethylene/butylene-styrene, polyolefin, polybutene, wax, polyacrylic acid, and an absorbent material.

What is claimed is: 
     
         1 . An adhesive composition for attachment to skin, the adhesive composition comprising 4-9% (w/w) styrene-ethylene/butylene-styrene, 3-6% (w/w) polyolefin, 35-41% (w/w) polybutene, 2-4% (w/w) wax, 4-20% (w/w) polyacrylic acid, and a total of 20-40% (w/w) of one or more absorbent material(s). 
     
     
         2 . The composition according to  claim 1 , wherein the composition consists of 4-9% (w/w) SEBS, 3-6% (w/w) polyolefin, 35-41% (w/w) polybutene, 2-4% (w/w) wax, 4-20% (w/w) PAA, and a total of 20-40% (w/w) of one or more further absorbent material(s). 
     
     
         3 . The composition according to  claim 1 , wherein the composition has an absorption at 2 hours, measured as described herein, of at least 0.1 g/cm 2 /2 h. 
     
     
         4 . The composition according to  claim 1 , wherein the composition has an absorption at 24 hours, measured as described herein, of at least 0.5 g/cm 2 /24 h. 
     
     
         5 . The composition according to  claim 1 , wherein the composition has a gel strength, measured as described herein, below 4 N. 
     
     
         6 . A device for attachment to a skin surface of a user, the device comprising an adhesive composition according to  claim 1  and at least one release liner. 
     
     
         7 . The device according to  claim 6 , wherein the device has a skin-facing surface and a surface facing away from the skin during use, and wherein the release liner is disposed on the skin-facing surface. 
     
     
         8 . The device according to  claim 6 , wherein a second release liner is disposed on the surface facing away from the skin during use. 
     
     
         9 . The device according to  claim 6 , wherein the device is ring or oval shaped with a through-going hole for fitting around a stoma of the user. 
     
     
         10 . The device according to  claim 6 , wherein the outer diameter of the device is in the range 30-60 mm. 
     
     
         11 . The device according to  claim 6 , wherein the diameter of the hole is in the range 10-25 mm. 
     
     
         12 . The device according to  claim 6 , wherein the thickness of the device, including release liner(s) is in the range 3.5-5.5 mm. 
     
     
         13 . A method of using of the adhesive device according to  claim 6 , comprising the steps of
 providing a device according to  claim 6 ,   removing the at least one release liner from the device, and   attaching the device to a skin surface surrounding a stoma.   
     
     
         14 . The method according to  claim 13 , comprising a further step of attaching the device to an adhesive baseplate of an ostomy device. 
     
     
         15 . The method according to  claim 13 , wherein the device has a skin-facing surface and a second surface facing away from the skin during use, with the release liner is disposed on the skin-facing surface, the method further comprising removing the release liner from the skin-facing surface of the device. 
     
     
         16 . The method according to  claim 13 , wherein the device has a skin-facing surface and a second surface facing away from the skin during use, with the release liner is disposed on the second surface, the method further comprising removing the release liner from the second surface of the device. 
     
     
         17 . The method according to  claim 13 , wherein the device is ring or oval-shaped with a through-going hole for fitting around a stoma of the user, the method further comprising placing the through-going hole around the stoma and attaching the ring or oval-shaped device to a skin surface surrounding the stoma.
