Antiseptic wipes

Abstract

A personal skin cleansing wipe comprising a flexible substantially dry matrix formed from synthetic, woven, non-woven or knitted fibers impregnated with a substantially anhydrous antimicrobial, antiseptic, antifungal solution in an amount wherein the matrix retains its substantially dry characteristics and the treatment solution includes an amount of PVP-iodine as active in solution in glycol and or glycerin. The treatment solution, in addition to an effective amount of PVP-iodine as active, contains surfactants, preferably Tego® Betaine CK D, and optionally a compatible fragrance and/or moisturizer. The wipe is activated with water just prior to use.

1 . A wipe comprising a flexible, substantially dry matrix having a moisture content of less than 1% comprising a matrix of synthetic, woven, non-woven or knitted fibers coated or impregnated with a waterless formulation antimicrobial treatment solution, said treatment solution including about 1.0 to about 15% by wt. of polyvinyl pyrrolidine iodine as antimicrobial or antiseptic and an anhydrous surfactant, in a non-aqueous solvent carrier selected from the group consisting of glycol, glycerin and mixtures thereof, said wipe being activated by wetting with water prior to use, for transferring said treatment solution to the skin or other surface on said water activation. 
     
     
         2 . The wipe of  claim 1  wherein said solvent is a glycol. 
     
     
         3 . The wipe of  claim 1  in which said non-aqueous solvent carrier is propylene glycol and is present in said treatment solution in an amount between about 25% and about 80% of said treatment solution. 
     
     
         4 . The wipe of  claim 1  wherein said solvent is a mixture of propylene glycol and glycerin. 
     
     
         5 . The wipe of  claim 1  in which the said matrix contains between about 50% and about 70% polypropylene and between about 30% and about 50% polyester fibers. 
     
     
         6 . The wipe of  claim 1  wherein said matrix comprises about 100% of polypropylene or polyester fibers. 
     
     
         7 . The wipe of  claim 1  in which said surfactant is a nonionic or a cationic surfactant or a mixture thereof. 
     
     
         8 . The wipe of  claim 7  in which said surfactant is present in an amount of less than about 40% by wt. of the matrix. 
     
     
         9 . The wipe of  claim 7  wherein said surfactant is a nonionic surfactant and/or a cationic surfactant and is present in an amount of about 0.50% by wt. to about 15% by wt. 
     
     
         10 . The wipe of  claim 1  wherein said surfactant is an amphoteric and is present in an amount of about 0.5% to 25% by wt. 
     
     
         11 . The wipe of  claim 1  in which said antimicrobial PVP-iodine in said wipe is present in an amount of from about 1.0% by wt. to about 15.0% by wt. 
     
     
         12 . The wipe of  claim 1  wherein said treatment solution contains Tego® Betaine CK D as surfactant. 
     
     
         13 . The wipe of  claim 1  wherein said treatment solution contains a fragrance. 
     
     
         14 . The wipe of  claim 12  wherein said Tego® Betaine CK D is produced by spray drying. 
     
     
         15 . The wipe of  claim 14  wherein said Tego® Betaine CK D contains less than about 1.0% of water. 
     
     
         16 . The wipe of  claim 1  wherein said matrix is substantially binder free. 
     
     
         17 . The wipe of  claim 1  wherein said treatment solution contains a moisturizer. 
     
     
         18 . A method of sanitizing skin comprising the steps of
 a. wetting a wipe according to  claim 1  with water,   b. wiping the skin using the water activated wipe, and   c. rinsing the skin with water.   
     
     
         19 . A method for producing the wipe according to  claim 1 , comprising impregnating said fabric by slot coating with said treatment solution, and cutting and folding said coated fabric. 
     
     
         20 . Method for sanitizing skin which comprises wetting the skin and scrubbing the skin with a wipe according to  claim 1  to produce a solution of the composition contained in the wipe and rinsing the skin to remove the solution and the killed bacteria, microbes, fungi and residual debris.
