Low alcohol content disinfection foams

Abstract

Disinfection foam having low levels of alcohol, comprising at least water, foaming agent, and polymeric type silver ion source, and a method of manufacturing the same. The present antimicrobial foams are especially suitable for hand sanitizer foams, shaving foams, dry cleansing foams for full body, leave on shampoos, face cleansing foams and multipurpose dry cleaning

1 . A disinfection foam or foamable composition having low levels of alcohol, comprising:
 water,   a foaming agent, and   a polymeric type silver ion source,   
       wherein said polymeric type silver ion source is obtainable by forming it without water. 
     
     
         2 . The foam or foamable composition according to  claim 1 , wherein the polymeric type silver ion source further comprises a silver salt of polyethyleneimine polymer being obtainable by freeing the polyethyleneimine polymer from water before mixing it with a silver ion source. 
     
     
         3 . The disinfection foam or foamable composition according to  claim 1 , wherein the polymeric type silver ion source further comprises a silver salt of polyethyleneimine polymer. 
     
     
         4 . The foam or foamable composition according to  claim 2 , wherein the silver salt of polyethyleneimine is derived from silver chloride. 
     
     
         5 . The disinfection foam or foamable composition according to  claim 2 , wherein the silver salt of polyethyleneimine is derived from silver lactate. 
     
     
         6 . The disinfection foam or foamable composition according  claim 1 , wherein the concentration of the polymeric silver ion source is 5 to 2000 parts per million. 
     
     
         7 . The disinfection foam or foamable composition according to  claim 1 , wherein the foaming agent is lauramine oxide. 
     
     
         8 . The disinfection foam or foamable composition according to  1 , comprising:
 water 50 to 100 parts by weight,   betaine 0 to 5 parts by weight,   a foaming agent 0.05 to 5 parts by weight,   an alcohol 0 to 5 parts by weight,   a polyethyleneimine 0.01 to 10 parts by weight,   a hydroxy acid 0 to 10 parts by weight,   a silver compound, 0.001 to 2.5 parts by weight, and   stabilizing compounds 0.001 to 2.5 parts by weight.   
     
     
         9 . The disinfection foam or foamable composition according to  claim 1 , wherein the alcohol content, in terms of the total weight of ethanol and isopropyl alcohol, is less than 2.0 parts by weight. 
     
     
         10 . The disinfection foam or foamable composition according to  claim 1 , wherein the disinfection foam or foamable composition is suitable for two or more purposes selected from the group of disinfecting, sanitizing and cleansing of humans, animals and inanimate objects. 
     
     
         11 . A method of producing a foam or foamable composition comprising the steps of: mixing together water, a foaming agent, and a polymeric type silver ion source, wherein the polymeric type silver ion source is formed without water. 
     
     
         12 . The method according to  claim 11 , wherein the polymeric type silver ion source comprises a silver salt of polyethyleneimine polymer. 
     
     
         13 . The method according to  claim 11 , wherein the polyethyleneimine polymer is freed from water before being mixed with a silver ion source. 
     
     
         14 . (canceled)
